We're looking to setup a point-to-point link between two buildings circa 1.5km apart. Optical, RF, whatever. This would be in the Detroit metro area (Southfield, actually) so snow is to be expected at least part of the year. License-free would be ideal. The devices, or at least the transcievers themselves if seperate, must be weatherproof/ruggedized for outdoor use (obviously). One endpoint will go on a one-story building, the other can either be placed inside our 10th floor suite (about 140' up) and go through a green-tinted glass window, or on the roof (250' up). 100mbps is ideal, although if it's significantly cheaper to drop to 10, that might be an option. I was thinking that 54mbit 802.11g might be a good price-performance mix, but I don't know of the other products available out there. Does anyone have experience with something like this? Should we try using WiFi and directional antennas, or is that insane? What sort of experience have you guys had with different vendors gear? Please reply offlist and I'll summarize my findings to the list afterward.
