LTE Cat-1 and its Position in the 2G/3G Sunset

LTE Cat-1 and its Position in the 2G/3G Sunset

January 3, 2023

According to Machina Research, the number of global loT connections will reach 27 billion by 2025. Among them, the total size of cellular loT connections is expected to exceed 5 billion. Technologically, as the world is moving towards the 5G era, and 4G has become the mainstream mobile communication system, shortcomings of 2G/ 3G become increasingly obvious either regarding spectrum allocation efficiency, wireless performance, or operation and maintenance costs. The worldwide 2G/3G sunset is in progress with many countries giving their own timelines based on their needs for telecommunications networks.

The retirement of 2G/ 3G requires mature alternative technologies to meet the development needs of low and mid-speed loT applications (within lOMbps on the downlink and 5Mbps uplink) that account for 90% of the overall cellular loT connections. Among them, L TE Cat 1 is the preferred alternative option for loT scenarios balancing between the consideration of both wireless performance and migration cost.
