摘要： Mutual interference experienced between co-located WLAN and BT devices is minimized. An improved wireless local area network (WLAN) scheme using fragmentation, that itself mitigates BLUETOOTH™—related interference, without relying on a presumed cooperation from co-located BLUETOOTH devices. The use of fragmentation in a WLAN network allows a longer concatenated period of WLAN activity, with corrupted segments being retried. Therefore, the chances of getting a full frame transferred during the repetitive interference by BT voice is greatly improved. A coexistence scheme is provided that is active in the MAC layer of a Wireless LAN (WLAN) device, aiming to make optimal use of the non-occupied BT slots for both uplink and downlink WLAN communication. The co-existence scheme improves throughput performance for active co-located WLAN and BT devices. Because the coexistence scheme is link-based instead of global and is enabled only when required, frame loss and fragmentation are minimized, leading to less network overhead.
