I've actually got a couple applications with the extended distances. One of them I already have a 10mi link (75ft tower to mountain top). I am assuming that there are some other factors at work here as well since I had to go 70us to get a link at 5km to work. Based on that, I set the time-out for the 10mi link at 250us and it worked fine. The other applications are a little more specialized and the radios are at between 800m and 2km altitude above the surrounding terrain. In the application at 2km, where the 50mi distance is most needed, the radio is in motion. The 300m/us is the number that I was looking for. thank you

Peter or Anyone else, would you care to comment on this release? 300 Mbps seems like an odd-ball data rate. Does .11n suggest pedal to the metal? Maybe it's time for me to read up on 802.11n again. I thought it topped out at 108 Mbps. Or, is this about the product of 108 * 3 (consistent with the three radio-antenna combos discussed below), which would actually equal 324 Mbps minus bonding overhead? ------ Atheros Demos MIMO WLAN Solutions Atheros Communications unveiled its next-gen "XSPAN" family of MIMO (Multiple Input Multiple Output) wireless solutions capable of delivering 300 Mbps data rates across a home environment using a 3 x 3 transmitter/receiver architecture. The three-radio solution increases throughput and connection reliability at greater range. The Atheros AR6001 family of WLAN solutions is based on a highly compact, power-efficient, single and dual-band single-chip design. Atheros, which is a founding member of the Enhanced Wireless Consortium (EWC). said it is seeking to accelerate the next generation 802.11n WLAN technologies. atheros.com \| 05-Jan-06
