Hi Jaskay. Thanks for the input on Market Share.
AND GOOD GRIEF.... I REALLY CONFUSED THINGS BY MENTIONING CELL-LOC WHEN I REALLY MEANT TO SAY WI-LAN.
I'm embarrased... Please reread that post and substitute
Wi-Lan, for Cell-Loc.
The technology that I was talking about (CSMA/CD ) is a means of keeping two stations (on a LAN) from transmitting data at the same time, and "blowing each other
out of the water" (IE causing a Collision).
I brought that up, as well as WECA, because according to
the Wired News article at wired.com
The WECA alliance is interested in making all products
all work together....
I would take that to mean that WECA Standards would not
allow these products to Collide with each other in the Air Interface.
In post # 544, I asked Mr. Hatim if W-OFDM products can
detect the presence of other carriers, from products
such as Bluetooth (which is primarily a connection scheme
for cell phones) ...
I also asked a W-OFCM product would adjust itself so as to avoid RF (Radio Frequency) interference... IE avoid blowing
others out of the water (colliding).
In his reply (post # 548, he indicated that W-OFDM listens for for a clear channel before transmitting. but that collisions can occur...
This would happen if the Bluetooth devices, etc. were not also designed to wait for a clear channel ...
or if any two devices happen to transmit at the same time, after waiting for a clear channel.
This is why I think that all manufacturers should be in
the WECA alliance and should agree on a Carrier-Sensing,
and Collision Avoidance scheme, such as CSMA/CD.
( I think) this collision avoidance scheme would be
in addition to any parameters that may be specified in the 811 specifications.
Best regards,
Mardy.
