A collection of easy to use calculators for fast estimation of common radio calculations. Each calculator includes a description of the formula used which also makes this a handy educational tool.
Bonus: Funny 'Quotations' with a technical flavor that will make you smile.
Many of the calculators below also support reverse calculations ie find inputs needed to provide a desired result.
Radio Calculations in RFCalc2 include:
Antenna Gain: _______ Typical Antenna Gain from size and frequency.
Antenna Tilt: ________ 3dB service radius for a radio site from the antenna gain and tilt.
Cable Loss: __________Feeder losses of a given cable type, frequency and cable length.
CDF: ________________Cumulative Distribution Function for Normal Distribution
Channel Rate: _______ Max radio channel Data Rate.
Coverage Margin: _____ Increase in signal level at cell edge required to meet an area coverage probability.
Erl Traffic: ___________ Erlang B formula to calculate erlangs or blocking or number of channels.
Fresnel: ____________ 60% Fresnel path clearance.
Horizon: _____________ Distance in Km to the radio Horizon.
Noise Rise: _________ Increase in Receiver Noise Floor caused by an interfering signal.
Packet Loss: ________ Max TCP data rate for given packet loss and Round Trip Time.
Path Loss: __________ Free Space or Hata propagation loss for a given frequency.
Power: ______________ Convert Watts to dBm or dBm to Watts.
Propagation Delay: ____ Signal delay travelling a distance through different medium eg Air.
Receiver Sensitivity: __ Calculate radio Receiver Sensitivity.
TCP Window: ________ Calculate max TCP rate for given buffer size.
VSWR: ____________ Calculate Return Loss in dB for a given VSWR.
Wavelength: _________ Convert between Frequency and Wavelength.
This is a handy pocket RF calculator that gives quick and easy results, for example when doing field work. RF Calc 2 has 18 calculators with 47 different calculations to provide one tool that can quickly solve a broad range of RF problems.
