Shanghai to become smart

Shanghai is on course to become a smart city by boasting the country's highest number of 3G network cellphone users and the most concentrated wireless signal coverage, among other key indicators that define a digital hub.

Those are the key findings of Smart City Shanghai Development Report, released by Xinhua News Agency last week.

The city is now home to 6.3 million 3G users under three different networks, 2.2 times the number in 2010, the report said.
