Product Description

GDWV23 is a wireless transceiver data module with small size, low power consumption, stability and reliability. It has a frequency between 223 and 235 MHz frequency and is widely used as a remote unit, making it ideal for monitoring and controlling smart grids.

The GDWV23 features a narrowband, low power wireless data transceiver VHF wireless data transmitter. A special advantage of the VHF band is its wide coverage, ultra-long-range communication capability and the same carrier power and antenna gain, and can be polled daily on a single radio channel with the fastest transmission /reception turnaround time in its class, or report hundreds of thousands of meters.
