Filtering — An action performed by an Ethernet device, such as
a bridge, switch, or router, which excludes an Ethernet packet
from being passed from one subnetwork to another based upon
the packet's destination, source, or packet type.

Frequency Hopping — A spread spectrum technique by which
the band is divided into a number of channels and the transmis-
sions hop from channel to channel in a pre-specified sequence.

Interference — A situation that occurs when an unwanted RF
signal occupies the same frequency band as a desired signal.

IP Address — (Internet protocol address) — A 32-bit address
assigned to TCP/IP hosts.

Narrow Band — A channel of about 25 KHz bandwidth in the
RF spectrum. The FCC allocates Narrow Band channels and
issues a license to the user. Each user of a specific narrow band
frequency range must obtain a site license from the FCC.

Spread Spectrum — A radio data transmission modulation
technique by which the transmitted signal is spread over a band-
width wider than the information bandwidth. Spread Spectrum
bands are designated by the FCC and require no user license.
