With all these Assuming that Joel is thinking of using Aironet stuff, Cisco claims the following: 1 Mbps: -94 dBm 2 Mbps: -91dBm 5.5 Mbps: -89 dBm 11 Mbps: -85 dBm (source: http://www.cisco.com/warp/public/cc/pd/witc/ao350ap/prodlit/a350a_ds.htm) So, for a 20dB output radio, you've got a total link budget of 105dB to maintain 11 Megs. Add a fudge factor of at least 10dB and you've got 95dB of budget to deal with. Might work, might not - only one way to really tell :) Certainly no way for us armchair critics to tell with greater certainty from the data provided. -- andyw at pobox.com Andy Warner Voice: (612) 801-8549 Fax: (208) 575-5634
