In your home, your Wi-Fi network might use several Wi-Fi access points (BSSIDs). For example, if you have mesh extenders to improve your Wi-Fi coverage, each mesh extender is a Wi-Fi access point.
In order to ensure a smooth deployment of Wi-Fi sensing devices, nami put in place a mechanism to impose a common BSSID to all the devices of a zone. This is necessary for all the devices in the zone to be able to exchange Wi-Fi frames and for the sensing mesh of the zone to be healthy. Without this mechanism, the sensing performances would be degraded.
This has consequences on the optimal placement of your devices in a zone. In the area you intend to cover, do make sure that there is a single Wi-Fi access point covering well the entire area. All the devices in that zone will be attached to this access point and can not be too far from it.
How is the BSSID chosen for a zone?
During the setup, the first device of the zone will be the one choosing the BSSID. At the Wi-Fi scanning step, it will look around at all the accessible BSSIDs and select the one with the best RSSI value. In the example above, the extender is chosen.
Once chosen, this BSSID is used by all the devices setup in the zone. Make sure that they are in a reasonable distance from the pined access point. Once the devices setup are complete, you can go check the RSSI value of the connexion between the device and the access point. If it is below -70dB, we recommend moving the device closer to the access point.
