Theoretical channel capacity
344 Mbps
Approx. non-overlapping channels available
12
Channel width
40 MHz
Usable spectrum modeled
500 MHz
5/6 GHz offers far more non-overlapping channels and wider channel widths, improving throughput and reducing interference.
Formula and working
Non-overlapping channel spacing ≈ channel width (MHz); Capacity (Mbps) ≈ channel width × spectral efficiency (bits/Hz)
- 1
Collect the inputs
Band = 1; Channel width (MHz) = 40; Spectral efficiency (bits/Hz, e.g. MCS) = 8.6
- 2
Apply the formula
Non-overlapping channel spacing ≈ channel width (MHz); Capacity (Mbps) ≈ channel width × spectral efficiency (bits/Hz)
- 3
Result
Theoretical channel capacity = 344 Mbps
