Birth of a Standard
The FCC appears to be crystal clear about radio’s in general, they have an approved range in which devices must operate in order to be legal—of course this applies to big operators but look at ham radio operators as well—they need a license. To drive an automobile you need a license and you need to demonstrate that you know the “rules of the road”. Somehow the court is saying that 110 is ok since tmobile is saying “I can’t drive 55”. Comical yes, but reality dictates that ericsson’s patent is an incomplete solution that suggests that time honored standards should be trashed and devices should no longer have to comply with FCC required operational range regulations.
Of course the industry would love this but the FCC would never allow it for the industry—for one thing people’s brains would get fried. For another it would propose a huge vulnerability to national security. Air travel would also necessarily become disrupted.
Hence all switches occur within a pre-established vicinity range period. As far as the FCC is concerned doesn’t matter where (for the most part), as long as it’s happening within that range. Hence we have the doctrine of equivalents lock stock and barrel.
One additional point, about the so called quality control parameter, it’s as if this is some kind of special voodoo apparatus that dramatically varies between cellular and wifi. My intuition says otherwise, wifi and short range protocols in general are going to be subject to tremendous noise variation as compared to longer range systems—meaning the ratio’s denominator is going to be all over the place—it’s going to vary much more than the actual bit rate signal strength so this ratio is going to vary more than the quality control for the long range cellular signal. Hence that variation will cause the quality control by comparison to cellular to be less and still hold the call. How can that happen? By law it can only happen with in the pre-defined vicinity range. Hence seamless switching does not depend on quality control at all and only exclusively on the pre-established vicinity range.
I really can’t make it any simpler than that.
None of what I have said is prolix, all very simple--cut and dry.
I for the life of me can’t imagine why calypso didn’t object to a mechanical engineer being appointed by the court.
