War without smoke - LTE, UMB, WiMAX...

"OFDMA TDD WMAN", the new name of a subset of WiMAX, was recommended by ITU-R as an IMT-2000 radio technology last week. It's a good news for WiMAX. Someone said: WiMax Gets ITU Standards Boost. Yes, it is. But, still a long way to go.

Let's take a look at how many candidate technologies we may have for the future:
LTE of 3GPP, UMB of 3GPP2, WiMAX, Mobile WiMAX/WiBro, IEEE802.20...

Ericsson said they abandoned WiMAX and would focus on LTE only, Qualcomm must be supporting UMB and they claimed they have many patents on OFDM/WiMAX, they also proposed IEEE802.20, Korea will continue working on the WiBro, even in the wired acccess area, there will be some Passive Optical Networks (PON) emerging in the future...

So who will win this war? Nobody knows, and it is impossible that one of them beats all others. I think some of them must be co-existing. But, the following answer should always be true: " It's something unpredictable but in the end USER's right. " (Lyrics of the Time of your life by Green Day) :-)
