How do your connected objects communicate?
Many people are still unaware of the communication technologies behind connected objects. Meanwhile, they continue to multiply. In the lines that follow, you will know everything about how these objects communicate.

For the exchange of information to take place in very good conditions, it is important to choose the correct protocol. On the other hand, finding the ideal communication network and connecting it to an object is not always easy. Therefore, there are three different categories of communications. Depending on their standards, their protocols and in terms of connectivity or consumption, they have different technical specificities from each other. Point.

Short-range technologies or communications

To facilitate exchanges, some objects just need a so-called short-range technology (Between the transmitter and the receiver, the distance is small).

Flow of data exchanges:

Moreover, among short-range technologies, we also find Bluetooth and Zigbee which are very well represented.

Medium range technologies

When you want to connect an object to the internet over an average communication distance, the ideal is to use a Hub. The hub will serve as an interface between the virtual internet and connected objects.

Connected objects

How connected objects communicate

Here are the technologies through which the objects will exchange with the hub, once connected: Bluetooth Low Energy, Wifi, Z-Wave.

Connection to the internet through a hub:

If Bluetooth and Wifi are more used, it should be noted that the Zigbee (high-level protocol for the communication of small radios with reduced consumption) and the Z-Wave (wireless communication protocol dedicated to home automation) are also very in sight.

Cellular networks or long-range technologies

When you end up with objects that require communication over long distances, the only communication solution required in this case is that of the cellular network. The first two evoked are no longer effective.

Mobile cellular networks:

These cellular networks are provided by telecommunication operators and rely on GSM technology. They allow the transfer of information in very high speed but are known for a very high energy consumption. As a result, they are hardly supported by connected stand-alone objects.

Organic radio networks:

In order to rescue low-voltage devices that transfer a small amount of data, SigFox has created the Low Frequency and Low Frequency Wireless Radio Communication Network of the same name. This network suits them perfectly.

More and more connected objects

Every day, new connected objects are born and the need to optimize the use of these tools becomes enormous. In addition, existing communication technologies and processes focus on different standards and functionality.

The need to reduce energy consumption by transmitting short messages is increasing. Faced with this situation, the 5G is announced by 2020, which is supposed to overcome all the limits displayed by the available technologies. We follow closely afterwards.
