Average WiFi Transmit Power: Separating Fact from Fiction

When it comes to improving your Wi-Fi network's coverage and speed, one common suggestion is to increase the transmission power on your router. However, the relationship between a specific Wi-Fi access point's transmit power and the accompanying user experience is not as straightforward as it seems.

Different routers provide varying settings for adjusting transmit power. Some devices offer an absolute setting matching the radio's milliwatt output, typically measured in decibel milliwatts (dBm), while others have a relative power option, allowing you to adjust the transmit power from 0% to 100%. Some routers may even have only three options: low, medium, and high.

Manufacturers differ in how they display and adjust transmit power. If your router supports transmit power changes, you can usually increase the power output by turning up or down the volume on the setup panel. Just as sound energy is measured in decibels (dB), Wi-Fi radio energy is also measured in dBm. The transmit power of your Wi-Fi router is analogous to a stereo's volume knob.

While there is certainly more to learn about radio transmission power, we'll keep our focus on the practical aspects for everyday use. For instance, if you're experiencing trouble getting adequate Wi-Fi coverage at home, it may seem logical to increase the transmit power of your router. However, this solution is not always the most effective.

In summary, average WiFi transmit power does not necessarily imply better coverage or speed. It's essential to understand the specific settings and limitations of your router to optimize its performance for your unique needs.
