Secure Wifi - Watchguard Test Correct
100%
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
wireless network service sets - ANSWER BSS, BSSID, SSID, ESS
mesh network - ANSWER one or more AP's connected to the wired network
For high density deployments - ANSWER use 20 MHz channel width in 2.4 GHz to
reuse channels
Co-channel interference (CCI) - ANSWER occurs when wireless radios transmit on the
same frequence in the same location
