Estimated result of delay spread
-Result of simplified ray tracing
maximum delay : 3.3 us
rms delay spread : ~ 600 ns
-Estimated maximum delay
maximum delay : 6.4 us
rms delay spread : 1 us
-Result suggests S-V type cluster model, typical in indoor WLAN
also works in outdoor industrial use case, if the available channel
bandwidth is sufficiently wide, e.g. 1~5MHz.
