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.
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.
