The IoT industry adopts LTE technology. 

Self-driving cars, smart homes, connected cities - the Internet of Things (IoT) is optimising the way we work, live, and play - and growing at lightning speed. 

Statista estimates 30 billion IoT connected devices by 2020 and 75 billion by 2025.

Gartner is projecting $300 billion in revenues for IoT suppliers alone.  

To provide bandwidth for the constant flow of new connections, the wireless industry is evolving to LTE technology (LTE for Long Term Evolution), which offers greater bandwidth, faster speed, and ultimately, better reliability. 

With the sunset of 2G and 3G networks on the horizon, the IoT industry moves to LTE to preserve the longevity and reliability of solutions with a typical lifespan of 10 years. 

The challenge is, the vast majority of IoT applications – metering, track and trace, fleet management, and many more – don’t need the speed and throughput of LTE. 

These solutions send small bits of data with low latency. 

So, how can developers strengthen the business case? 

Enter LTE Category 1! 


LTE Cat 1 - an intermediate speed standard

Specifically designed for Machine-to-Machine (M2M) and industrial IoT applications, LTE Cat. 1 provides a maximum of 10 Mbit/s downlink speed and 5Mbit/s uplink compared to LTE's peak downlink speed of 300 Mbps. See some LTE speed tests done across the U.S. in November 2019.

The result?

LTE Cat. 1 is ideal for solutions not dependent on speed that still require the longevity and reliability of 4G in the decades ahead.

LTE Cat. 1 Modules

Thales was the first to innovate LTE Cat. 1 M2M modules launching a family of solutions combining efficient connectivity with lower power consumption and improved cost efficiency.

Cinterion® ELS31
