Briefly define the goodput of a wireless network and the concepts behind this factor.

What will be an ideal response?

As you read about the many speeds listed for 802.11, you need to appreciate that wireless networking has a tremendous amount of overhead and latency. WAPs send out almost continuous streams of packets that do nothing more than advertise their existence or maintain connections. Wireless devices may sometimes stall due to processing or timeouts. The end result is that only a percentage of the total throughput speed is actually achieved in real data bits getting to the applications that need them. The actual number of useful bits per second is called the goodput of the wireless network.
