2G and 3G Sunsets: When They’ll Happen and How to Prepare
Billions of IoT devices rely on 2G and 3G cellular networks. These solutions offer IoT manufacturers an affordable way to keep devices connected anywhere in the world—indoors, outdoors, or on the go. But the technology is decades old, there are better solutions available, and there’s only so much bandwidth to go around.
2G and the Internet of Things: What You Need to Know
While 2G networks were built with cell phones in mind, this technology has historically been the most popular choice for Internet of Things manufacturers because it has global infrastructure, works well indoors and outdoors, consumes less power, and costs far less than more advanced cellular networks. Most cellular IoT applications currently use 2G.
