\"Diferen\u00e7a<\/p>\n

\n

Principal diferen\u00e7a<\/h2>\n

GSM (Global System for mobile) e WCDMA (Wideband Code Division Multiple Access) s\u00e3o dois tipos de tecnologias sem fio ou tecnologias de sistema de r\u00e1dio. A maioria das pessoas est\u00e1 familiarizada com o GSM, mas poucos conhecem o WCDMA. A principal diferen\u00e7a entre GSM e WCDMA \u00e9 que GSM \u00e9 uma tecnologia 2G enquanto WCDMA \u00e9 uma tecnologia 3G.<\/p>\n

O que \u00e9 GSM?<\/h2>\n

GSM significa Global System for Mobile que descreve o protocolo para redes celulares digitais 2G (2\u00aa gera\u00e7\u00e3o) usadas por telefones celulares. \u00c9 o padr\u00e3o global padr\u00e3o para comunica\u00e7\u00f5es m\u00f3veis desde 2014. Hoje, 76% da participa\u00e7\u00e3o de mercado \u00e9 de propriedade da GSM e opera em mais de 219 pa\u00edses ao redor do mundo. A rede 2G substituiu as redes celulares anal\u00f3gicas 1G e, depois disso, o GSM entrou no campo que originalmente descrevia uma rede digital comutada por circuito que \u00e9 otimizada para telefonia de voz full-duplex. GSM \u00e9 de propriedade integral da GSM Association e GSM \u00e9 a marca registrada da empresa.<\/p>\n

O que \u00e9 WCDMA?<\/h2>\n

WCDMA significa Acesso M\u00faltiplo por Divis\u00e3o de C\u00f3digo de Banda Larga, que descreve o protocolo para redes celulares digitais 3G usadas por telefones celulares. \u00c9 um padr\u00e3o de interface a\u00e9rea encontrado em redes de telecomunica\u00e7\u00f5es m\u00f3veis 3G. Al\u00e9m dos servi\u00e7os celulares normais, como chamadas de voz e \u00e1udio, MMS e servi\u00e7o de texto, ele transfere dados em alta velocidade, resultando na entrega de aplicativos de maior largura de banda, incluindo streaming e acesso \u00e0 Internet de alta velocidade. Ele usa a mesma rede central que as redes 2G GSM usadas globalmente, permitindo opera\u00e7\u00e3o m\u00f3vel de modo duplo ao lado de GSM\/EDGE.<\/p>\n

Principais diferen\u00e7as<\/h2>\n
    \n
  1. GSM \u00e9 usado em todo o mundo, enquanto WCDMA \u00e9 usado apenas nos EUA.<\/li>\n
  2. GSM tem uma participa\u00e7\u00e3o de mercado de 76% enquanto WCDMA est\u00e1 em fase de progresso.<\/li>\n
  3. O WCDMA \u00e9 mais avan\u00e7ado e cont\u00e9m mais recursos em compara\u00e7\u00e3o ao GSM.<\/li>\n
  4. A velocidade e o desempenho do WCDMA s\u00e3o muito maiores do que o GSM.<\/li>\n
  5. GSM usa tecnologias GPRS \/ E \/ 4G \/ LTE para transfer\u00eancia de dados. O WCDMA usa o m\u00e9todo de acesso ao canal DS-CDMA e o m\u00e9todo de duplexa\u00e7\u00e3o FDD para obter maior velocidade.<\/li>\n
  6. GSM \u00e9 uma tecnologia 2G, enquanto WCDMA \u00e9 uma tecnologia 3G.<\/li>\n
  7. O tamanho da portadora do WCDMA \u00e9 5 MHz CDMA, enquanto o do GSM \u00e9 200 kHz TDMA.<\/li>\n
  8. WCDMA suporta downlink que favorece a diversidade de transmiss\u00e3o. GSM n\u00e3o suporta isso.<\/li>\n<\/ol>\n
