With LTE-Advanced telecommunication systems now beginning to be deployed, the focus has moved towards research and development of the fifth-generation telecommunication technology and services. The new fifth generation, better known as 5G technology for cellular systems, will probably reach execution stage, and be ready for deployment around 2020 or later. Future human society and economy will strongly rely on 5G infrastructure, and the impact will go far beyond existing wireless access networks with the aim for communication services, reachable everywhere, all the time, and faster. 5G technologies will be adopted and deployed globally in alignment with developed and emerging markets’ needs.

What will 5G give to world?

5G will bring new unique network and service capabilities. 5G aims to evolve current technologies in following capacities:

  • User experience continuity in challenging situations such as high mobility (at speed>500Km/h* for ground transportation) and journeys covered by heterogeneous technologies
  • Extensive capacity needs (10-100x* number of connected devices) in dense areas resolved by using high bandwidths
  • Key enabler for the Internet of Things by providing a platform to connect a massive number of sensors, rendering devices and actuators with stringent energy and transmission constraints
  • Mission critical services requiring very high reliability (>99.99%*), global coverage and/or very low latency (<1ms*), which are up to now being handled by specific networks, typically public safety
  • Integrating networking, computing and storage resources into one programmable and unified infrastructure
  • Optimized and more dynamic usage of all distributed resources, and the convergence of fixed, mobile and broadcast services
  • 100 X in user data rate reaching a peak terminal data rate ≥ 10Gb/s*
  • 1,000 X in number of connected devices reaching a density ≥ 1M terminals/km2*

Virtualization in mobile network deployments which would in turn bring the following benefits:

  • Relaxing cost pressure
  • Enhancing automation levels
  • Decoupling software functions from the resources
  • Allowing faster service introduction (1/1,000 X* in service deployment time reaching a complete deployment in ≤ 90* minutes)
  • Providing service and network performance analysis and optimization

Hence, 5G aims at unifying all the technologies that we use and work on today. Aricent has a clear advantage in all the existing and upcoming telecommunication and related technologies, and will be in a leading position to contribute towards 5G.

Candidate Technologies for 5G

Designing 5G, which would simultaneously meet future demands of all humans, devices and technologies, calls for techniques that are capable of being used:

  • Wide and high carrier bandwidths
  • Flexible resource allocation
  • Heterogeneous set of integrated air interfaces
  • Advanced multi antenna beam forming
  • Non-orthogonal multiple access (NOMA): Multiple users will be allocated at different power levels, depending on their channel conditions
  • Massive MIMO: Very large number of antennas, that is, orders of magnitude higher than current configuration in LTE
  • Full duplex: Simultaneous transmission and reception on the same frequency and time resource
  • Millimeter wave communications: Rich millimeter wave frequency spectrum which ranges from 3 to 300 GHz
  • New interference mitigation
  • Backhauling techniques
  • Installation techniques, and so on.

5G networks will incorporate cellular and satellite solutions which have remained the core expertise of Aricent for long. 5G will also support seamless and reliable handover between heterogeneous wireless access technologies. The deployment of ultra-dense networks with numerous small cells will require it. Hence, 5G will be driven by software rather than infrastructure. Network functions are expected to run over a unified operating system for meeting performance targets.

Therefore, in order to achieve the required performance, scalability and agility and to monitor the users’ quality of experience through new metrics combining network and behavioral data while guaranteeing privacy, 5G will depend heavily on emerging technologies such as:

Conclusion

5G appears to be an industry changer which aims at unifying all existing technologies. It will integrate telecom with IT and will bring all computation and storage resources into one programmable and unified infrastructure which will allow for an optimized and scalable usage of all distributed resources. This will result in a common high-capacity global infrastructure.

5G systems have to resolve the challenge of handling the anticipated intense growth in the number of terminal devices, the continuous growth of traffic (at a 50-60% CAGR), and heterogeneous network layouts without causing a dramatic increase of power consumption and management complexity within networks. As a result, 5G will have to be designed to be a sustainable and scalable technology.

In addition, cost reduction through automation and hardware usage optimization will feed the development of sustainable business models for all ICT stakeholders and will considerably bring down the cost.

Hence, Aricent will play a crucial role in the development and deployment of 5G with its given set of expertise in telecommunication and focus on leveraging Aricent IPRs and products, Internet of Things (IoT), Analytics, Provisioning Activation framework for SDN NFV and mobile applications. Thus Aricent will support its customers and bring out the excellence and innovation in all the related domains.

Once 5G technology reaches deployment stage, life will undergo change. All humans and machines will be on single infrastructure, thus, enabling an actual ‘connected’ world.
