China Telecom has become the countryís second operator to launch 4G services, having activated its Time Division Long Term Evolution (TD-LTE) network in 100 cities late last week, South China Morning Post writes. The 4G service is currently only available via USB modems, although a compatible MiFi router is also available to support other devices. In terms of pricing, Telecomís offerings range in price from CNY70 (USD11.47) per month with 1GB of data, to CNY280 per month for 10GB. Meanwhile, China Unicom, the nationís second largest provider by subscribers, is expected to weigh-in next month with the launch of its own TD-LTE network. Both Telecom and Unicom intend to rely heavily on Frequency Division (FD)-LTE for their 4G networks, whilst China Mobile will use the home-grown TD technology exclusively. However, sector regulator the Ministry of Industry and Information Technology (MIT) has not yet signalled when it intends to make FD-LTE licences available.
