Nokia Flexi Multiradio Antenna System
Taking base station performance to new heights
Product overview Active antenna technology is poised to bring a leap in base station site performance, providing higher capacity, lower site costs and a foundation for even greater gains in network performance. Nokia Flexi Multiradio Antenna System is turning these promises into reality. Nokia Networks is using its many years of experience of successful eld operations with its award-winning Flexi Multiradio Base Station platform to create an active antenna system that delivers the next generation of base station functionality. The development of active antenna systems is a major step forward in the evolution of base station sites, building on years of technological advances that have reduced radio network capital and running costs, while also providing ever greater capacity and coverage. Nokia Flexi Multiradio Antenna System enhances mobile network performance by integrating the base station’s radio frequency (RF) elements into the antenna. This is achieved by using 8 x 10 W power ampliers to feed the passive antenna elements. Not only does this bring huge cost and performance benets, but it also paves the way for advanced features such as fully adjustable electrical tilt per carrier or Radio Access Technology (RAT) and beamforming. A similar size to conventional passive antennas, Nokia Flexi Multiradio Antenna System oers much greater performance and brings major benets to operators.

Active antennas will support future sites Active antennas are the next logical step in building base station sites. Flexi Multiradio Antenna System provides an attractive alternative to Flexi RF Modules/RRHs, or it can be used in combination with these traditional Flexi RF units. It is clear that active antenna systems will bring about a stepchange in the evolution of radio networks and Nokia Networks is leading the way with its Flexi Multiradio Antenna System. Complementing our existing base station portfolio, the system will evolve to provide active support of various frequency bands, new radio systems and advanced technologies such as user-based beamforming.

Boosting capacity Flexi Multiradio Antenna System increases site capacity and coverage with advanced features like vertical beamforming, 2 x 2 Multiple Input Multiple Output (MIMO) and independent Tx and Rx electrical tilting per frequency or RAT. Up to 160% uplink and 70% downlink capacity gains and up to 30% coverage enhancement with beamforming compared to standard 3-sector feederless BTS. Future active antenna developments are expected to support multiple columns and horizontal beamforming, to further enhance the capacity.
Higher energy eciency and RF performance Moving the RF function inside the antenna means that no coaxial cabling is needed, avoiding components such as feeders and connectors. This reduces RF power losses signicantly compared to conventional base station sites, raising overall energy eciency to reduce electricity costs and carbon emissions for a much greener site.
Minimizing investments in the multiradio future As multiple radio standards become available, existing base station sites will need to be upgraded smoothly and quickly. Active antenna technology helps to protect base station site investments by providing multiradio capability to support GSM/ EDGE, WCDMA/HSPA, LTE and LTE-Advanced.
Ready for multi-band sites To meet the booming demand for mobile communications, a raft of new spectrum is becoming available worldwide. Nokia Flexi Multiradio Antenna System combines active and passive elements to also support traditional base stations on additional frequency bands. This protects an operator’s existing investments by eliminating the need to install additional antenna elements when deploying new bands. Future active antenna systems will also support multiple bands on their active elements.

Lower overall site costs Combining the RF and antenna elements creates major capital and operational cost savings. Nokia Flexi Multiradio Antenna System is easy to install and has fewer components by eliminating the need for Mast Head Amplier (MHA) and Remote Electrical Tilt (RET) equipment. The system also suers less wind loading than traditional passive antenna systems with RF modules/RRHs installed next to them, all of which help to reduce site rental costs. In addition, the system has inherent redundancy because the failure of one or more TRXs will not disrupt services. This reduces operational costs by enabling a more exible maintenance program.
