The problem with all of this discussion is that it's irrelevant to the real world application. For instance, a home application is completely different than a commercial application. The home application is generally based on one access point of entry into the system. The commercial application may, depending on the needs, be more than one access point. With the home application a standard would be developed for say a certain range as a maximum. There is no guarantee that you will receive a signal at the same distance that I receive in my house. The cell provider is not going to tweak your system so you can get coverage everywhere you would like. You either get a signal using the pre-determined parameters or you don't. The home system would be designed en mass with a theoretical maximum.
The commercial system is designed from the ground up and a very specific set of parameters are most likely used to determine access throughout the entire coverage area. The patent does not require a one case fits all scenario. In other words, in the commercial application a scenario might involve 10 access points to cover the area. Within this coverage area you are determining the parameters as you set up the system. Unlike a home situation a commercial situation might have a need for persons within the building structure to all have access to wifi in order to do their job. In a home situation you can move around your home until you obtain coverage or add a range extender.
In a real world, there is a maximum allowed by the FCC part 15 and any signal put out there is allowed to transmit up to or less than this allowed maximum.

I don't see any part of the description talking about improving signal strength. I can assume that if my range is extended my signal strength will also be improved. To what degree, I don't care as long as I get a signal laying on my couch. And by adding this extender you have modified the system, so your theoretical maximum has just increased.
In my opinion, what people are trying to do is say the patent is like a shoe size and one size fits all. In reality the patent is not defined as such and that is what Tmob is trying to do. You need a bigger foot print buy more access points. You know from your real world analysis whether you get coverage at a certain location within your environment. Tmob is trying to say the patent switching is dependent on being at a certain distance from the access point and that doesn't change from system to system. Nobody designs a system to meet the requirements of all situations. They make more than one shoe size don't they? The patent was designed to be flexible and anytime you can switch from wifi to gsm you are infringing the patent because you will be within that defined maximum.
Calypso's attorneys are arguing.
" There is no indication that the system must measure the maximum distance between the wireless device and the computer facility; the wireless device must simply be inside or outside the predetermined distance. "
My info. And this is a distance that is known when the system was set up using whatever equipment was used. The patent isn't concerned with measuring anything, which is the beauty of the patent.
