Point to Multipoint millimetre wave wireless backhaul solution targets small cell networks
Operating in the 42 GHz band, the company’s millimetre wave PMP backhaul is better suited to meet the demand for increased network capacity than traditional backhaul approaches. It provides the 100 Mbps needed for LTE that copper cannot accommodate, avoids the expensive trenching of laying cable, and is much more economical than Point to Point (PTP) wireless backhaul..
A single Bluwan millimetre wave PMP transmission hub can connect 20 cell sites at 100 Mbps, offering 20 times more throughput than existing PMP microwave solutions. As it operates in the 42 GHz bands, spectrum is much more cost effective. It also avoids the increased spectrum congestion and limited channel sizes increasingly faced by PTP wireless backhaul in dense, urban areas using sub-40 GHz spectrum. In addition, millimetre wave PMP only uses one sectoral antenna to serve a cluster of mobile base stations from a transmission hub, meaning it requires less equipment on a mast. This all correlates to more efficient use of limited cell tower space, lower site rental and lower maintenance costs.
“With millimetre wave PMP backhaul, MNOs, wholesale providers and ISPs can easily distribute capacity to end points as required,” says Shayan Sanyal, Chief Commercial Officer at Bluwan. “Consumers will benefit from greater available bandwidth, better quality of service and more cost effective mobile broadband services. Our PMP architecture is also a modular solution that can scale with an operator’s requirements, enabling operators to ‘grow as they go’ and provision progressive capacity as cell density increases.”
The backhaul system is made up of three main components; the company’s patented Wireless Wave Division Multiplexer, the FTTA 42 GHz Backhaul Radio Unit, and an all outdoor compact NTE unit — comprising modem, multiplexer, radios and antennas in one box.
The FTTA Point to Multipoint (PMP) millimetre wave backhaul will be generally available from April 2012, and is already in trial with a number of customers.
