UPDATED QUESTIONS AND CORRECT
ANSWERS
2.4 GHz wavelength - CORRECT ANSWERS✅✅longer wavelengths, better range
larger channel widths - CORRECT ANSWERS✅✅provide faster speed and throughput but
can create greater interference
5 GHz wavelength - CORRECT ANSWERS✅✅supports faster data rates at shorter
distances, suited for high density deployments because of greater number of channels that do
not overlap
What channel widths do 2.4 GHz support? - CORRECT ANSWERS✅✅20 and 40 MHz
What channel widths do 5 GHz support? - CORRECT ANSWERS✅✅20, 40, 80, 160 MHz
omnidirectional antenna - CORRECT ANSWERS✅✅Can transmit and receive with 360-
degree coverage
directional antenna - CORRECT ANSWERS✅✅directs signals where the antenna oints
Beamforming - CORRECT ANSWERS✅✅technology that enables wireless devices with
omnidirectional antennas to detect location of other wireless devices and direct a stronger
signal in the direction of the devices
Antenna Gain - CORRECT ANSWERS✅✅The increase in signal strength by the
concentration of radio waves by means of directional propagation.
ad hoc network - CORRECT ANSWERS✅✅wireless network where stations can
communicate directly to each other
