Huawei has launched what it describes as the industry’s first LTE TDD wireless backhaul solution, ‘eRelay’, which is designed to address small cell transmission challenges, and ease constraints on transmission resources when small cells are deployed.
The company observed that in response to the explosive growth of mobile broadband network traffic, operators worldwide have begun to deploy small cells in hotspot areas to enhance overall network capacity. Many of the small cell deployments in these hotspot areas are hampered by a lack of transmission resources. Operators globally are now focused on meeting these transmission demands and addressing the flexible deployment challenges facing small cells.
Huawei’s formulation of the eRelay solution is 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, providing wider bandwidth and greater transmission capacity.
Working in the same way as microwave transmissions, Huawei said eRelay is a cost-efficient solution that uses NLOS (Non-Line of Sight) transmission, and is also able to support PtMP (Point-to-Multipoint) transmission.
Deng Taihua, President of Huawei LTE TDD & WiMAX & TDS Wireless Networks, said: ‘As a key business partner for operators across the globe, Huawei is dedicated to providing customer-centric solutions to support them in managing the challenges they face in this mobile broadband era. eRelay is a cost-effective and efficient solution to problems associated with transmission constraints, while promoting small cell deployment and improving capacity for hotspot areas, which ultimately improves our user experience.’
