Glossary C-2 Glossary Terms
Average power : Average power is the peak power averaged over time
and is usually applied to pulsed systems where the
carrier power is switched on and off.
Backhaul : In wireless technology, backhaul refers to transporting
voice and data traffic from a cell site to the switch.
Band Pass Filter : A Band Pass Filter is a radio wave filter with a specific
range of frequencies in which it is designed to pass. It
rejects frequencies outside the pass-band range. A
resistor-inductor-capacitor circuit is an example of a
Band Pass Filter.
Bandwidth : Bandwidth usually identifies the capacity of a circuit or
amount of data that can be sent through a given circuit.
It may be user-specified in a PVC. It is an indication of
the amount of data that is passing over a medium. Also,
bandwidth is the portion of the frequency spectrum
required to transmit desired information. Each radio
channel has a center frequency and additional
frequencies above and below this carrier frequency
which is used to carry the transmitted information. The
range of frequencies from the lowest to the highest used
is called the bandwidth.
Bandwidth Ratio : Bandwidth Ratio is the ratio of two devices having
differing bandwidths, not necessarily in the same
frequency spectrum.
