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 jump s from one narrow frequency band to another
many times per seconds.
ESSID
An Infrastructure configuration could also support roaming capability f or 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 w hile 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.
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

Infrastructure
An integrated wireless and wired LAN is called an Infrastructure configuration. Infrastructure is
applicable to enterprise scale for wireless access to central database, or wir eless application
for mobile workers.
Network
A network is a system of com puters that is c onnected. Data, files, and messages can be
transmitted over this network. Networks may be local or wide area networks.
ISM Band
The FCC and their counterparts outside of the U.S. have set aside bandwidth for unlicensed
