With the continuous development and popularization of IoT technology, connectivity has become one of the most important indicators of the strengths and weaknesses of IoT systems. And NB-IoT technology, as a low-power wide area network IoT technology, its connectivity has been attracting attention. So, how many IoT devices does NB-IoT technology support maximum connection?
First of all, it should be clear that NB-IoT technology is a kind of narrowband IoT technology, and its supported connection methods include narrowband IoT, Cat-M and 4G cellular data. Among them, narrowband IoT supports up to 500,000 connections and 4G cellular data supports up to 2 million connections. Cat-M, on the other hand, sits somewhere in between, supporting a maximum of up to 1 million IoT device connections.
However, these numbers are only the theoretical maximum number of connections, and are actually governed by a number of factors. For example, the type, configuration, and bandwidth size of the network device, as well as the access method and transmission frequency of the IoT device, all affect the number of connections. This is why, in practice, the number of connected devices supported by NB-IoT technology tends to vary on a case-by-case basis.
In addition to the number of connections, the radius of support of NB-IoT technology is also one of the indicators of its strengths and weaknesses. According to statistics, the maximum coverage radius of NB-IoT technology in non-dense urban areas can reach more than 10 kilometers, while in dense urban areas it is 2-3 kilometers. This also provides a great feasibility for practical use scenarios of IoT applications.
In summary, the maximum number of IoT devices supported by NB-IoT technology to connect has a certain theoretical basis, but it will be constrained by a variety of factors in practical applications. Therefore, when determining the application of NB-IoT technology, it needs to be evaluated according to specific scenarios and reasonably planned in conjunction with actual needs.
