Cisco ANT-4G-DP-IN-TNC= Multiband Swivel Mount Dipo FD

let's continue our antenna theory basics to talk about a few important parameters such as the eirp fspl and rssi to better understand the upcoming proof of coverage version 11. [Music] before we start let's take a look at the current version 10 poc curve essentially the validity of a beacon beam witnessed is determined by the red curve shown on this graph for the u.s it's looking at the signal to noise ratio on the horizontal axis relative to the strength of the received signal coming in shown on the vertical axis as the rssi anything above the red curve bueno anything below the red curve no good as an example here we have a valid beacon being witnessed by this random hotspot with snr of 10 and rssi of -101 another example snr minus 3.8 rssi minus 100 dbm both are still in the green zone in some cases when a signal is too weak or too strong it gets deemed as invalid such as this one her
