RF Link Calc 2.0

RFLinkCalc serves as an indispensable numerical calculation tool tailored for radio engineers, focusing primarily on the intricacies of RF link characterization, including Wireless Internet (WiFi) applications. This versatile utility allows users to compute essential parameters such as maximum distance, required transmitter power levels, and gain margins with relative ease.

The interface invites users to input a comprehensive set of values, while the software autonomously derives the necessary calculations. The required inputs include:

• Frequency in MHz
• Transmitter Power in dBm
• Transmitter Antenna Gain in dBi
• Transmitter Cable Loss in dB
• Distance in miles or kilometers
• Receiver Sensitivity in dBm
• Receiver Antenna Gain in dBi
• Receiver Cable Loss in dB
• Gain Margin in dB

In addition to these computations, RFLinkCalc also provides valuable metrics such as Free Space Loss and Received Signal levels.

The EIRP/ERP Calculator is another notable feature that accurately computes Effective Isotropic Radiated Power (EIRP) and Effective Radiated Power (ERP) both in watts and dBm, drawing upon user-provided transmitter power and antenna gain. Furthermore, it calculates field strength values in dBuV/m for distances of 3 and 10 meters, offering a clear perspective on signal propagation.

The Field Strength Calculator enhances usability by facilitating conversions between various measurement units, including:

• V/m (volts per meter)
• dBuV/m (dB relative to one microvolt per meter)
• dBuA/m (dB relative to one microampere per meter)
• pT (pico Tesla)
• dBpT (dB relative to one pico Tesla)
• Tesla
• Gauss
• A/m (amperes per meter)
• mW/cm² (milliwatts per square centimeter)
• W/m² (watts per square meter)
