WATCHGUARD SECURE WIFI – EXAM
2025
2.4 GHz wavelength - Answer longer wavelengths, better range
larger channel widths - Answer provide faster speed and throughput but can create greater interference
5 GHz wavelength - Answer 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? - Answer 20 and 40 MHz
What channel widths do 5 GHz support? - Answer 20, 40, 80, 160 MHz
omnidirectional antenna - Answer Can transmit and receive with 360-degree coverage
directional antenna - Answer directs signals where the antenna oints
Beamforming - Answer 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 - Answer The increase in signal strength by the concentration of radio waves by means of
directional propagation.
ad hoc network - Answer wireless network where stations can communicate directly to each other
infrastructure network - Answer wireless clients must connect through a central wireless point that
controls access to the wireless and wired networks
