How to increase the power of the LoRa module

Power is one of the important parameters of the LoRa module. The greater the power of the LoRa module, the farther the transmission distance is, but the higher the relative power consumption. Today, NiceRF talk about how to increase the power of the LoRa module. In our usual projects, there will always be problems with insufficient transmission distance. Among them, increasing the power of the LoRa module is the best way to solve this problem. So NiceRF shares how the LoRa module increases power, hoping to help everyone.

Why increasing power can increase the transmission distance of LoRa modules

For example, in daily life, when we are engaged in dialogue, the greater the intensity of our speech, the longer the farther distance. If the other party is far away from us, we can make the sound go further and make it heard by shouting. The LoRa module increases the power and can make the distance transfer farther. This is also the reason.

How to increase the power of the LoRa module

1. Modify the value of the LoRa module register

The registers are part of the central processing unit and can be used to temporarily store instructions, data and addresses with a limited storage capacity of high-speed memory components. In the field of wireless communication, if we want to modify the power of the LoRa module, modifying the value of the register is undoubtedly the mostreliable method. The picture below is a example power settings (the outputpower corresponding to the register value of different modules is different, it is best to consult the manufacturer to set it again). NiceRF's old customers know that our data transmission module series can adjust the wireless module power through PC software. The actual principle is to change the power of the module by modifying the value of the register by PC software.

2. Add hardware amplifier device

In addition to software to modify the value of the register,we can also add power amplifier components in the hardware to increase the power of the LoRa module. However, this method is not recommended for everyone to use. The hardware circuit of the wireless module has been strictly designed by engineers. If a power amplifier is added in a situation that is notvery professional, it may cause damage to the hardware circuit of the module.
