Nokia Siemens Networks introduced a Liquid Radio-based “6 pipes” remote radio head promising 80% more capacity, 40% more coverage for TD-LTE compared to traditional 3-sector site designs.
Nokia Siemens Networks’ 6 pipes remote radio head, which is based on the company’s Liquid Radio architecture, leverages a unique 6 pipes beamforming feature that mitigates signal loss due to interference. The company said this is the first implementation of a 6-sector TD-LTE site.
Instead of deploying additional cell sites to handle increased subscriber density, mobile operators can use 6 pipes beamforming to reduce signal loss caused by interference. This yields higher throughput and lower latency, and thus significant capacity and coverage gains.
Nokia Siemens Networks also claims its pipe concept offers a cost-effective, future-proof alternative to the current ‘path’-based approaches, allowing more flexible allocation of sectors, carriers and transmit and receive channels by a base station. It can do multiple configurations, starting with a simple, low-cost, 3-sector site configuration and scaling to a high-capacity, 6-sector site configuration, when needed. Further, a simple software upgrade offers a smooth evolution path to LTE-Advanced.
“Our new, high-capacity 6 pipes remote radio head is a great addition to our TD-LTE RAN (Radio Access Network) portfolio and promises to take the TD-LTE experience to the next level,�? said Tommi Uitto, head of the LTE radio access business line at Nokia Siemens Networks. “In addition to enabling a more flexible approach to TD-LTE, the new product delivers much higher throughput and lower latency than other offerings, to enable higher data speeds. Subscribers can thus enjoy the same level of mobile broadband, anywhere and everywhere, no matter what applications they’re using.�?http://www.nokiasiemensnetworks.com/
