Tarana Wireless, a start-up based in Santa Clara, California, is showcasing its new “AbsoluteAir” wireless backhaul solution for supporting small cell deployments in both non–line of sight (NLoS) and line–of–sight (LoS) operation.
Tarana features a unique Concentrating Multipoint (CMP) architecture that delivers a full 75 Mbps backhaul capacity to each small cell and enables the number of links to scale as data demand grows, without degrading per–link capacity. The AbsoluteAir product line consists of Concentrator Nodes (CNs), End Nodes (ENs), and an Element Management System (EMS). Each EN connects directly via Ethernet to a small cell providing it with a full 75 Mbps dedicated backhaul capacity. The CN aggregates links for up to four ENs providing 300 Mbps capacity in a single 10 MHz channel – delivering spectral efficiency of 30 bits per second per hertz. A CN may be co–located with a macro cell where direct access to high capacity connectivity to the carrier’s core network is readily available. By leveraging existing carrier sites for CN installations, significant ongoing operating cost benefits are realized.
Tarana leverages advanced signal processing algorithms to optimize link performance. The company says it is able to deliver the full data rate on every link even in dense small cell deployments at a range of 2–4km in NLoS, and practically unconstrained in LoS operation.
Each link utilizes the same 10 MHz channel while maintaining full link capacity. The company is supporting licensed and lightly licensed TDD bands from 2.5–3.7 GHz,
Tarana’s AbsoluteAir antenna has a 100° aperture that dynamically aligns, eliminating time–consuming alignment during both setup and ongoing operation. The company says this enables deployment of individual nodes in just 15 minutes.
“AbsoluteAir was designed to meet requests from global carriers for a cost effective backhaul solution that could be easily and quickly deployed anywhere and everywhere across a metro area, without compromising on performance or scalability. I am happy to report that recent urban network tests confirm that our target specifications have been achieved” said Sergiu Nedevschi, executive vice president, chief product officer, and co–founder, Tarana Wireless.
