Patent ID: 7418054

Claim:
A WLAN (Wireless Local Area Network) transmitter comprising: a transmission section configured to generate signals to be transmitted; and a control section connected to said transmission section to control said transmission section dependent on at least two transmission parameters, said control section comprising a state transition controller configured to step through a plurality of predefined control states, wherein said at least two transmission parameters comprise an RTS/CTS (Request to Send/Clear to Send) threshold value to be used for determining whether or not to activate an RTS/CTS mechanism, and at least one of said transmission parameter modification mechanisms is an RTS/CTS threshold adaptation mechanism, wherein said control section is configured to apply different transmission parameter modification mechanisms in different ones of the plurality of predefined control states, and wherein said state transition controller is configured to determine a respective next one of the plurality of predefined control states based on a value indicative of whether a transmission attempt has succeeded or failed.
