Nokia Networks announced its the Flexi Metro Remote Radio Head (RRH), 60MHz carrier aggregation for LTE and new software features for its Liquid Radio platform.
The new Nokia Flexi Metro RRH for LTE is designed for extremely dense networks in the busiest metropolitan areas using existing macro network sites. Nokia said the 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.
The software enhancements to Nokia Networks LTE-Advanced Carrier Aggregation enable evolution to 60MHz aggregation bandwidth in LTE and TD-LTE, delivering up to 450 Mbps peak downlink rates, as supported by upcoming Category 9 devices.
The company is also launching Enhanced HSUPA Interference Cancellation, a new Liquid Radio WCDMA Software Suite feature that reduces interference for up to 60% gain in uplink throughput to fit up to 30% more users per cell.
Some other new capabilities:
- 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 effective load balancing: helps 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.
“Operators are densifying their networks by splitting macro cells or adding more network layers for the vital extra capacity needed especially in metropolitan areas,” said Thorsten Robrecht, vice president, Mobile Broadband portfolio management at Nokia Networks. “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.”
