ABSTRACT:
Methods, devices and systems for WLAN communication are described. Intercell interference between overlapping WLAN cells is mitigated by a combination of frequency reuse, code division and time resource negotiation. Information used for time resource negotiation can be broadcast via beacon signal or communicated via a wireline backbone system which interconnects access points.
