I often am asked to describe how Private LTE and Wi-Fi would coexist in an industrial company looking at adding Private LTE to its existing Wi-Fi infrastructure. Since most Industrial Customers ask the question, I decided to summarize thoughts expressed in most of these meetings. Below are my thoughts. Let me know if you agree or disagree.
How do you determine if you have a real, dedicated and secure private LTE enterprise network?
You have a Private LTE IF your enterprise network has;
a) its unique & dedicated SIM cards profile and,
b) you control the enterprise LTE EPC CORE, the user access and traffic profiles.
You do NOT have a Private LTE if you share the SIM card profile with other clients from your service provider and do not have the control of your EPC Core. at best in this case you have a semi-private LTE network.
You are responsible for delivering a fit-for-purpose, industrial/mission critical, wireless infrastructure to your internal customers. This infrastructure will have to handle all their various current and foreseeable needs. You need to deliver performance, flexibility, and efficiency for all your customers fixed, nomadic and mobility use cases. Do you think you can do it with a single new technology? What about the technologies you might already have in place and how to complement them with LTE Mobility. Let’s look at real-life Private Industrial/Mission-Critical Networks, and what you need to build them.
In recent weeks I have been meeting with many organizations in different verticals and countries. There is a common discussion occurring, centered about what wireless infrastructure is best suited for each use case. One client said it very well – “ Louis, I live in a small condo, and I am not very handy, but I would not be able to manage with a simple screwdriver. I also need a hammer, a set of pliers and a few other tools in my bag. So how can I possibly build a network with a single tool like LTE?”
