What is a cellular network?
To put it simply, cellular network and mobile network refer to the same thing, just with different names. It is a mobile communication hardware architecture. It is named because the signal coverage of each communication base station that forms the network coverage is hexagonal, making the entire network resemble a honeycomb.
Currently, the world’s mainstream cellular network types include: GSM in the 2G era, WCDMA/CDMA2000 in the 3G era, and LTE/LTE-A in the 4G era. Usually, a cellular network mainly consists of three parts: mobile station, base station subsystem, and network subsystem.
Some characteristics of cellular networks form part of the basis for the development of mobile communications. For example, frequency reuse: it allows limited frequency resources to be reused within a certain range. Another example is cell splitting: when capacity is insufficient, the coverage of a single “cell” can be reduced and a larger number of “cells” can be divided, thereby further improving frequency utilization efficiency.
O que é a IoT celular?
Cellular IoT uses existing cellular networks to connect IoT devices. It is a way to connect physical devices to the Internet. Cellular networks that facilitate the flow of massive amounts of data are now available around the world, so we don’t need to build any new physical infrastructure to support cellular IoT. Through cellular IoT, people connect some physical devices (such as sensors) to smartphones or computers on the same cellular network. Its infrastructure simplicity, coupled with the emergence of 5G, makes cellular IoT a strong player in the connectivity space.
We already see the value of being connected to the physical objects around us: the street lights, parking meter systems and hospitals that occupy our daily urban lives, or the countless industrial applications such as manufacturing and agriculture that can take advantage of cellular IoT Strengthen connections.
It is predicted that by 2023, the number of devices connected to more than 20 deployed mobile IoT devices will grow at an annual rate of 19%. In other words, the total number of connected IoT devices is expected to reach more than 20 billion in 2023. Specifically, the number of IoT devices accessed through LTE and 5G will reach more than 3.5 billion, mainly distributed in China and Greater Northeast Asia area.
5G and the future of cellular IoT
5G is essentially the same as all other “G” cellular Internets; but 5G is ready to change the landscape of IoT because it’s better, faster, and stronger.
When it comes to industrial IoT, ultra-secure private 5G networks will be able to facilitate thousands of devices in manufacturing or logistics environments, operating at 10 times the speed of existing networks. On the consumer side, 5G could unlock the data floodgates necessary to make self-driving cars or immersive virtual reality and AR environments a reality.
5G is a perfect enabler for IoT due to its high data speeds, low latency, greater flexibility, low energy consumption, cost-effectiveness and ability to support more devices. 5G will play an important role not only in changing the way we communicate, but also in businesses and society as a whole.
