Abstract
Systems and methods are provided for implementing a coexistence coordinator in an access point (AP) operating in a Internet of Things (IoT) network. The coexistence coordinator coordinates transmission of both IoT-related data from an IoT radio and WiFi data from a WiFi radio, the IoT radio and the WiFi radio coexisting in the AP. The coexistence coordinator synchronizes time between the WiFi radio and the IoT radio so that times during which IoT-related data is to be sent from the IoT radio (in accordance with Time-Division Multiple Access (TDMA) channel access method) can be determined. Operation of the WiFi radio is suspended during those times when the IoT-related data is transmitted from the IoT radio.
