Telecom Link Master

Telecom Link Master is a local utility app designed for telecommunications field technicians and RF engineers. It provides a suite of offline calculators and tools to assist with site installation, alignment, and signal path calculations

Key Features:

* Antenna Downtilt Calculator:
- Input transmitter tower height, receiver/target height, and ground link distance.
- Calculate the mechanical downtilt angle.
- Optionally input antenna vertical beamwidth to estimate the 3dB half-power beamwidth coverage boundaries (inner and outer edges).

* Free Space Path Loss (FSPL) Estimator:
- Input transmission frequency and path distance.
- Support for frequency units (MHz/GHz) and distance units (km/miles).
- View a sweep of attenuation values ​​across different distance reference points.

* Power Decibel Converter:
- Convert power levels instantly between dBm, dBW, and Watts.
- Refer to common equipment benchmarks (such as macro base station RF, standard Wi-Fi router, or receiver thresholds).

* Fresnel Zone Calculator:
- Compute the first Fresnel zone radius at path midpoint.
- Calculate the absolute 60% clearance boundary to evaluate path obstruction risks.
- Optionally compute Fresnel radius at specific obstacle distances along the path.

* VSWR & Return Loss Analyzer:
- Input Voltage Standing Wave Ratio (VSWR) to assess connector matching.
- Calculate Return Loss in dB, Reflection Coefficient (Gamma), Mismatch Loss in dB, and Reflected Power percentage.
- View a quick conversion reference matrix for common VSWR values.

Cell Site Installation Checklist:
- Track site validation progress using a built-in compliance checklist.
- Tasks are categorized by Antenna, Cabling, Grounding, Alignment, Testing, and Closeout.
- Add custom tasks with tailored titles, categories, and descriptions.
- Filter tasks by status (All, Pending, Completed) and reset the checklist as needed.

Offline & Settings Configuration:
- Configure preferences for measurement units and dark/light system themes.
- View the built-in offline Privacy Policy. All inputs and calculations are processed locally on your device.
