Description
Overview
GAOTek ZigBee Module uses a narrowband embedded radio modem for the 434 MHz ISM band. Compact and designed for ease of use, it incorporates LoRa® technology to achieve extremely long range at low power, albeit at low bit rate. Its superior sensitivity allows the possibility of communication into areas once considered difficult for RF to penetrate using a dedicated command system with a simple to use proprietary protocol.
