Intended use for the device is industrial telemetry. The device performs as an IP router and has a single Ethernet port for network connection. The device examines the destination address of each information packet it sees on either the radio port or the Ethernet port and decides to ignore, respond to or forward the packet. The radio uses PSK modulation with a baseband symbol rate of 1 million symbols per second. To spread the power over frequency an 11 bit pseudo-random code is logical XOR’ed with each symbol. This gives an RF symbol rate of 11 million symbols per second. 11 chips per bit yields a theoretical processing gain of 10*Log(11/1) = 10.4dB. 11 Msps assuming rectangular baseband pulses would yield a bandwidth of approximately 22MHz. The RF section of the device consists of dual conversion super heterodyne transmitter and receiver sections with a PIN diode attenuator for transmit power control. The device runs on 12VDC provided by an external AC-DC power supply running at 110VAC and delivering 12VDC at up to 2.5A. The device is manufactured by Phihong as model # PSA-30U-120P. It is Grayhill’s intent to sell the device only through professional installers, however per 15.203 the antenna connector for the radio is a reverse polarity TNC style connector to ensure use of only approved antenna / cable assemblies. List of Tested Antenna Configurations 1) Maxrad 8dBi omni-directional antenna with 25 ft of Times Microwave LMR-400 coax with a loss of 1.8dB. As the radio transmits 350 mW or 25.4dBm the listed antenna’s gain of 8dBi brings ERP (neglecting coax loss) to 33.4dBm.
