Example of proper positioning of the mobile beacon can be found here:
-
The beacon is placed horizontally and above other objects that can cast a shadow on the
stationary beacons
-
Keep the radio signal’s strength under control
-
The RSSI (Dashboard => right menu) of any beacon/modem must not be higher than -
25dBm. Otherwise, the system may malfunction
-
It is recommended the distance between the modem and beacons be no less than 0.5
–
1m. Beacons can be placed as close to each other as needed. If a beacon is extremely
close to the modem, disconnect the antenna from the beacon. Monitor the Received
Signal Strength Indicator (RSSI). It must be in the range of -25 to -70dBm. An RSSI of
less than -70dBm will work too, but packet losses may start occurring. The quality of the
radio connection very much depends on external interference as well because the used
band is ISM (either 915MHz or 433MHz) and there are numerous co-existing systems.
-
Use 30 - 50 periods (pulses) in settings instead of the default 5. Select:
-
Ultrasound settings => Number of periods
-
When you have large errors in position estimation (more than a 1m inaccuracy), use the
embedded Oscilloscope on
Dashboard => View
to determine which stationary beacon is
jammed
-
Reduce the gain of the ultrasonic manually depending on your system
