What Do the 4 Bars Represent?
The 4 bars you see next to your WiFi indicator are a representation of your device’s WiFi signal strength. They’re often accompanied by a series of abbreviations like “RSSI” or “dBm,” which can be confusing for the average user. So, what do these bars really represent?
The 4 bars are a visual representation of the Received Signal Strength Indication (RSSI), which is the measure of the power present in a received radio signal. In simpler terms, it’s a way to measure how strong or weak your WiFi signal is. The more bars you see, the stronger the signal.
What is RSSI?
RSSI is a unit of measurement that’s used to quantify the power of a radio signal. It’s usually measured in decibels (dB) and ranges from -100 dB to 0 dB. The closer you are to 0 dB, the stronger your signal. Here’s a rough breakdown of what the RSSI values mean:
- -50 dB to 0 dB: Excellent signal strength, perfect for streaming and heavy internet use.
- -60 dB to -50 dB: Good signal strength, suitable for browsing and general internet use.
- -70 dB to -60 dB: Fair signal strength, may experience some buffering or lag.
- -80 dB to -70 dB: Poor signal strength, may struggle to maintain a connection.
- -90 dB to -80 dB: Very poor signal strength, almost impossible to maintain a connection.
How Do the 4 Bars Translate to RSSI?
Now that we know what RSSI is, let’s see how it relates to the 4 bars on your WiFi indicator. The translation isn’t always straightforward, as different devices and manufacturers may use different scales. However, here’s a general guideline:
| Number of Bars | RSSI Range |
|---|---|
| 4 Bars | -50 dB to 0 dB |
| 3 Bars | -60 dB to -50 dB |
| 2 Bars | -70 dB to -60 dB |
| 1 Bar | -80 dB to -70 dB |
| No Bars | -90 dB to -80 dB |
Keep in mind that these are rough estimates, and the actual RSSI values may vary depending on your device and manufacturer.
Why Do the 4 Bars Sometimes Misrepresent the Actual Signal Strength?
