Shippert The 802.11g standard includes a variety of data rates using different modulation schemes; lower data rates are able to carry for longer distances or cope with noisier airwaves. The modulation schemes G uses for rates of 11 Mbps and below are precisely those used for 802.11b. So although G offers much better data rates at short distances under good conditions, its long range performance is exactly the same as B. And, unless specifically excluded, B devices can interoperate with G devices and services. (A offers similar rate/range performance to G, but because of its higher frequency it uses more power to achieve that, and A gear is typically more expensive than G.) I believe the current record for a B signal, using directional antennas under optimal conditions, is about 25 miles. I routinely see usable signals at about 1000 feet.
