  • Method access point device and peripheral for providing space diversity in a time division duplex wireless system
    Patent number: 6088337
    Abstract: A method, access point device and a plurality of peripheral devices provide for controlling a space diversity switch in a time division duplex system. The method includes: inputting data to a peripheral; generating a CRC.sub.1 in a peripheral; transmitting the data and the CRC.sub.1 ; receiving, by an access point device, the data with the CRC.sub.1 ; extracting CRC.sub.1 and generating CRC.sub.2 from received data; determining whether CRC.sub.1 and CRC.sub.2 are equal and where CRC.sub.1 and CRC.sub.2 are equal, failing to generate a repeat request; where CRC.sub.1 and CRC.sub.2 are unequal, generating a repeat request; determining whether a number of requests=N; where the number of requests.noteq.N, incrementing a counter and returning to receiving the data with the CRC.sub.1 ; and where the number of requests=N, resetting the counter, changing an antenna state and returning to receiving, by an access point device, the data with the CRC.sub.1.
