Interesting in a patent assigned to Tmob in May 2012 they reference the 923 as prior art and include the following info :

"These IP-based networks, which may operate over unlicensed spectrums, may include short-range communications networks, relying on short range wireless communications protocols such as Wi-Fi, Bluetooth, and so on. The ranges of these networks may vary from network to network, but are often less than 500 meters (e.g., less than 200 meters). "

So why did they get a patent that deals with wifi/cell systems after the 923 was issued ? Isn't this the language Tmob was trying to eliminate in the Markman? They don't want any information related to a range. Aren't they trying to limit the 923 to a specific distance when it says otherwise? JMHO & questions.
