An IoT module is a chip that is used to communicate with wireless networks and enables Internet of Things (IoT) objects to function. They support a wide range of wireless technology standards (including Bluetooth, for example) and provide the pervasive and persistent internet access that IoT objects need to report their state and to receive incoming data.
These modules must provide always-on connectivity so that IoT applications can send data automatically, in real-time and at intermittent periods as required or when their sensors need to transmit data. They are also engineered for extreme durability and longevity (for a decade or more) to justify the use case and cost of the technology.
IoT devices are also likely to be deployed in extreme environments and unusual locations, such as shipping containers or under water, and must be able to withstand extreme temperatures, vibration and humidity.
