Coexistence of OFDM and DSSS/CCK stations in a WLAN |
摘要 |
A local area network is provided where OFDM stations and DSSS/CCK only stations coexist. Before transmitting, an OFDM station learns of the modulation capability of an intended receiving station. If the receiving station is only capable of DSSS/CCK modulation then the OFDM station transmits DSSS/CCK modulated data. If the receiving station is capable of OFDM modulation, then the OFDM station transmits OFDM modulated data thereby enabling efficient bandwidth usage.
