Nokia to help boost 4G network performance as 5G stepping stone

Nokia announced it is extending its portfolio of mobile broadband solutions to give operators new flexibility to meet consumer demand and enhance mobile network performance of 4G networks as they evolve towards 5G.

With the goal of helping cellcos enhance network performance where they see the greatest demand – with first deployments traditionally in busy city centers – Nokia says it has defined a sustainable network evolution path that will allow operators to leverage existing 4G investments and maximize assets such as spectrum to implement higher performance where and when it is needed in the network.

To that end, Nokia is adding new dual- and single-band FDD-LTE and TD-LTE radios to its AirScale Remote Radio Head portfolio , enabling operators to increase peak performance and cell capacity while reducing space requirements at cell sites.

The new radios leverage carrier aggregation techniques, 4×4 MIMO and 8×4 beamforming, while addressing demand for higher output power, extending frequency band support and simplifying network rollouts.

To augment heterogeneous network deployments and boost coverage and capacity in the busiest hotspots – especially in dense urban environments – operators will need to deploy the next wave of small cells. The

Nokia also introduced ultra-dense self-organizing network features for its Flexi Zone small cells to simplify heterogeneous network deployments, and boost coverage and capacity in the busiest hotspots – especially in dense urban environments. The SON features address issues caused by reducing the distance between new and existing small cells and ensuring continuous optimization even as further densification occurs.

Nokia has also added new features to its CBRS small that support spectrum access server and CBRS device proxy connectivity. Nokia says this will offer operators new options for boosting coverage and capacity, particularly inside buildings.

To provide backhaul flexibility for ultra-dense heterogeneous city networks – where microwave transport is used to link small cells to fiber access points – Nokia’s Wavence microwave now supports carrier SDN. Operators will benefit from new intelligence and automation, including rapid power-up of virtual network functions and adaptable parameters to support changes on the RAN, such as when people move from work to home, Nokia says.
