  • Method of indicating packet bandwidth in a wireless OFDM network with multiple overlapped frequency bands
    Patent number: 9609092
    Abstract: A wireless OFDM transceiver uses a method of utilizing subcarrier characteristics, such as phase and amplitude, to indicate the bandwidth of a transmitted packet. By using different subcarrier characteristics in the long training symbols of a packet at the transmitter, the packet is associated with different bandwidths. The different bandwidths are used in a wireless network where devices can communicate using different frequency bands that overlap one another and where one is wider than the other.
