The OPNET wireless module and the WLAN model provide high-fidelity modeling, simulation, and analysis of wireless networks, including the RF environment, interference, transmitter/receiver characteristics, full protocol stack, including MAC, routing, higher layer protocols and applications. Furthermore, the ability to incorporate node mobility and interconnection with wire-line transport networks provide a rich and realistic modeling environment. Some of the 802.11 features include:
- Support for 802.11a, b, e, g
- DCF / PCF MAC algorithms
- HCF EDCA mechanisms with TXOP frame bursting
- Support for QoS facility of 802.11e
- Optional block-acknoledgement and no-acknoledgement operations of 802.11e
- Exponential back-off – reduced collision probability
- Reliable data transmission via RTS-CTS exchange
- Fragmentation (threshold based)
- Mixed 11b/11g wireless LANs with CTS-to-self protection
- Interoperability of 11e and non-11e capable nodes
- Physical Layer: FHSS, IR, DSSS, OFDM, Extended Rate PHY-OFDM
- Auto-assignment of channels to BSSs (optional)
- Multiple data rates
- Various modulation schemes: DPSK, BPSK, QPSK, CCK, QAM-16, QAM-64
- Roaming
- Support for 802.11n is available through the OPNET Contributed Model Library
