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.
