Abstract
Methods and apparatuses for managing coexistence of multiple wireless devices that share a radio frequency band and communicate with a wireless network device. The wireless devices include both wireless personal area network (WPAN) and wireless local area network (WLAN) devices. The wireless network device monitors data activity for WPAN devices to determine whether the WPAN devices are active or inactive, and sets one or more polling intervals for the WPAN devices accordingly. The wireless network device consolidates polling for multiple WPAN devices into a common WPAN polling time period and sends a radio frequency (RF) reservation request to a WLAN access point (AP), the RF reservation request including an indication of a duration for the common WPAN polling time period, during which the multiple WPAN devices are polled. WLAN data packet transmission is delayed during the common WPAN polling time period to mitigate coexistence interference.
