2000 is the French mobile network launched in 1986, which gradually
replaced the analog network "public correspondence". It is classified in the first generation of mobile category (1G).
Running on the 400 MHz frequency band, the network uses digital technology for signaling and analog modulation for voice. The frequencies are allocated dynamically as needed.
with the growing demand of subscribers, several frequency bands are
used on Radiocom 2000 network bands including 200 MHz and 160 MHz on the
IDF regions, Lyon and Marseille as well as the 175 MHz band (specific
subscription called "Radiocom 2000 VHF A / B ") in 1990 in the north-east quarter of France. Always
to meet the demand for more capacity, from 1990 mobiles have become
400/900 MHz dual band, developed by Matra, Mobitel and Sagem as
builders. Other brands have released these products to their respective brands (OEM) Original Equipment Manufacturer, Alcatel and Nokia.
Radiocom 2000 appeared the first cell phone with notions, shortly after
its launch, the appearance of handover called "High Density Network"
RHD (ability to dynamically change cell) and the allocation of
frequencies within a cell. The network covers almost the entire territory. The proposed subscriptions could be regional: Island of France, Lyon Region, PACA, Province and National.
The posts are manufactured by Matra, Radiotel, Alcatel and Sagem. The Nickel-Cadmium batteries are rechargeable. The
antenna is smaller than that of a terminal 1980, but the terminal
remains bulky and prohibitively expensive (+ subscription unit). It is deployed by France Telecom Mobiles.
In 1988, it has 60,000 subscribers and more than 90% of devices are installed in vehicles. That
same year, the competition appears with the birth of the French Society
for radio (SFR), combining the General Water Company (41%), Credit
Lyonnais (19%), the Joint Shipping Company (8.6%) TDF (7.5%), Banexi (4%), Bell South (4%) and Racal (4%), using the standard NMT-F (Nordic Mobile Telephone "French"). Abandonment for the exclusive benefit of the standard GSM on 28 July 2000. https://fr.wikipedia.org/wiki/Radiocom_2000
