Abstract (en)

[origin: WO0213429A1] A unified communications protocol for wireless local area networks (WLANs) (400) which provides for the fair co-existence of the IEEE 802.11a ("11a") and HiPerLAN/2 ("HL2"), broadband communications standards. Wireless network devices (MTs) operating in accordance with 11a and HL2 may co-exist without interference by partitioning a 2 ms periodic time domain, based on the HL2 standard, into a first slice for use by 11a MTs and a slice for use by HL2 devices. An Arbitrator entity (ARB) broadcasts the time slices periodically at an interval which is greater than or equal to the periodic time domain. A first access Point (E-AP) handles communication with the E-MTs, and a second Access Point (M-AP) handles communications with the e-MTSs and the M-MTs. In this manner, convergence is provided between 11a and HL2, providing users with the best of both worlds, e.g., full interoperability, QoS and co-existence.
