IoT NB and CAT M IoT for Secure Connection IoT NB and CAT M IoT come under massive IoT connectivity of lower power wide area networks, also known as LPWANs, with wireless cellular communication technology for IoT. It is a connectivity protocol developed by multiple telecom organizations known as 3GPP and where 3GPP stands for 3rd generation partnership project, which also developed 2G, 3G, 4G, and 5G. Legacy Networks , NB-IoT and CAT-M IoT technology are used differently based on the strength of the capabilities, as discussed below. NB-IoT NB-IoT stands for narrow band IoT, a standard-based LPWAN that enables a range of new IoT devices and services. They minimize device complexity and can co-exist with 2G, 3G, and 4G mobile networks. NB-IoT can transfer limited data and work on a small scale, such as their use cases consuming less than 1kb daily. Still, they have high security and reliability because it operates within a licensed spectrum and has a battery life of more than ten years. ...
