The Digi XBee SX 868 operates in the 863–870 MHz band and runs either Digi’s proprietary DigiMesh® or a point-to-multipoint networking protocol. The module is built around a low-power Silicon Labs microcontroller and an Analog Devices ADF7023 transceiver, with an integrated SAW filter for strong interference rejection.
Rather than a fixed duty cycle, the XBee SX 868 uses LBT + AFA — Listen Before Talk and Adaptive Frequency Agility. It samples the radio environment before transmitting and shifts to a different channel when it detects interference. The scan completes in microseconds, so it does not affect throughput. Digi documents an airtime budget of 100 seconds per hour per 200 kHz channel across up to 28 selectable channels, which scales the effective duty cycle with the number of channels enabled.
