Nokia Siemens Networks launches industry’s first TD-LTE ‘6 pipes’ remote radio head
Espoo, Finland – December 7, 2011
- Offers 80% more capacity, 40% more coverage to deliver cost-efficient TD-LTE
- Helps operators reduce site costs by up to one-third
Nokia Siemens Networks has introduced a Liquid Radio-based ‘6 pipes’ remote radio head* that uses the company’s unique pipe approach to offer unprecedented flexibility in delivering TD-LTE.
“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.”
By covering three sectors with a single radio head**, operators can reduce site costs by up to one-third. It is the first remote radio head that can support a 6-sector TD-LTE site to deliver 80% more capacity and 40% more coverage as compared to traditional 3-sector sites. This enables higher data speeds, and reduces total cost of ownership by 40%.
Nokia Siemens Networks’ 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.
Nokia Siemens Networks’ 6 pipes remote radio head is based on the company’s Liquid Radio*** architecture, which self-adapts coverage and capacity based on subscriber demand. The offering’s unique 6 pipes beamforming feature mitigates signal loss due to interference****. This helps deliver up to 50% higher data speeds and improved coverage, compared to 4 path radio heads, for subscribers in high-density areas, both indoors and outdoors. This feature also eliminates the need for additional sites, and reduces CAPEX, OPEX and site costs.
The offering is 3GPP standardized and is now commercially available globally.

Notes to editors:
*A remote radio head is the radio part of a base station that resides with the antenna and is distinct from the baseband unit part of the base station.
**Nokia Siemens Networks’ 6 pipes remote radio head can use a single radio head for three sectors, instead of the existing three radio heads set-up offered by competitors. Operators can thus use fewer radio heads and this, in turn, lowers CAPEX, OPEX and site costs.
***There is a natural ebb and flow of capacity demand on mobile networks as smartphone, tablet and other smart device users switch between applications at different times and locations. Part of Nokia Siemens Networks’ Liquid Net, Liquid Radio self-adapts its capacity and coverage accordingly.
Through baseband pooling, Liquid Radio repositions base station components to achieve extreme scalability. Liquid Radio also manages unified heterogeneous networks to optimize broadband access. Furthermore, active antenna technology creates more compact, simpler sites that support multiradio, multi-band and multi-technology access.

****Interference typically increases as subscribers increase, as well as when a subscriber nears the edge of the cellular site. Operators are therefore compelled to consider deploying additional sites. 6 pipes beamforming eliminates this need by reducing signal loss caused by interference to deliver higher throughput and lower latency, and thus significant capacity and coverage gains. These result in higher data speeds, and enable a seamless experience for subscribers indoors and outdoors.
