Connectivity options are vast and varied in the world of Internet of Things (IoT). LTE-M (also known as CAT-M) stands in the array of available technologies. It is equipped with some unique advantages and particularly in scenarios where efficiency and battery life are paramount.
LTE-M is a Low Powered, Wide Area Network (LPWAN) technology and is basically tailored for IoT services that don’t rely on a constant power supply as well as can handle small data transmissions. It is designed to offer significant benefits for specific use cases and simultaneously remain cost-effective.
One standout feature of LTE-M is its ability to extend signal coverage beyond the reach of 4G and 5G networks. It boasts impressive battery longevity too for connected devices. It has the potential to operate for up to a decade on a single charge. Hence, it is ideal for applications where device longevity is crucial.
Meanwhile, the 4G and 5G networks are optimized for high data throughput and low latency. Both the networks are suitable for applications which demand constant connectivity and large data transfers.
Vodafone’s recent endorsement of LTE-M emphasizes its role as a cost-effective solution. Nick Gliddon, Business Director at Vodafone UK, said that the power of LTE-M is the ability to choose the right tools for the right job. The sentiment highlights a crucial point and it is that not all IoT applications need the high-speed and high-capacity features of 5G.
The debate between LTE-M and NB-IoT (another LPWAN technology) highlights further the tailored nature of connectivity solutions. LTE-M offers higher average speeds (up to 300 kbps) compared to NB-IoT (around 20 kbps). It is best suited for mobile and event-based use cases. NB-IoT excels in challenging environments where reliable coverage is essential such as underground water pipes or smart meters located in basements.
