Telecom to place focus on CA technology

21 Sep 2015

Chinese full service provider China Telecom is planning to make carrier aggregation (CA) technology a core component of its network development plans, Mobile World Live writes, citing the director of wireless research at the China Telecom Research Institute, Sun Zhenqiang. The operator, the smallest of China’s three mobile network operators in terms of subscribers, will gradually roll out CA due to its advantages in handling data traffic. To date, the operator has launched commercial CA networks in 17 cities.

As previously noted by TeleGeography’s CommsUpdate, Telecom has set out plans for a three-layered network which would use frequencies in the 850MHz and 700MHz bands for wide coverage of basic voice and data service, whilst 1800MHz and 2100MHz spectrum would form the operator’s ‘gold capacity layer,’ handling the bulk of its traffic. Finally, a ‘hotspot layer’ – incorporating the operator’s 2600MHz time division LTE (TD-LTE) platform, as well as frequency division duplex LTE (FDD-LTE) technology – would provide additional capacity in high demand areas.
