5G NR (New Radio) And The Networking!

Extreme data rates, low latency and high reliability all owes to 5G New Radio. The use cases for NR defined by international telecommunications union (ITU) are:

  • Enhanced mobile broadband (eMBB)
  • Ultra-reliable low-latency communications (URLLC)
  • Massive machine-type communications (mMTC)

NR is always evolving with enhancements in ultra-reliable low latency communications (URLLC) in IoT, extension of frequency to 114 GHz, extended MIMO, cellular-vehicle-to-everything (V2X), and user equipment (UE) positioning and also increasing the power efficiency.

Mobile network operators (MNOs) expect a network which can handle 5G NR advancement. MNOs can enjoy Software Defined Networking, Network Function Virtualization and Radio Access Network due to the low latency and higher throughput of 5G.

SDNs centralizes the data plane and the control plane. NFV and SDN compliments each other by decoupling and providing flexibility.

Network slicing
NFV, allows the RAN to be replaced with software-based virtual machines (VMs) for segmentation of a network into various VMs (partitioned into slices of network). These slices perform optimization for latency, throughput, and security. For instance a utility company needs to support a great number of sensors or a robotic surgery. All these need network to be sliced.

It can take place in either core network or RAN

Virtualized RAN centralizes data processing. Also, 5G NR depends on factors like wider channel bandwidths, MIMO, and higher throughput by modulation schemes up to 256 QAM .

Virtualized RANs need higher-bandwidth and lower-latency. Both the RAN determines the data handling with 5G.
Mobile edge computing

MEC is an architecture moving the processing, storage, and management closer to the RAN’s edge and it supports low-latency and on-demand services. It also make the computing resources closer to the edge of the network.

It results in reduced transport latency, enabling smart infrastructure services in autonomous driving or drone traffic control which is not possible by a centralized network.
Initially in 5G, operators balance centralized processing and MEC as there always remains a trade-off between cost and performance.

Is your network 5G ready
5G is something more than just speed. It is something to bring marvelous change in your smartphones. SDN and NFV has given much support to this technology. An MNO can opt for 5G NR by refreshing gigabit performance and low-latency.

You will migrate to a virtualized platform with much advancement in MEC and slicing depending more on software. But it requires performing tests on infrastructure for verification of data plane and control plane.It is a best way to validate performance.
