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.

Jaskay, you are doing a great deal of DD & this is a good thing IMO. Thanks for sharing it with us. I read it all although some of it is hard for me to understand. It is very complex (wireless technology) and contains much uncertainty. However I try to keep things somewhat simple and look at the overall picture. I believe that Wi-LAN's technology is at this point superior and will likely remain superior as it develops. The applications for high speed data transmission are immeasurable. I feel speed & performance are huge assets and that will determine who succeeds. In the graphic arts industry where I work high speed data transmission is crutial. The files are huge and complex and the demands on turnaround time enormous. This is another probable market for WIN. I know so because they have performed demos for a few of my customers. WIN will by no means "control the world", but will achieve significant market share IMO. As for your comments in comparing VHS/beta and replacing technology later. I don't agree, look at cell phones, I've had about 6 and each has been superior to the previous. Look at computers, new one every 2-3 years. How about modem connections, I've had 14K, 56K & currently @home cable modem. WIN technology will be relatively low cost to purchase & install in the near future. People will pay for performance. Countless times I have seen my customers make large capital purchases of technology & then find it does not perform satisfactorily, so they dump it in less than a year & purchase something better. All JMHO of course. Cheers!!!

I do not want to really get involved in the discussion but will attempt to add some clarification. The 802.11 is a standard for devices that operate either in the 900MHz or the 2.4GHz bands. The 802.11a is intended for devices in the 5.xGHz bands. Compatibility is a non issue since they will not operate in the same band. Some companies are likely to introduce products that are based on 802.11a but operate in the 2.4GHz. However, at this stage, these will not be standard products. Hatim
