The OFDM 60 Degree Sector Antenna Switch designed and developed based on RedLine AN-50 802.16 radio set to support high speed data link for Tactical Network Topology (TNT) experimentation series at Monterey Bay. There are three AN-50 radios connected to three 60 degree sector antennas for a combined 180 degrees of coverage within the bay. Each of theses antennas transmit and receive on the same frequency, which could have resulted in significant interference. The OFDM Sector Antenna Switch software was developed to resolve this issue. It allows monitor each AN-50 link status and maintain connectivity when a signal is established within its 60 degrees of coverage.
