// This is an example to show how to configure an IEEE 802.11 Wi-Fi
|
|
// network where the AP and the station use different 802.11 standards.
|

//
|
|
// It outputs the throughput for a given configuration: user can specify
|
|
// the 802.11 versions for the AT and the station as well as their rate
|
|
// adaptation algorithms. It also allows to decide whether the station,
|
|
// the AP or both has/have traffic to send.
|
|
//
|
|
// Example for an IEEE 802.11ac station sending traffic to an 802.11a AP using Ideal rate adaptation algorithm:
|
|
// ./waf --run "wifi-backward-compatibility --apVersion=80211a --staVersion=80211ac --staRaa=Ideal"
