Wireless LAN - 802.11

Does NetSim Support 802.11 p ?
Yes, from v9.1 onwards. As per the latest release of 802.11, the standard 802.11p has been integrated with 802.11.  802.11p is a PHY layer sta...

How are packet collisions modeled in NetSim?
Packet Collision is a theoretical concept. In the real world a packet is not a "physical" entity that can collide. Therefore a "collision"...

How do I configure 802.11 simulation for RTS / CTS to work ?
The RTS / CTS mechanism is invoked when the packet size crosses the RTS threshold. And in general you would wish to use RTS / CTS only when transmitting dat...

In 802.11 can we monitor phy rate negotiation between access point and wireless nodes?
Yes this can be done. Enable packet trace and run the simulation (run it for short time because logging this file takes time, plus it would be a large ...
