The Internet-of-Things(IoT) refers to a network of end-user objects that are connected to the Internet.
The idea of IoT extends from the first generation of connected objects when only personal devices such as computers, mobile phones and certain automobiles had connection to the Internet.
With the IoT, non-personal objects such as home appliances, street lights, digital sign boards, traffic lights and industrial equipment are also able to connect to the Internet.
These objects are able to send information that can be accessed over the Internet and at the same time, receive information which enables these objects to be controlled remotely.
How does the IoT work? The IoT works by building fixed or mobile connectivity into an object. The connectivity can be achieved via a number of network technologies such as fixed broadband, 2G, 3G, 4G LTE, WiFi or dedicated technologies such as Zigbee, LoRa, Sigfox or LTE-M.
In most use cases, the objects are fitted with sensory components such as heat sensors, cameras or recorders that capture information from the environment and transmit these to the IoT platforms often deployed in the cloud.
