Mesh networking, RFID, and Bluetooth

Many protocols are yet to be mentioned as part of IoT. Here, we’ll highlight three more to add to your toolkit, with a special emphasis on RFID technologies, given their prevalence within open source and industrial communities.

RFID

RFID technologies are used to identify and track objects through radio waves, and in IoT, they are used to track a wide array of devices or sometimes people. There are two main types of RFID technologies: passive and active. Passive ones use tags that do not have power sources and instead depend on the power transmitted by the reader for them to send their data, while active systems use tags that have power sources and can transmit data over longer distances.

RFID technologies can identify and track objects without necessitating a direct line of sight, making them perfect to use within environments where objects are difficult to track, such as in manufacturing environments or within warehouses. They can...
