FHSS (Frequency-Hopping Spread Spectrum) - Is transmis-
sion technology used in wireless transmissions where the data
signal is modulated with a narrowband carrier signal that
"hops" in a random but predictable sequence from frequency
to frequency as a function of time over a wide band of fre-
quencies. The signal energy is spread in time domain rather
than chopping each bit into small pieces in the frequency
domain. This technique reduces interference because a signal
from a narrowband system will only affect the spread spec-
trum signal if both are transmitting at the same frequency at
the same time. If synchronized properly, a single logical chan-
nel is maintained.

Firmware - Code that is written onto read-only memory (ROM)
or programmable read-only memory (PROM). Once firmware
has been written onto the ROM or PROM, it is still new settings
remain even when the device is turned off.

IEEE - The Institute of Electrical and Electronics Engineers, pro-
nounced I-triple-E, is an organization that develops standards
that often become national and international standards.

IP Address - An identifier for a computer or device on a TCP/IP
network. Networks using the TCP/IP protocol route messages
based on the IP address of the destination. The format of an IP
address is a 32-bit numeric address written as four numbers
separated by periods. Each number can be zero to 255. For
example, 192.168.2.25 is a valid an IP address.

IPCONFIG - A utility that provides for querying, defining and
managing IP addresses within a network. This utility is usually
run from the DOS prompt and is the perfect tool for trou-
bleshooting connection issues.

LAN - A local area network (LAN) is a group of computers and
associated devices that share a common communications line
and typically share the resources of a single processor or server
