How to Calculate Omnidirectional SIR?
Omnidirectional SIR calculator uses Omnidirectional SIR = 1/(2*(Frequency Reuse Ratio-1)^(-Propagation Path Loss Exponent)+2*(Frequency Reuse Ratio)^(-Propagation Path Loss Exponent)+2*(Frequency Reuse Ratio+1)^(-Propagation Path Loss Exponent)) to calculate the Omnidirectional SIR, Omnidirectional SIR represents the ratio of the signal strength from a mobile device to the interference it experiences from co-channel cells, assuming omnidirectional antennas. Omnidirectional antennas transmit and receive signals equally in all directions. Omnidirectional SIR is denoted by SIRomn symbol.
How to calculate Omnidirectional SIR using this online calculator? To use this online calculator for Omnidirectional SIR, enter Frequency Reuse Ratio (q) & Propagation Path Loss Exponent (γ) and hit the calculate button. Here is how the Omnidirectional SIR calculation can be explained with given input values -> 0.239387 = 1/(2*(1.78-1)^(-2)+2*(1.78)^(-2)+2*(1.78+1)^(-2)).
