Verified Actual Questions & Answers for Guaranteed
Pass / Newest Update
2.4 GHz wavelength - ✔✔ANSW✔✔longer wavelengths, better range
larger channel widths - ✔✔ANSW✔✔provide faster speed and throughput but can
create greater interference
Beamforming - ✔✔ANSW✔✔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 - ✔✔ANSW✔✔The increase in signal strength by the concentration of
radio waves by means of directional propagation.
ad hoc network - ✔✔ANSW✔✔wireless network where stations can communicate
directly to each other
infrastructure network - ✔✔ANSW✔✔wireless clients must connect through a central
wireless point that controls access to the wireless and wired networks
wireless network service sets - ✔✔ANSW✔✔BSS, BSSID, SSID, ESS
mesh network - ✔✔ANSW✔✔one or more AP's connected to the wired network
best practices for channel planning - ✔✔ANSW✔✔- 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 - ✔✔ANSW✔✔14, (1, 6, and 11 do not overlap and
these are the most used channels by AP)
How many channels in 5 GHz - ✔✔ANSW✔✔25 that do not overlap
Which channels are mainly used in 5 GHz - ✔✔ANSW✔✔20 and 40 MHz
For high density deployments - ✔✔ANSW✔✔use 20 MHz channel width in 2.4 GHz to
reuse channels
