For some time now the name of Internet of Things, or “The Internet of Things”, IoT or even Internet of Things has been spreading. More commonly in French, this refers to the many connected objects, the nature of which can easily vary. The most common of these is the connected watch , also called a smartwatch. However, this name of connected object also concerns cameras, scales, speakers, and other bulbs.


What are the connected objects of IoT, the Internet of Things?

A connected object is an object that can function and be controlled by the internet. This connection can be made between the object and a user, or even between two objects. If applicable, this is then an M2M connection, namely Machine to machine. It is this interaction that characterizes the Internet of Things, or Internet of Things.

This phenomenon imposes itself as a distinctive element in the various stages of the web:

  • the birth of the Internet and access to information thus corresponds to Web 1.0;

  • the development of social networks and mobile devices have led to the emergence of web 2.0, also called social web;

  • the internet of things, for its part, has brought the web to version 3.0.

Behind the name of Internet of Things is a large number of varied objects related to various sectors. One of the most represented is the health sector, with devices that measure distances traveled and energy expended . Home automation devices are also very numerous. As a reminder, home automation is the set of techniques and technologies that centralize the use of electronic devices while offering them the possibility of interacting.

How do connected objects work?

The term connected object is used more and more often, but what does it really mean? Is it necessary to subscribe to a particular package to be able to use my connected objects? Response elements.

Why this term of “connected” objects?

Connected objects need to exchange information. These are therefore wireless devices that use wave frequencies to transmit data , like telephone waves or even Wi-Fi. Information is thus exchanged over the Internet.

The expansion of this type of object is enabled by  replacing IPv4 addresses with IPv6 addresses . To simply summarize the difference, IP addresses are series of numbers. IPv4 addresses consist of 32 bits, or 4 bytes. As for them, IPv6 addresses are 128 bits long, or 16 bytes.

IPv6 addresses are therefore much longer, and therefore many more. The IPv6 protocol was developed due to the exhaustion of IPv4 addresses. It is this very large number of additional addresses available that allows connected objects to spread. The simple fact that they are connected indeed implies the need to be assigned an IP address.

Do I have to pay a flat rate to use a connected object?

By nature, connected objects need to transmit data in order to be connected. However, as with a smartphone, which can be considered the first of the connected objects , you have to pay to use data. The explanation is simple. Data in transit occupies part of the mobile data network. This network needs maintenance and upkeep, work that must be financed.

This is why mobile data is chargeable. The principle is very similar to that of highways. Similarly, a bad network or an overload of it leads to slowdowns. You therefore need a package to use a connected object such as a smartwatch. On many objects that connect via Bluetooth, the subscription is dependent on that of the object to which they are connected. This is the case, for example, with smartwatches.

Do I have to have a SIM card dedicated to my connected object?

The answer is simple: no. This is by no means an obligation, but it may be a possibility. It is indeed imperative to have a package to use the connected object, in order to have the right to use the mobile network. This plan can be managed in two different ways.

Here are the two possible configurations:

  • the connected object is attached to the smartphone, and then benefits from the data of the mobile plan;

  • the connected object has its own SIM card, and can benefit from its own package.

Use a connected object with your smartphone

By using a connected object with a smartphone, the connected device is managed from the mobile. And this, including for the use of mobile data, since it is those of the package that are consumed . The principle is in fact the same as for connection sharing. The smartphone is thus used as a modem, like an internet box.

To simply explain what is happening, we must see the smartphone works as a relay between the object and the network . The object is connected to the smartphone which is itself connected to the network. Thus, the object exchanges data with the network, but systematically passing through the smartphone.

For this relationship to work, it is therefore necessary:

  • have a plan with mobile data;

  • activate their mobile data (3G / 4G / 4G +);

  • activate bluetooth.

Are all connected objects compatible with all smartphones?

Unfortunately no. And that is the limit of this type of use. In general, especially in the case of the smartwatch, it is necessary to ensure that the two objects are compatible with each other . What is more, it is not always easy. Not only do brands need to be compatible with each other, but often models within brands also need to be compatible.

It is also necessary to ensure the correspondence of the operating systems and the system edition. To use the example of watches, just because an Apple Watch is compatible with one version of iOS does not mean that it will be compatible with the next. It is therefore imperative to ensure the compatibility of the two objects before making a purchase . In absolute terms, it may also be preferable to have a SIM card dedicated to the device in some cases, for simplicity.

How much data does a connected object consume?

It all depends on the object and its function. If it's just a matter of transmitting some information like a smartwatch does, for example, you don't have to want a lot of mobile data. However, depending on usage, an offer with 50 MB can quickly become limited . You should therefore not hesitate to go through a test phase by regularly checking the mobile data consumption of your subscription.
