¿Se puede utilizar el módulo 4G sin antena? Más información

Can the 4G module be used without an antenna? This is an issue that many people are concerned about recently. In fact, the 4G module can be used without an antenna , but it will be affected by the signal quality and may cause problems such as signal instability and slow speed. So, why can the 4G module still be used without an antenna?

First, we know that the antenna is a device used to receive and send signals. Without the antenna, the 4G module cannot send and receive signals normally. However, today’s 4G modules are usually designed with built-in antennas, so they can be used even without external antennas.

Second, the receiving capacity and range of the built-in antenna are relatively small and are easily blocked and interfered, so the signal may be unstable during use.

Third, the coverage and signal strength of 4G signals are also important factors that affect the use effect. If used in an area with good signal coverage, the experience of using the 4G module without an antenna may be better.

Fourth, if the user does not connect the antenna when using the 4G module, he or she needs to consider the surrounding signal environment and usage requirements in order to choose the appropriate usage method.

All in all, the 4G module can be used without an antenna, but the signal quality may be affected to a certain extent. If the user needs a more stable and faster signal experience, it is recommended to connect the antenna during use. Hopefully this article will help readers better understand this issue.
