Personal Wireless Access Points and 3G Hubs

Private mobile WiFi hotspots, which allow wireless devices to connect to the Internet, are restricted.

Because London’s wireless system is likely to be strained during major events, speculation about this ban has focused on an attempt to reduce overall bandwidth use.
