What Exactly Is IoT And How Do IoT Devices Communicate?

September 09, 2019 / SHERRY MCKENNA

Experts predict that by 2025, over 64 billions of devices will be connected to the internet. IoT can potentially generate $4T to $11T in economic value by that time. That's why all business owners should get interested in the opportunities IoT brings for increasing operational efficiency.So what exactly is IoT? In a nutshell, it's a system of interrelated devices and objects that are embedded with technology that enables them to transfer data over a network. The essence of IoT is that it brings in everyday objects such as smart fridges or wearables equipped with sensors connected to a network. These devices can be controlled and monitored remotely.You're probably wondering how IoT devices communicate. Keep on reading to find that out. IoT devices transfer data with the help of different systems and protocols that offer seamless connectivity.A standard model of communication involves several different protocols like LwM2M every time a device communicates with another one through the internet. The data travels from the physical device through the network to be transported into a session. Eventually, it ends in the application protocol that allows using, manipulating, and re-transmitting data. The larger the IoT network gets, the more complex are the protocols required to ensure smooth communication.
