Terminology
on both the basic requirements of network management while adding valuable
and intuitive features that help save time by streamlining common tasks.
ESS - ESS (ESS-ID, SSID) stands for “Extended Service Set.” More than one BSS
is configured to become an Extended Service Set. LAN mobile users can roam
between different BSSs in an ESS (ESS-ID, SSID).
Ethernet - A popular local area data communications network, which accepts
transmission from computers and terminals.
Infrastructure - An integrated wireless and wired LAN is called an
infrastructure configuration.
ISM
- The Industrial Scientific and Medical band of regulated but unlicensed
frequencies. The size and position of the band varies among different regulatory
agencies. In the Americas the ISM S band is from 2.4 GHz to 2.4835 GHz and
the ISM C band is from 5.725 GHz to 5.875 GHz which is also part of the UNII
band.
Plenum (Hanging Ceiling) - The environmental air space above the ceiling tiles
of a hanging ceiling. Equipment in the plenum must be tested for fire resistance
and low-smoke-producing characteristics.
PoE
- Power Over Ethernet. This is an IEEE standard 802.3af that specifies how
power is delivered over Ethernet twisted pair cables.
RADIUS - Remote Authentication Dial-In User Service. A login and password
server standard originally developed for ISP telephone modem bank service
accesses. RADIUS is now widely used for any general login process.
Roaming - A wireless LAN mobile user moves around an ESS and maintains a
continuous connection to the infrastructure network.
RTS Threshold - Transmitters contending for the medium may not be aware of
each other. RTS/CTS mechanism can solve this “Hidden Node Problem.” If the
packet size is smaller than the preset RTS Threshold size, the RTS/CTS
mechanism will NOT be enabled.
Summit 300-48
TM
- Extreme Networks 48 port 10/100 switch with four GBIC
ports, PoE, and Altitude 300-2
TM
configuration software.
