DSP based OEM Radio Modem with Built-in wireless link Monitoring and Management Tools:
The AW400 radio modem provides a high-speed Point-to-Point and AW software (AWareTM) supports user selectable modulation techniques (GMSK, 4FSK, DBPSK, DQPSK, D8PSK, or D16QAM), which allows the user to achieve the highest data speed for a given range (up to 11 miles/18 km). It also includes a selectable error correction, which improves the functioning of the radio modem under interference.
The unmatched features of AW400 include data scrambling, frequency hopping, user selectable transmit output power level, low power consumption sleep modes, autoscanning for base and plug-and-play installation for remote terminals.
AW400 supports two separate Application Data and Maintenance modes of single RS232 serial port.
The built-in software tools provide the wireless link testing, units’ status and error statistics monitoring as well as units’ settings change over the air. The firmware of the AW400 radio modem resides in a flash memory. The updating of the radio modem programs is entirely software-based. The flash memory is re-programmable through an RS232 interface or over the air.
