Hi Frank,
You wrote about a Flourishing Coexistence train getting derailed or going off the tracks, Message 23517333 I wrote it never left the station. It is still in the station, and although 802.16h Draft 2.0a is getting better, it is based on all stations following it's GPS-based schedule and control/status reporting.
With Respect to License-Exempt operation in the US, Part 15 requires that a station accept interference from all and cause interference to none (except experimentally licensed stations). In those bands, what does WiMAX offer that 802.11 radios do not?
Several years ago (June 2004?) the WiMAX forum chose to drop 5.8 GHz testing lower in the schedule of approvals, below 2.5 GHz.
The schedule for WiMAX 5 GHz testing is very uncertain because 802.16h is working to develop a standard for License-Exempt operation, and it presumably would be the basis for WiMAX testing.
802.11 outdoor revenue is not reported in the financial press, either because the companies are private, or because it is a small fraction of the company's reported revenue.
Six months ago, Atheros was shipping > 3M 802.11 chipsets a month, and their XR eXtended Range features were being used in 802.11-like OFDM outdoor radios. Now, none of the chipset vendors talk unit volume, and you must dig deeper to quantify the market and opportunity.
