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.
