LTE-M e NB-IoT s\u00e3o dois tipos de tecnologias celulares projetadas para aplica\u00e7\u00f5es de redes de longa dist\u00e2ncia de baixa pot\u00eancia (LPWAN), como dispositivos IoT. Elas apresentam algumas semelhan\u00e7as e diferen\u00e7as em termos de velocidade, largura de banda, cobertura, consumo de energia e complexidade. Aqui est\u00e1 um breve resumo das principais diferen\u00e7as:<\/p>\n\n\n\n

LTE-M vs NB-IoT<\/h2>\n\n\n\n

Velocidade<\/h3>\n\n\n\n

O LTE-M \u00e9 mais r\u00e1pido que o NB-IoT, oferecendo at\u00e9 1 Mbps de taxa de dados tanto no downlink quanto no uplink para redes 4G, e at\u00e9 4 Mbps para redes 5G. Por outro lado, o NB-IoT pode atingir apenas 26 kbps no downlink e no uplink para redes 4G e at\u00e9 127 kbps para redes 5G.<\/p>\n\n\n\n

Largura de banda<\/h3>\n\n\n\n

O LTE-M utiliza uma largura de banda de 1,4 MHz, a mesma de um bloco de recursos LTE t\u00edpico. O NB-IoT utiliza uma largura de banda mais estreita, de 200 kHz, equivalente a um bloco de recursos f\u00edsicos dentro de um bloco de recursos LTE t\u00edpico. Isso significa que o NB-IoT pode acomodar mais dispositivos no mesmo espectro e tem menor capacidade de dados e velocidade.<\/p>\n\n\n\n

Cobertura<\/h3>\n\n\n\n

Ambos LTE-M<\/a> e NB-IoT<\/a> Possuem melhor cobertura do que dispositivos LTE convencionais, especialmente em \u00e1reas internas e rurais. Podem utilizar t\u00e9cnicas como repeti\u00e7\u00e3o e adapta\u00e7\u00e3o de enlace para melhorar a qualidade e a confiabilidade do sinal. Tamb\u00e9m suportam o modo de aprimoramento de cobertura (CEM), que permite transmitir em n\u00edveis de pot\u00eancia mais altos e receber em n\u00edveis de sinal mais baixos. No entanto, algumas fontes afirmam que o NB-IoT tem uma ligeira vantagem sobre o LTE-M em termos de perda m\u00e1xima de acoplamento (MCL), que mede a perda m\u00e1xima no n\u00edvel de pot\u00eancia conduzida que um sistema pode tolerar e ainda permanecer operacional. De acordo com 3GPP<\/a> De acordo com os padr\u00f5es, o MCL para NB-IoT \u00e9 de 164 dB, enquanto o MCL para LTE-M \u00e9 de 160,7 dB para redes 4G e 164 dB para redes 5G. No entanto, outras fontes argumentam que essa diferen\u00e7a n\u00e3o \u00e9 significativa e que o LTE-M pode atingir a mesma ou melhor cobertura que o NB-IoT com a configura\u00e7\u00e3o adequada.<\/p>\n\n\n\n
