Anyone know about the compatibility of high-voltage DC systems and 802.11b? The gear itself will be running on 120VAC via an inverter, but 600VDC/300A creates a strong EM field that messes with a lot of off-the-shelf RF gear and even some non-RF electronics.

The best wireless resource I know of is the part-15 list. Check it out at wisp@part-15.org Most 802.11b gear is not built to be very robust and tends to break down when high EMI is around. Personally, the gear is cheap enough that I would just give it a try.

To give you a vague idea, we had an issue with a 5 mile 802.11b run early on. It turns out that the signal was crossing a power line at less than 5 degrees. Cutting sharply across the power line fixed our problem. In general, it's best to just try it and see what happens. -Jack
I know of one installation that is just below (10 feet) a 50,000 watt fm transmitter in Portsmouth, NH. I don't think you'll have trouble. I'd be more worried about the automatic door openers and 2.4 GHz phones.
