published an article about the developments in the mobile network standards. He heard from Dr. Albert Yeh, VP of OvisLink Corporation, that there's no future for WiMAX as we know it because cellular networks are developing at a much faster pace:
For instance, HSDPA (3.5G) standard today offers anywhere between 7.2 and 14.4 Mbps on cellphones, while future HSPA Evolution brings speeds of 28/11.5 Mbps, offering much higher upload bandwidth than WiMAX. But things get worse in next couple of years, when telecoms are scheduled to start implementing 3GPP LTE (Long Term Evolution). AirLive received a lot of questions from Telco operators in Europe and Asia about LTE devices in 2009 - and we’re talking about theoretical bandwidth of 100 Mbps down the airwaves and 50 Mbps up. If 3G LTE ends up at 50% of promised speed, there is a winner of mobile standard wars.
In the world of CDMA2000 standard, EVDO Rev.B features speeds of 14.7/4.9 Mbps for upload and download, while Rev.C is scheduled for next year. Verizon Wireless, Sprint, Nextel are all looking at EVDO Rev.C which should offer… you’ve guessed it right - 100 Mbps down, and 50 Mbps upstream.
