Tarana Wireless, introduced its AbsoluteAir product line today, which enables 3G/4G small cells to be deployed in both non-line of sight (NLoS) and line-of-sight (LoS) operation. Tarana says they have solved a complex backhaul problem that until now has hindered large-scale small cell rollouts with a low cost solution.
The AbsoluteAir product line consists of Concentrator Nodes (CNs), End Nodes (ENs), and an Element Management System (EMS). Operating in the sub-6GHz frequency bands (licensed and license free), the concentrator can apparently connect to up to 10 end nodes concurrently.
The Concentrating Multipoint is the hub, which can be mounted on a cell tower. The AbsoluteAir antenna has a 100 degree aperture that dynamically aligns during setup and operation, minimizing network planning and installation time. While a typical point-to-multipoint topology shares capacity among the links connected to a hub, Trarana says they can deliver a full 75 Mbps backhaul capacity to each small cell. It enables the number of links to scale as data demand grows, without degrading per-link capacity.
Each End Node connects directly via Ethernet to a small cell providing it with a full 75 Mbps dedicated backhaul capacity. Each link utilizes the same 10 MHz channel while maintaining full link capacity. Tarana claims nodes require just 15 minutes for installation and commissioning to full operation. The hub aggregates links for up to four ENs in a sector, providing 300 Mbps capacity in a single 10 MHz channel – with a spectral efficiency of 30 bits per second per hertz.
Tarana’s patent pending advanced signal processing algorithms are used to optimize link performance. Unlike existing NLoS products in the market today, AbsoluteAir is said to deliver 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. It supports licensed and lightly licensed TDD bands from 2.5-3.7 GHz for small cell deployments worldwide.
“Scaling small cell backhaul in terms of performance and density has been a significant hurdle for vendors but is an essential market need. In order to meet these challenges Tarana has created a new wireless paradigm with their CMP topology,” said Nick Marshall, principal analyst, ABI Research.
Tarana’s AbsoluteAir solution is being tested in multiple carrier trials in the U.S. and Europe beginning this quarter. The Company will showcase the products publicly for the first time at the 2013 Mobile World Congress, February 25-28 in Barcelona, Spain.
