Product Description

GD-G1162 is a digital radio modem whichsupports GMSK based communication protocol.With channel spacing of 12.5KHz, over-the-air data rate of 8000 or 9600 bps are supported. With channel spacing of 25KHz, over-the-air data rate of 16000 or19200 bps are supported.

The radio modem works as a half-duplex transceiver, meaning it can both transmit and receive data, however not simultaneously. The GD-G1162 provides a cost-effective solution for companies seeking simplicity, compactness, and reliability.They are well made, engineered for dependability and low in cost in order to minimize asset management expenses.
