An IoT (Internet of Things) module is a small electronic device that enables objects to be connected over a network to implement IoT connectivity. These modules are small devices that enable network communications through wireless networks by sending and receiving data. An IoT module typically contains the same communications technology as that found in mobile phones; these modules, however, must provide persistent or ‘always on’ connectivity since they need to be able to send data automatically without connectivity having to be enabled by an outside source.
These modules are designed for low power use and are engineered to have an extremely long life and be extremely durable. Eventually billions of objects are likely to be connected in an IoT system and therefore these modules must be able to be installed and not require human intervention for long periods. It is estimated IoT devices need to continuously operate for a decade or more to justify their use and cost.
