Soon there will be no where left to hide in London Town. The city is quickly becoming one giant WiFi hotspot, just as mayor Boris Johnson promised. Its iconic red phone boxes, the Thames, the Underground and even a minicab company have all been hooked up with free wireless. Now a plan has been approved to turn every famous black cab into a rolling 802.11 beacon. Company Eyetease has received approval from Transport for London to equip the vehicles with WiFi antennas that will provide 15 minutes of free high-speed data in exchange for sitting through a 15-second commercial. As the cabs ride through the city, the on board router will dynamically switch between 3G and 4G networks to maintain a constant connection. And, in an effort to get cab drivers hooked for the early 2013 launch, the CabWiFi service will provide special driver accounts that provide unlimited and commercial free service.
