Upgrade to LTE / LTE-M for IoT

Read the brief (PDF)

Begin your move to 4G LTE today

Now is the time to plan and start implementing your technology transition to 4G LTE.

AT&T strongly encourages all of its customers to adopt 4G LTE or LTE-M service and migrate from all 3G devices as soon as possible. We currently plan to end service on our 3G wireless networks in February 2022. This will help support the explosion of mobile internet usage on the AT&T network, provide customers the best experience, and free up spectrum to better accommodate for next generation technologies and services.

As customers across every industry adopt, deploy, and depend on Internet of Things (IoT) solutions, highly secure end-to-end connectivity is essential. It’s difficult to bring a one-size-fits-all IoT network approach to every business situation. With the introduction of LTE-M, in addition to 4G LTE and satellite, businesses now have the option to have their endpoints allocated to the network that best meets their requirements.

Why Upgrade?

The AT&T 4G LTE network provides the quickest connection with the least latency compared to 2G and 3G networks. Built for IoT devices, LTE-M is a licensed low-power wide-area (LPWA) network that enhances indoor and subterranean coverage, as well as provides extended battery life, at lower costs for lower bandwidth requirements.

What I need to know?

AT&T supports innovative technology, including communications for a variety of connected devices, such as those found in cars, power meters, shipping containers, wind turbines, vending machines and more. We can provide assistance, information, and resources for businesses on their journey to adopt more advanced 4G LTE and LTE-M networks.

How do I start?

Customers deploying network technology need to plan for network evolutions and the hardware upgrades that support these changes. For this reason, we counsel our customers to make the decisions that best fit their long-term plans within the scope of the evolution of the network.
