History of Radiocom 2000
Radiocom 2000 was a pioneering mobile phone network in France that introduced the concept of cellular telephony in the late 1980s. It was launched with the "Réseau Haute Densité" (RHD) feature, which allowed for dynamic cell switching and frequency allocation within a cell.

The network was initially deployed by France Telecom Mobiles and covered nearly the entire French territory. The first Radiocom 2000 phones were bulky and expensive, but they marked the beginning of a new era in mobile communication.
Radiocom 2000 was the first network to offer regional abonnement options, including Île de France, Région Lyonnaise, PACA, Province, and National. The phones were manufactured by Matra, Radiotel, Alcatel, and Sagem, and featured rechargeable Nickel-Cadmium batteries.
By 1988, Radiocom 2000 had reached 60,000 subscribers, with over 90% of the phones installed in vehicles. This was also the year that competition emerged in the form of the Société française de radiotéléphones (SFR), which used the NMT-F standard.
Despite initial plans to shut down the network by 1998, Radiocom 2000 was given a one-and-a-half-year extension. The network finally closed on July 28, 2000, with the last subscribers being migrated to the GSM standard on the Itineris network.
Here's a brief timeline of Radiocom 2000's key milestones:
- 1988: 60,000 subscribers, 90% of phones installed in vehicles
- 1998: Planned shutdown date confirmed for December 31
- 1998: Shutdown date extended by one and a half years
- 2000: Network closed on July 28, subscribers migrated to GSM standard
How it Works
The Radiocom 2000 network operates on a frequency band of 400 MHz, using digital technology for signaling and analog modulation for voice.
It uses a dynamic frequency allocation system, assigning frequencies as needed to meet the growing demand of subscribers.
The network has expanded to use multiple frequency bands in certain regions, including the 200 MHz and 160 MHz bands in the IDF, Lyon, and Marseille areas, as well as the 175 MHz band in the north-east of France since 1990.
This expansion allowed for increased capacity and flexibility, enabling mobile devices to operate on both 400 and 900 MHz frequencies, a feature developed by Matra, Mobitel, and Sagem starting in 1990.

Van 2G naar 5G
In France, it all started with the first national mobile network, Radiocom 2000.
The next step was the rise of the fully connected world with 4G, the fourth generation of mobile telephony, which was fully rolled out around 2015.
Today, 5G is already impatiently waiting to take the next step, still in the research phase.
France was one of the first countries to launch a national mobile network, Radiocom 2000, marking the beginning of a new era in mobile communication.
The rollout of 4G around 2015 brought about a significant improvement in mobile internet speeds and connectivity.
5G is still in its research phase, but it's expected to bring even faster speeds and greater connectivity in the future.

Fonctionnement
The Radiocom 2000 network operates on a frequency band of 400 MHz, using digital technology for signaling and analog modulation for voice.
It attributes frequencies dynamically based on demand.
The network uses multiple frequency bands to meet growing demand.
In regions like IDF, Lyon, and Marseille, the 200 MHz and 160 MHz bands were used.
A 175 MHz band was also used in the north-eastern part of France for a specific subscription called Radiocom 2000 VHF A/B.
