wonk - Have been lurking, trying to gain some insight into the WOFDM/VOFDM debate. With respect to the previous mobile questions, a few quick links, without comment -

I'm even less able than you to wade thru the IPR swamp. This is the MCDSSS patent re: the 3G/ITU application:
patents.ibm.com
and this is an old article that lends weight to Wi-LAN's OFDM claim -
edtn.com
Some knowledgeable sources have the same estimate of the CISCO matter as yours...some go further, and expect Cisco will try to trash Wi-LAN, while they do an end run.
It seems that knowledgeable supporters of Wi-LAN are more Euro-centric in their approach, and they feel that Cisco, in their experience, will be, well, Cisco.
This, of course, gets into the political dimensions of all this; I have heard the same remarks from the same sources re: Qualcomm.
Some have even suggested that Wi-LAN needs another "big gun" as an ally, and I'll leave you to figure out the names.
Again, I have a substantial investment in Wi-LAN, but I'm not trying to hype it on these boards - I'm hoping that knowledgeable posters will help establish the realities here.
For instance, I have a lot of informed opinion that says that the VOFDM system, as proposed, will be unreliable in bad weather, rain, snow, and temperature extremes. On the other hand, Bernard seems to feel that VOFDM can accomplish what it claims, and will overcome any multipath interference.
Another informed source says that the (future) Holy Grail is Software Radio, and that WOFDM and its algorithms are a natural, while VOFDM, being a hardware/software implementation, will be unlikely to succeed.
Anyway, the debate goes on, and we all eagerly await insight into these esoteric matters.
Best, Jim Kayne
