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 300-48TM- Extreme Networks 48 port 10/100 switch with four GBIC ports, PoE, and Altitude 300-2TMconfiguration software.
