Direct Sequence Spread Spectrum
This is the method the wireless cards use to transmit data over the frequency spectrum. The 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 second.
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 BSSs while
served as a 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.
Ethernet
Ethernet is a 10/100Mbps network that runs over dedicated home/office wiring. Users must be wired to the
network at all times to gain access.
Gateway
