802.20 for Wireless Broadband?

Jeremy Allaire points to Telepocalypse, suggesting that “unlike it’s sister standard 802.16 (WiMax), it is not limited to fixed line-of-site wireless, but can handle people moving in cells. It is less expensive to setup and operate than 3G, but more importantly is built entirely around an IP-based packet networking model, unlike 3G's CDMA based model which still retains a circuit-oriented, voice oriented architecture. The result may be that new wireless broadband carriers emerge where VoIP is a free service as part of their data offerings.”
