NTT DOCOMO and Huawei have announced the successful demonstration of LTE transmission over the 5GHz unlicensed spectrum in a joint research effort. Based on the research, the 5GHz unlicensed spectrum which is widely used for wireless LAN networks can be used to extend the current LTE compatible spectrum bands between the 700MHz and 2.5GHz bands in Japan.
DOCOMO via its Beijing Communications Laboratories unit has been conducting joint research with Huawei at its facility in Beijing to expand LTE-compatible spectrum using the Licensed-Assisted Access (LAA) technique with the aim of increasing capacity in dense traffic areas.
The tests aim to utilizing the 5GHz spectrum for LTE and LTE-Advanced on a complementary basis in coexistence with wireless LAN.
"We are very pleased to have confirmed that LAA is a viable technology for LTE and future LTE-Advanced. 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."
- Seizo Onoe, Executive Vice President and Chief Technical Officer at NTT DOCOMO
"We are pleased to see successful joint field results on deploying LAA in partnership with NTT DOCOMO. Huawei is committed to helping operators to provide end-users with abundant mobile broadband experience by utilizing core LTE technologies such as LAA in spite of limited spectrum resources. We will continue to work with NTT DOCOMO and contribute to global standardization efforts through these joint research efforts."
- Ryan Ding, Executive Director of Board and President of Products & Solutions, Huawei
