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 frequencies. 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 spectrum signal if both are
transmitting at the same frequency at the same time. If
synchronized properly, a single logical channel 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.

Fragmentation Threshold- This specifies the maximum size a
data packet will be before splitting and creating a new packet
and should remain at its default setting of 2,346. A smaller
setting means smaller packets, which will create more packets
for each transmission. Only minor modifications of this value are
recommended.

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 sep-
arated 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.
