Extended Service Set Identifier, defines the coverage area.
Prior to the release of the 802.11 specification the ESS_ID
was called the Net_ID or Network Identifier. For terminals
using Spectrum24 radios with the 802.11 protocol, an
ESS_ID allows facilities to limit which Access Points a
mobile computer can communicate with. It is set on the
Network tab of the Control Panel. The terminal can only
communicate with Spectrum24 Access Points that have
matching ESS_IDs.
Ethernet communication port. Allows a wired interface to a
radio network.
An additional megabyte of non-volatile memory for storing
application and configuration files.
Flash memory is nonvolatile, semi-permanent storage that
can be electronically erased in the circuit and
reprogrammed. Series 9000 mobile computers use Flash
memory to store the operating system (ROM-DOS), the
terminal emulators, and the Citrix ICA Client for DOS.
A TCP/IP application protocol governing file transfer via
network or telephone lines. See TCP/IP.
The use of a random sequence of frequency channels to
achieve spread spectrum compliance. Stations that use
frequency hopping change their communications frequency
at regular intervals. A hopping sequence determines the
pattern at which frequencies are changed. Messages take
place within a hop. See Hopping Sequence and Spread
Spectrum.
See File Transfer Protocol.
Flash memory is responsible for storing the system
firmware and is non-volatile. If the system power is
interrupted the data is not lost.
