What frequency does 802.11a support? - CORRECT ANSWER - OFDM
5ghz 54 mbps
What frequency does 802.11b support? - CORRECT ANSWER - DSSS
2.4ghz max rate at 11 mbps
what frequency does 802.11g support? - CORRECT ANSWER - ERP
2.4ghz at 54 mbps
what frequency does 802.11n support? (Wi-Fi 4 - HT ) - CORRECT ANSWER - HT
2.4ghz and 5ghz max rate of 600 mbps
what frequency does 802.11ac support? (Wi-Fi 5 - VHT) - CORRECT ANSWER - VHT
5ghz at max rate of 800mbs
what frequency does 802.11ax support (Wi-Fi 6 - HE) - CORRECT ANSWER - HE
, 2.4 and 5 Ghz
8 data strams
9.6 Gbps
what frequency does 802.11af support? - CORRECT ANSWER - this supports frequencies
under 1ghz
what frequency does 802.11ah support? - CORRECT ANSWER - 700mhz, 860mhz,
902mhz,
What is amplitude? - CORRECT ANSWER - Height of an RF wave
What is frequency? - CORRECT ANSWER - number of waves/cycles per second
what happens if you have a higher frequency in short distances? - CORRECT ANSWER -
The faster repetitions of frequency in low distances results in higher bandwidth.
what happens if you have a higher frequency in long distances? - CORRECT ANSWER -
The higher cycle rate causes the system to fade out quicker resulting in decreased bandwidth
What frequency is better at a longer distance? - CORRECT ANSWER - 2.4 ghz, because
the waves are longer and don't fade out as soon in comparison to 5ghz. so 2.4ghz is better at
longer distances.
What is gain? - CORRECT ANSWER - This is the increase of RF signal strength or
amplitude
What is loss? - CORRECT ANSWER - This is the decrease of RF signal strength or
amplitude
