Enquanto lhe falamos do serviço IoT e dos produtos que temos para si surgiu o conceito “rede NB–IoT” lembra-se? Neste tópico vamos contar-lhe mais sobre esta rede. :sunglasses:

A NOS, pioneira na implementação da tecnologia Narrow Band IoT (NB-IoT) em Portugal, para além de assegurar uma melhor experiência com equipamentos conectados, permite ainda uma otimização do consumo da bateria dos dispositivos, podendo em alguns casos garantir vários meses sem necessidade de recarga.

 

Mas afinal, o que é o NB-IoT?

O NB-IoT (Narrow Band Internet of Things) é uma tecnologia de conectividade que permite obter um elevado número dispositivos e sensores ligados, sem interferências e com maior cobertura. Esta tecnologia permite, ainda, uma otimização do consumo da bateria dos dispositivos, podendo em alguns casos garantir vários sem que precisem de ser recarregados.

 

Esta tecnologia é bastante benéfica pois acompanha a evolução dos objetos inteligentes, ou seja, com a recorrência da sua utilização é necessário responder com um meio de conetividade para mais dispositivos e, por sua vez, com melhor cobertura.

 

É com os tarifários NOS IoT que pode fazer toda a gestão da conectividade através da App NOS, na qual recebe alertas e comunicações de serviço, carrega o saldo ou pagar faturas, entre outras funcionalidades. :hugging:

Uma evolução incrível. Gostou da novidade? Partilhe connosco.

@andrew.rozhkov hi!

What kind of equipment is this?  I didn't perceive.  What do you do specifically?

@DalleyBorges Hello,

This is an access control module that enables door opening, for instance, at home, using a mobile phone. It employs NB-IoT technology to synchronize keys between the access control device and the cloud.

Hello @andrew.rozhkov,

Thank you for your feedback.

The NOS NB-IoT service is destined to be used in alarms, locators or smartwatches.
From what we understand the device you’re using is oriented towards software development, right? 

Thank you

Hello @João H. 

 

NB-IoT is a transport protocol, one among the many existing LPWAN protocols. Imagine providing a service akin to WiFi, which is also a transport protocol enabling device connectivity to the internet, much like what NB-IoT does. However, it restricts usage to only tablets, prohibiting mobile phones from accessing the same services, such as sending emails or watching videos. Doesn't that seem odd?

Similarly, consider Ethernet, which only allows connection for a specific group of devices like alarms or locators, but not for regular PCs.

It appears that NOS has promised certain functionalities but is unable to deliver them to clients.

yup, its locked for most stuff, every thing explained here and in the nos website » https://www.nos.pt/movel/iot#mais

as u can see they sell it for those 3 purposes the moderator was telling about

I guess maybe for what ur looking for, the best option would be a regular mobile data simcard, no? 

um bem haja

Yes, it's a common scenario with advertisements; always pay attention to the fine print :)

Indeed, NB-IoT offers several benefits that I'm keen to utilize. Typically, the cost for one SIM card per month is about 1 euro, and it provides reliable connectivity to the network, even in basements.

P.S. The specific SIM card used doesn't matter as much as the equipment it's used in :)

Já alguem conseguiu colocar um SIM7020 ou SIM7028 a funcionar com os cartões NB IoT da NOS?
