How is speed determined

How does the AP and end device know what speed to synchronize to? If the end device is transmitting at 60mW and the AP is 100mW who decides the conversation speed

Re: How is speed determined

AP controls the conversation .

Depending on the beacon lost , signal quality and strength AP decides

at what speed client can associate and can connect .

802.11b operates at 1, 2, 5.5, and 11 Mbps. The speed depends on the way the radio signal is transmitted. Higher speeds use more complex schemes, and reception of the higher speed signals requires a more sensitive receiver. If the signal is attenuated too much between the transmitter and the receiver, the receiver might not be able to understand the packet, and the two parties will have to use a lower speed.
