Wireless generations

Are you lost in the immense generational marketing hype surrounding wireless technologies? Robert Lesar, one of our top CCIEs, finally had enough and decided to classify various wireless technologies in terms that anyone can understand. The result: the “First-Mile WirelessIP Corner article.


  1. ok nice summary. But misses one, I think, crucial aspect of it all from a user perspective. 3G has issues with latency and HSPDA has issues with latency but much improved on its predecessor.

    afaik its to do with setting up the dedicated radio channels (and bearers).. This is trying to be solved by keeping the dedicated channels & bearers alive all the time to avoid the set-up time.

  2. and what about iBurst :-)
