◉ What challenges do WISPs have to overcome in order to
provide "last mile data delivery"
to customers?
Answer: Distance to APs, rooftop access, lightning, trees, mountains,
tower access, and other physical obstacles to connectivity.
◉ A transmitter outputs 100 mW. An antenna cable connects the
transmitter to an amplifier, and the power into the amplifier's
input measures 50 ml. The amplifier increases the signal to
the original transmitter's power level and sends the signal to
the antenna. The antenna receives the signal from the
amplifier at 75 mW, and then transmits at 150 mW. What is the
IR's power level in this F circuit?
Answer: 75mW
◉ Given an AP with 100 mW of output power connected through
a cable with 3 dB of loss to the antenna with a 10 dBi gain,
what is the approximate EIRP level from the antenna in mW?
,Answer: 500 mW
◉ What unit of measurement is used to express the gain of an
antenna?
Answer: dBi.
◉ What is EIRP?
Answer: The power actually radiated by the antenna element.
◉ Why is the Fresnel zone important to the integrity of the RF
link or path?
Answer: The Fresnel Zone defines an area around the RF line-of-
sight (RF LOS) that can introduce RF signal interference if blocked.
◉ How does RF LOS differ from visual LOS?
Answer: RF LOS is accompanied by a Fresnel zone, a series of
concentric
ellipsoid-shaped areas around the visual LOS path.
◉ What are some measures that can be taken to prevent high
VSWR in transmitters and receivers?
, Answer: Tighten connections between cables and connectors and
use
impedance-matched hardware throughout.
◉ Which of the provided VSWR shown here is best for
transferring radio frequency (RF) energy between
connections?
Answer: 1.2:1
◉ Which one of the following RF behaviors is defined as "the
bending of a wave as it passes through a medium of different
density?
Answer: refraction
◉ In what manner do radio waves propagate (move) away from
the source (antenna)?
Answer: In a straight line in all directions at once.
◉ What is the width of direct sequence spread spectrum (DSSS)
channels and how far apart are their center frequencies spaced?
Answer: 22 megahertz (MHz) and 5 MHz.apart
