APD Automatic Platform Detection. A mechanism that dtects the wreless
link protocol used by the Base Station, enabling automatic selection of
the Duplex Mode (FDD or TDD) to be used by the Subscriber Unit.
ATPC Automatic Transmit Power Control
AU Access Unit
BE Best effort. A service where neither throughput nor delay guarantees
are provided. The subscriber unit sends requests for bandwidth in
either random access slots or dedicated transmission opportunities.
The occurrence of dedicated opportunities is subject to network load,
and the subscriber unit cannot rely on their presence. Service
parameters include Committed Time (CT) and Maximum Information
Rate (MIR).
BPSK Binary Phase-Shift Keying. A data transfer technique. BPSK transmits
data using two phase modulation signals, one phase representing a
binary one, and the other representing a binary zero. The signal is
divided into bits; their status is determined by the preceding wave. If
the wave changes, for example, the signal is reversed.
BST Base Station
BWA Broadband Wireless Access
CF Compact Flash. A popular memory card that uses flash memory to
store data on a very small card.
CG Continuous Grant. Also known as Unsolicited Grant Services (UGS), is
tailored for carrying constant bit- rate (CBR) real-time services
characterized by fixed size data packets on a periodic basis such as
VoIP or E1/T1. Service parameters include unsolicited grant size
(packet size) and normal grant interval (sample interval).
CIR Committed Information Rate. The rate (in bits per second) at which a
network guarantees to transfer information under normal conditions,
averaged over a minimum increment of time.
