[Shenzhen, China, May 23, 2012]: Huawei, a Leading global information and communications technology (ICT) solutions provider, recently unveiled eRelay, the industry’s first LTE TDD wireless backhaul solution to meet small cell transmission challenges, at the Cellular Telecommunications Industry Association’s (CTIA) Wireless 2012 event held in New Orleans from May 8 to 10. Huawei’s eRelay solution effectively eases constraints on transmission resources when small cells are deployed.
Operators worldwide have begun deploying small cells in hotspot areas to enhance overall network capacity in the face of explosive growth of mobile broadband network traffic. Many small cell deployments in these hotspot areas, however, are hampered by a lack of transmission resources; and such is commonly the case with available optical fiber. Operators all over the world are now focused on meeting these transmission and flexible deployment challenges facing small cells.
Huawei’s formulation of the eRelay solution was based on the analysis of micro base station deployments. It utilizes SingleRAN’s unified hardware platform, advanced LTE technology, 256 high-order QAM (Quadrature Amplitude Modulation) and MIMO (Multiple-Input Multiple-Output) technology, and provides wider bandwidth and greater transmission capacity. A more cost-efficient solution that works the same way as microwave transmissions, the Huawei eRelay solution uses NLOS (Non-Line of Sight) transmission and supports PtMP (Point-to-Multipoint) transmission.
Deng Taihua, President of Huawei LTE TDD&WiMAX&TDS Wireless Networks, said, "As the best business partner for operators, Huawei is dedicated to providing customer-centric solutions to help operators deal with the challenges of mobile broadband era. eRelay solves problems associated with transmission constraints, promotes small cell deployment ,improves capacity for hotspot areas and ultimately improves user experience."
