ArWest Communications Corp. exceeds established standards within the SCADA and outdoor telemetry markets with the release of AlphaWave100Rx (AW100Rx) series DSP based integrated wireless modem, the first in a series of next generation Narrow-Band products. The AW100Rx radio modem provides a high-speed Point-to-Point and Point-to-Multipoint wireless data transfer at up to 38.4 kbps. AW software supports user selectable modulation techniques (BPSK, QPSK, 8PSK, or 16QAM), which allows the user to achieve the highest data speed for a given range (up to 50 miles). It also includes a selectable error correction, which improves the functioning of the radio modem under interference. The unmatched features of AW100Rx include data scrambling, frequency hopping, user selectable low power consumption sleep modes, and plug-and-play installation.

The built-in software tools provide wireless link testing, unit’s status and error statistics monitoring—as well as unit’s settings change over the air. The software of the AW radio modem resides in a flash memory. The updating of the radio modem programs is entirely software-based. The flash memory is reprogrammable through an serial interface.
