8.5 Glossary
Term
Acronym Definition
Active Service
Flow
-
An Admitted Service Flow that is active and available
for packet transmission.
Address
Resolution
Protocol
ARP
An IETF protocol for converting network addresses to
48-bit Ethernet addresses.
Admitted
Service Flow
-
Service Flow is registered, but not active.
RedMAX base
station System
The base station terminal, transceiver, and antenna.
RedMAX base
station terminal
The base station indoor unit.
Antenna Gain
-
The measure of antenna performance relative to a
theoretical antenna called an isotropic antenna.
Automatic
Repeat Request
ARQ
This protocol is used for selective retransmission of
lost fragments over the air.
Base Station
BS
The RedMAX base station Base Station terminal
configured as central equipment (also referred to as a
base station).
Beamwidth
-
The angle of signal coverage provided by an antenna.
Best Effort
Service
BE
BE service provides efficient service to best effort
traffic. In order for this service to work correctly, the
Request/Transmission Policy setting should be such
that the Subscriber is allowed to use contention
request opportunities. This results in the Subscriber
using contention request opportunities as well as
unicast request opportunities and unsolicited Data
Grant Burst Types. All other bits of the
Request/Transmission Policy are irrelevant to the
fundamental operation of this scheduling service and
should be set according to network policy. The key
service elements are the Minimum Reserved Traffic
Rate, the Maximum Sustained Traffic Rate, and the
Traffic Priority.
Binary Phase
Shift Keying
BPSK
BPSK is a digital modulation technique. This type of
modulation is less efficient than similar modulation
techniques such as QPSK and 64 QAM, but is less
susceptible to noise.
Bps
Bps
A unit of measurement for data is transfer.
Broadband
Fixed Wireless
BFW
High-speed wireless installation where the equipment
is not mobile.
Broadcast
Addresses
-
A predefined destination address that denotes the set
of all data network service access points.
Burst
-
A group of protocol data units (PDUs) transmitted over
the wireless link using the same profile.
