Patent ID: 7463583

Claim:
A Wireless LAN system (WLAN) comprising: a sending station programmed to send WLAN communications; a receiving station programmed to receive WLAN communications from, at least said sending station; said sending station programmed to send said WLAN communications using an adaptive rate algorithm, said adaptive rate algorithm having a searching mode for searching for a data transmission rate mode that provides successful WLAN communication between said sending station and said receiving station; said adaptive rate algorithm having a transmission mode wherein said data transmission rate mode remains the same until a predetermined number of unsuccessful communication attempts occur, wherein when in said transmission mode, said data transmission rate mode is increased to a new data transmission rate mode equal to ((a current data transmission rate mode number)+((a total number of possible data transmission rate modes)−(the current data transmission rate mode number)) / 2) when a threshold number (TH) of successful data frame transmissions are concurrently made.
