For what application?

to control a robot

[Edited on August 26, 2005 at 6:37 PM. Reason : so has to be small and consume as little power as possible]

[Edited on August 26, 2005 at 6:55 PM. Reason : and if it has enough bandwidth to piggyback digital video on, that would be sweet as well]

Use a cellphone (seriously). Get something with unlimited in-network calling, and simply pair it with another of the same type and run your data line over that. You should be able to reliably stream commands, data, and even low framerate video.

Cells are already meant to operate long periods with low power consumption, it already has power filtering circuitry built in, and they're cheap. Easy to interface to your controlling computer too (just jack in a modem). Theroretically your usable range is unlimited.

Surplus equipment for just about everything you could need. The batteries especially are insane deals.
