OREANDA-NEWS. March 18, 2015. Huawei announces the commercialization of its WTTx (wireless fiber to the X) solution based on LTE TDD technology at the 2015 Mobile World Congress in Barcelona.

WTTx, as is FTTx, is a broadband access solution using LTE TDD technology. As for WTTx, Huawei will commercialize 4*4MIMO (multiple input multiple output) and 2CC Carrier Aggregation to offer peak cell rates of over 400Mbps. Furthermore, with its multi-antenna technology and high gain CPE, WTTx offers a larger coverage radius, making the radius of 3.5GHz band comparable to that of 3G at 2.1GHz. WTTx also enables a wide range of services such as video broadcasting, VoIP, and VPN (virtual private network), enhancing an operator’s ARPU (average revenue per user).

WTTx features quick deployment and enables easy plug-and-play installation. For instance, an end user can purchase a CPE device at an operator’s business center, and access high speed internet simply by powering-up the device at home, making the buying experience quick and easy while reducing operational costs. By using an array of LTE-A technologies, WTTx reduces per-bit data cost, making the wireless broadband business much more profitable. The WTTx solution has now attracted interest for commercial deployment from fixed operators, mobile operators as well as from greenfield operators worldwide.

Huawei will provide Devices supporting both downlink 4*4MIMO and 2CC carrier aggregation in the second half of 2015 for over 400Mbps. Additional 4.5G technologies, such as downlink 8*8MIMO, 4-carrier aggregation as well as 256QAM (Quadrature Amplitude Modulation) will also be introduced to WTTx soon. This series of new technologies are expected to bring 250% spectrum efficiency gain, and provide a peak connecting rate of up to 1Gbps.

Mr. Veni Xiong, President of Huawei’s Wireless Network TDD Product Line commented that: "WTTx is the ideal complementary solution to provide fiber-like wireless connectivity in the fixed line out-reached areas. Huawei dedicates itself to building better connected broadband networks, allowing operators to achieve business success."
