The move could create blanket urban wi-fi coverage, and allow the fixed-line operator to compete at least partially with mobile phone operators in offering internet services on the go.

At present most people mainly use wi-fi to connect their laptop computers to the internet, without wires, in their homes or offices.
Is this the future of extensive distributed wi-fi?
