Bluetooth Range Calculations
Our assumptions for the two examples are:
Abbreviation |
Description |
meters |
feet |
---|---|---|---|
OL |
Overall Length of tow vehicle (bumper to bumper) |
6 |
20 |
RVL |
Overall Length of RV (tongue to bumper) |
7 |
24 |
T2FS |
Tongue to front storage (pass through) |
1.5 |
5 |
FB2FS |
Front Bumper to Front Seat of tow vehicle |
2 |
6 |
BLE |
Operating Range of Bluetooth LE Radio (Class 1.5) |
30 |
100 |
Attention
To improve the reliability of the connection we take the theoretical range (from the Chart) for a class 1.5 device and divide it by a factor of four. This will effectively take our range from the theoretical maximum of 30 m (100ft) to 7.5m (25ft).
Tow Vehicle
![_images/truck.gmc.1500.measurements.png](_images/truck.gmc.1500.measurements.png)
Tow Vehicle - GMC 1500 Pickup Truck
Travel Trailer

Travel Trailer - Lance 1995
Example 1 - Worst Case - Level Up module at Rear of RV
In this example we will mount the Level Up Pro module at the rear of the trailer - absolute worst case
Metric
-3.5 m = (30 m / 4) - ((6 m - 2 m) + 7 m)
Imperial
-13.0 ft = (100 ft / 4) - ((20 ft - 6 ft) + 24 ft)
Example 2 - Best Case - Level Up module in Front Pass Through
In this example we will mount the Level Up Pro module in the front pass through storage of the RV
Metric
+2.0 m = (30 m / 4) - ((6 m - 2 m) + 1.5 m)
Imperial
+6.0 ft = (100 ft / 4) - ((20 ft - 6 ft) + 5 ft)
Bottom Line
If the result of the calculation is a negative number, you may experience Bluetooth Low Energy (BLE) connection issues between your mobile device and the Level Up module.
