Description
Zigbee (built on IEEE 802.15.4) is a low-power mesh networking protocol on 2.4 GHz that occasionally appears in the bibliography as a comparison wireless modality for indoor sensing. Range is limited (10-100 m), but mesh routing extends coverage. Zigbee RSSI / LQI fingerprinting has been studied for indoor localization, mostly as historical baseline before BLE took over. Listed here mainly so that mentions resolve to a canonical entry; for the thesis Zigbee is not a deployment target.
