WLAN and bluetooth harmonization
First Claim
1. A method for a collocated Wireless Local Area Network (WLAN) and Wireless Personal Area Network (WPAN) device to simultaneously communicate with a Wireless Personal Area Network (WPAN) device and a Wireless Local Area Network (WLAN), the method comprising:
- a) communicating with the WLAN using a WLAN interface;
b) communicating with the WPAN device using a WPAN interface;
c) using a RF antenna/front end system to communicate with the WPAN interface and the WLAN interface simultaneously;
d) receiving WLAN data packets and WPAN data packets simultaneously, wherein the WPAN data packets comprise WPAN data packets having WPAN data rates with a time gap between the WPAN data packets;
e) determining the size of the time gap between the WPAN data packets;
f) determining the WLAN data rate;
g) determining a WLAN data packet fragment size based on the time gap between WPAN data packets and the WLAN data rate; and
h) transmitting WLAN data packet fragments within the time gap between two consecutive WPAN data packets.

Abstract
Described is a WLAN/BT system with improved compatibility. It employs an adaptive algorithm that dynamically optimizes the WLAN data fragmentation size based on the current WLAN data rates such that the fragmented data packets fit the time slots allowed by the BT SCO stream gaps. The algorithm first uses system level information to acquire the concurrent BT traffic types to decide if TDM method needs to be enabled. Then it uses the smoothed WLAN date rate to calculate maximum fragmentation packet size consistent with current overall WLAN traffic.
