Switched On: No new wires, one new caveat
Each week Ross Rubin contributes Switched On, a column about consumer technology. In the decade that WiFi has blanketed home networks across the United States, several technologies aimed at using existing wiring in the home have met with limited success. These have included MoCA (Multimedia over Coax, which has been adopted by some service providers for implementing multi-room DVRs) and HomePNA (originally for phone lines but later expanded to coax cable as well). At least three dueling standards have also sought to bring high-speed connectivity over electrical wiring. HomePlug, the most successful of these, has had several iterations. The latest – HomePlug AV – is rated at a theoretical throughput of 200 Mbits/sec. However, power line technologies have been held back by high prices and occasional interoperability problems. But a new approach seeks to be the one protocol to rule them all, operating over phone lines, power lines or coax. Dubbed G.hn, the ITU standard promises up to 1Gbps theoretical throughput, with real-world usage over electrical lines expected to reach between 250Mbps and 400Mbps. If that sounds appealing to you, you're not alone. Service providers like the idea of G.hn since it allows them more flexibility than previous efforts. In fact, they like it so much that -- despite G.hn's capacity -- they have insisted on quality of service standards that could limit or prevent consumers from installing it themselves after they buy adapters from retailers.
Verizon LTE: no roaming, even if you want to
Several companies are hopping on the LTE bandwagon, but it's turning out to be more isolating an experience than we hoped. According to PCMag, a Verizon spokesperson confirmed that its fourth-generation broadband network won't be compatible with other carriers in the US. As it turns out, Big Red and AT&T each own a separate block of 700MHz spectrum with only a fraction of overlap, leaving little room for phones on both networks to mingle with one another. There's not much hope for roaming on MetroPCS or LightSquared, either, as their waves of LTE run at 1700MHz and 1500MHz, respectively. This smattering of frequencies means it'll be near impossible to get roam on other companies' 4G networks nationally. What's worse, the ITU has approved twelve bands for LTE use around the world, so don't count on a wide selection of global devices -- and you thought sorting through international 3G was bad, didn't you? We're still a long way from learning our LTE roaming fate, but it appears the largest carrier in the US won't make the journey any easier on us.
UN: worldwide internet users hit two billion, cellphone subscriptions top five billion
The UN's International Telecommunication Union predicted last fall that the number of internet users worldwide would hit two billion by the end of 2010, and it's now issued its full report that confirms just that -- 2.08 billion, to be specific. As the ITU's Hamadoun Toure notes, that number represents a huge leap from the mere 250 million internet users that existed a decade ago, and it means that roughly one third of the world's population now has internet access of some sort -- of those, 555 million have a fixed broadband subscription, and 950 million have mobile broadband. Just as impressive as that (if not moreso), are the number of cellphone subscriptions worldwide, which has now crossed the five billion mark. That's up from 500 million at the beginning of the year 2000, although the agency notes that it's only accounted for "subscriptions," and not individual users. Any way you slice it, however, that's quite a record of growth for the first decade of the 21st century.
ITU capitulates, admits that the term '4G' could apply to LTE, WiMAX, and 'evolved 3G technologies'
Though it's standing firm on the definition of its original 4G specification -- IMT-Advanced -- which only WiMAX 2 and LTE-Advanced are currently capable of meeting, the ITU is easing off its earlier rhetoric, admitting that the term "4G" realistically could apply "to the forerunners of these technologies, LTE and WiMAX, and to other evolved 3G technologies providing a substantial level of improvement in performance and capabilities with respect to the initial third generation systems now deployed." The whole dust-up started when carriers around the world deploying LTE and WiMAX networks (ahem, Sprint and Verizon) were throwing the "4G" term around very, very loosely -- and to their credit, the networks are indisputably a generation beyond CDMA2000 and UMTS / HSPA, so if anything, we'd fault the ITU for leaving today's modern networks without a generation to call their own. The "evolved 3G technologies" verbiage in the ITU's statement would seemingly even leave room for T-Mobile USA's claim that its 21Mbps HSPA+ network constitutes 4G... so yeah, score one for marketing campaigns. Of course, none of these carriers had ever planned to bow to the ITU's recommendations anyway, so the ruling has little practical relevance -- just know that the true 4G speeds are still a few years off. [Thanks, Nate]
ITU lays down law: WiMAX 2, LTE-Advanced are 4G, everyone else is a buster
Fleshing out what constitutes a 3G versus a 4G wireless technology is like trying to objectively quantify whether Coke or Pepsi is the superior beverage -- but for what it's worth, the UN's ITU is widely recognized as the closest thing we have to a final word (on the Gs, that is, not the colas). They've just issued a press release stating that of six technologies nominated for IMT-Advanced (the formal name for 4G) certification, just two have emerged victorious: 802.16m WiMAX 2 -- also known as WirelessMAN-Advanced -- and LTE-Advanced. That would leave Sprint, Verizon, and everyone else currently deploying WiMAX and LTE technically false in advertising their latest-generation services as "4G," though with so many technologies crowding the 3G space, we can't necessarily blame them; heck, even EDGE and CDMA2000 without EV-DO technically qualify as 3G in the eyes of the ITU, so yeah, the situation is really just as muddled as ever. For what it's worth, neither 802.16m nor LTE-Advanced are live anywhere in the world -- and they aren't expected to be for some time -- so whether you like it or not, the UN says you're still living a 3G existence no matter where you're located. So close! Follow the break for the ITU's release.
Internet to boast more than 2 billion users by year's end
That's right, by the end of 2010, it is estimated that more than 2 billion people -- nearly 30 percent of the world's population -- will be using the internet. According to a report released by the International Telecommunication Union, 2010 alone will see an additional 226 million users log on. The report contains some far less encouraging data, however, such as the fact that it's now estimated that in 'developed' countries nearly 71 percent of the population is online, while in developing nations, just 21 percent is. The discrepancy is beginning to shrink somewhat, but is so massive that it's likely to be a factor for many years to come.
Support for universal micro-USB phone chargers grows with ITU approval
The entire wireless industry has been congealing around micro-USB as a universal charging standard for a while now, and we've taken yet another important step toward completely ridding the world of bizarre proprietary connectors (you know what we're talking about, Samsung) with ITU ratification this week. The UN-backed International Telecommunication Union isn't just making the move to make our lives a little less hellish, though -- it's also a strategic environmental move on a couple fronts, since universal chargers mean consumers will be able to hold on to a single charger over the life of several phones and modern chargers are far more power efficient than models that are even just a couple years old. The ITU move isn't binding or compulsory, but there's enough momentum behind micro-USB at this point that it's pretty much going to happen for any phone you'd ever consider buying going forward, and many of the big players have already hopped on the bandwagon. We won't lie, we won't miss the days of buying a $40 car charger that powers, like, two LG models. [Thanks, d0mth0ma5]
DS2 already concoting a G.hn-compatible chipset
Man, these guys are really on top of things. Just days after the International Telecommunications Union (ITU) ratified the G.hn home networking standard, DS2 has emerged to announce that it is already working to introduce a G.hn-compatible chipset as early as next year. When brought to market, the DSS9960 chipset will enable manufacturers to jump in and attempt to revive the obviously flagging powerline niche. Will interoperability be what finally turns this segment into a viable business model? We'll wait 'til the wireless HD fiasco gets sorted before attempting to answer that.
ITU ratifies G.hn as new global standard for HDTV home networking
CopperGate knew this day was coming when it snapped up HomePlug AV's powerline business, and now the ink has finally dried on a new global standard for HDTV home networking. The International Telecommunications Union (ITU) has ratified a standard that will be published under the G.hn banner and will serve to deliver "high quality multimedia over power, coaxial, phone and other home network wiring." Reportedly, the protocol will also bring "up to 20 times the throughout of existing wireless technologies and three times that of existing wired technologies." Moving forward, it's expected that the specifications will be used by chip manufacturers to "build transceivers that can be incorporated into set-top boxes, residential gateways, home computers, home audio systems, DVD players, TVs or any other device that may be connected to the network." Sounds good -- now let's get some gear to take advantage. CES, maybe? It's a date.
LTE, WiMAX vie for ITU's love and affection
The International Telecommunication Union's wireless division is getting ready to seal the deal on formal approval of its own official standard for 4G communication, officially dubbed IMT-Advanced, and the usual suspects are in the running to take the top prize. The folks behind LTE are submitting a modified version, LTE-Advanced (get it? because the ITU standard is IMT-Advanced!), while the WiMAX camp will come storming in with 802.16m. Pundits are looking at the standardization process as a clutch opportunity for the two to make nice and combine into a unified 4G force, but considering their relatively divergent development paths thus far, it seems like a pretty remote possibility -- not to mention the metal-on-metal clashing of corporate egos that'd undoubtedly tie things up into oblivion.

CopperGate buys HomePlug AV Powerline business
Let's face it -- HomePlug AV has had a pretty rough go of it, and while we wouldn't consider the technology dead just yet, we can't imagine it ever rising to prominence at this point. Our negativity isn't stopping one CopperGate Communications from following its heart, however, as it just announced this week that it would be taking the business off of Conexant Systems' hands. The pickup makes CopperGate the "the first semiconductor company with home networking technologies supporting all three wire types (coax, phone and power lines)." The deal gives the new owner "all relevant power line technology and silicon products, related patents, appropriate licenses, and requisite personnel," which sounds to us like everything including the kitchen sink. Of course, there's no way of knowing what kind of impact the acquisition will have, but CopperGate's hoping that it will "better prepare the company for the new ITU home networking standard, G.hn."

WiMAX now officially part of the 3G standard
We remember when WiMAX was just a twinkle in a wireless engineer's eye, and now it's all ready for the big time, as the ITU officially approved the spec as part of the 3G standard today. That's doubly special since WiMAX is the first non-cellular tech to get approval as 3G, but with services like Sprint's Xohm blurring the line for consumers, we can see how it's easier to just lump it all together. Of course, Sprint confusingly says Xohm is "4G," but it looks like they may need to tone it down now that the ITU has spoken. Either way, the ITU's decisions usually get enacted by governments, which means carriers with 3G spectrum will soon be able to start building out WiMAX networks without additional regulations. It's so bittersweet when they grow up, isn't it?[Via PhoneScoop]
IEEE pushing 802.16m WiMAX to 1Gbps, hopes to converge with 4G
If there's one thing that we'll never be satisfied with, it's finding out just how many nanoseconds we can shave off our download times from year to year, and thankfully, the IEEE seems to get that. While it has certainly taken its sweet time with 802.11n, the task force has already voted to make 100G the next Ethernet speed, and now it's pushing to make WiMAX implementations even quicker. Reportedly announced at 3GSM, the IEEE has began working on a new version of the 802.16 standard, dubbed 802.16m, which "could push data transfer speeds up to 1Gbps while maintaining backwards compatibility with existing WiMAX radios." Potentially more interesting than cheering for speed boosts is the group's outright assurance that this protocol will meet the ITU's requirements for 4G, insinuating that it should be the token choice for further 4G developments. Nevertheless, the increased bandwidth is supposedly needed due to convergence between VoIP and various forms of multimedia (IPTV, streaming video, digital downloads, etc.), and however true that may be, some skeptics are still understandably doubting the whole "backwards compatibility" aspect. Still, the IEEE hopes to have this together by "the end of 2009," but considering the team's less-than-stellar track record in the deadline department, we're not holding our collective breath.[Via DailyWireless]
Researchers show 100Mbps cellular data
As usual, we're given virtually no time to revel in the high-speed (relatively speaking, of course) wireless data we do have before some eggheads have to go and throw the wet blanket on us. Researchers from Germany's Heinrich-Hertz-Institut (a division of Fraunhofer) have apparently taken some standard-issue UMTS equipment and modified it to use MIMO -- the same tech employed in many modern WiFi devices -- to achieve 100Mbps downstream and a full 50Mbps upstream. For the sake of comparison, UMB (aka EV-DO rev. C) takes the crown with 280Mbps down; while there's no word on when this MIMO stuff might hit the streets, UMB won't see the light of day until 2009 at the earliest, so our German friends have a little time to capitalize. And yes, we'll be just fine with a mere 100Mbps on our cellphones, thankyouverymuch.
SmarTone-Vodafone gets Toshiba TX80, TS32
The goodness coming out of Hong Kong's ITU Telecom World 2006 continues, and this time it's Toshiba flaunting the hardware. Their new TX80 and TS32 are both destined for Hong Kong's own SmarTone-Vodafone, and Toshiba seems pretty confident about the launches -- the senior VP of its mobile group even went so far to say that these are "just the phones that people in Hong Kong want and need." We're a little skeptical about the claim, though, seeing how the TS32 doesn't even do 3G, instead topping out with EDGE on the 900, 1800, and 1900MHz bands. Other features include a 1.3 megapixel cam, microSD slot, and Bluetooth in the buyer's choice of Lunar Graphite, Desert Gold, and Midnight Purple. The TX80 is the more exciting of the pair, bringing 3G data, dedicated music controls, and a more respectable 3.2 megapixel shooter. Both should be available now across Hong Kong, though we don't envision much of a rush for either phone. Sorry, Toshiba![Via I4U News]
Samsung shows bright i718 Pocket PC
Oh, you thought that when we said "bright," we meant "smart?" We suppose it could be that, too -- but more than anything, the Samsung i718's orange shell is just "bright." The fresh Pocket PC introduced at ITU Telecom World this week does the whole smartphone gig with a little more style than your average Windows Mobile device, though the specs aren't exactly earth shattering; would-be buyers can look forward to a 2.8-inch QVGA display, 2 megapixel shooter, 128MB of ROM, 64MB of RAM, microSD expansion, and Bluetooth 2.0. Though the phone's China-bound with no plans for a global release, the quad-band GSM / EDGE radio (somewhat unusual for a Chinese market device) means that North American readers pining for an orange PDA phone may have met their match.[Via SlashGear]
LG's KC1 Windows Mobile-powered smartphone to hit Korea with WiMax
While LG's Chocolate assortment is growing with feature-packed additions at an alarming rate, there looks to be a WinMo-powered sugar daddy headed down the pike with WiMax ready to rock. We knew Samsung and LG were using this year's ITU Telecom World conference as a launching plugging point for a few snazzy announcements, but today brings about the unveiling of a Windows Mobile 5-packin' smartphone boasting LG's Chocolate touch, built-in WiMax, a 2.8-inch QVGA touchscreen, two-megapixel camera, microSD slot, and Bluetooth. The phone will reportedly also support CDMA and EV-DO, and should be released in South Korea real soon -- unfortunately, there's "no word" on whether this beauty will ever see the light of day on American soil, but one can hope.[Via Slashphone]
Mobile WiMAX, HSUPA get spotlight at ITU Telecom World
LG and Samsung are using Hong Kong's ITU Telecom World 2006 as a platform for highlighting a couple technologies that, frankly, can't get here soon enough. It seems somehow appropriate that the Korean crosstown rivals are fighting for their share of the spotlight, parading HSUPA and Mobile WiMAX equipment -- both of which have the potential to shatter upstream speeds offered by the latest live technologies (HSDPA and EV-DO rev. A), while Mobile WiMAX also offers the tantalizing opportunity to pull upwards of 10Mbps down to you. While this isn't the first time we've seen either of these technologies in the wild, they're obviously becoming more ubiquitous at each and every trade show around the globe -- which means our dream of some day hosting Engadget Mobile on a cellphone grows ever closer.Read - LGRead - Samsung
