NSN's Enhances Flexi Zone Controller for Small Cells

Nokia Solutions and Networks is extending its Flexi Zone comtroller, which runss on macro cells, to now support nearby small cells.

A software version of its Flexi Zone controller that can be deployed on Flexi Multiradio 10 Base Stations to implement clusters of outdoor and indoor small cells for fill-in coverage near existing macro sites, for example in streets flanked by high-rise buildings. It also enables early deployment of hot zones by re-using macro site infrastructure.


Flexi Zone controller software can also be used to increase the capacity of macro-cellular Distributed Antenna Systems (DAS) in large buildings by supporting the deployment of complementary LTE and Wi-Fi small cells. Unlike conventional DAS or hybrid DAS systems, the enhanced Flexi Zone controller can make use of many different transport media including a building’s existing and shared Ethernet (LAN), fiber or coaxial cabling, or even wireless links for large open indoor spaces, slashing operators’ deployment costs by avoiding the need to install dedicated connections. Using a mix of fiber and dedicated Ethernet, Hybrid DASs are a more recent variant of DAS that takes advantage of remote radio heads deployed closer to the antennas.

A third major development enables the Flexi Zone controller to support the integration of NSN Radio Application Cloud Server functionality to enable Liquid Applications on a cluster of small cells. Radio Application Cloud Server provides processing and storage, together with the ability to collect real-time network data.

“Flexi Zone architecture continues to push the boundaries of what small cells can do and future HetNets will look like,” said Randy Cox, head of Small Cells product management at NSN. “Our latest enhancements open up vast new potential for operators to provide top-quality mobile broadband services to their subscribers in even the largest indoor environments and make Flexi Zone the most versatile and lowest overall cost small cell solution. The ability to run Liquid Applications from clusters of small cells will transform what HetNets can do by providing game-changing applications and personalized services matched to a subscriber’s location and context.”
