Though 5G will play a role in multi-access edge computing, the precise way the technology gets deployed will vary. In some cases enterprises will build their own private 5G networks, isolated from the wide area network in the same way that Wi-Fi networks are isolated.
Connectivity to WANs will be possible, but in the same way that Wi-Fi-connected devices can reach public networks, when intended and as authorized.
In other cases enterprises may buy design and operation services from mobile operators, though the private networks remain logically and physically isolated from the public networks.
In yet other cases a virtual private network might be created and suported using only public network infrastructure.
Traditionally, private networks have been preferred when enterprises want high isolation from public networks, plus full control and lower cost, higher-performance in-building networking. Some 50 years ago, the use case was support for personal computers and peripherals connected to servers and cabled networks were the platform.
These days, Wi-Fi tends to dominate for general purpose computing requirements supporting devices of all types. Mobile phone support remains a mix of public network access for voice and messaging, while data access can use either Wi-Fi or the public network.
5G plus multi-access edge computing allows new permutations. Some 66 percent of mobile operators polled by GSMA are looking to use their core assets to support private enterprise networks. Some 59 percent also believe they can use their public networks to do so, operating with service level agreements.
In all likelihood, quite a mix will emerge.
