A wireless LAN uses polling to provide communications between 15 workstations and a central base station. The system uses a channel operating at 2.5Gbps. All stations are 200 meters from the base station. Polling messages are 64 bytes long and frames are of constant length of 1250 bytes. Assume that stations indicate that they have no frames to transmit with a 64-byte message. Assume that the signal propagates at a speed of 3*108 m/sec.
