Item:Q4561
wbsetclaim-create:2||1: quote (P203): With bluetooth you can keep track of who has been within radio range. Range is not the same as distance. Range is determined by the transmitting power, the reception sensitivity, the distance (yes) and the environment (walls, obstacles, reflectors, etc.). Out of range you can deduce the distance, but this is not very accurate.

Item:Q4528
wbsetclaim-update:2||1: comment (P126): The signal strength reduces with distance: the further the sender, the weaker the signal — until it is no longer detected. IN THEORY, if one knows the transmission power of the source, one should be able to compute the distance between the sender and the receiver from the inverse square law.

Item:Q4560
wbsetclaim-create:2||1: quote (P203): RSSI biases caused by both the sending and receiving device have to be calibrated out. When working with iBeacons, we have noticed that, even if the sending device is the same (a fixed iBeacon), different devices observe very different RSSI patterns. Differences of 20 dBm (= 100x signal strength difference) are not unusual.

wbsetclaim-update:2||1: quote (P203): The RSSI also vary wildly depending on: |Sending device model Receiving device model | The geometry of the building |The location of the devices within the building | Number of people nearby | Whether the device is in the pocket or held in hand | The direction the person with the phone is facing |The signals bleed through floors — probably unlike the virus.

Ils alertent sur les dérives possibles, sur les limites techniques et sur l’entrée à bas bruit dans une société de contrôle.
