In the era of the Internet of Things, is it a wise decision for the three major operators to shut down 2G base stations on a large scale?
has a large number of functions such as positioning and card swiping. Because the interactive data with the server is single, a positioning information is uploaded and a lock-opening command is issued. The data volume is less than 1K, and the 2G network can fully meet the needs. The coverage radius of
2G base station is about 5-10 kilometers. The coverage radius of
3G base station is about 2-5 kilometers.
4G The coverage radius of 1-3 kilometers.
5G base station is about 100-300 meters. In comparison, 4G has a narrow coverage of 5G base station and high operation and maintenance costs. The 2G network base station is large in scale and has a wide coverage.
can be deployed on the Internet of Things as long as there is a 2G mobile phone signal, which far exceeds the stability and coverage of wireless solutions such as WiFi, Bluetooth .
and also have obvious advantages in the hardware cost of IoT product development and manufacturing. A 2G module costs only 20-30 yuan, while 3G and 4G modules cost at least 100 yuan, and the 2G communication fee is also cheaper.
together considers it, 2G communication should of course be the first choice in the field of outdoor IoT, and is more popular among companies that need to deploy IoT devices in large quantities, such as industry, electricity, manufacturing, etc.
However, at this turning point in the era when the Internet of Things is about to leap, the three major operators chose to clear out 2G base stations on a large scale because the 2G business cannot bring more profits. Is this a reverse of history? Is this a wrong decision?
