TheWirelessWiegand Transceiver Kit is made up of two900MHz wireless components: WG900-PWireless GateReceiver, and the WG900-RWirelessWiegand Gate Transmitter.The kit provides a seamless, point-to-point or point-tomultipointwireless transmission using 900MHz technology.The WG900-P and WG900-R communicate back and forthwirelessly using a standard asynchronous serial datastream. Installations are quicker, easierand less costly.Each module comes with built-in 256-bit AES encryption aswell as an AES algorithm that is FIPS-197 certified. It utilizesa channel hopping scheme, making it virtually impossible to decipher
