You won’t notice significant differences in quality if you’re at -40 relative to -30 (even though -40 is lower). However as shown in the chart above, there are three main RSSI performance score regions. 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.

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.

dBm is an absolute number – just like Watt and in fact you can calculate one from the other.ĭB on the other hand, is a relative number and has no units. It will give you an estimate of what you can expect based on distance from the Wi-Fi router and walls or floors that are in between. Note This method has been removed from versions of impOS running on the impC001.A Ring doorbell has a range of around 160 feet or less. If the WiFi is not active at all, or during an outage, the result will be zero. Remember, the value can change even if both the imp and the WiFi access point or router are not moved and remain at constant range. There are many more signal strength levels above -67 - values of up to -11 have been reported - but that’s not important: anything above -67 is good enough for everything the imp needs to do. To convert the value to ‘bars’ of signal strength as seen on phones, tablets and laptops, one mapping might be: RSSI

The figure returned is the raw value reported by the WiFi hardware. the closer to zero), the greater the signal strength. The current strength of the WiFi signal in dBm is negative, and the higher the number (ie. The recommended means of gaining the information this method returns is to call (). However, removing it altogether would cause users’ existing code to stop working, so we currently have no plans to do so.
