How to select the right IoT protocol
The selection of the right protocol for your IoT device depends on several factors, as follows:
- Type of communication technology: Ethernet, cellular, Wi-Fi, BLE, and so on
- Type of electrical power supply: Mains, battery, energy harvesting, or any combination of them
- Electrical consumption
- Type of data transferred: Sensor values, images, sound, video, and so on
- Latency expected
- Type of application: Remote sensing, real time, smart building, industrial, and so on
Let’s explore some examples.
If you have a wired connection, power usage is generally not a problem. Maybe you are using Power over Ethernet (PoE) to feed your IoT device, or you feed it directly from the mains.
In this case, you have high power and high bandwidth available. This type of device can be, for example, a network camera, a smart Power Distribution Unit (PDU), or a wired sensor, to name a few.
In this case, you can use HTTP or...
