Is dBm a good WIFI signal?
Wireless signal strength is measured in dBm (decibel milliwatts) and is, somewhat confusingly, expressed only as negative values. … Anything down to this level can be considered excellent signal strength. -60 dBm. Good, reliable signal strength.
Is higher or lower dBm better?
Strong signal strength results in more reliable connections and higher speeds. Signal strength is represented in -dBm format (0 to -100). This is the power ratio in decibels (dB) of the measured power referenced to one milliwatt. The closer the value is to 0, the stronger the signal.

What blocks a WiFi signal?
Concrete, with and without metal reinforcement, is one of the worst building materials for wireless signals to pass through, but masonry block and bricks can also be serious barriers for Wi-Fi.
Is dBm good or bad?
-80 to -89 dBm, then it’s generally considered good signal (3 to 4 bars). -90 to -99 dBm, then it’s generally considered average signal (2 to 3 bars). -100 to -109 dBm, then it’s generally considered poor signal (1 to 2 bars). -110 to -120 dBm, then it’s generally considered very poor signal (0 to 1 bar).
How much dBm is dangerous?
Phone signal strength shows -51 dBm and 31 asu. I’ve been looking into this for a while and I have not seen levels this high anywhere else. Thinking somewhere above -65 it gets too excellent and it becomes dangerous, especially on the long term.
What is the maximum range of WiFi?
A general rule of thumb in home networking says that Wi-Fi routers operating on the traditional 2.4 GHz band reach up to 150 feet (46 m) indoors and 300 feet (92 m) outdoors. Older 802.11a routers that ran on 5 GHz bands reached approximately one-third of these distances.
