This NIC implements an 802.11 network interface card. It can be configured via the mgmtType parameter to act as an AP or a STA, or for ad-hoc mode.
The following diagram shows usage relationships between types. Unresolved types are missing from the diagram.

Name | Type | Default value | Description |
---|---|---|---|
mac.address | string | "auto" |
MAC address as hex string (12 hex digits), or "auto". "auto" values will be replaced by a generated MAC address in init stage 0. |
mac.maxQueueSize | int |
max queue length in frames; only used if queueModule=="" |
|
mac.bitrate | double | ||
mac.rtsThresholdBytes | int | 2346B |
longer messages will be sent using RTS/CTS |
mac.retryLimit | int | -1 |
maximum number of retries per message, -1 means default |
mac.cwMinData | int | -1 |
contention window for normal data frames, -1 means default |
mac.cwMinBroadcast | int | -1 |
contention window for broadcast messages, -1 means default |
mac.mtu | int | 1500 | |
radio.channelNumber | int | 0 |
channel identifier |
radio.transmitterPower | double | 20mW |
power used for transmission of messages (in mW) |
radio.bitrate | double |
(in bits/s) |
|
radio.thermalNoise | double | -110dBm |
base noise level (dBm) |
radio.pathLossAlpha | double | 2 |
used by the path loss calculation |
radio.shadowingDeviation | double | 0dB |
used by the shadowing model calculation |
radio.snirThreshold | double | 4dB |
if signal-noise ratio is below this threshold, frame is considered noise (in dB) |
radio.sensitivity | double |
received signals with power below sensitivity are ignored |
