5G represents not only a new Radio technology, but also a significant evolution of the network architecture. This is particularly relevant for Industrial environments, where the network architecture must support specific latency and resiliency requirements. Below are two deployment models that will be commonly used in this next Industry 4.0 private networks.
Hybrid Deployment Model
For some industrial applications, a valid model is to reserve a slice of the public 5G infrastructure and manage it in a customized fashion as a private network, while allow public 5G traffic to share the same physical infrastructure. In this case, it is practical to have a Service Provider own and operate the network; therefore, the Service Provider would install local radio and the fronthaul network equipment to carry the traffic back where it can be managed. Industries want to ensure their network is private from outside traffic, and calibrated for their needs. This does not preclude the Service Provider to use the same infrastructure for public 5G traffic; however the network slicing in the fronthaul network will insure a strict separation of traffic flows. Some processing (for very low latency applications) can be done on customer premises, while others can be backhauled to the Service Provider data centres.
Private Deployment Model
In this model, the whole network is private from a 5G point of view, and have all equipment deployed on the customer premise. There is no sharing of radio and fronthaul network resources between private traffic and public 5G. This provides a localized network, with a highly customized resource allocation model. Typically, the industrial customer owns and operates the entire private 5G network (radio components, fronthaul network and RAN); however, it is possible for Service Providers to manage highly customized Private 5G networks for specific large industrial customers.
The network connectivity, fronthaul or backhaul, between various Private 5G components (5G Antennas, RAN processing, edge computing) is a critical element in either deployment model.
Canoga Perkins is focused on building networking equipment specifically designed to for Private 5G fronthaul and backhaul network connectivity, and to provide the necessary flexibility for Hybrid and Private Deployment models.
