Bandwidth
The size of a communications channel, measured in cycles per
second. "Bandwidth" is often used as a synonym for data rate.
Base Station
The central control unit of the wireless network. A base station
polls remote units and routes traffic to them. The base usually
connects to a major access point of main network.
Beamwidth
The beamwidth of an antenna describes how a signal spreads out
from the antenna, as well as the range of the reception area.
Beamwidth is measured between the points on the beam pattern
at which the power density is half of the maximum power. These
are often called the -3 dB points. A high-gain antenna has a
narrow beamwidth and may be more difficult to align.
BER
Bit Error Rate.
The proportion of bits received with errors. The default
measurement is per million sent.

Cable Loss
The loss a signal experiences as it passes through a cable.
Expressed in dB.
CAM

Channel
The width of the spectrum band taken by a radio signal, usually
measured in kilohertz (kHz).
Chip Rate
Chip rate signifies the time occupied by a single frequency. Also
the period of a code clock, or the output of a code generator
during one clock interval.
CPE
Customer Premise Equipment – the remote or subscriber unit in
the EION Broadband Wireless Access System.
Co-Location
Placing antennas in the same place. With proper frequency
planning, one rooftop may host up to six antennas, each attached
to a different AP ODU and Power inserter.
Coaxial Cable
A type of wire that has an inner conductor surrounded by an outer
conductor. The outer conductor also serves as an electrical shield.
Collision
A collision occurs when two devices send signals over the same
medium at the same frequency at the same time.
Community
Names
A kind of password. The Public Community Name offers read-only
SNMP access to the AP and CPE. The Private Community name
grants write access.
Configuration
Menus
The menus in the user interface on the Access Points that allows
the operator to view and configure their parameters.
