• 802.11a

• 802.11b

• 802.11g

• 802.11n

What does DSSS do to the RF (Radio Frequency)

• makes the frequency higher

• spreads the signal over a wider frequency

• terminates the frequncy

• Boosts the Frequency

As it relates to DSSS - A properly configured receiver can...

• reverse the the DSSS and re-construct the original signal

• Read the new Radio Frequency

• nothing, the signal is lost
