Telecommunications & RF Calculators
Convert dB amplification gains, solve frequency wavelengths for antennas, compute line transmission attenuation losses, calculate light propagation speed delays in optical fiber, evaluate Shannon capacity boundaries, and gauge Bit Error Rates (BER).
Fiber Latency & Speed
Calculate one-way and round-trip propagation delay (latency) over distance in copper, fiber optic glass, or vacuum (satellite).

Real-time CalculationsTelecommunication Constants
Decibels (dB) are logarithmic units expressing power ratios. A 3 dB change doubles or halves the power. A 10 dB change corresponds to a factor of 10.
Shannon-Hartley Theorem establishes the absolute maximum error-free data rate (capacity) for a noisy communication channel.
Velocity Factor (VF) is the speed of electromagnetic waves in a transmission line relative to their speed in vacuum. For example, light travels ~31% slower inside fiber glass than in empty space.
