A cellular network is the same connection that any mobile phone uses. The basic idea with this kind of network is to divide a territory into a number of cells, each one with a wireless network connection served by a base station and a number of transceivers. The network provides a number of services, such as voice, text, and data.

Mobile networks are an option when a device type in a solution is not in the range of a Wi-Fi network, such as in a car. Another application that may require a mobile network device is when the solution cannot depend on the user's network, for example, if you are using a subscription for the device, and the device's activity depends on a network connection. When using the subscription network, the device will continue to do its job even if the user disables their own connection to the network.

The image below depicts the working of a standard cellular network:

We can see that a cellular antenna provides a signal to a limited region. The devices in range can then connect through a wireless network to the antenna and use the services provided by the mobile service provider, including the available internet connection.
