other method is frequency hopping. Direct sequence spreads the data over one frequency

range (channel) while frequency hopping jumps from one narrow frequency band to another

many times per seconds.

ESSID

An Infrastructure configuration could also support roaming capability for mobile workers. More

than one BSS can be configured as an Extended Service Set (ESS). Users within an ESS

could roam freely between BSS s while served as continuous connection to the network

wireless stations and Access Points within an ESS must be configured with the same ESSID

and the same radio channel.
