Radio TX Power vs Advertised TX Power
Radio TX Power is the strength of the transmitted signal (in dBm). For our beacons it goes from -40 to +4 dBm. The Radio TX Power impacts on the transmission distance: the higher the Radio TX Power, the longer the distance.
The Advertised TX Power is the Calibrated RSSI (Received Signal Strength Indicator), i.e. the received power measured at a reference distance, that is 0 mt for Eddystone and 1 mt for iBeacon packets. By default, the Calibrated RSSI is automatically scaled when Radio TX power is modified, so that the proximity estimation is not impacted.
Beacon Calibrated RSSI value
The Beacons have a default calibrated RSSI set to -54dBm. To this value, the Advertising Frame Power has to be added. For example, if the Advertising Power is set to -8dBm, the total power will be -62dBm. Or if the Advertising Power is +4dBm, the ...
BlueUp Beacons Configuration
BlueBeacon beacons are shipped with the following default settings: Slot 1, 2, 3, 4: Not Configured (i.e. not enabled). Slot 5: iBeacon (UUID = ACFD065E-C3C0-11E3-9BBE-1A514932AC01, major = 0, minor = S/N, ADV interval = 400 msec, TX power = -8dBm). ...
What is a beacon
A beacon is an intentionally conspicuous device designed to attract attention to a specific location. A classical example of beacon is the lighthouse, used in navigation, that helps navigators find their destination. In electronics, a beacon is a ...
Advertising Frames Configuration
It is possible to configure up to 8 slots for non-connectable (ADV_NONCONN_IND) advertising frames, with the following properties: 4 slots are dedicated to Eddystone frames, and can be configured as URL, UID, TLM and/or EID (with more slots ...
Beacons ranging accuracy
Ranging with beacons is based on the value of RSSI (Received Signal Strength Indicator), i.e., the value of the RF signal received by your smartphone. The received signal is strongly affected by several parameters, such as the relative orientation ...
