Patent ID: 7154854

Claim:
A method of wireless communication, comprising: transmitting a message to one or more wireless units, said message including (i) a first control data that causes said one or more wireless units to enable request to send (RTS) and clear to send (RTS/CTS) data transmissions in transmitting data packets to an access point, and (ii) a second control data that causes said one or more wireless units to automatically adjust a fragmentation threshold in response to changes within the wireless transmission medium based on a finite time duration for data packet transmission taking in account a size of each data packet and a data rate for transmission of each data packet; and measuring a transmission error factor and adjusting the fragmentation threshold in accordance with said measured transmission error factor by dividing a maximum fragmentation threshold by a divisional factor greater than or equal to one, the divisional factor being (i) decremented when the transmission error factor is greater than an upper threshold, (ii) incremented when the transmission error factor is less than a lower threshold and (ii) maintained constant when the transmission error factor is less than the upper threshold and greater than the lower threshold.
