| DSP Based Radio Modem with Built-in Wireless Link Monitoring and Management Tools: | |
|
|
| ArWest Communications Corp. exceeds established standards within the SCADA and outdoor telemetry markets with the release of AlphaWave series DSP based integrated wireless modem, the first in a series of next generation Narrow-Band products. The AW 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 (GMSK/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 AW include data scrambling, frequency hopping, user selectable transmit output power level, low power consumption sleep modes, auto-scanning for base and plug-and-play installation for remote terminals. AW supports two separate Application Data and Maintenance RS-232 serial ports. Without data link interruption the radio parameter settings can be changed through the unit’s Dedicated Maintenance 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 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 re-programmable through an RS-232 interface or over the air. |
