This XBee S2C is an RF module designed for wireless communication or data exchange and it works on ZigBee mesh communication protocols that sit on top of IEEE 802.15.4 PHY. The module provides wireless connectivity to end-point devices in any ZigBee mesh networks including devices from other vendors. Please note that XBee is a module designed by ‘DiGi’ and ZigBee is the name of the protocol followed by XBee modules for establishing wireless communication. With a few of these modules, the user can set up their own ZigBee network up-and-running in a matter of minutes. The XBee RF Module is compatible with other units that use ZigBee technology. These include other XBee modules, ConnectPortS gateways, XBee and XBee-PRO Adapters, XBee Sensors and other products that are designated with “ZB” product name.
