Critical 2G/3G cellular network shutdown dates are quickly approaching in the U.S. Additionally, sunset schedules are affecting organizations worldwide, and a number of deadlines now loom on the horizon as network operators roll out new LTE networks. Since the rollout of 5G for widespread use in commercial and industrial applications will take 5 to 10 years, now is the time to create an action plan for network migration to LTE, which will be well-supported long into the 5G era.
The transition creates a number of challenges because it is not a linear process across networks or carriers, and it differs by region. For example, depending on where you are in the world, 2G connectivity may outlast some 3G networks, especially in Europe. However, with increasing 4G proliferation and 5G already being rolled out in some regions, carriers' focus has been shifting away from GSM and UMTS networks for quite some time now to free up frequencies for the new technologies.

The following are some of the key anticipated cellular carrier 2G/3G sunset dates. It is important to note that there is no guarantee of service beyond these dates.
Starting from the shutdown dates, 2G and 3G devices will no longer connect to the network and will cease communicating within your organization. Therefore, many are asking how to upgrade legacy communications devices beforehand to ensure continued business operations.
With 2G/3G sunset already underway, and 4G LTE available worldwide, the time to plan your device migration is now. Our video shares more information about "4 Steps to 4G" planning.
To start your LTE migration planning, you will need to assess your applications and affected devices. Determine your current and projected use cases and how they may be impacted by new LTE technology. Be as forward thinking as you can to answer these questions along with any larger business situations you need to solve with the new network technologies.
Here are some key business and technology questions to analyze:

With 2G shutdowns already occurring and 3G network shutdowns coming soon, migration strategies are vital for network engineers and administrators to manage the transition to 4G LTE and 5G. Your business may be wondering if it is time to factor in 5G in your long-range planning as well. Note that it is important not to wait for 5G networks to be ready for deployment, as full 5G deployment for commercial and industrial IoT applications is at least 3-5 years away, after the 2G/3G shutdowns are complete.
The good news is that forward thinking providers like Digi International are building 4G products for critical infrastructure and industrial applications today that will migrate seamlessly to 5G when the time comes, without having to replace deployed devices. Turn to Digi for the routers, software and planning services you need to make your LTE migration a complete success.
