Japan : NTT DOCOMO, HUAWEI's joint test demonstrates LTE's deployment over 5GHz unlicensed spectrum [TendersInfo (India)]


(TendersInfo (India) Via Acquire Media NewsEdge) According to NTT DOCOMO and Huawei, their joint test has demonstrated that LTE can be deployed over the 5GHz unlicensed spectrum. Presently, 5GHz unlicensed spectrum is used for wireless LAN networks in various countries.



DOCOMO and Huawei have carried out experiments of Licensed-Assisted Access (LAA), a technology that expands LTE-compatible spectrum to unlicensed spectrum bands, offering complementary access for the LTE operator network. LTEâ s compatible spectrum bands are at present licensed between the 700MHz and 2.5GHz bands in Japan.

According to the indoor test, LAA can work in 5GHz bandwidth, leading to cell capacity of around 1.6 times greater than that of IEEE 802.11n, a standard specification for WLAN. As per the results, LAA can be utilized as an enhancement of LTE and LTE-Advanced.


NTT DOCOMO serves nearly 63 million mobile customers in Japan, and further plans to launch LTE-Advanced by March 2015.

According to NTT DOCOMO, in dense traffic areas, higher-speed data communications and a higher cell capacity can be attained by using the 5GHz spectrum for LTE and LTE-Advanced on a complementary basis in coexistence with wireless LAN.

Seizo Onoe, executive vice president and chief technical officer at NTT DOCOMO, said, We aim to contribute to the standardization of this technology, which inherits the highly advanced features of LTE, to further enhance the global user experience with wireless broadband.
