You won’t notice significant differences in quality if you’re at -40 relative to -30 (even though -40 is lower). In the chart above, there are three main RSSI performance score regions. Example: RSSI = -30 is better than RSSI = -60. In the context of Ring, the closer the value is to 0 the better. In general, a higher RSSI is always better than a lower RSSI. Objects, walls and other barriers between the router and Ring result in lower received signal strength.The distance between the Wi-Fi router and Ring – the greater the distance the lower the signal.Use this calculator to convert from dB to a linear value. So if your RSSI yesterday was -70 dBm and today it’s -50 dBm, you could say that it improved by the difference or by 20 dB. dB can be used to indicate the difference between two numbers. Use this calculator to convert from dBm to Watt.ĭB on the other hand, is a relative number and has no units. You cannot convert from one to the other.ĭBm stands for dB relative to one milliwatt. Although people sometimes confuse the two and use dB and dBm interchangeably. Ideally you want to position the Ring doorbell such that the RSSI level greater than -50 dBm. The scale is split into three main regions. The table below shows how they are related. Use the value of RSSI computed above to understand the quality of the signal. It also accounts for walls or floors that are in between. It provides an estimate based on distance of the Ring device from the Wi-Fi router.
