How much would weather have an impact on something like this? http://www.cisco.com/en/US/products/ps5861/products_data_sheet09186a00802252e1.html I've not actually used them, however, but I do like the radios (802.11g, same as whats in the 1200 units I do have) and they are outdoor mountable. This is 802.11g 54mbps gear. I'm pretty sure you can configure the root bridge to choose a channel based on local interference, but I'm not sure if it will change channels if it needs to. There is a command to ask what the interference is on all channels, too, however. (dot11 dot11Radio 0 carrier busy, and then show dot11 carrier busy) Output looks like this: Frequency Carrier Busy % --------- -------------- 2412 1 2417 10 2422 23 2427 5 2432 12 2437 18 2442 16 2447 8 2452 2 2457 3 2462 4 The integrated antenna should 'just work' for across the street. The injectors for these units use an interesting dual-coaxial (75ohm F-connector, even !?!!?) design that also brings ethernet to the unit. You can ground at the unit and the entry point and the injector includes lightning protection to protect the inside gear and power infrastructure. My guess, for a bridge, is that you can just setup wpa-psk with a long key for security. Looks like $850 per unit with power injector (AIR-BR1310G-A-K9-R). They have a kit for doing the mounting and outdoor stuff, but the equipment is mostly standard except for the mounting equipment, so you'll need one of these too.
