IEEE approves next generation WiMAX standard, invites you to meet 802.16m
It's a term (and a technology) that has been bandied about for around four years now, but after waiting far too long for the next next best thing, the Institute of Electrical and Electronics Engineers has just given its oh-so-coveted stamp of approval to 802.16m. For those unfamiliar with such a term, that's the standard for next generation WiMAX, which may end up being capable of handling downstream rates of over 300Mbps. 'Course, those that were around during CEATEC last year know that Samsung already hit that in testing, but we're starting to feel as if that 1Gbps theoretical maximum that we were teased with in 2007 (and again last year) won't ever breach reality. It's tough to say what this approval means on the consumer front -- over the past four years, a tremendous amount of carriers have switched their allegiance to LTE, and even if WiMAX 2.0 finds itself ready for public consumption in the near future, it'll take a serious operator commitment before you'll ever enjoy the spoils. So Sprint, you feeling froggy?
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.

Samsung showing off 330Mbps WiMAX 2 mobile broadband over at CEATEC 2010
WiMAX 2, the sequel to the movie most people haven't watched, is back to tease and tantalize us courtesy of Samsung's new CEATEC demo. Filling four separate HDTVs with streaming Full HD and 3D content, the Korean manufacturer of everything electronic is touting its latest advance in mobile broadband connectivity that takes the top speed up to 330Mbps. That may only be a third of the theoretical max capability of WiMAX 2, but you know, we'll take it for now. The good news is that Samsung's innovation brew extends only to the conduits between WiMAX devices, meaning that your current-gen transceiver will be able to join the accelerated party as and when Samsung's ready to dish out the goods. With the 802.16m standard expected to be ratified by next month, Samsung projects its first commercial solutions will be landing in late 2011. Consider our calendars marked.
WiMAX 2 standard, and its theoretical 1Gbps downloads, to be finalized soon
While WiMAX isn't exactly streaming through the air everywhere at this point, domestically it has a solid head-start on LTE. Despite that, with many major players (like Verizon and AT&T) already choosing the latter of those two, WiMAX has a tough fight ahead of it for 4G supremacy. Maybe its successor will charm the competition, WiMAX 2 -- the artist formerly known as 802.16m. That standard will boast theoretical speeds of 1Gbps for downloads, though users are rather more likely to see something in the 100Mbps range (still a huge jump over what gets an Evo 4G user excited today). When can we expect all this bandwidth? The standard is due to be finalized in November, then hardware is expected to be ratified through 2011 before getting bolted to towers in 2012 where it will, thankfully, be fully compatible with O.G. WiMAX devices. Something good to look forward to, or too little too late to hold off the LTE hoards?
Intel, Motorola, Samsung and more join forces to support WiMAX 2
You probably have yet to experience its original incarnation, but with mere months left before the IEEE finally decides on the standard for the improved 802.16m version of WiMAX, a group of companies has finally stepped forward to support the new protocol, and solidify that nice, marketable "WiMAX 2" name while they're at it. Dubbed the WiMAX 2 Collaboration Initiative (or WCI for short), Alvarion, Beceem, GCT Semiconductor, Intel, Motorola, Samsung, Sequans, XRONet, ZTE and ITRI intend to, well, collaborate to make sure the new protocol can compete with LTE, while our old friends Sprint and Clearwire -- who are keeping their options open in the 4G wars -- simply cheer them on.

Clearwire in no rush to move to next-gen WiMAX Release 2
If consistently pulling down a fistful of megabits per second isn't causing the hair on the back of your neck to stand on end... well, first, we strongly recommend you get that looked at by a professional. Secondly, though, you might have a bit of a wait before you get another hair-raising boost in throughput, because Clearwire -- you know, the company that runs the WiMAX network shared by Clear and Sprint -- is looking to take a laid-back approach on the migration to WiMAX Release 2. The underlying standard, 802.16m, looks destined for IEEE approval some time this year with the promise of 120Mbps down and 60Mbps up in an effort to wage 4G war with LTE Advanced, but Clearwire's CTO is saying that he's not looking to trial the tech this year -- even though Russian carrier Yota is on track to make it happen using Samsung hardware. Instead, 2011 is a "much more likely" target for these guys, apparently, with commercial deployment plausible by '12. With the updated standard capable of speeds that put even high-end cable and fiber broadband connections to shame, you've got to wonder if backhaul isn't the real concern here -- or, even juicier, if they're not just trying to keep all the options on the table for a little while longer.
