THE 4G service, which is 20 to 50 times faster than the current 3G network, will cover more regions and bus routes in the city, the network operator China Mobile said yesterday.
The company had invited more than 1,300 people in Shanghai to try out its 4G network services. While many of them were happy with the high speed, they complained about the limited usage areas and poor data traffic.
China Mobile’s Shanghai unit had invited users to test its latest 4G products including MiFi routers, a portable device transferring signals to Wi-Fi, data cards and family-used routers based on TD-LTE (time division-long term evolution) technology, a domestic 4G technology.
It was part of the carrier’s large-scale national trials of 4G technology.
Shanghai Mobile’s 4G products provide download speeds of 10 to 15 megabytes per second, compared to one megabyte in the fastest 3G network.
But the 4G network coverage is limited now as it covers only downtown like People’s Square, Xujiahui and Nanjing Road and bus routes No. 49 and No. 926.
Shanghai Mobile said it will expand the 4G coverage to include the Bund and other areas and more bus routes. It has built 1,000 base stations — 700 outdoors and 300 indoors — to cover the Inner Ring areas. It will cover the entire city by yearend.
Handsets using TD-LTE are limited because the system is almost solely used in China. Popular smartphones like Apple’s iPhone 5 and Samsung Galaxy 4 don’t support TD-LTE.
