What does a radio require?
Ans: A transmitter, A receiver, the over-the-air medium between the
transmitter and receiver
2.4Ghz has a longer wavelength than 5Ghz but is more susceptible to
interference. This means...
Ans: 2.4Ghz has longer range and can penetrate floors and walls.
Dynamic Frequency Selection (DFS) allows wireless devices to
Ans: share parts of the 5 and 6 Ghz frequency. A 5 and 6 Ghz device will use
DFS to switch channels if radar is detected.
2.4Ghz Bands
Ans: 802.11, 802.11b, 802.11g, 802.11n, 802.11ax
5 Ghz Bands
Ans: 802.11a, 802.11n, 802.11ac, 802.11ax
6 Ghz Bands
Ans: Wi-Fi 6E
Beamforming is used with omnidirectional antennas
Ans: to increase their strength in the direction of the connected client
devices
Spatial stream

Ans: is a wireless data signal transmitted or received by an antenna. The
more antennas an access point has the more data it can receive/transmit at
one time
If the noise level is too high
Ans: it can degrade the strength and performance of your wireless signals.
Power loss can significantly affect
Ans: the range and throughput of your wireless devices.
Signal strength
Ans: is the wireless signal power level received by a wireless client. A strong
signal strength results in more reliable connections and higher speeds but can
also cause interference with nearby devices.
A decibel (dB)
Ans: is a relative measure of RF power.
A watt
Ans: is an absolute measure of RF power
The signal strength is represented in dBm format (0 to -100)
Ans: This is the power ratio in decibels (dB) of the measured power
referenced to one milliwatt (mW).
The closer the value is to 0
Ans: the stronger the signal. For example, -45 dBm is better signal strength
than -65 dBm
The noise level is measured in dBm format (0 to -100 dBm)
Ans: This is the power ratio in decibels (dB) of the measured power
referenced to one milliwatt.
