Wireless connection speed and thruput are quite different. The wireless may offer a connection speed of 54 Mbits/sec, but the actual thruput is considerably less, typically less than half. That's because of management packet overhead, [[wikipedia:IEEE 802.11|802.11b]] compatibility, inter-symbol gaps, and necessary timing delays. Also, note that wireless is [[wikipedia:Duplex (telecommunications)|half-duplex]], where only one radio in a given airspace can transmit at a time. | Wireless connection speed and thruput are quite different.
