How to enhance the signal strength of the wireless module?

By sdga:NiceRF Wireless Technology Co., Ltd

Recently, a user asked online, how can the wireless module enhance the signal strength? First of all, let us first understand what the signal is? The signal is a necessary factor for the wireless module to generate communication, and all data is transmitted by the signal. What is the use of enhancing the signal strength of the wireless module? One is to make the transmission distance of the wireless module farther. The second is that the working environment of the wireless module has a strong source of interference. Only when the signal strength is increased can normal communication be performed.

How to enhance the signal strength of the wireless module?

So how does the wireless module enhance the signal strength?

1. Use a high-gain antenna

The antenna can play a role in enhancing the radiation range of the signal, so that the signal can be transmitted to a farther place; so the choice of using a high-gain antenna is effective to enhance the signal strength of the wireless module. How to judge whether the antenna gain is higher? Check the antenna's standing wave ratio. The larger the standing wave ratio, the greater the radiation range. (The placement of the antenna is also very important. The higher the height of the antenna from the ground, the better the gain effect)

2. Add power amplifier

The size of the power determines the strength of the signal, so if you want to enhance the signal strength of the wireless module, you can add a power amplifier to the hardware. However, this method is not recommended for everyone, because the circuit design of each wireless module is strictly designed. In unprofessional situations, adding a power amplifier is easy to cause damage to the circuit. It is recommended to communicate with the manufacturer before Take the next step.

These two methods of enhancing signal strength are also given by NiceRF hardware engineers. Currently, there are only two methods for effectively enhancing the signal strength of wireless modules. If you have a better method or suggestion, please feel free to contact us to communicate.
