Huawei Releases WTTx 2.0 Unlocking the Potential of the Wireless HBB Market

Nov 25, 2016

[Tokyo, Japan, November 25, 2016] Huawei today released its wireless HBB (Home Broadband) solution called WTTx 2.0 at the 2016 Global MBB Forum.

"Two years ago, Huawei was keen to release wireless to the x (WTTx), a comprehensive wireless home broadband (HBB) solution,” said Edward Deng, President of Wireless Solution, Huawei. “This solution is enabling a fast growing number of households to easily enjoy broadband access and is driving the use of digital applications as an integral and reliable component of our daily lives. WTTx features easy implementation, excellent cost efficiency, and has quickly gained huge popularity among global telecom operators as a preferred choice to provide broadband services for more than 30 million households worldwide. "

Huawei partners with operators to implement and conduct further research into WTTx, along the lines of classification as WTTX 1.0, 2.0, and 3.0 based on 4G and its evolution technologies 4.5G and 5G. WTTx 3.0 in the 5G era will provide HBB access rates higher than 10 Gbit/s.

Huawei’s WTTx 2.0 features significant improvements from the dimensions of broadband capability, network convergence, O&M, and service provision, upgrading WTTx 1.0 to WTTx 2.0. Huawei considers these dimensions as four forces propelling WTTx 2.0.

Force 1: advanced broadband capability

WTTx 2.0 provides a diverse range of innovative solutions including massive MIMO, achieving a more than five-fold increase in spectral efficiency, as well as a significant decrease in the cost-per-bit, and Gbps access rates. WTTx 2.0 helps operators deploy WTTx networks with lower E2E costs and higher rates for the provision of quality broadband services to additional households.

Force 2: seamless convergence

As for operators providing both mobile broadband (MBB) and WTTx services and those providing both fixed broadband (FBB) and WTTx services, WTTx 2.0 offers a seamless convergence solution. For example, diverse quality of service (QoS) solutions allow for resource sharing between MBB and WTTx services, achieving an optimal level of network experience. WTTx 2.0 provides a convergence billing system, which integrates WTTx and FBB service billing for operators who provide both services, achieving central service billing without network reconstruction.

WTTx 2.0 implements integrated design of V-Band backhaul and LTE base stations to successfully tackle operators' long awaited concerns about site backhaul, converging unlicensed and licensed spectrum resources. The free V-Band significantly reduces backhaul transmission costs, while attaining large capacity and a single-carrier backhaul bandwidth of up to 2 Gbit/s. The integrated design simplifies installation and maintenance, effectively alleviating challenges presented by site backhaul.

Force 3: efficient O&M

Operators must implement a range of systematic operation approaches from number allocation and household CPE deployment to CPE maintenance for the development of a new user, requiring procedural efficiency improvements. The WTTx Map of WTTx 2.0 helps operators accurately and visibly allocate numbers. WTTx 2.0 adopts cables typically reserved for power supply or satellite TVs and uses these cables to supply power for outdoor CPEs and transmit signals from outdoor to indoor locations, resolving the last-meter challenge of household CPE installation. The CPE management system is then used to help operators centrally and remotely supervise CPEs.

Force 4: support for diverse services

WTTx 2.0 delivers a diverse range of services, besides simple broadband access. For example, WTTx 2.0 supports IPTV services, facilitating the inheritance of the wired broadband service model. WTTx 2.0 also supports Smart Home, which indicates a transformation from the provision of digital to more smart home oriented services. CPEs can then be used to integrate V-Band broadband access for the expansion of indoor 4G coverage and deploy virtual private networks (VPNs) for small- and medium-sized enterprise network deployment.

By 2020, an additional 430 million households are expected to have broadband access, while broadband rates will be accelerated for 380 million households. The transformation from digital to smart home will be achieved in 168 million households across the globe. "4.5G networks have been widely deployed around the world, while operators are dedicated to deploying 4.5G-based WTTx 2.0 networks, boosting revenue growth and competitiveness." said Mr. Deng. "The newly released WTTx 2.0 will help operators further expand the boundaries of HBB and unlock the latent growth potential of the market."
