Anyfi Networks claims to make WiFi a 4G technology

A company called Anyfi Networks has a new technology that claims to be able to turn WiFi networks in a high-density urban environment into a 4G type of network. The way it is able to do this is simple and spooky at the same time.

The company has a technology that it calls WiFi over IP. Its tech takes the WiFi radio signals from devices like smartphones and routes it over an IP connection. The whole system would work like this. An ISP in a location where it has lots of customers would provide modems or routers with Anyfi tech inside.

As its subscribers go around town, their devices would automatically connect to their ISPs network by piggybacking onto the unused bandwidth of subscribers whose wireless networks are in range of the mobile device. Basically, you steal bandwidth from other subscribers as you meander around town. The company claims that the way it routes the data requests for the user's device even if one of the access points is controlled by a nefarious user, the bad guy can't access the user's device or data.
