Document Content and Description Below
Q. what word describes the bending of an RF signal as it passes through a medium of a varying density from that of free space - ✔✔Refraction Q. What can cause an excessively high VSWR (voltage s... tanding wave ratio)in a WLAN RF transmission line? - ✔✔An impedance mismatch in the RF cables and connectors Q. What factors influence the distance that an RF signal can be effectively received? - ✔✔*Receiving station's radio sensitivity *Free Space Path Loss *Transmitting station's output power Q. As an RF wave propagates through space, the wave front experiences natural expansion that reduces its signal strength in an area. what term describes the rate at which this expansion happens? - ✔✔Inverse square law Q. Return Loss is the decrease of forward energy in a system when some of the power is being reflected back toward the transmitter. - ✔✔Am impedance mismatch between components in the RF system Q. What factors are taken into account when calculating the link budget of a point-topoint outdoor WLAN bridge link? [Show More]
