NEC looks at the key technologies required as industry moves towards the establishment of 5G next generation mobile networks

MWC 2015: NEC outlines vision for mobile networks of 2020

NEC Corportation will be outlining its 5G next generation mobile networks vision at Mobile World Congress 2015 next week on 2-5 March in Barcelona, Spain in hall 3, on stand 3N10.

It has issued three white papers focusing on: the “Network evolution toward 2020 and beyond”, which outlines the key enabling technologies that will be required as we progress towards a 5G world; “Reinventing Transport Networks for the Future”, which focuses on mobile backhaul; and “Massive-Element Antenna for Small Cell solutions in 5G”, which focuses on Massive MIMO, one of the influential technology elements of 5G.

NEC believes that whereas 3G and 4G mobile network innovations have driven a revolution in personal communications, the biggest impact of next generation networks will be felt by society at large. The flexible integration of future mobile networks with ICT-enabled urban and industrial infrastructure will bring wide ranging benefits to consumers and businesses in a diversity of vertical sectors. 

Relevant technologies will enable the world to better support growing, ageing and more urban populations. This includes ultra-low latency connectivity for driverless cars, kilobits per second connectivity for M2M sensor networks for health and environmental monitoring, and up to hundred megabits per second for ultra high definition video broadcasting to mobiles.

“Network evolution toward 2020 and beyond”

NEC’s white paper outlines the potential use cases and key enabling technologies in the Network 2020. This includes more intelligent transport systems that use sensor information and video from connected cars and road infrastructure and big data analytics to help people drive more safely, reduce congestion and curb greenhouse gas emissions.

New personal entertainment services, including 4K ultra high definition video, will enable consumers to turn on “metadata labels” relating to content, for example the match statistics relating to players in a football match when at home or in a stadium on their mobile. 

At the same the network will need to support improved logistics visualisation, which integrates the location information relating to individual items within a cargo shipment that are the responsibility of a range of different companies, with the operational information relating to the transportation system itself.

This includes the receiver’s availability – determined using an Application-to-Person text message service – road congestion levels and weather conditions, the optimum route can be planned for each delivery.

The high capacity, low latency, power saving, flexible architecture to support this diversity of services will be based on SDN/NFV and C-RAN technology. This will enable traffic to take the best path through the network depending on real-time demand and the specific latency, bandwidth, per-bit cost, safety and security requirements of each of these new social services.

“Reinventing transport networks for the future”

As more consumers become dependent on mobile services for work and leisure, operators need to keep pace with traffic growth while facing the challenge of Over The Top (OTT) services that are affecting their bottom lines.

High capacity, wide bandwidth microwave transport – combined with the resource optimisation capabilities of SDN/NFV and a powerful Telecoms Operations and Management System (TOMS) and Traffic Management Solution (TMS) – provide a scalable solution to overcome the challenges of rising cost and customer expectations of a better quality network experience and new innovative services.

Mobile backhaul will play a key role in enhancing the consumer’s end-to-end Quality of Experience of the network with SDN/NFV providing the ability to dynamically steer services around failures in the network and optimize bandwidth usage.

“Massive-Element Antenna for Small Cell solutions in 5G”

This white paper outlines the future direction of Radio Access Network (RAN) technology, geared towards the practical application of 5G technologies. NEC is developing the “Massive-Element Antenna,” and using it in its fundamental research efforts towards advanced beamforming, one of the elemental technologies of 5G. In this document, NEC will introduce the effectiveness of the massive element antenna for small cells, based on the results of this research.

Through the release of these white papers and through further research and development, NEC will continue to exercise its leadership as a company that uniquely has very innovative technologies in both the networking and computing domains. NEC is committed to being a social value innovator using the new “2020 network” to help create a better world.
