An Ad-Hoc wireless LAN is a group of computers each with
LAN adapters, connected as an independent wireless LAN.
Ad-Hoc Mode
The core infrastructure of a network. The portion of the
network that transports information from one central
location to another central location where it is unloaded
onto a local system.
In mobile telecommunications, a base station is the central
radio transmitter/receiver that maintains communications
with the mobile radiotelephone sets within its range. In
cellular and personal communications applications, each cell
or micro-cell has its own base station; each base station in
turn is interconnected with other cells or bases.
BSS stands for Basic Service Set. A Basic Service Set is
comprised of a WAP and all the LAN PCs that are associated
with it.
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 BSSes in an
ESS (ESS-ID, SSID).
A popular local area data communications network, which
accepts transmission from computers and terminals. Ethernet
operates on a 10 or 100Mbps base band transmission rate,
using an unshielded, twisted-pair cable.
