Gearing Up for Network Slicing


The number of 5G deployments has ratcheted up. As of the end of August 2020, the GSA reported there were 118 5G networks among commercial operators and another 279 mobile operators carrying out trials. ABI Research estimates there were 234 million subscribers worldwide by the end of 2020. As these 5G commercial deployments grow in number, the focus is shifting to what services will be supported. “Network slicing” is a key concept enabling the potential of 5G. Importantly, network slicing can offer different service levels of network availability, throughput, latency, level of security, quality of service, and several other performance indicators. Mobile operators are exploring the potential of network slicing. Here is a snapshot:

  • In January 2019, senior management of AT&T (U.S.) declared they would be using the virtualization of its radio and core network assets as a platform for network slicing.
  • In March 2020, Singtel (Singapore) announced a network slicing trial with Nokia to automate the delivery of digital services, giving Singtel greater control of services a…
