What You Need to Know About Creating a Private LTE Network

Why use a private LTE network for your IoT project? It’s all about security, access and control.

Private LTE networks are offer greater security and more control for your IoT projects.
Private LTE networks are an outstanding alternative to the open internet for connecting devices that require secure, direct connections to each other and/or your cloud infrastructure.
A private mobile telecoms network allows you to communicate with a device in the field over a cellular connection without ever touching the public internet. Yes, the public internet is great. And it offers a lot of wonderful communication opportunities.
But the public internet can pose security risks. The public internet is also often congested.
You can increase your security and control, while enjoying direct access to the devices that are mapped to your private LTE infrastructure. Of course, you can also open your devices up to the public internet, if you need.
Fortunately, it’s relatively easy to set up a private LTE network.

Private LTE network setup

In short, a private cellular network is just a communications channel between your carrier SIM card and your cloud service provider or corporate network.
A Virtual Cross Connect (VXC) connects the SIM card to your cloud service provider, joining traffic from our Evolved Packet Core (EPC) directly to your cloud infrastructure.
The Evolved Packet Core is the Telnyx Wireless engine - it’s the place where all traffic gets routed and all SIMs get registered to the network.

Why use a private LTE network?

So, even though the public internet poses security risks, there are cybersecurity tools for addressing that. VPNs are often used to access devices in the field from a local network.
VPNs are a very useful tool that offers better security than a bare internet connection. And you can use a VPN on a private LTE network, if you want that layer of security. However, without a private network—even with a VPN—your devices must still connect to the public internet.
A private network enables you to connect to devices in the field without using the public internet at all. This sort of private connection offers a few great benefits.


The main trouble with cybersecurity is that it’s designed to resist cyber attacks. Occasionally, security protocols fail, for one reason or another. Think of all the webcams, video doorbells, baby monitors, and other devices that have been breached—even though the security protocols were in place—because the owner forgot to change the default administrator password.
A better solution would be to avoid cyber attacks altogether. If your connected devices never need to touch the public internet, there are fewer possible attack vectors, and therefore fewer (if any) cyber attacks to fend off.
A private network is more secure simply because it will be targeted less than a public internet connection.


Obviously, you have more control over your private network than you do over the internet. You can set rules for the type of traffic that’s allowed to originate from your SIM cards and traverse your LTE network.
This further enhances security, since unauthorized traffic is easily detected. But it also reduces potential congestion issues caused by disorganized connections on a network. So your private LTE connections are more reliable and higher performance than connecting over the public internet.


Connecting devices directly to your private network or applications hosted on your CSP infrastructure enables you to communicate with those devices the same way you would communicate with devices that are on your local network.
This makes testing and troubleshooting devices remotely easier and more efficient because you can easily rule out the connection issues that you must account for when connecting over the open internet.

What to do with a private LTE network

The security, control, and access you get from a private LTE network enables you to leverage private cellular networks in many unique use cases.
Projects that require additional security are the obvious use cases:
  • Healthcare applications.
  • Vehicle tracking and connectivity.
  • Remote locking systems.
  • Wide area scooter and bike sharing.
  • Smart city IoT.
  • Home security systems.
The list goes on. It would be impossible to cover every use case in this space. But private networks are also ideal for the early stages of IoT projects. It’s much easier to set up, access, and troubleshoot developing IoT devices and projects when all the IoT devices are connected to a private network that you have complete control over.
Ultimately, establishing a private LTE network is more than just a security precaution or matter of convenience. A private cellular network is an asset that you can leverage for development and internal operating efficiency at every level of your business.
