It isn't too difficult to see that increasing speeds of wireless data communication and shrinking processors will eventually lead to the development of telepathic nanodots suitable for implanting in our brains... I'm in!




Ultrawideband: Wireless Whoopee
SAN FRANCISCO -- Think of it as Wi-Fi on steroids. On its way to U.S. living rooms and maybe even automobiles is a new type of high-speed wireless connection that promises downloaded data rates of up to 1 gigabit per second -- roughly 18.5 times the speed of Wi-Fi -- to personal computers and other devices.

This ultrawideband technology, which could become available in the next two years, also allows the devices to send data upstream to a network at 480 megabits per second.

The idea is to make it possible to do things like stream high-definition television signals throughout the home, send video shot on a digital recorder live across the internet, and even connect a digital music player to a car's stereo system -- all with a wireless connection.

Ultimately, ultrawideband chipsets could be installed in any electronic device -- such as a PC, set-top box, camera or tablet PC -- to enable really high-speed data transmission.

Dating back to the 1960s, ultrawideband was once a classified military technology whose earliest applications weren't so much in communications as in tracking stealth aircraft and the like, said Bruce Watkins, chief executive of Pulselink, a San Diego start-up focusing on the platform.

The U.S. Federal Communications Commission approved the technology for commercial use in February 2002. Since then, two competing camps have sprung up and are now working to establish a single standard.

Industry experts and analysts see ultrawideband complementing both Wi-Fi, which now transmits data downstream at up to 54 megabits per second, and ultimately WiMax, a high-speed wireless technology in the early stages of development that works over much greater distances.

"(Ultrawideband is) very inexpensive, works across short ranges, but has very high performance," said analyst Craig Mathias of market research firm the Farpoint Group.

The technology has won support from big chip makers like Intel, Texas Instruments and Motorola, spinoff Freescale Semiconductor, as well as smaller players like Pulselink, Israel's Wisair and San Diego's Staccato Communications. Electronics companies Sony, Philips and Panasonic are also embracing the technology.

"There is an effort underway to standardize ultrawideband," Mathias said. "And assuming that happens, we expect the market to be very big."

Aesthetically conscious consumers would appreciate the high-speed wireless streaming of HDTV signals through the home -- meaning, for example, no cables snaking up to the wall-mounted plasma TV.

The technology would also enable wireless USB 2.0 or FireWire connections, which transmit data at about 440 megabits per second. This would allow consumers to download photos, music, video and other data-rich tasks without having to plug the devices into their personal computers.

"Wireless USB would be a key application," Mathias said.

As for streaming HDTV signals, Ultrawideband is better than Wi-Fi, whose underlying technology isn't really designed for sending video images.

"If you want to start streaming high-definition television signals from your set-top box to your plasma display, Wi-Fi's technological underpinnings are not well suited for that," Pulselink's Watkins said.

At the same time, he said, the rapid transmission rate of Ultrawideband could even allow consumers to, in real time, broadcast DVD-quality video from a camera to friends and family over the Internet.

"They can watch the video while I'm filming it," Watkins said.

Thanks to Moore's Law, the 1965 observation by Intel co-founder Gordon Moore that the number of transistors on a single chip doubles roughly every 18 months while production costs are halved, the technology is becoming cheaper.

"Our chief technology officer likes to say that the equipment used to take an entire room and cost millions of dollars," Watkins said, "but now you can do the same thing on a microprocessor that costs a few dollars."

Eventually, the industry will hammer out a standard, and consumers could expect to see ultrawideband-enabled electronic devices in 2006, analysts said.

"The marketplace is as potentially exciting and high-growth as Wi-Fi," Mathias said. "But there are many twists and turns between now and then."

New Mexico City Hopes for Wi-Fi Access by Christmas By Wayne Rash
October 29, 2004

"We're a very tech-savvy community," said James Palenick, city administrator for Rio Rancho, N.M., explaining why his city of 63,000 was working to provide Wi-Fi access to its citizens.

"We've always wanted this to provide economic growth," he said. "It sends a very important message to the country and the world." And of course, it sends an important message to the citizens of Rio Rancho that the city has found a way to provide nearly ubiquitous broadband access for its residents as well as a new revenue stream for the city.

Wi-Fi also promises to help provide long term economic benefits to Rio Rancho by attracting companies that want the atmosphere that wireless broadband access can bring.

Palenick said that his city initially started working with Usurf America Inc to provide citywide Wi-Fi, but shortly thereafter decided to find a different vendor. That company turned out to be Ottawa Wireless Inc. of Grand Haven, Michigan, which had just finished implementing a citywide wireless network for its hometown.

According to Tyler Van Houwelingen, CEO and founder of Ottawa Wireless, the company will have as much as half of the citywide network up and running by Christmas. "Access points will be located on light poles, traffic lights and police antennas," Van Houwelingen said. "We'll install between 100 and 125 Wi-Fi POPs [points of presence]."

Ottawa Wireless expects to start installing the devices in November, with the system completed by mid-March. When it's finished, it will cover the entire 103-square-mile territory of Rio Rancho and will support VOIP (voice over IP) and QOS (quality of service) in addition to standard 802.11 wireless.

Palenick said that Rio Rancho's wireless installation would be the largest such Wi-Fi implementation ever. While he notes that other cities including San Francisco and Philadelphia have announced plans for citywide wireless access, Rio Rancho is actually doing it. Part of the reason for the strong interest is that the city boasts a very large number of citizens involved in science and technology.

Click here to read why an influx of lower cost chips is making Wi-Fi more of a commodity.

Rio Rancho is adjacent to Albuquerque, and is the location of what Palenick says is Intel Corp.'s largest microprocessor factory. In addition he noted that his city is located between Los Alamos National Laboratory and Sandia National Laboratory. Of course, there are other reasons. "We see it as an economic development tool—today's business needs good quality access, Palenick said.

Palenick also said that the city itself needs the broadband wireless connectivity. "We're permitting 3000 new single-family houses a year," he said, noting that such access would allow inspectors to do their work without returning to the office. In addition, he said that there were significant public safety requirements for broadband access.

The city has worked out a license agreement with Ottawa Wireless that resembles a cable television franchise in some ways. The city gives Ottawa Wireless access to public right of way. In return, Ottawa Wireless will pay a fee for being allowed to operate in the city. Palenick said that the fee is 3 percent of the gross after the company receives $100,000 gross per month. That fee goes up to 5 percent for revenues between $300,000 and $500,000. Once monthly revenues reach $500,000, the fee goes to 7 percent.

Van Houwelingen said that he expects his company to start seeing significant revenues early on. He noted that the basic rate for a fixed wireless installation would be $19.95 per month for access speeds of 256K bps. A mobile wireless user would pay $5 more per month. Higher speeds are available at higher rates.

Van Houwelingen said that his company can implement the citywide Wi-Fi network quickly because relatively little infrastructure is needed. Each of the Wi-Fi POPs has a wireless backhaul connection provided through a Proxim microwave link working over a point-to-point or point-to-multipoint connection. He said that this allows the company to add POPs as needed, and to seamlessly provide upgrades and improvements as necessary.

Click here to read about technology advances that should produce improve Wi-Fi repeaters in 2005.

Van Houselingen said that he expects the service to be very popular with individuals and businesses, in part because it will be very inexpensive to put into place. He said that most people with computers that are already capable of using Wi-Fi can simply start using the service once it's running. He also said that Ottawa Wireless would be providing Wi-Fi-to-Ethernet bridges for those with a need for wired access, or for companies that needed to have separate networks.

"This might force other service providers to break down their costs," said Julie Ask, senior analyst for JupiterResearch in San Francisco. Ask also said that winning a significant portion of the business in Rio Rancho could be an uphill battle. "I think it's going to be hard to unseat an incumbent," she said. "All they have to do is lower their price and the game has changed."

Ask said that while Ottawa Wireless is offering an attractive price, existing DSL and cable providers are providing much higher quality connections. In addition, she noted that these organizations already have call centers and customer service. "The economics aren't clear in terms of the cost," she said.

On the other hand, Ask noted that the Rio Rancho implementation is the only one with a clear timeline. She also felt that the fact that this had the backing of the city was important. "It's good that the cities feel it's important that their citizens have access to broadband. We will see more of this," she said.

Continuously Networked - the 'Always on' Society

November 03, 2004
In the "always on" society of the future, we’ll be able to continuously keep in touch with the whole world, if we choose—regardless of which terminals we use and without having to think about how the data is transmitted. Siemens is creating devices and networks to meet just these challenges.
In the future we will communicate more - and with more mobility - than we do today. We’ll be able to receive our e-mails on our cell phones and handheld computers. Thanks to technologies like UMTS and WLAN, we’ll be able to access the software we use in our offices and our private data - from anywhere. In industry, real-time communication will change manufacturing, because all the data for controlling processes will be available anywhere and anytime. The Internet will become faster and more mobile. On our cell phones, we’ll be able to see which of our friends are online and where they are.

And the forms of communication will merge. In the foreseeable future, fixed-line networks, mobile radio networks and the Internet will seamlessly blend into one another and form the overarching environment for different transmission standards. Siemens’ LifeWorks concept already offers a platform for a variety of networks and, with applications such as HiPath OpenScape, the possibility of being accessible anywhere in the world at one number.

The Internet will soon be as omnipresent as the electricity that comes out of your socket. One current trend in telecommunications is to be "always on" (online).

An important goal is the seamless transfer between different technologies. Users shouldn’t notice which transmission standard their laptop, cell phone or PDA is using—whether it’s WLAN or WiMAX, UMTS or HSDPA.
Several different standards will co-exist over the next few years, but fixed-line networks, mobile networks and the Internet will ultimately merge.

Cell phones become walkie-talkies. One of the first cell phones to accommodate mobile mailing is the new Siemens SK65, which was introduced in August 2004. The device has an e-mail feature from the U.S. company RIM that was previously only available in the rather quirky BlackBerry devices. A special server automatically sends e-mails to the user’s cell phone and office PC. The calendar and address book can be synchronized and company data accessed.

But to be always online, seamless switching must be feasible. Siemens developers have built a demonstrator that makes it possible to change networks during a call. The caller uses a data card in a laptop or PDA to call via either the company network (Ethernet), a WLAN or the UMTS network. If the user leaves the office during the call, the Ethernet connection is cut off. The VoIP data packets then automatically take the most efficient route depending on the availability of other networks. The unit also allows the UMTS network and WLANs to be simultaneously used to increase the transfer rate if large amounts of data need to be sent. The system won’t be ready for market launch until at least 2005.

Next year, Siemens will introduce a UMTS cell phone with an integrated WLAN. This requires a unit equipped with two chips. And Siemens Com developers are even working on integrating different transmission standards on a single chip, with the Software Defined Radio (SDR) system. With SDR, a hard-wired chip architecture will no longer decide the frequency a terminal can transmit or receive in. Software installed in the unit will decide, so one cell phone can function in all networks. "I can imagine a market launch for such a comprehensive solution at the end of the decade," says Holger Landenberger, SDR Project Manager at Siemens Com. "We’ll proceed gradually and first incorporate several standards, like UMTS, GSM and WLAN." Product development can begin in mid-2006, says Landenberger, who adds that Siemens would enjoy cost benefits from manufacturing cell phones with SDR. For example, with the new software it would be possible to decide which transmission standard and regional market to equip the unit for after assembly.

Gbit/s with your cell phone? Siemens is also lead partner in the EU-sponsored WINNER research project. The project’s 40 partners plan to develop a universal radio technology to supplement current standards after 2010. One goal is to achieve data transfer rates of up to 1 Gbit/s at distances under 100 m, and approximately 100 Mbit/s for a broader radius. In the laboratory, Siemens developers have already achieved data transfer rates of 360 Mbit/s with a carrier frequency of 5 GHz and a bandwidth of 100 MHz, divided into 256 subfrequencies using Orthogonal Frequency Division Multiplexing (OFDM). This reduces the effect of echoes, which often occur at such a high carrier frequency due to reflections from buildings, for example. The researchers are also using wireless "multihop stations"—a combination of base station, repeater and router. Thanks to such stations, signals can be redirected around obstacles and amplified. During a recent field study in Munich, these multihop stations significantly increased the range of such radio systems. Researchers are also working on a combination of several antennae (MIMO) to raise the transmission rate to 1 Gbit/s. So at least data transfer rates would no longer pose a problem for realizing the always-on society.

But one limit will always exist: U.S. mathematician Claude Shannon, who invented the concept of the bit and founded information theory, calculated 50 years ago that, depending on transmission bandwidth and ambient noise, there is a theoretical limit to data transfer speeds. A cell phone could receive a maximum of 100 to 1,000 Gbit/s—if such a super cell phone doesn’t start smoking from all that data.

Many Roads Lead to the Mobile Internet

Key technologies:

UMTS (Universal Mobile Telecommunications System): Standard for third-generation mobile communications (3G); operates in specially licensed frequency bands in the 2-GHz range. Its theoretical maximum data transfer rate is 2 Mbit/s. But there are two limits to any type of mobile radio technology: First, all users of a given cell share the available capacity. Secondly, the maximum data transfer rate decreases when the user’s speed of movement increases. In practice, UMTS achieves a rate of 384 kbit/s when downloading data (downlink).
HSDPA (High Speed Downlink Packet Access): A further UMTS software development, with a maximum downlink data transfer rate of 14.4 Mbit/s. The base station’s capacity can be increased by 50 % by optimizing the modulation and coding algorithms and by making distribution of the data load at the base stations more efficient. Siemens network technology already supports the HSDPA protocol; so the only thing still needed for implementation is a software update. Siemens also plans to introduce an HSDPA card for laptops at the end of 2005. Thereafter, cell phones will also support the HSDPA standard.
WLAN (Wireless Local Area Network): A locally limited radio network operating in frequencies not subject to licenses. Inside a hot spot with a range of 10 to 50 m, a WLAN achieves maximum data transfer rates of 11 Mbit/s (Standard IEEE 802.11b at 2.4 GHz) and 54 Mbit/s (IEEE 802.11a at 5 GHz; or IEEE 802.11g at 2.4 GHz).
WiMAX (Worldwide Interoperability for Microwave Access): An expansion of WLAN. Like WLAN, WiMAX transmits data packets (small packets, like on the Internet) at frequencies of between 2 and 11 GHz; the data transfer rate can reach 75 Mbit/s. Depending on the standard (IEEE 802.16a, b, d, e, g), a range of several hundred meters to several kilometers is possible. Here too, all users share the data transfer capacity. Unlike with UMTS, WLAN and WiMAX users’ speed of movement is restricted—to a maximum of walking speed. Siemens is developing a solution for WiMAX networks that’s scheduled for market launch in the summer of 2005. Along with a base station, the package will consist of integration support and other services. Intel plans to begin installing WiMAX chips in notebooks in 2006.
GSM, GPRS und EDGE: Standards for second generation mobile communications
DECT: Standard for cordless telephones
Bluetooth: Standard for wireless communication between devices in a limited area

WiMax May Pose Fresh Challenge to Broadband

By Reuters
February 27, 2005


NEW YORK (Reuters) - Imagine a wireless hotspot the size of Philadelphia or a rural community in the American heartland.

U.S. cities and companies are eyeing an emerging technology known as WiMax as a way to make high-speed wireless Internet services available in areas much larger that a typical Wi-Fi coffee bar or the local McDonald's. But it may prove difficult to make such services commercially viable, analysts say.

WiMax—touted as a potential spoiler for cable modems and other traditional Internet connections—was developed to beam the Internet across cities using radio networks with much wider ranges than Wi-Fi, a system used on laptops in coffee shops.

Some broadband operators are considering WiMax as a way to expand their networks, and city administrators are looking to offer broadband services cheaply in public places such as parks or in low-income housing areas.

Such networks could erode the market for services such as cable modem and digital subscriber line (DSL) access over traditional phone lines. But the scarcity of suitable airwaves and wide availability of DSL and cable could stunt WiMax growth at least in the United States in the next few years.

"The WiMax market in other geographies will dwarf that of North America," said Forrester analyst Charles Golvin, who believes WiMax makes more sense for some parts of Europe and developing countries where broadband is not very common.

Companies including chip giant Intel Corp. and network gear makers such as Alcatel , Lucent Technologies and Alvarion plan to sell WiMax products. Early versions that deliver the Internet to fixed locations such as homes are expected to go on sale next year.

But U.S. WiMax providers will be cautious about where and how they operate because if WiMax is added to a crowded market. The fear is that profit margins could suffer at both the WiMax operator and incumbent broadband providers, analysts said.

"Increased broadband competition, price compression and high subscriber acquisition costs threaten to drive margins ever lower," said In-Stat analyst Keith Nissen who expects only 3 percent of broadband users around the world will use WiMax services by 2009. It could cost about $3 billion to build a nationwide U.S. WiMax network, according to In-Stat estimates.

Roughly 85 percent of U.S. households can now buy broadband services and about 70 percent have a choice between cable and DSL, according to Yankee Group analyst Patrick Mahoney.

This means that most commercial WiMax services are likely to be small in scale as markets would be limited to hard-to-reach rural areas or city neighborhoods that are not already hooked up for broadband, Yankee's Mahoney said.

Municipal administrators in as many as 100 cities or towns are looking at building wireless networks, said Forrester's Golvin who noted that these could projects range from coverage of entire cities or towns to links between official buildings.

For example, the City of Philadelphia hopes to build a network to interconnect Wi-Fi networks. It could potentially use WiMax in about 60 percent of the city, officials said.

Some regional operators are eyeing WiMax as a way to extend their networks and to avoid the high costs of putting new wires in the ground. But so far, none have made firm service plans and airwaves availability could also be problem, Golvin said.

Local phone provider BellSouth Corp. is testing an early WiMax system. It says it has suitable airwaves across its nine operating states and hopes to have a service next year.

But first it needs to work out equipment costs and consumer demand before committing to service plans. It is also working out how it can avoid potential interference between its airwaves and satellite services using similar bands.

"If it can save money and provide a high-speed broadband service and we can make a profit on it, then we'll do it," said spokesman Jeff Batcher, noting that WiMax should be cheaper to provide than services such as DSL which BellSouth sells.

Qwest Communications International Inc. , which provides local services in 14 states, has also tested WiMax. It does not own airwave licenses but says it would consider buying licenses or using unlicensed airwaves.

Golvin believes that using unlicensed spectrum would be too risky for operators such as Qwest. Since anybody can use unlicensed spectrum it is difficult to control service quality as other users of the same band could cause interference.

Sprint , the No. 3 U.S. mobile provider, is likely to be the biggest U.S. WiMax provider as it will own airwaves suitable for the technology in 80 of the top 100 U.S. markets after it buys Nextel Communications Inc. this year.

It plans to test early versions of WiMax that transmit to fixed locations but it will wait for a mobile version before launching services around 2008. It says it needs mobility to compete better with entrenched broadband providers.

Many analysts believe mobility could make WiMax a more viable competitor to cable or DSL but caution that a technology standard has yet to be agreed for mobile WiMax.

Seattle-based Clearwire, which is run by wireless pioneer Craig McCaw and counts Intel among its investors, has also endorsed WiMax. It has WiMax-like services in four U.S. markets and plans to add another 16 markets by year-end.

But Spokesman Todd Wolfenbarger said it was too early to predict how successful these services would become.

"I think we're cautiously optimistic about it," he said.

Why? How will advancing connection lead to nanobots?

I understand that nanobots need fast and wireless connection, but I don't see how connection-technology itself will bring forth these nanobots.

Dishnet Aims for India-Wide WiFi Coverage in 2 Yrs By Reuters
May 4, 2005

NEW DELHI (Reuters)—India's Dishnet Wireless Ltd. said on Wednesday it aims to dominate the nascent WiFi mobile Internet market by rolling out nationwide service in two years.

Dishnet will use WiMax base stations to link WiFi "hot spots," where properly equipped devices like laptops can download data wirelessly at up to 512 kilobits/second. It aims to be India's largest WiFi provider, with 6,000 hot spots in 38 Indian cities.

WiFi technology can provide Internet connectivity at distances from a few meters to up to 50 km (30 miles) with WiMax, whose networking supports WiFi transmitters.

"We expect a subscriber base of 200,000 users when we finish our rollout in 18-24 months," V.G. Suri, Dishnet's vice-president for marketing, told reporters, adding that the cafe outlets of Barista—run by Dishnet's owner—would be key usage points.

The firm is targeting heavy users like companies as well as price-conscious students and families.

Suri said Dishnet had spent 2.5 billion rupees ($58 million) on the wireless network, whose expansion will be funded from future sales. The firm expects 1.07 billion rupees in revenue for the current fiscal year to March 2006, he said.

Madras-based Sify Ltd., which had an early start in the WiFi business, has an active broadband service, but is yet to start the wide-range WiMax service.

Though India is experiencing a mobile telecoms revolution because of rock-bottom call rates, Internet and broadband usage continues to be hobbled by an archaic fixed-line infrastructure.

The government is pushing for faster Internet access in Asia's fourth-largest economy by freeing up several frequency bands and is mulling some tax breaks to make equipment cheaper. It has targeted 3 million broadband customers by December.

Broadband penetration is low in India, where only two in 10,000 people have a high-speed hook-up, compared with one in four in South Korea. Digital subscriber line connections are the main route by which India expects to boost access. ($ 1 = 43.52 rupees)

Is there any reason why an individual couldn't distribute their own broadband cable feed via WiMax to themselves in a metro area for wireless internet and skype without paying any additional monthly fees? I'm building a house and it should be done around December. Any holes in this scenario?

First of all security and second who is providing the basic transmit/receive system?

If you are providing it you will still pay for bandwidth for accessing the internet to your server I suspect. You certainly will be responsible for the power and equipment requirements, as well as transmission licenses for sending that signal out farther than a pretty local area.

I'm building a house and it should be done around December. Any holes in this scenario?


There are plenty of WiFi hubs for home use now but all of them have major security flaws (holes) that allow others to not only hack you for unencrypted data all too easily but also to be *whacked* for use as a cheap on the sly hotspot when some neighbor finds your operating frequency. Their current range is generally measured in parts of a mile, like cordless phones.

I am a bit unclear about how the FCC is determining licensing requirements at the moment but in the case of recent Pirate Radio related legislation it had to do with signal strength for designated public access *non* license required frequencies. IOW calling them *unregulated* is often misleading if like CB and many FM frequencies you have a 5 to 15 watt transmission power limit.

This obviously restricts the range in which a signal is usable without repeaters and/or increasing antenna height off the ground (also subject to zoning and license in many areas, especially metropolitan ones).

Do a few searches on this and I bet you can self educate fast.

It is relatively simple to secure a home wireless network...

The costs of licencing long distance wireless would prohibit personal use over a wider area.. for now at least.

Korea Pushes Wireless Vision

Striving to keep its IT lead, Seoul appears anxious to create a nation of gadget freaks.
June 25, 2005

SEOUL – In today’s South Korea, everyone from government agencies to telecommmunications carriers to equipment vendors is chanting in unison what may well be the new national mantra: “anytime, anywhere, and on any device.”

The word ubiquitous has become just that. Creating a “u-Korea” is the goal in Seoul’s aggressive push to stay in the global vanguard of information and communications technology.

Behind this government-led drive is a deep-seated fear that South Korea’s IT boom will slow as the country nears saturation. Already, South Korea counts 35 million mobile subscribers out of a total population of only 47 million. Broadband penetration is the highest in the world, with 12 million high-speed Internet subscribers.

“Korea has entered into a mature period characterized by slow growth,” said Yong-Kyung Lee, president and CEO of telecom operator KT, in a keynote address delivered at the u-Korea Vision Conference 2005 on Wednesday.

Working in close coordination with carriers and major vendors like Samsung and LG, government agencies like the Ministry of Information and Communication (MIC) and the National Computerization Agency (NCA) are pushing hard to move the ICT sector into new growth areas.

Homegrown Wireless

Already, a host of homegrown technologies are making their way into the Korean market. This year, South Korea launched satellite-based digital multimedia broadcasting (S-DMB) service, which beams radio and video programming as well as data to small devices, and plans to launch terrestrial DMB (or T-DMB) service in 2006 (see Showtime in South Korea).

SK Telecom is rolling out a second 3G network—this time, a WCDMA (wideband CDMA) network—alongside its existing CDMA 2000 1x EV-DO network. And both SK Telecom and rival KT have been issued licenses for WiBro (wireless broadband), the mobile-enabled Korean version of the 802.16 standard known as WiMAX (see Hanaro Pulls Out of WiBro).

The new services are part of the MIC’s IT 839 Program (see South Korea: Fighting to Stay on Top), which targets eight key services, three major infrastructure projects, and nine “cash cow businesses” for promotion and development with government assistance and guidance.

The strategy of cooperation between government and industry to push popular adoption of new technologies has worked before. But questions remain over just how quickly Korean consumers will take up the latest gizmos.

Faith in Adoption

Government officials and telecom carriers alike place enormous faith in the virtually limitless capacity for adoption.

“This has a lot to do with the cultural characteristics of Koreans,” said Seung Yun Ahn, vice president of the content business division for South Korea’s leading mobile operator, SK Telecom. “As new products and services are rolled out, Korean people desire those products and services.”

“Korean people like following trends,” said Moah Lee, 22, who bartends by night at a basement dance club called Spin in Seoul’s Apgujeong nightlife district and majors in fabric arts at Kyungwon University by day.

She turns up her nose at the technological herd instinct of her countrymen. Her Samsung handset is a plain old CDMA 1x phone—not a 3G phone—and she has no plans to buy a DMB handset.

“I don’t care what the government is pushing,” she said. “I don’t watch TV or read the newspapers.”

Ms. Lee, who lived in Canada and has traveled in the United States extensively, now wants to learn to be a DJ like her boyfriend, Yo Sang, and is looking into DJ schools in the United Kingdom.

“Korea is so boring,” she said. “There’s a boom, and everyone follows.”

But Ms. Lee isn’t immune to the trends herself. Like 12 million other mostly young Koreans, she keeps a photo blog on the immensely popular Cyworld.com service offered by SK Telecom affiliate SK Communications.

Ms. Lee has heard about the u-Korea vision—robotic vacuum cleaners, digital paintings that change from Kandinsky to Monet by voice command, RFID tags to make shopping even easier—but she isn’t in a hurry for Korea to embrace it. “It’s just not very human,” she said.

Huge Integration

“Society will become radically improved. All objects will be targets of huge integration, creating a society where cyberspace and the physical world are physically merging,” said Chang-Kon Kim, president of the NCA in his keynote address at the u-Korea Vision Conference. “The question is how Korea must prepare for the future of the new society.”

A glimpse of the future is available in the MIC’s Ubiquitous Dream Hall. Wireless ID tag secured to his wrist, the homeowner of tomorrow speaks a few commands and taps a couple of touch screens. The interactive, intelligent operating system that links his home theater, refrigerator, and even bathroom mirror pretty much does the rest—drawing shades and dimming lights for a movie, warning him about expired ham in the fridge, offering recipes from available ingredients, and telling him what pants in his closet might match the shirt he’s picked out.

Wireless wonderland, or chilling techno-dystopia?

Even Mr. Kim concedes he’s not fully prepared for that future. Asked later that evening whether he would want to live in such a world, Mr. Kim smiled, shook his head, and said, “Well, some parts of it, yes.”

Phone Giants Try to Block Towns' Wireless Internet
from http://www.rednova.c...towns_wireless/

GRANBURY, Texas -- After years of waiting for a local phone company to roll out high-speed Internet access in this growing lakeside town of about 6,400 people, municipal information- technology director Tony Tull took matters into his own hands. The city last year invited a start-up telecom firm to hang wireless equipment from a water tower and connect the town.

The network now provides high-speed wireless Web access to most of Granbury, and the town is negotiating to buy some of the equipment. But Granbury's foray into the wireless business has propelled it into a battle between cities and technology companies on one side and big telephone companies on the other.

SBC Communications Inc., the dominant phone company in Texas, and other big phone companies say cities should not be allowed to subsidize high-speed Internet connections - even in areas where the companies don't yet offer the service. Since January, lawmakers in at least 14 states and the U.S. Congress have introduced bills to restrict local governments' ability to fill the gap.

On the other side of the fight, along with Granbury and dozens of towns like it, are Intel Corp., Dell Inc., Texas Instruments Inc. and other tech companies. They stand to gain from the sale of chips, wireless-enabled laptops and other products that use fast Internet networks.

Around the country, governments are contracting with providers other than the local telephone or cable companies to build or run the networks using Wi-Fi technology or fiber-optic cables. Wi-Fi, short for wireless fidelity, provides high-speed access to the Web.

Traditional telecom providers view such projects as a threat and are pushing for laws to curtail them. While the phone and cable companies control the valuable "last mile" wired connections into homes and offices, the wireless networks use antennas to bypass those lines and can connect directly to the networks of long- distance companies or fiber-optic providers. Plans for such government-coordinated networks are spreading from rural America to larger cities including Philadelphia and San Francisco, and big phone companies have stepped up their efforts to stop them.

The battle is increasingly significant as telephone companies like SBC count on their high-speed Web access businesses - which generated roughly $5 billion in revenue last year, nearly double the amount two years earlier - to offset declines in their traditional telephone operations.

The telecom providers' main tool in fighting competition from new wireless technologies is an old-fashioned one: lobbying muscle. The nation's phone companies, which themselves received more than $5 billion last year in federal subsidies, argue that government partnerships with telecom providers represent unfair competition.

The industry effort is meeting with some success. Earlier this month, the governors of Colorado and Nebraska signed into law bills that restrict government telecom initiatives. Late last year, Pennsylvania enacted a law that requires cities to seek permission from local phone companies before offering any paid telecom services. Verizon Communications Inc., the dominant carrier in Pennsylvania, had pushed hard for the measure, arguing that government plans would discourage it from further investing in its network. Philadelphia's plan for a citywide wireless network has been grandfathered under the law.

The high-speed networks, sometimes referred to as broadband, offer an always-on connection to the Internet at speeds several times faster than dial-up. They are used for more than surfing the Web. High-speed Internet connections facilitate home health-care monitoring and video conferencing. And customers increasingly are using their fast connections to make phone calls, bypassing telephone companies altogether.

The legislative fights come as the U.S. remains behind many other countries in per capita broadband usage, ranking 12th, according to a recent study by the Organization for Economic Cooperation and Development. In part, that's a result of the country's size and its early lead in dial-up connections. Unlike many other countries, the U.S. has mostly left broadband rollout to private industry.

Granbury is only about 35 miles southwest of Fort Worth, and people who move into town often are surprised to find they can't get cheap, high-speed Web access. In 2001, San Antonio-based SBC installed some high-speed connections, but the company still hasn't rolled out its network to the entire town. According to SBC, only about 20 percent of the town is wired with digital subscriber lines, or DSL, the technology SBC uses for high-speed Internet service. In Texas, lines serving 25 percent of SBC customers haven't been upgraded.

DSL technology works only within a certain distance from the hub for a telephone company's network equipment, usually about 14,000 feet, SBC says. Because hubs are expensive to build, SBC and other telecom companies often initially limit the rollout of DSL to neighborhoods close to existing hubs.

Granbury has other providers, including Internet Texas, a local service provider, and Charter Communications Inc., a cable operator. But they don't provide complete or affordable coverage to the entire city, according to Mr. Tull.

In late 2002, when Mr. Tull arrived as the city's first technology director, he found that the municipal government had only six email accounts, and some of its 70 computers didn't even have dial-up Web access. Government employees couldn't easily share documents because there was no network connecting the buildings and the speed of Internet service was painfully slow.

Seeking alternatives, he talked with Charter about equipping the municipal buildings with high-speed Web access using fiber-optic cable. Charter's price tag, $875,000, was too expensive, he says. Charter confirmed the talks but declined to discuss the price.

Mr. Tull eventually contracted with a tiny start-up, Frontier Broadband LLC, one of hundreds of rural wireless Internet service providers that have sprung up across the country. The company installed antennas using equipment from Motorola Inc. on a water tower and on a city-owned radio tower in the local cemetery, providing high-speed access to city hall, two firehouses, a wastewater treatment plant and the local airport.

Last November, Frontier started equipping the entire city with Wi- Fi equipment from Tropos Networks Inc., an equipment maker that specializes in citywide wireless networks. Intel was an early Tropos investor. Among Mr. Tull's goals was providing Web access to police cars so officers could check records on the road. He and Frontier later expanded the plans to offer paid, high-speed wireless Web access to residents and businesses, with customers paying Frontier.

So far, roughly 60 percent of the city is covered, according to Mike Timmins, a co-owner of Frontier. Frontier paid for the equipment and its installation, but the city now is talking with Frontier about purchasing the entire Tropos network - as well as additional equipment to cover the rest of town - at a total cost of about $300,000.

Frontier will continue to manage the network and provide technical support. Out of the regular monthly charges of about $19.95 that subscribers pay to Frontier, the city will collect $3 per subscriber each month to recoup the cost of the equipment. "The entire capital outlay is shared," Mr. Tull says.

Craig DeWitt moved his five-person insurance agency to Granbury from Fort Worth in October 2003 but was surprised to learn DSL service wasn't available from SBC. He pays $87.45 a month for Frontier's service for the five computers in his office.

In February, Rep. Phil King, a Republican who chairs the regulated-industries committee of the Texas House of Representatives, introduced a 332-page bill aimed at overhauling the state's telecom regulations. Buried on page 87 was a provision to extend an existing ban on municipalities offering telephone service to also include other telecom offerings, like Wi-Fi.

When Mr. Tull learned about SBC's efforts to persuade legislators to restrict municipal wireless projects, he says, "I figured our project was dead." Mr. Tull twice traveled to the state's capitol in Austin to argue against the proposed legislation. Representatives of many other Texas towns did the same.

SBC is a huge political player in Texas. Last year, the company spent more on state lobbying than any other company or organization, laying out at least $3.9 million, according to Texas Ethics Commission records compiled by the nonprofit group Texans for Public Justice.

"It's not government's role to become a provider," says Jim Epperson, senior vice president for state legislative affairs at SBC. He points to towns that have run into costly failures offering telecom services, and says such spending could force towns to "lay off police officers or shut down libraries."

Mr. Epperson says towns without broadband should consider offering tax incentives to companies like SBC to encourage them to upgrade their networks.

The anti-Wi-Fi legislation moved the tech-equipment industry to action. Dell's founder and chairman, Michael S. Dell, telephoned members of the Texas House, including the speaker, Tom Craddick.

For companies like Dell, Intel and Texas Instruments, the spread of broadband is crucial. Dallas-based Texas Instruments, for example, makes chips for cable and DSL modems and for Wi-Fi routers. The company also makes chips for digital cameras and music players, which increasingly can be used with high-speed Web connections to share photos and songs. Dell, based in Round Rock, Texas, now includes Wi-Fi in most of its new laptops.

And Intel, of Santa Clara, Calif., has made Wi-Fi a centerpiece of its strategy, bundling Wi-Fi and other chips as part of its Centrino technology, which has been heavily advertised during the past two years. Intel has provided funding for several cities to help set up neighborhood-wide wireless networks.

"We believe that with Texas and the U.S. continuing to lag behind in broadband penetration, now is not the time to limit choices," says Michael Young, who oversees Dell's state-level lobbying.

On May 30, the Texas bill containing the anti-Wi-Fi provision died after cable companies lobbied against the bill. The cable operators objected because the legislation would have made it easier for telephone companies to offer competing television services.

The fight now has moved on to the national stage. Late last month, U.S. Rep. Pete Sessions, a Texas Republican, introduced the "Preserving Innovation in Telecom Act of 2005," which seeks to prohibit local governments or "any entity affiliated with such a government" from providing telecommunications service in any area where a corporation offers "a substantially similar service."

"I don't think governments should be in these businesses," Mr. Sessions says in an interview. "That's not their core business."

Mr. Sessions worked at Southwestern Bell, SBC's predecessor, for 16 years. His wife still works for SBC. During his eight years in Congress, SBC's political-action committee, its employees and their families collectively have been his second-largest source of campaign contributions, donating a total of $75,346, according to the Center for Responsive Politics, a Washington research group. Guy Harrison, Mr. Sessions's chief of staff, says the congressman's ties to SBC do not present a conflict of interest.

The telephone industry is fighting the battle on other fronts as well. The New Millennium Research Council, a think tank in Washington, issued a report in February condemning publicly funded Wi-Fi projects, arguing, among other things, that they stymie competition. The council is a project of Issue Dynamics Inc., a public-affairs and consulting firm that has done work for several of the country's major telephone and cable companies, including SBC, Verizon, BellSouth Corp. and Comcast Corp.

Some powerful federal lawmakers are rallying to the side of the cities. Sen. John McCain, an Arizona Republican, and Sen. Frank Lautenberg, a New Jersey Democrat, plan to introduce Thursday the "Community Broadband Act of 2005," stipulating that no state can prohibit a municipality from offering high-speed Internet access to its citizens.

Meanwhile, Granbury is continuing its rollout of municipal Wi- Fi. All eight of the city's police cars now have the service. Building inspectors are accessing the Web via wireless laptops. Frontier will start rolling out the network to the entire city next week and plans to finish it in about a month.
