State-of-the-art narrow band radio modems

CAMPBELL, Calif., July 11, 2005 — ArWest Communications Corporation (ArWestà¢â€ž-), a privately held telecommunications company of Campbell, California, announces the launch of its AlphaWave (AW) range of narrow-band radio modems and associated management software AWareà¢â€ž-. These high-performance radio modems are designed for the Supervisory Control And Data Acquisition (SCADA) market where robustness and reliability are paramount. The AW400à¢â€ž- has been approved by the relevant statutory bodies – FCC, CE and CCC – for operation within their geographic regions.

These radio modems are now available for delivery in with a list price of $1,290; further details of the product can be found at the ArWest website

ArWest designers have applied advanced technology components and implemented the most unique, cost effective and expandable DSP based narrow-band software intensive (“Soft”) radio modem. The distinctive Plug-and-Play design provides self tuning and calibration, maximum performance, unmatched long distance coverage and robust enough to withstand the harshest environmental and other adverse conditions.

The ArWest radio modem provides a high-speed Point-to-Point and Point-to-Multipoint wireless data transfer at up to 38.4 kbps. AWare software supports user selectable modulation techniques (DBPSK, DQPSK, 8DPSK, 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 forward error correction, which improves the functioning of the radio modem under interference, multipath and other intense environmental conditions. The unmatched features of ArWest 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.

The AW product provides two separate Application Data and Maintenance RS-232 serial ports. Without changing the hardware, the radio parameter settings can be modified through the serial port from a PC.

Built-in software tools provide wireless link testing, testing of unit status, error statistics monitoring and all unit settings can be changed over the air. The firmware of the AW radio modem resides in flash memory. Updating of the radio modem programs is entirely software-based and the flash memory is re-programmable through an RS-232 interface or over the air.

The ArWest Alpha-Wave family products are manufactured based on their reliability, security, manageability, scalability and future expandability without any hardware change. The Alpha-Wave can be installed practically anywhere in the world-with the lowest possible cost of ownership.
