The 450MHz band has been a long-term option for applications that demand large area coverage. As a low frequency originally designated to 2G networks, it has had a long heritage of performing tasks, such as providing the connectivity for emergency calling networks and connecting the earlier generations of smart meters. However, as the 2G sunset continues across the globe, the 450MHz band is entering a second life as a network for IoT and critical applications.
The physics of the 450MHz band are perfect for the wide area coverage that IoT demands. The band can support CAT-M and narrowband-IoT (NB-IoT) technology, making it a no brainer in many cases.
The 450MHz band has been a sleeping giant, set aside for utilization in critical communications during the 2G and 3G eras. Now, however, interest has re-ignited because the bands around 450MHz support LTE CAT-M and NB-IoT, making these ideal for IoT applications.
