Figure 6-7 WiMAX Advance Configure
Center Frequency
– Configures the centre frequency used by the WiMAX service.
Bandwidth
– Configures the channel bandwidth used by the WiMAX service.
Hand Over Enable
– Enable handoffs when moving between base stations.
ARQ Enable
– The Automatic Repeat reQuest (ARQ) mechanism is an optional part
of the WiMAX MAC layer and a protocol for error control in data transmission. When
a packet error is detected, the transmitter is automatically requested to resend the
packet.
HARQ Enable
– Hybrid ARQ (HARQ) is a variation of the ARQ error control
method. In standard ARQ, error-detection information (ED) bits are added to data to
be transmitted (such as cyclic redundancy check, CRC). In Hybrid ARQ, forward
error correction (FEC) bits are also added to the existing Error Detection (ED) bits
(such as Reed-Solomon code or Turbo code).
PKMv2 Enable
– PKMv2 (Privacy Key Management version 2) is the standard
security solution for WiMAX networks. The security protocol provides mutual
authentication of the subscriber station and base station, as well as distributing
traffic encryption keys. It is also used to transport EAP (Extensible Authentication
Protocol) messages.
