Wireless Utopia

The journey towards a free wireless world.

The OFDM Maharaja

Saturday, May 20, 2006

Its becoming apperent that Qulacomm is going to aggressively pursue the Flarion OFDM patents. The latest warning is from ABI Research which does not expect QC to let it go easily. And with QC paying up more for the patents of Flarion, there is no reason why it would not enforce them. Maybe SOMA networks did do a very wise thing after all when it licensed QC's OFDM patents. It forced them to future proof their solution to convince the carriers to adopt WiMAX.

But then the applications of OFDM encompass more than WiMAX. It is the 4G technology that all carriers and wireless infrastructure vendors are looking at. Its in the roadmap for both EVDO and UMTS. With DSP gaining more and more processing power and the cost of hardware decreasing, it would be feasible to put processing intensive slicon on to the subscribers terminals. There are lots of if's and but's and many technical hurdles along the way but then there is no viable contender to OFDM in sight as well!

So given all the patents in QC's stable, its future from the royalties is quite secured.
