Many BlackBerry users know that they can use the shortcut ALT+NMLL to show the signal strength of their BlackBerry in numbers instead of bars. On the other hand it does not look all that pretty. RIM was kind enough to offer a translation chart between the numbers and the bars on your BlackBerry in a current knowledge base article. Keep in mind that as the number goes further into the negative your signal strength is getting worse. This is because the better the signal the less power your BlackBerry has to use to send and receive data thus saving battery life.
| Signal Bar Strength Indicators | RSSI Indicators |
| 5 bars (optimal strength) | -77 or higher |
| 4 bars | -78 to 86 |
| 3 bars | -87 to -92 |
| 2 bars | -93 to -101 |
| 1 bar | -102 or lower |
The problem I still have is that these RSSI numbers are a vendor independent standard. Which means that they mean something different from each vendor compared to the standard dBm’s. Anybody found a way to convert them?
