Shared equipment and capacity with public 5G
Public 5G, managed entirely by telecom operators, is an accessible solution for limited investment. The various pieces of equipment that make it up: the core network, edge (part of the core network ensuring the transfer of data from terminals or users and deployed in a distributed way), and radio access, are then mutualized among all the telecom operator's customers and subscribers. However, the customer's needs dictate the network coverage.
This is a suitable solution for tight budgets. Still, it has its limits: users have no control over the deployment of high points and therefore have limited means of action to resolve any problems of saturation, latency variability, or reduced quality, which are often the result of congestion or radio signal interference.
These public 5G network offerings are also accessible via a virtualized offer, where the operator reserves network resources for its private customer. With this offer, the network user can deploy the edge, which stays under his exclusive control. An operator can also deploy it.
Hybrid 5G network, between public and private network
Halfway between a public 5G network and a private 5G network lies hybrid 5G, where a private 5G network backs onto a public 5G network. In this case, the network user only has radio access and an edge. Other users share only the core network. Depending on the type of hybridization, network operation will be managed by an operator or by both the operator and the user (mixed model).
Private 5G networks, the solution for optimum performance
Finally, 5G private networks offer equipment and capacities entirely dedicated to the user. The various components are exclusive to the network user. In this case, no telecom operator is involved: the network user manages the operation. An integrator can also deploy the private 5G network and execute it on the user's behalf.
The deployment of high points, the share of uplink versus downlink traffic, the quality of service allocated to different users, and the functionalities deployed in the network can all play a part.
