In the Internet of Things (IoT), an IoT module is a small electronic device that is embedded in objects so that they can communicate with the internet through wireless technology. Sometimes called a ‘radio chip’ or ‘IoT chip’, the electronics inside work in the same way as those found in mobile phones that connect to the network. These modules, however, must provide an always-on, or persistent, connection to the network. This is because IoT applications require data to be sent automatically at intermittent intervals – in other words whenever required and in real-time without any additional connection or intervention required.
These modules are, therefore, engineered to be extremely durable and long-lasting since they may need to operate continuously for over a decade or more to justify their use-case and the cost of developing them for a huge number of devices.
