  • 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.

  • 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.

  • 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.
