L’éventail des nouvelles possibilités offertes par les téléphones mobiles n’est devenu possible que grâce aux énormes progrès technologiques que le secteur a connus ces dernières années. Des premiers appareils analogiques, la technologie a évolué vers la deuxième génération, les systèmes numériques, pour atteindre aujourd’hui le niveau 4.5G, la quatrième génération de téléphones mobiles. En réalité, l’évolution de la téléphonie mobile s’est déroulée selon différentes technologies en termes de qualité technique des opérations et de possibilités de services. Les systèmes numériques qui se sont imposés les premiers sur le marché sont l’AMRT, l’AMRC et le GSM. Enfin, la grande différence réside dans la disponibilité de nouvelles fonctions, qui font que le téléphone mobile n’est plus seulement un téléphone, mais un support électronique pour les actions les plus diverses.
