Very Important!
So it is 2008 and I am a subscriber to HotSpot@Home. I am outside walking my dog and talking on the phone over the regular over the air network. While I am still on the phone I walk in range of my home wifi and the call seamlessly handed over to my WiFi. Signal Strength and BitRate Error was NOT a factor in determining that switch, walking in to the vicinity of the already established range of my router, and having the right unique identifier enabled the auto-switch.
The point I am trying to make is that my phone will never auto-switch based on signal strength or bit rate error because I have no access to those access points. These UMA enabled phones are on Wi-Fi preferred, meaning that my calls will go through over the air networks until I walk into range of a Wi-Fi network that will accept my unique identifier. The Quality, Signal Strength, and Bit Rate Error, what ever they are does not have anything to do with the fact that my phone auto-switched to the network.
The only thing or things that have to do with the switch is the unique identifier and entering in the pre-established vicinity range relative to the computerized network.
So look how T-Mobile has us all fooled
They are hiding the GSM aspect of the switch and are deceiving us into believing that there is a computerized network everywhere and the phone switches from Wi-Fi to Wi-Fi all the time. Last time I check our patent covered GSM to Wifi technology. Wifi to Wifi would just be an extension to our base technology and still comes within the scope of the claims.
Once you leave your wifi network 99.99 percent of the chances are that you either do not have the unique identifier for the next wifi network or there is no wifi network, so you would auto-switch back again based on the phones code and exiting the pre-established vicinity range!!!
