"A report by network intelligence biz Ookla and analyst firm Omdia, " A Global Reality Check on 5G SA and 5G Advanced," [PDF] claims that the global adoption of 5G SA is moving into a new phase where regional differences are starting to be felt in capabilities rather than the extent of network coverage. To put it another way, the tier-1 networks in North America have completed their transition to 5G SA and many Asian countries such as India went directly to it."
"As Reg readers are aware, 5G SA refers to networks with both a 5G network core and a 5G radio access network. Many early adopters bolted the new radios onto their legacy networks as a stopgap, but this failed to deliver the promised benefits for the new technology. The report states that the industry is about halfway through the 5G lifecycle, and 5G SA should now be regarded as the foundation for building 5G Advanced capabilities, including new service delivery models."
"5G Advanced goes beyond the network improvements in SA to include myriad small enhancements in how devices talk to towers, targeting comms bottlenecks and reliability, with capabilities such as Sub-band Full Duplex (SBFD) letting a device send and receive at the same time to eliminate wait times, for example. But many of these capabilities "benefit most from a fully deployed SA core as their foundation,""
North American and Asian markets have largely transitioned to 5G Standalone (SA) mobile networks, delivering high-speed connectivity and improved responsiveness. Many European networks lag in SA deployment, creating a growing disadvantage as new capabilities emerge. 5G SA combines a 5G network core with a 5G radio access network; retrofitting new radios onto legacy cores did not provide full benefits. The industry is about halfway through the 5G lifecycle, and 5G SA forms the foundation for 5G Advanced features and new service models. 5G Advanced adds numerous link-level enhancements, such as Sub-band Full Duplex (SBFD), that require mature SA cores to achieve their benefits.
