Channel capacity is the tight upper bound on the (data) rate at which a transmitter can reliably send information over a communications channel. You can calculate it using the following equation:
C (MBPS) = B (MHz) x log2(1 + S/N), where you can interchange S/N and C/N, which is a power ratio (not in dB)
Here are the steps to create the formula, using the Calculation Tool:
1) Create a Data Element for C/N from the Link Information Data Provider for an access between a transmitter and a receiver.
2) Convert C/N from dB and add one to form the result: R = (1+C/N).
3) Use the binary logarithmic single variable function to form result: L = log2(R).
4) Create a Data Element for Bandwidth (B) from the Link Information Data Provider for an access between a transmitter and a receiver.
5) Use a multiplication two variable function to form the result: Capacity = B x L.
Use this Capacity Scalar Calculation to create a Figure of Merit for a Coverage between a transmitter Asset and receiver Grid Object or a receiver Asset and transmitter Grid Object.
