The difference between 2G module and 4G module, the competition between communication speed and application scope

In recent years, with the continuous development of Internet of Things technology, wireless communication modules have also been widely used. Among wireless communication modules, 2G modules and 4G modules can be said to be the two mainstream technologies. This article will introduce the differences between 2G modules and 4G modules, focusing on communication speed and application scope.

The difference between 2G module and 4G module

Communication speed is one of the important indicators to measure the performance of wireless communication modules. The 2G module uses the second generation mobile communication technology, and its theoretical transmission rate can reach tens of kbps, which is lower than the hundreds of Mbps of the 4G module. In practical applications, this means that the 2G module has low data transmission efficiency and is suitable for some application scenarios that do not require high communication speed, such as simple text message transmission, tracking and positioning, etc. For applications with large amounts of data and high communication speed requirements, 4G modules can provide better support, such as high-definition video transmission, remote monitoring, etc.

In addition to communication speed, there are also certain differences in the application scope of 2G modules and 4G modules. 2G modules are widely used in low-power devices in the Internet of Things, such as sensor nodes, smart homes, etc. It has the characteristics of low power consumption, low cost and long battery life, and is very suitable for application scenarios with high power and cost requirements. The 4G module is mainly used in high-end smart devices and mobile communication devices, such as smartphones, tablets, etc. The high-speed transmission and powerful processing capabilities of 4G modules enable these devices to implement more functions and provide a better user experience.

To sum up, there are significant differences in communication speed and application scope between 2G modules and 4G modules. The 2G module is suitable for application scenarios that have low communication speed requirements and high power and cost requirements, while the 4G module is suitable for application scenarios that have high communication speed requirements and many functional requirements. When selecting a wireless communication module, you need to weigh these differences based on specific application requirements and select the most appropriate module to meet the needs.
