Not that I know of. I have all of the patent documents and some of the technical supporting documentation and don't see any prior art for the "switching" mechanism. When our patent was filed, the WiFi alliance had yet to even ratify the standard. Auto switching at the time was restricted to cellular and paging traffic and was very different than it is today and certainly not between separate technologies - which is why the patent speaks specifically about paging technology. We take it for granted that wireless infrastructure is so readily available and that almost everyone is carrying around a smart phone in the US that is capable of GPS, Bluetooth, Multiple wifi technologies and most also have multi-band cellular capabilities as well. This was not even remotely the case in 2000.
