NRTP
Non real time polling is similar to real time polling but is used to
request uplink bandwidth less regularly
O&M
Operations and maintenance
ODU
Outdoor unit associated with a ST
OFDM
Orthogonal frequency division multiplexing
PHY
The physical layer associated with the WiMAX interconnection stack
PMP
Point to multipoint radio systems architecture
PoE
Point to point protocol over Ethernet
PtP
Point to point radio systems architecture
QoS
Quality of service, which is used to specify level of data throughput
REC
Radio equipment controller
RTP
Real time polling allows a service flow to request uplink bandwidth at
regular intervals
Rx
Receiver
SDMA
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
SDR
Software defined radio
SF
Service flow
SFTP
Shielded Foiled Twisted Pair (cable type)
SME
Small to medium sized enterprise
SNMP
Simple network management protocol
SNR
Signal to noise
SOFDMA
Scalable orthogonal frequency division multiplexing
SoHo

transmission link
TDD
Time division duplex
TDM
Time division multiplexing
Tx
Transmitter
UCD
Uplink channel descriptor
UGS
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.
