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).

2G mobile networks were voice centric MSC SMSC BSC HLR 6300 6300 • Voice centric services • Few services beyond Voice and SMS • Simple mobile devices • Devices geared towards voice, text-messaging and ringtones • No real OS, no way to program the phone • TDM backhaul • Traffic backhauled using dedicated/leased circuits or SDH • 5500 & 6300 GSM CDMA PSTN OCn n x DS3 / OCn n x DS3 SDH 5500 Voice Core TDM Backhaul BTS
2.5G added a data overlay to a voice-centric architecture BSC / RNC MSC SMSC HLR 6300 6300 App Servers • New Packet Data Services • Introduction of new Packet Switched Data Core with Gateway nodes (SGSN/GGSN) modeled as “data MSC” • First generation of Smartphones and PDAs • WAP based Internet access • Emergence of Blackberry for Enterprise email • Some multimedia capabilities (e.g., MMS) but no application download capability • Increasing traffic load on the backhaul network PSTN OCn n x DS3 / OCn n x DS3 CS Voice Core SDH 5500 TDM Backhaul BTS Internet GPRS/EDGE/1xRTT PS Data Core SGSN / PDSN GGSN / Home Agent
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.
3G adds data capacity thus increasing backhaul traffic MSC SMSC HLR 86xx App Servers 8800/86xx • Mobile Internet arrives • WAP based Internet apps mature into Browser based Internet access • Increased data traffic with corporate email service • Multimedia Smartphones • Multimedia capable devices with cameras, music, video and ringtones • Still no app downloads • Pseudowire backhaul • Migration to a more cost-effective packet transport to keep up with backhaul capacity demand • 8600 and 8800 PSTN UMTS/HSPA/EVDO CS Voice Core Pseudo-Wire Backhaul RNC NodeB 86xx Internet PS Data Core SGSN / PDSN GGSN / Home Agent

“Over-the-Top” Internet applications are stressing the network • “Over-the-Top” model • Applications delivered on a “best effort” basis • Service Providers are only able to monetize subscriber access • Over-the-Top apps unable to deliver good quality-of-experience to end users • Application performance deteriorates as usage grows • Application proliferation opens up threats from malware, viruses, and worms Service Provider Subs Application Providers Access $$ “Best Effort” Over-the-Top
