AW135

VHF 138 MHz to 174 MHz

DSP based OEM Radio Modem with Built-in wireless link Monitoring and Management Tools:

  • 48 miles Maximum Distance Range • Data Speed over the air 38400 bps at 25 kHz and 19200 bps at 12.5 kHz
  • Programmable Output Power (320 mW to 35 W)
  • Advanced Forward Error Correction (FEC)
  • RS232 serial interface with RTS/CTS flow control support
  • Data Speed over the serial port 9600 to 115200 bps
  • Testing, monitoring and control of the unit over the air
  • AlphaWave SuperScan® - automatic search and select for best frequency/channel

The AW400 radio modem provides a high-speed Point-to-Point and Point-to-Multipoint wireless data transfer at up to 38.4 kbps. 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 48 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, autoscanning for base and plug-and-play installation for remote terminals.

AW 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 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 RS232 interface or over the air.
