Product Description

The GDWP1R is a 1.5 watt data wireless modem that provides long distance and powerful communication links that can carry a variety of traffic and is designed for data transmission and can support selected pre-emphasis, squelch and audio amplifier voice communications. 

1.5W output power wireless modem

Grand's data wireless modems have a UHF radio transceiver designed from the ground up as data radio modems.  At the same time, it has a good low frequency response in radio applications, making it a competitive choice for data applications at speeds from 1200 -19200 bps.
