China Mobile Hong Kong will released LTE TDD / FDD converged networking start TD-LTE commercial network at the end-of this year. Prior to this, China Mobile Hong Kong Company has announced the introduction of TD-LTE the existing FDD LTE network technology, TD-LTE and FDD LTE dual mode converged network construction in Hong Kong.
In June of this year in Hangzhou, China Mobile Hong Kong demonstrated the world’s first TD-LTE and FDD LTE in Hong Kong for roaming and demonstrated LTE TDD / FDD converged network technology. Expected that the end of this year, China Mobile Hong Kong Company will launch LTE TDD / FDD converged services in Hong Kong, which will be the first dual-mode LTE network in the Asia-Pacific region.
It is understood, the FDD (frequency division duplex) and TDD (Time Division Duplex) as the two different duplex mode, respectively, can be used the spectrum of the symmetric and asymmetric. The industry believes that, in the the 4G Internet age video streaming, interactive Web downstream position of absolute dominance, TDD high capacity, asymmetric advantages will gradually become apparent, especially in the increasingly tense situation FDD resources, to promote the integration of LTE TDD / FDD group The network will become an inevitable trend.
From a global perspective, LTE TDD / FDD converged networking has become an important global mobile broadband evolution direction. It is understood that the European Hi-3G in Sweden and Denmark, deployment and commercial TDD / FDD LTE converged networks; Japan’s Softbank has been the basis of commercial TD-LTE, FDD LTE commercial network was launched in the end of September this year, which converged networking operating ; European companies such as Vodafone and E-Plus have both TDD and FDD frequency and opened the fusion test network.
Currently, LTE TDD / FDD converged networking has achieved full integration of products from standard industry chain. Terminal manufacturer, the world’s leading system suppliers of Huawei, ZTE, Datang, Ericsson, Nokia Siemens, Alcatel-Lucent launched a common platform products TDD / FDD, Total chip manufacturers at home and abroad has also become common R&D direction.
It is understood that China Mobile has now completed the testing of TD-LTE scale test work and officially launched the 10+3 city to scale trial network construction work, the construction of 20,000 base stations will be completed this year and in mid-2013 Complete the expanding scale pilot test work.
