Fix Poor Cell Signal Indoors: Use the Bolton Signal Booster Calculator
For South African residents and businesses experiencing poor cellular signal, Bolton Technical's Cell Phone Signal Booster System Calculator provides a data-driven approach to identifying optimal signal enhancement solutions.
This technical guide demonstrates how to effectively utilize the calculator to select the appropriate signal boosting system for various environments and applications.

Understanding the Signal Booster System Calculator
The Signal Booster System Calculator is a proprietary analytical tool available on the Bolton Technical South Africa website that evaluates:
- ✓ Building dimensions and coverage requirements
- ✓ Existing outdoor signal strength measurements
- ✓ Specific usage scenarios and network requirements
Residential Solutions
For homes and small apartments
Commercial Solutions
For offices and small businesses
Enterprise Solutions
For large facilities and industrial sites
Step-by-Step Guide to Using the Calculator
1. Measure Outdoor Signal Strength
Utilize your smartphone's Field Test Mode to obtain signal strength measurements in dBm:
Signal Range | dBm Value | Quality |
---|---|---|
Excellent | -50 to -70 dBm | Strong signal |
Moderate | -71 to -85 dBm | Average signal |
Poor | -86 to -100+ dBm | Weak signal |
2. Select Application Environment
Identify your primary use case:
- • Residential properties (homes, apartments, cottages)
- • Commercial spaces (offices, retail stores, clinics)
- • Large facilities (warehouses, factories, campuses)
3. Input Coverage Area Requirements
Specify the square meterage requiring signal enhancement:
- • 200 m² for standard residential applications
- • 500-1,000 m² for commercial spaces
- • 5,000-8,000 m² for industrial applications
4. Review Recommended System
The calculator will generate a technical recommendation such as:
- • WilsonPro A500 for residential use
- • WilsonPro A1000 for commercial applications
- • Enterprise-grade DAS solutions for large facilities

Not Sure What Your Signal Strength Means?
If your phone shows -110 dBm or worse, your outdoor signal may be too weak for even the best booster. Consider these steps:
-
Use our Signal Report Tool
-
Move to a window or rooftop to test stronger areas or use Cellmapper to find your nearest Tower
