Air Scale RRH: Nokia gets the rest out of LTE

Friday, September 8th, 2017 | Gadgets

Nokia offers new mobile phone equipment that allows network operators to provide their 4G networks with higher capacity and to prepare them for 5G. The Finnish company announced this on 8 September 2017. The Air Scale RRH (Remote Radio Head) product line is designed to increase the performance and cell capacity of mobile operators with peak performance.

In addition, the space requirement of the technology in the radio cells is reduced by using the new single and dual-band FDD-LTE and TDD-LTE radio modules. The two TDTE and FDD LTE standards differ in that TDD (Time Division Duplex) is time-delayed duplex transmission and FDD is frequency-separated duplex transmission. The radio cells use technologies such as carrier aggregation, 4×4 MIMO and 8×4 beamforming. This increases the output power and supports other frequency bands.
Small cells at hotspots
Mobile operators who want to improve network coverage and capacity in high-traffic areas should build additional small cells. Nokia has equipped its FlexiZone Small Cells with new features. These cells are self-organizing themselves with the help of Nokia's Ultra-Dense Self-Organizing Network technology. Harold Graham, Head of the 5G Division at Nokia, said that customers should receive "technical advancements" that bring them "toward 5G".
In addition, Nokia has developed new features for its Nokia FlexiZone Small Cells for the CBRS (Citizen Band Radio Service) band in the 3.5-GHz band. These support proxy connections from Spectrum Access Servers (SAS) and CBRS devices, and offer mobile operators new options to increase network coverage and capacity within buildings. CBRS FlexiZone Small Cells can be used to provide a 'neutral host', allowing mobile operators to rent capacity to other vendors in shopping centers, hotels, and office complexes.

In order to enable effective backhauling in particularly dense city networks, where small radio cells are connected via radio with fiber-optic access points, Nokia Wavence Microwave now supports SDN for network operators.
