GLOSSARY
AUTHENTICATION The process to verify the identity of a subscriber requesting network
access.
BANDWIDTH The difference between the highest and lowest frequencies available for
network signals. Also synonymous with network speed, the actual speed of
data transmission through a medium.
BASE STATION A WIMAX service provider’s equipment that is installed at a fixed location
to provide network connectivity for subscriber stations within a defined
service area.
CINR Carrier-to-Interference-Plus-Noise-Ration: A measurement of the channel
quality in a WiMAX link. Subscriber stations measure the received CINR
and send the information back to the base station. The base station can
then adjust modulation and coding for the link to optimize throughput.
CENTER FREQUENCY The radio frequency at the center of a WiMAX channel. WiMAX channels
can be of different widths (the channel bandwidth) and the transmitted
radio signal is spread across the full width of the channel.
CHANNEL BANDWIDTH The range of frequencies occupied by a WiMAX radio signal. The amount of
information that can be transmitted in a radio signal is related to the
channel bandwidth, which is measured in Megahertz (MHz). WiMAX
supports a range of channel bandwidths that can be defined by the service
operator depending on performance requirements, operating preferences,
and regulatory constraints.
CPE Customer-Premises Equipment: Terminal equipment provided by a service
provider that is located at a subscriber’s premises and supports a
communication channel between a customer and the service provider.
CPU Central Processing Unit: The CPU, or processor, is the part of a computer
where most calculations take place. In most of today’s PCs, the CPU is
contained on a single chip. The type and speed (in GHz) of a CPU largely
defines the processing power of a computer.
