OREANDA-NEWS. At the 5G Tokyo Bay Summit 2015 held at the DOCOMO R&D Center in Yokosuka, Kanagawa, Huawei and NTT DOCOMO, INC. performed a live demonstration of the co-channel coexistence between Licensed-Assisted Access (LAA) and Wi-Fi systems with Small Cell.

Huawei and NTT DoCoMo successfully demonstrate LAA and Wi-Fi co-existence key technology.

During this demonstration, LAA operated on a 5GHz unlicensed band. The results indicated that with the assistance of a key co-existing technology named Listen-Before-Talk (LBT), LAA is able to co-exist adequately with a neighboring Wi-Fi system, while maintaining most of the performance advantages of LTE.

This live demo represents the latest successful joint field trial by Huawei and DOCOMO deploying LAA, which first began in early 2014. Huawei and DOCOMO will continue their close collaboration on this technology in terms of joint testing as well as in their efforts to standardize LAA with the 3rd Generation Partnership Project (3GPP).
