Secure WIFI - Watchguard Test
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? - answer20 and 40 MHz
What channel widths do 5 GHz support? - answer20, 40, 80, 160 MHz
omnidirectional antenna - answer Can transmit and receive with 360-degree coverage
directional antenna - answer directs signals where the antenna points
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 - answerThe increase in signal strength by the concentration of radio
waves by means of directional propagation.
ad hoc network - answerwireless network where stations can communicate directly to
each other
infrastructure network - answerwireless clients must connect through a central wireless
point that controls access to the wireless and wired networks
wireless network service sets - answerBSS, BSSID, SSID, ESS
mesh network - answerone or more AP's connected to the wired network
best practices for channel planning - answer- To avoid co-channel interference, make
sure that adjacent APs do not overlap channels.
- Larger channel widths can provide better throughput, but they can cause more
interference
in high density areas.
How many channels in 2.4 GHz - answer14, (1, 6, and 11 do not overlap and these are
the most used channels by AP)
