What are regulatory bodies?
What is Canada's Regulatory Body?
How many Channels according to the FCC in 2.4ghz band?
In 5 GHZ its dependent on the sub band. How many sub bands are under 5 Ghz?
all sub bands are approved for indoor but which is restricted from out door use?
How wide are WLAN channels?
Which Channels are non overlapping?
What standards govern the 2.4 GHZ band
How many channels in 5GhzÉ
How many channels in the 5 Ghz spectrum?
What Standards govern the 5Ghz band?
Which band has less interference
What is Modulation?
Differential Binary Phase Shift Keying (DBPSK) does what to the wave when it hits a 1?
Differential Quadrature Phase Shift Keying (DQPSK) does what differently?
Complementary Code Keying (CCK) uses 6 bit symbols to achieve what speed? under what IEEE standard?
to avoid over lap we use orthogonal (at 90 degree angle of one another)
or ?
OFDM is used in what IEEE standards?
BPSK and QSK adjusted where the wave started from what does QAM also adjust for faster transmission?
To improve reliability and resistance QAM repeats the packets. (match not question)
That was 16-QAM next is 64-QAM
(not a question)
What is dynamic rate shifting (DRS).
802.11b Characteristics?
802.11g Characteristics?
802.11a Characteristics?
802.11n Characteristics?
What is MIMO?
What technologies support MIMO
