Question

Suppose there are two ISPs providing WiFi access in a particularcafe, with each ISP operating its own AP and having its own IPaddress block. a. Further suppose that by accident, each ISP has configuredits AP to operate over channel 11. Will the 802.11 protocolcompletely break down in this situation? Discuss what happens whentwo stations, each associated with a different ISP, attempt totransmit at the same time. b. Now, supposed that one AP operates over channel 1 and theother over channel 11. How do your answers change? a. Further suppose that by accident, each ISP has configuredits AP to operate over channel 11. Will the 802.11 protocolcompletely break down in this situation?

How do your answers change?

Explanation / Answer

//Hope this will helpyou. 1. If two access points work on same frequency band, then signal ofone AP will interfere with other AP. So the Bandwidth of both will decrease by factor 2. Bandwidth(new) = Bandwidth(Actual) / 2 for Each Accesspoint 2. In 2nd senerio, signal will not interfere to each other, so bothcan take benifit of maximum bandwidth.
