DD-WRT equipment can help us to achieve any adjustment of the purpose of the transmit power, so that we can be based on the wireless network card distance from the DD-WRT wireless router to determine the strength of the transmit signal. Below we speak with the facts, step by step teach readers how to adjust the transmit signal power in the DD-WRT equipment, and compare the received effect before and after the adjustment.
I. Default reception results:
We turn on the DD-WRT wireless device, wi

Question: You must know that not only beginners can make mistakes. (The best saying of shiroki)
Some interesting problems have been found recently, so it is worth a bit of memo.
Let's take a look at the code section:

Mobile phones have been proved to be quite radiant. Long-term use may endanger our health. Many people have noticed this problem. Wireless networks also have radiation, so how can we prevent it?
Radiation is harmful to the elderly, children, and pregnant women
During the use of wireless networks, wireless routers, Wireless AP and other devices emit electric waves all the time. High-dose electromagnetic radiation will affect and damage the original biological current and biological magnetic field
Android system transplantation and debugging -------) how to modify the number of 4G signal strength grids displayed on Android phones
Before modifying the displayed signal strength, let's take a look at what is dB and what is dBm?
1. dBDB is a value that represents relative values. A pure ratio represents only the relative size relationship between two quantities, with no unit, when considering the number of dB whose power is larger or smaller than that of B,
The formula below is as follows: 10
With the development of the routing industry, the problem of router radiation is becoming increasingly apparent. Some friends may have questions about vro radiation when using Dlink wireless products. In fact, you don't have to worry too much. I will give a brief introduction below:
In fact, to sum up one sentence: How can you safely use GSM, CDMA, or PHS mobile phones, then you can use wireless devices with greater peace of mind, this is because the radiation from the above devices to the huma
