It was with Radiocom 2000 that the first concepts of cellular telephony appeared with, shortly after its launch, the appearance of the handover called "High Density Network" (capacity to change cells dynamically) and the allocation of frequencies within a cell.

That same year, competition appeared with the birth of the Société française de radiotéléphones (SFR), using the NMT-F (Nordic Mobile Telephone "French") standard.
The last subscribers to the Radiocom 2000 system were then offered a switch to the new GSM standard, on the Itinéris network of France Télécom.
