Mobile carriers, tech firms building world's fastest cellphone network

Guildford, Britain

ON the outskirts of this sleepy commuter town just south of London, plans are underway to build the fastest cellphone network in the world.

The work is being done at the University of Surrey, where a leafy campus is dotted with rundown brutalist-style buildings. Here, researchers and some of the world's biggest tech companies, including Samsung and Fujitsu, are collaborating to offer mobile Internet speeds more than 100 times faster than anything now available.
