Welcome to 2023! I introduced Private 5G networks in a previous post – https://www.vamsitalkstech.com/5g/introducing-private-5g-networks/. I also found myself helping global customers build these 5G networks over the last 18 months and thought it best to discuss how one can go about them at a high level. Deeper architecture posts will follow in 2023.
A private 5G network is a mobile network typically owned by a corporation or commercial or educational institution and not open to the public. Private networks can use licensed, unlicensed, or shared spectrum such as in the US where Citizens Broadband Radio Service (CBRS) is used. The architecture of a private 5G is essentially the same as those of a commercial public 5G network being built by CSPs (Communication Service Providers). Industries such as manufacturing, logistics, and transportation will lead the way in adopting private 5G as remote areas, rural areas and shop floors may not always have the best connectivity. Building and deploying a private 5G network can provide a number of benefits for organizations, including increased control over their network infrastructure, improved security, and the ability to tailor the network to their specific needs.
Illustration: The two ways to deploy Private 5G
The above illustration captures the two main ways to deploy private 5G networks. Organizations can either develop and manage their own private 5G network or outsource it to a mobile network operator (MNO) or systems integrator (SI) who typically deploys into a hyperscaler like AWS. In the second approach, organizations use a cloud-based service provider to build and deploy their private 5G network. This approach allows organizations to take advantage of the scalability, security, and expertise of the service provider, while still maintaining control over their network infrastructure. Cloud-based deployment can also be less expensive and less complex than on-premises deployment, as the service provider is responsible for managing and maintaining the network infrastructure.
Private 5G networks open a whole new world of opportunities for businesses across the board, from automotive, financial services, manufacturing, transportation, and education to retail, healthcare, and entertainment. Whether or not the premises are located inside a public 5G coverage region, a private 5G network enables major enterprises and public sector organizations to offer a custom-tailored 5G experience across indoor or outdoor facilities where high-speed, high-capacity, low-latency connectivity is essential. Both approaches highlighted above have their own advantages and drawbacks, organizations should carefully evaluate their specific needs and requirements before deciding which approach to take. They should also consider the trade-offs between control, cost, and ease of management when making their decision.
