gathered. The scanned channels will be all the frequencies included in the 
selected sub-band. 
Upon activating the spectrum analysis the unit will automatically reset. During 
the information-gathering period the unit will not receive nor transmit data. It 
also will not be able to synchronize/associate, meaning that it cannot be 
managed via the wireless link. During the spectrum analysis period the unit 
security mode is changed to promiscuous to enable gathering information 
regarding all legal frames received by the unit. At the end of the period the unit 
will reset automatically regaining normal operability upon start up.
