IEEE 802.16m standard will be ready by midyear
THE IEEE has announced that it will finalise the 802.16m standard in mid-2010.
This will make the technology the first international 4G standard even if operators are not as enthusiastic as one might have expected.
US-based Clearwire has said it is in no hurry to adopt the 802.16m standard and it will get around to it one of these days. The Russian based WiMAX operator Yota, however, said it is dead keen and is currently working with Samsung Electronics to roll out 802.16m networks.
More than 50 companies have committed to the development of 802.16m technology, which has been languishing on the drawing board at the IEEE since 1999.
The specification enables 120Mbps downlink and 60Mbps uplink using 4x2 MIMO (Multiple-Input Multiple-Output) antennas on a 20MHz-wide channel. This is double what current WiMax technology can manage even in the labs.
Clearwire said it will not even bother testing the technology until next year. It thinks it is unlikly to see a fully working 802.16m network until 2012, just in time for the world to end. µ

While reading some of the comments on this article I've seen some serious discrepancies about IEEE 802.16m and I have to say that some people really don;t know what they are talking about. First of all, IEEE 802.16m is a 4G technology since it satisfies and even surpass IMT-advanced requirements set by ITU-R. It is capable of a peak DL data rate in excess of 1Gbps for low mobility : 802.16m supports spectral efficiencies of up to 15 bits/s/hz with 4x4 MIMO and bandwidths of up to 100 MHz through band aggregation so do the math. Both LTE-A and mobile WiMAX 802.16m are competing for 4G standardisation but it seems LTE-A is winning.
"a 2 to 1 ratio 60Mbit/s upload useless", "4G standards require 1Gbit/sec while stationary.".
Welcome to the spoiled generation. You're going to get angry if you don't get real-time 3D ultra-HD porn to your phone in the middle of the Sahara next? Standards are made by engineers based on best technology estimates for the near future (and company policies).
If they could get more speed reliably, they would.
Then you'd get pissed that your phone isn't 8k*4k, because you don't seem to grasp how f***ing GREAT and MIND-BOGGLING what you already have is.
120mb/s (even minus 50% overhead) get you any piece of info you can dream of (rule 34 applies), essentially instantly, anywhere you feel like within a massive radius from a tower.
Be grateful, idiots!
"The specification enables 120Mbps downlink and 60Mbps uplink using 4x2 MIMO (Multiple-Input Multiple-Output) antennas on a 20MHz-wide channel."
who cares about some lame ass 2 to 1 ratio 60Mbit/s upload today, your cheap arse 11N can manage that at a real 1 to 1 ratio today.
the only thing going for both Wimax and the Greedy shareholders LTE is long reach but your average users cant buy, setup and use this long reach Wimax/lte router kit anyway.
OC if the Wimax chip vendors had'nt pissed the time to market up so badly and even looked at and actualy started MAKING AVAILABLE Wimax SOHO routers for the common man in the street to use then they might have had some cashflow to put back into Wimax2 etc...
if people wat to use or set a crappy ratio, they should just do that in Software using a virtual pipe over a real 1:1 ratio 1 to many wireless link.
4G standards require 1Gbit/sec while stationary. 802.16m doesn't meet the ITU's requirements for a 4G network.
LTE isn't considered 4G and it is 3x faster than 802.16m (up to 326Mbit/sec). LTE networks however can be upgraded easily to LTE-Advanced.
LTE-Advanced is considered 4G, but the standard hasn't been completed.
Well WiMAX can handle 10MHz channel BW with no problems outside the lab already, at this point I do not see any real 802.16m deployment happening soon as LTE is just around the corner and a lot of operators that did not jump into the WiMAX bandwagon are waiting for LTE. Probably those operators with WiMAX Networks will jump to WiMAX 2 if the hardware allows this and/if they have the spectrum available.
