Hi Robert, Please see the 802.16 PDF file: grouper.ieee.org for an earlier, more pessimistic view of the rocks and trees. FYI most measurements point to a delay-spread variation of 4usec, not the 20usec in the paper. petere

What is starting to appear are systems designed to be compatible with what is expected for the final approved version of IEEE 802.16, WirelessMAN. From the looks of it, IoSpan, Wi-Lan, BeamReach, and probably Alvarion will have systems prior to the final acceptance. Wi-Lan, for instance, says that their system can be field programmed to comply with the spec once it passes. What will make BB wireless take off is the ability to do reasonable NLOS at low cost. What ill drive the cost down will be competition from the chip suppliers. Atheros, Intersil and a few others have participated in 802.16 meetings and at least a few can be expected to come out with parts. Interoperability plus volume sources for the chips will provide the critical pieces of the puzzle to make wireless broadband take off. I see this shaping up similar to 802.11 WLAN. Also in the works are chip sets that combine 802.11g, .11b or .11a with 802.16. Obviously there is difficulty combining standards for radios that operate at separate frequency bands but it is in the works.

Robert: I've spent the past 3 days reading everything I can get my hands on regarding Soma Networks. They have developed a WCDMA solution for MMDS spectrum that can deliver 12 MBS data, quality voice, and wireless cable. Gilder mentioned the company is his most recent report. The advantages of their technology is that it does not require line of sight mentioned in your article. Fixed wireless is a product waiting for real sponsorship. If wireless companies can figure out a way to deliver the MMDS spectrum from existing cell towers, the technology would quickly provide last mile solutions for residetial users.
