Think about it... if every cell phone could transmit around the world it would be like every car in the world driving down the same street at the same time. It cannot work. Same with WiFi. Everybody's signal would be interfering with everyone else's if all receivers could hear all transmitters. the whole reason that radio technologies such as WiFi, Bluetooth and cellular telephones can work is that the have low power transmitters and a very short range.

Azulstar.com has made the attempt in several metro areas however they have been "challenged" with service issues. I have conducted a few Wi=Fi networking experiments & have only been able to establish a 4 mile area without some serious external antenna modification on the mobile devices although, it kind of defeats the purpose of the device.
