Clearwire: Just Say No

[Yournet@hotmail.com]

Clearwire's current products are not 802.16 based. They are NextNet (now 
part of Motorola) OFDM-256 FFT TDD based.  I would be leary of investint in 
a PCMCIA card because of performance issues and the fact that they will 
eventually shift to 802.16e-2005 (WiMAX universal mobile version) based 
system similar to that to be deployed by Sprint-Nextel next year.  None of 
Clearwire's current products will work or are upgradeable to WiMAX.  There 
will be at least two vendors who provide end use CPEs/SUs, USB dongles and 
PCMCIA cards that will work at both 2.3 GHz and 2.5 GHz  frequency bands 
used in the U.S., Korea, Singapore, Taiwan, and other regions as well as 
being able to operate (given roaming agreements of course) between other 
operators in 2.5 GHz band.
