The best possible network quality

The Orange network already covers 99% of the population with 4G in mainland France, including 97% of the population living in communes of less than 5,000 inhabitants, and more than 60% of the population in mainland France with 5G.

For 13 consecutive times, Orange has been recognized by the ARCEP (French Regulator) number 1 on the quality of its mobile services: calls, SMS and mobile internet.

Orange Wholesale France gives you access to the same network cores as those used for the retail market to enable you to enjoy the best possible network quality.

A mobile network consists of 2 parts: “access” and “heart”.

The Access Network: Antennas

This is the “base station subsystem”, which is used for radio broadcasting.

Mobiles communicate using base stations. Each base station is equipped with transmitter-receiver antennas and an electronic device which processes the signal.

Each station covers a specific area, hence the term cellular network. Several stations are centred on a single base station controller. This is the main control for the base station subsystem. It constantly monitors the quality of radio communication between the mobile and the antenna. If the mobile moves away from the antenna, the concentrator anticipates the movement and transfers the waves to another antenna.

When a call is received, the cellular tower converts the electromagnetic waves received from the mobile into digital data that are transmitted via the fixed network to the Backbone Network by copper wire, fibre, or radio waves. These mobile backhaul connections between the station and the backbone can be provided to mobile operators by Orange Wholesale France. This conversion happens in reverse when the call is dispatched.

The Backbone Network

Once the signal is routed to the Backbone Network, towards a switch, if the terminal being called is a mobile, it must then be located.

A localisation server permanently lists the mobile terminals that are in the area. This data is contained in a general database. The switch uses the database to locate the mobile being called and dispatches the call.

The Backbone Network acts as an interface between the other networks, thereby enabling mobile subscribers to communicate with fixed number network subscribers, the networks of other operators, and the internet.
