Physical layer for the IEEE 802.11 models. Its external interface (including gates and how it communicates with other modules) is the same as the Radio module's.
The implementation is largely based on the Mobility Framework's SnrEval80211 and Decider80211 modules.

Name | Type | Description |
---|---|---|
Ieee80211Nic | compound module |
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. |
Ieee80211NicAdhoc | compound module |
This NIC implements an 802.11 network interface card in ad-hoc mode. |
Ieee80211NicAP | compound module |
This NIC implements an 802.11 network interface card, in an AP, using infrastructure mode. |
Ieee80211NicAPSimplified | compound module |
This NIC implements an infrastructure mode 802.11 network interface card for a wireless Access Point (AP), but using a simplified mgmt module that does not support handovers. |
Ieee80211NicSTA | compound module |
This NIC implements an 802.11 network interface card, in a STA, using infrastructure mode. |
Ieee80211NicSTASimplified | compound module |
This NIC implements an infrastructure mode 802.11 network interface card for a host (STA), but using a simplified mgmt module that does not support handovers. |
Name | Type | Default value | Description |
---|---|---|---|
channelNumber | int | 0 |
channel identifier |
transmitterPower | double | 20mW |
power used for transmission of messages (in mW) |
bitrate | double |
(in bits/s) |
|
thermalNoise | double | -110dBm |
base noise level (dBm) |
pathLossAlpha | double | 2 |
used by the path loss calculation |
shadowingDeviation | double | 0dB |
used by the shadowing model calculation |
snirThreshold | double | 4dB |
if signal-noise ratio is below this threshold, frame is considered noise (in dB) |
sensitivity | double |
received signals with power below sensitivity are ignored |
