Out door unit associated with a ST
Orthogonal frequency division multiplexing
The physical layer associated with the WiMAX interconnection stack
Point to multipoint radio systems architecture
Point to point protocol over Ethernet
Quality of service, which is used to specify level of data throughput
Radio equipment controller
Real time polling allows a service flow to request uplink bandwidth at regular intervals
Receiver
Space division multiple access is a technique which makes it possible to increase the capacity of a cellular mobile radio system by taking advantage of spatial separation between users
Software defined radio
Service flow. Definition: Unidirectional flow of MAC SDUs
SF Identifier. Definition: Unique 32 bit unsigned integer
Small to medium sized enterprise
Simple network management protocol
Signal to noise
Scaleable orthogonal frequency division multiplexing

Subscriber Station (interchangeable with CPE or ST). Definition: Generic name of subscriber logical entity as defined in the 802.16-2004 standard
Subscriber terminal (interchangeable with CPE or SS). Definition: Alternative generic name of subscriber logical entity.
Space time coding
North American standard 1.56Mb/s pulse code modulated transmission link
Time division duplex
Time division multiplexing
Transmitter
Uplink channel descriptor
Unsolicited grant service used to provide fixed bandwidth slots on the uplink for an ST to transmit data at regular intervals. The bandwidth should be used by the UGS SF, however the final decision of which SF (if any) uses the bandwidth slot is made by the ST.
Voice over Internet protocol
WiMAX is a wireless industry coalition whose members are organized to advance IEEE 802.16 standards for broadband wireless access (BWA) networks.
