The Long Term Evolution (LTE) network will give super high speeds across the city and could mean the end of computers ever needing to be plugged into a wall for a connection to the net.

The so-called "fourth generation" system is being rolled out by Hong Kong mobile network operator CSL in partnership with telecoms equipment maker ZTE Corporation.

"The first launch of an LTE network any place in Asia is truly historic," Joseph O'Konek, CSL's chief executive, told AFP.

"For a lot of people, this will be their first experience of the Internet. They are at a huge advantage to previous Internet generations because they are leapfrogging all those fixed line technologies.

"It is truly going to unleash the power of human networks as this kind of system rolls out more and more across the world."

LTE enables faster data downloads and uploads on mobile devices compared with a third-generation network.
