1G, 2G, 2.5G … A telefonia móvel de primeira geração ou 1G são

analógicos, já que enviam a informação sobre ondas cuja forma varia de forma continua.

A telefonia móvel de segunda geração (2G) não é um padrão ou um protocolo estabelecido, é uma forma de nomear a mudança de protocolos de telefonia móvel analógica para digital.

2,5G é a segunda e meia geração de padrões e tecnologias de telefonia móvel. É considerada o degrau de transição entre as tecnologias 2G e 3G, embora o termo "2,5G" tenha sido definido pela mídia, e não oficialmente pela União Internacional de Telecomunicações (UIT).

3G, 4G ! 3G é a terceira geração de padrões e tecnologias de

COMUNICAÇÃO móvel, substituindo o 2G. É baseado na família de normas da União Internacional de Telecomunicações (UIT), no âmbito do Programa Internacional de Telecomunicações Móveis (IMT-2000).

A 4G estará baseada totalmente em IP sendo um sistema de sistemas e uma rede de redes, alcançando a convergência entre as redes de cabo e sem fio assim como computadores, dispositivos eletrônicos e tecnologias da informação para prover velocidades de acesso entre 100 Mbps em movimento e 5 Gbps em repouso, mantendo uma qualidade de serviço (QoS) de ponta a ponta (ponto-a-ponto) de alta segurança para permitir oferecer serviços de qualquer tipo, a qualquer momento e em qualquer lugar.
