Qualcomm's flash ofdm=w-ofdm+cdma?"Flarion has developed its own proprietary version of OFDM, called Flash-OFDM, which the company describes as a "fast-hopping" or spread-spectrum version of OFDM.
"We take OFDM and turn it into a spread-spectrum OFDM system," said Scott Corson, Flarion's director of product management. "This allows us to have the same frequency reuse capability as CDMA, which is 1 to 1, but it gives us three times the capacity of CDMA. This is a great benefit, but is actually not the reason we chose OFDM. We picked OFDM because it can send a single bit without any overhead.
"With CDMA, it is not cost-effective for a mobile unit to wake up, transmit a bit, and then shut up," Corson added. "You'd have to transmit something like 50 bits in order to make it cost-effective from an engineering tradeoff perspective. So, the ability we have to transmit a single bit gives a very high degree of control at the MAC layer. The result is that you can build error correction schemes with very fast round-trip times, giving us low latency and high reliability. This is the key to making the Internet experience mobile."

It seems to me that Qualcomm's flash ofdm is a hybrid of wi-lan's w-ofdm and cdma (cdma may also infringes wi-lan's MC-DSSS patent, as i understand). If so, what is left for flash-ofdm??
To make flash-ofdm relevant to wimax(802.16d/e), Qualcom has to prove that it is the original owner of w-ofdm and cdma, in my view.
The reality is: After cisco case no one can really chalenge wi-lan's IP, a basis of wi-fi and wimax technically.
what about cdma?
-what have been claimed in Flarion's patents on ofdm and cdma?
-when flarion was founded? After wi-lan's patents issued?
-When cdma was created? (1998?, wi-lan's MC-DSSS were issued in 1994 as i remembered)
