5G Standalone

Despite a slow 2022, 5G core deployments will accelerate.

Until October 2022, only about 30 operators had launched 5G core and another 25 forecasted in 2023. 5G core remains a key component of the overall network, and the operator business case will improve as vendors’ products, such as cloud native and automation tools, continue to mature, enabling improved operations and service delivery. 

The buildout of multi-vendor 5G cores intensifies.

The service-based architecture (SBA) principles on which the 5G core is based facilitate an architecture that will permit network functions from different vendors to be integrated. This will enable the operators to pick the best-in-class vendors to support them on future revenue-generating service rollouts. 

The partnership with PCPs for 5G core will go beyond trailblazers.

Operators will have more architecture choices for their 5G core. New trends will go beyond the traditional in-house telcocloud and leverage partnerships between operators and public cloud providers (PCPs). One of those will be the core as a service (Co-aaS) model. 

While most operators started deploying a non-standalone (NSA) network when first building 5G...

all North American operators are fiercely competing to build and bring their 5G SA network and services to market asap (bar T-Mobile who was the first to launch).  With $680m spent globally on just packet core, this is not a market to ignore. As of October 2022, just 30 CSPs globally had launched 5G next-generation core for standalone (SA) architecture. As vendors continue to resolve platform issues, operators will seek to reskill their staff (or hire new ones) and launch 5G core over the next two years. 5G core remains a key component of the overall 5G network, and operators’ business cases will be strengthened as automation and orchestration tools mature. Omdia forecasts that another 25 will launch in 2023, including US powerhouses, Verizon and AT&T.

5G core will enable new use cases and revenue

MNOs’ finances have also been under pressure for several years, but they must ensure they can build and operate this new platform in a timely manner. Deploying and operating the 5GC is complex and requires MNOs to upskill the workforce to better use software and automation tools. 

MNOs have significant opportunities available to them to leverage the 5GC. While some of these opportunities, such as mobile gaming and virtual reality (VR), target the consumer segment and can deliver some revenue uplift, most of the low-latency use cases will deliver benefits to the enterprise and business-to-business (B2B) segments.
