(InfoWorld) - The first generation iPhone is barely on the streets, but some users and analysts are already talking about when a second-generation model will be launched to take advantage of faster 3G wireless network speeds for speedierÂ  Internet browsing. The first version of iPhone supports AT&T's EDGE -- Enhanced Data Rates for GSMÂ  Evolution -- network, a 2.5G network advertised as providing download speeds ofÂ  70Kbps to 135Kbps AT&T and Apple chose that network because it isÂ  the largest network, reaching 270 million people,Â company officials said last week. However, several analysts and reviewers believe that the next-generation iPhone, which could ship early next year in the U.S., will be provisioned toÂ  handle a faster 3G network, such as AT&T's High Speed Downlink Packet AccessÂ  (HSDPA), to support download speeds of 400Kbps to 700Kbps. However,Â  AT&T and Apple would not comment Thursday on their plans or a timetable forÂ  iPhone 2.0 or AT&T's HSDPA. AT&T spokesman Mark Siegel stressed that "HSDPA is available in 160 metro areasÂ  and AT&T will continue to build it out through the rest of the year, soÂ  obviously we're continuing to build 3G. " But Siegel also repeated comments made last week that iPhone users will acceptÂ  the slower EDGE speeds, especially since the iPhone can access faster WiFiÂ  networks when a hot spot is available at home or a coffee shop. "We haven't hadÂ  many complaints about EDGE," he said. "What really matters for a real humanÂ  being using the iPhone who doesn't know anything about EDGE is that this isÂ  going to be a great experience in totality, whether searching for a stock quoteÂ  or a map or many other things. We think overwhelmingly that people will beÂ  thrilled using this device. The experience they have on EDGE will be a reallyÂ  good one." Siegel's comments, however, don't match user consternation about EDGE speedsÂ  registered atÂ theÂ MacRumors forums, or concerns raised by some reviewers, including one who said itÂ  took two minutes to download the Yahoo Web site home page. The discussion thread at MacRumors asked people to post their EDGE speeds overÂ  iPhone using a network measuring tool. Some reported speeds were higher thanÂ  those advertised by AT&T, but most were slower, with 64Kbps on July 3 inÂ  San Diego and 71Kbps in Los Angeles that same day. "Boooooo!" is the onlyÂ  comment from the San Diego user identified as FreeState. GnarleyMarley87 inÂ  Atlanta reported 126Kbps in Atlanta on EDGE, but 1,245 Kbps over WiFiÂ  at home. Other uses weighing in on Macrumors about the differences between 3GÂ  and EDGE and why Apple is waiting indicate that iPhone users are aware thatÂ  AT&T's 3G network is not widely available in the U.S. Users also noted thatÂ  3G-capable phones consistently run down batteries faster than those on slowerÂ  networks. One analyst, Ken Dulaney at Gartner, recently confirmed that aÂ  3G phone can use up a battery at a rate 30 percent faster than a 2.5G phone. Apple officials would not comment on a timetable for the next iPhone release,Â  or even whether it will support 3G. Two analysts tended to support the decision to release the first iPhone overÂ  EDGE in order to get the broadest network reach over higher bandwidth. "EDGE isÂ  not a show-stopper for iPhone, and I think the next version will likely haveÂ  3G," said Michael King, an analyst at Gartner Inc. King said some industry experts believe Apple can have a second generation device ready by October, but that Apple won't unveil them so closely behind theÂ  first version's June 29 release. King believes AT&T's HSDPA network will beÂ  more widely available for U.S. users in late 2008. "It's a pretty usableÂ  network now," he said. With a second generation iPhone, Apple is also likely to support QuickTime, giving access to streaming video that will also use more bandwidth that willÂ  tend to require a 3G network, King said. Shiv Bakhshi, an analyst at IDC, said that Apple was "wise to have chosen unibiquitous network reach over bandwidth ... a culture of mobile data consumption in the U.S. is only beginning to set in. By the time it takes hold,Â  Apple will be out with 3G iPhones and AT&T will likely roll a 3G HSDPA networkÂ  across its national footprint." Asked when both will happen, Bakhshi said "in under a year." But Bakhshi said that it is not clear how much current iPhone users will be downloading from the Web. Songs and video can be imported from a PC, so EDGEÂ  speeds might not be an impediment for the average user. "Every network falls short as your expectations rise higher," he said."SomeÂ  people will always be high-end users and will find EDGE really frustrating, butÂ  for the average Joe Blow like you and me, it will suffice." Bakhshi said that data usage may not be the biggest driver of iPhone sales."The single biggest driver of iPhone may not be data usage," he said. "Instead,Â  it might be just its ability to invoke envy in your friends." Â

WiMax earned an important seal of approval on Thursday when the Radiocommunication Sector of the International Telecommunication Union (ITU)&#160;certified it as a 3G mobile data technology.Heavily promoted by Intel and sometimes criticized as overhyped, WiMax is based on industry standards but has been the young upstart in the telecommunications industry. With this week&#39;s decision in Geneva by the radio group, also called ITU-R, it can finally rub shoulders with widely deployed technologies such as WCDMA and CDMA-2000.Many governments dictate technologies when they allocate wireless spectrum, and they typically look to the ITU, which is affiliated with the United Nations, to say what technologies qualify. WiMax will now be one of their choices when faced with a requirement for 3G, which the ITU calls IMT-2000.&quot;Having the ITU say that it counts really opens up some opportunities,&quot; said Peter Jarich of Current Analysis Inc. In particular, carriers that participate in upcoming auctions in Europe may choose WiMax instead of the more established 3G systems, he said. Broader deployments of WiMax in Europe, which has seen a few rollouts so far, would help increase production volumes and in turn lower equipment prices worldwide, according to Jarich.The ITU-R approval is a victory for advocates of technology neutrality, who want carriers to have more choices for high-speed wireless deployments, Jarich said. In most parts of the world, 3G is dominated by WCDMA, the next step on the migration path from GSM. But the ITU-R has also recognized CDMA-2000, the 3G upgrade to CDMA networks, and TD-SCDMA (Time Division-Synchronous Code-Division Multiple Access), developed in China, as well as other technologies.&quot;To have WiMax approved as an IMT-2000 technology is a huge win for the WiMax Forum,&quot; said Ron Resnick, president of the WiMax Forum, the industry group that certifies interoperability of products using the technology.What the standards body actually voted to support was OFDMA (Orthogonal Frequency-Division Multiplexing), which forms the basis of WiMax today but is also set to power future technologies, including LTE (Long-Term Evolution), a system now under development as the next step in the GSM migration path. Commercial LTE deployment is expected in 2009 or 2010.WiMax, based on the IEEE 802.16 standard, is designed to deliver IP data traffic at multiple megabits per second over a range of several kilometers. A fixed version is already certified by the WiMax Forum industry group, which plans to start certifying interoperability among mobile products next year. Sprint Nextel and Clearwire plan to deploy WiMax in markets across the U.S. starting late this year in what is set to be the biggest rollout yet.

(InfoWorld) - It's been a year since a Mobile WiMax service was launched in Seoul and one of the world's most wired cities became one of the most wireless. The service is based on WiBro, a South Korean system that has become a part of the 802.16e Mobile WiMax standard. Whereas Mobile WiMax encompasses three frequency bands and several signal bandwidths, WiBro covers a subset of these and is limited to 2.3GHz and an 8.75MHz bandwidth per channel. To mark the launch of its WiBro service last year, KT Corp., the former state-run telecom carrier, took journalists on a trip around Seoul to try out the service in a WiMax-equipped bus. The reporters came away impressed, able to watch Internet video streaming while surfing the Web and video conferencing all while driving down the street. But what's the reality a year later? Last week I returned to Seoul to test the service again, this time outside the controlled environment of a promotional bus ride. Seoul is among the first cities in the world to have Mobile WiMax, so the results provide an indication of what the rest of the world can look forward to in the future. I accessed the service while on the subway, in a bus, and sitting in a coffee shop, and the results were as impressive as they were in last year's staged demonstration. This was especially true on the subway. Riding the number 2 line from Samseong Station to City Hall, the journey has both underground and overground sections. It connects the Teheran Valley high-tech district in the south, crosses the Han River and ends in the heart of Seoul's business and media district. Throughout the 30-minute journey I did not lose the signal once, although the speed did fluctuate somewhat. It would often drop when the train moved out of a station and increase again when it arrived at the next stop. Web and e-mail access worked so well that I decided to try something a little more demanding and accessed streaming video news clips from the Yahoo Japan portal. The clips are encoded at 300k bps (bits per second) and played without any problem, even while the train was in motion. Equally surprising was that my little experiment did not draw the attention of the passengers sitting next to me. In a country where most high-end cell phones have TV reception, watching streaming video on the train doesn't seem to impress anybody! I also accessed an FTP site in the U.S. from the train and started to download a 40M-byte video file. The software indicated a download speed of up to 660k bps in stations, and about 320k bps when the train was in motion. Access from a bus produced much the same results, and while surfing from a coffee shop I enjoyed a connection that hit those same top speeds and remained stable. Technically the WiBro service appears a success, at least if the results of my small trial are anything to go by, so it's a surprise that it has attracted less than 10,000 users in its first year of service. The service costs a flat fee of 16,000 won (US$17.60) per month for unlimited use during the current trial period, and KT even throws in a WiBro adapter, which plugs into laptops via the USB port. So what's holding people back? Until now a limited number of WiBro adapters has been available. said Yeom Woojong, a spokesman for KT in Seoul. But now more companies are offering them, he said, and KT expects to attract more subscribers as the year goes on. At the start of the year it set a target to have 200,000 WiBro users by the end of 2007, and it's sticking to that number, Yeom said. Â

(InfoWorld) - Samsung Electronics this week will demonstrate a version of WiMax that can transport data at double the speed of current systems at theÂ 3GSM trade showÂ in Barcelona, Spain, it said Monday. The "Mobile WiMax Wave 2" system uses MIMO (multiple input multiple output) technology and smart antennas to realize speeds of around 34MbpsÂ downstream from the network to the user and about 8Mbps in the opposite direction, the company said in a statement. MIMO involves sending data using multiple antennas to increase the total data throughput. At those speeds it's possible to download an MP3 music file in about one second and a full CD of data in less than three minutes, said Samsung. A commercial service based on the technology on show in Barcelona isÂ planned by Sprint NextelÂ in the U.S. later this year. The carrier will use Mobile WiMax to supplement its 3G (third-generation) cellular service and plans to reach 100 million U.S. residents with the new network by the end of 2008. Before that service can be utilized terminals compatible with the network are needed. At 3GSM Samsung will also be showing a chip set compatible with the technology that can be integrated into devices. Competitors have also been showing similar chips recently. On Monday NXP Semiconductors and Israel's Runcom Technologies said they also plan to offer a chip set compatible with the Wave 2 system.
