Hardware components
The ODU (Outdoor unit) is a self-contained transceiver unit that houses both radio and networking
electronics. Each radio supports operation as a PMP 450b SM or a PTP 450b BH (BHM/BHS). Note that
earlier versions of the 5 GHz 450b radios supported only one mode of operation either PMP 450b SM or
PTP 450b BH (BHM/BHS).
