Telecom equipment vendor Nokia Networks today announced its Flexi Metro Remote Radio Head (RRH), 60MHz carrier aggregation for LTE and new software features for Liquid Radio.
The new launches are aimed at improving customer experience by creating higher density macro networks with more capacity and throughput.
Nokia Networks Flexi Metro RRH for LTE
The company said the new Nokia Flexi Metro RRH for LTE enables telecom operators to build dense networks in busy metropolitan areas using existing macro network sites.
Its small volume (<5 liters) and light weight (<5 kg) allow operators to utilize telecom sites which are typically unsuitable for conventional units.
Nokia Networks said RRH’s sensitivity can be tuned and output varied from 2 x 5W down to 2 x 50mW to match any deployment’s need for high capacity mobile broadband. Combined with Nokia’s Centralized RAN, the Nokia Flexi Metro RRH allows more cells to be concentrated in a given area.
Thorsten Robrecht, vice president, Mobile Broadband portfolio management at Nokia Networks, said: “As the distance between cells decreases and network layers increase, mobile devices cause greater interference. Liquid Radio realizes the full performance of high density macro networks with increased cell density, less interference and maximum throughput.”
Software enhancements to LTE-Advanced Carrier Aggregation
The company said software enhancements to Nokia Networks LTE-Advanced Carrier Aggregation enable evolution to 60MHz aggregation bandwidth in LTE and TD-LTE, delivering up to 450Mbps peak downlink rates, as supported by upcoming Category 9 devices.
Enhanced HSUPA Interference Cancellation
Nokia Networks is also launching Enhanced HSUPA Interference Cancellation, a new Liquid Radio WCDMA Software Suite feature, to reduce interference for up to 60 percent gain in uplink throughput to fit up to 30 percent more users per cell.
Features of Nokia Liquid Radio Software Suite
HSPA Carrier Aggregation with Dual-Band HSDPA: uses two 5MHz WCDMA carriers on different bands to double downlink peak rates to up to 42Mbps and Dual-Cell HSUPA enables devices to upload data simultaneously over two adjacent carriers to raise peak transfer rates to 11.5Mbps – both supported by upcoming terminals.
LTE-WCDMA and LTE Intrafrequency Load Balancing for load balancing: helps global telecom operators eliminate congestion in highly loaded networks and better optimize resources between users.
HSPA rapid receiver for high-speed trains enables operators to deliver better voice quality and faster uploads for passengers commuting (at 250-350 km/h) in and out of megacities and other busy areas.
Nokia’s Services for HetNets help solve the complexities of deploying high density networks for operators. Overall costs can be reduced by adding capacity in an intelligent manner, only where and when it is needed. Advanced planning and optimization services ensure that all layers of the network work seamlessly for subscribers.
