Some Cisco devices support LRE "Long-Reach Ethernet", but I suspect that
500 meters is beyond even its limit, and it wouldn't be cheap.  We have a
few campus links that convert copper 100-BaseTX Ethernet to 100-BaseFX fiber
Ethernet and back again at the other end, and 500 meters is definitely
within that range.
  I believe the current record for 802.11_ wireless with directional
antennas and line of sight is about 25 miles.  That's probably your least
expensive option, although I'm not sure how much bandwidth you'll actually
get -- all of the standards fall back gracefully in steps to as low as 1
Mbps, although I'm not sure the downlink from the satellite is going to be
much more than that.
