The displayed items on this screen can be described as follows:
Center Frequency — Displays the center frequency used by the WiMAX service.
Bandwidth — Displays the channel bandwidth.
Customize — Displays a value used for compatibility with different base stations.
Radio Parameter — Selects the supported WiMAX radio band.
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.
ARQ Enable — The ARQ (Automatic Repeat reQuest) 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.
