Wireless technology co-existence
First Claim
1. A device incorporating a first wireless communications arrangement adapted to operate in accordance with a first communications standard and a second wireless communications arrangement adapted to operate in accordance with a second communications standard, at least a portion of a range of operation according to said first and second communications standards being in use in an overlapping relationship, said device having a protocol architecture including at least one of software implemented driver-level switching and dynamic parameter control adapted to ensure that there is substantially no mutual interference between communications at said device under either of said first and second communications standards.

Abstract
Multi-mode hardware that supports both Wireless LAN and Wireless PAN standards in the 2.4 Ghz ISM band are becoming available. This invention discloses a multi-standard wireless driver that includes a Multi-standard Wireless Adaptation Layer (M-WAL) with the capability to efficiently handle concurrent operation of multiple wireless transceivers while reducing mutual interference and matching application traffic requirements. The multi-standard Wireless Adaptation Layer is a virtual device driver that is not limited to networking applications but also takes other application profiles into account, such as those described in the Bluetooth standard.

16. A method of implementing co-existence of a plurality of wireless communications arrangements operating under communications standards having at least partially overlapping bandwidths, the method including implementing, in software at driver level in a protocol stack, a driver level switching arrangement adapted to ensure that there is substantially no mutual interference between communications under said communications standards.
-
17. A software product having encoded thereon executable code for implementing co-existence of a plurality of wireless communications arrangements operating under communications standards having at least partially overlapping bandwidths, the software product including code for implementing, at driver level in a protocol stack, a driver level switching arrangement adapted to ensure that there is substantially no mutual interference between communications under said communications standards.
