CalcRF

Features CalcRF

The CalcRF calculator allows:- to evaluate the exposures generated by relay antennas in a simple case,- to convert surface powers in mW/m² into electric fields in V/m (and vice versa),- to convert attenuations given in decibels into ratios (and vice versa),- to take into account the measurement uncertainties for the exposures obtained by EXEM in the context of case A,- to evaluate the probability that an Exem measurement lower than 6 V/m corresponds to an exposure higher than 6 V/m,- to check the consistency between the DIMs and the simulation reports (EIRP vs Electrical Powers),- to calculate an EIRP power from an electrical power and the antenna gain,- to calculate the quadratic sum of 2 electric fields,to obtain the EIRP power of the antenna equivalent to several mobile phone systems in simple cases,- to evaluate the electric field arriving on an antenna from the electrical power delivered by the antenna.Organization :The calculator includes 7 specialized modules.Navigation in a module:Each screen can be moved up and down using the scroll bar on the right.Navigation from one module to another:Use the control buttons located at the bottom of each module.Calculation of exposure levels:- The CalculetteCalcRF V2.1 only takes into account the waves which go directly from the antennas to the exposure calculation point, in accordance with the recommendations of the National Frequency Agency (no reflected or diffracted waves).- When the tilts of the radiative elements of the 2G/3G/4G/5GDSS antenna (false 5G) have fairly close values, it is possible to construct an equivalent macro-antenna whose EIRP is the sum of the EIRP of the radiative elements.
The WORST sum converted to decibels is then used for the simulation.
The EIRP of the 5G 3500 MHz antenna does not need to be calculated because it is provided in the Town Hall Information File (DIM).- The simulation module provides exposure levels depending on the distance to the antennas for a 2G/3G/4G/5GDSS antenna and a 5G 3500 MHz antenna.
The calculation point must be located on the axis of the fixed beam antenna and in direct view of it.
It is possible to insert (or not) glazing in the path of the direct wave.The site https://sites.google.com/view/cemethconseil:You will find on this site a lot of information on the exposures generated by the relay antennas and on the documents submitted by the Operators to the Town Halls for each antenna installation project.
The site also offers free access to an online course on Electromagnetic Fields and Radio Frequencies.
You will be able to download several easy-to-use tools allowing you to model exposures in the case where the calculation point is located outside the axis of the fixed beam antenna.Contact :A graduate engineer from the Grandes Écoles sciences, I advise the technical teams of town halls, associations and individuals on a voluntary basis.
