WiMAX-Certified (trademark term by the WiMAX Forum) products will begin to appear on the market in very early 2005. The first "plugfest" tests begin the end of this November and will open up testing to any vendor showing up with products to test. The band "profiles" first being tested will be 3.5GHz and 5.8GHz.
As for EU's approval of 5.4GHz, it has already been opened and products are already available from multiple vendors, including us. It should also be noted that the WiMAX Forum has said it will only produce unlicensed versions of WiMAX-Certified (tm) products in 5.8GHz. Maybe that will change over time (I think it should change), but for now, there will be no WiMAX-Certified 5.4GHz. Kind regards, Patrick Leary Assistant VP, Marketing Alvarion, Inc. Exec. Comm.

Hi, the WiMaxCost(that is my personally name for WiMax:-) ) is stil on the "early" development.The first acceptable products will be on the market from 1-3years(depend on your volet:-) ). To me (becouse I'm from EU) is "the most promising technology":-) 802.11h (before called European Hyperlan) the standard is 802.11h and the band range 5470-5725MHz (255MHz extra space:-) ).That mean 12? non everlaping channels(Wi-Fi have only 3) and the fact that the draft(http://www.ero.dk/D697CBE5-5527-48C5-A6F6-9342C611D4AD.W5Doc?frames=0) is describing 1W e.i.r.p. for the outdoor(that mean around 5-12miles).Of course the 802.11h cannot be compared with the robust WiMaxCost,but anyway the upper 5GHz band is a natural step from the noise Wi-Fi to the longer and in fact faster distance for a acceptable price(price to be define:-),but is promising:-) ).The 5470-5725MHz will be available as I know until end of the year(in EU).
