XBee 865/868MHz LP DigiMesh Module

The XBee 865/868LP RF modules provide long-range wireless connectivity over DigiMesh networks. The XBee 865/868LP is also the industry’s first RF module using 868MHz and surrounding frequencies for LBT + AFA (Listen Before Talk and Adaptive Frequency Agility). This virtually eliminates interference by listening to the radio environment before any transmission starts and automatically shifting to a new channel when interference is detected. This patent-pending frequency scan occurs automatically and in a matter of microseconds so as not to impact performance.
