Hello everyone,

I am attempting to change the operating frequency to 300MHz (to simulate the working of 802.11af) but retain the overall PHY layer configuration of 802.11ac.

I have gone through earlier posts in this group and realized that the SetFrequency() function (in the class YansWifiPhy) can be employed. However, when I wish to implement this change by using the function -

NetDeviceContainer staDevices = wifi.Install (phy, mac, wifiStaNodes);

I get an error since the object phy is required to be of YansWifiPhyHelper datatype, not YansWifiPhy. However, I can't seem to change the frequency using the WifiPhyHelper class. How do I resolve this problem?

Hi,

first you must install the Wi-Fi stack on the node though the usual means. Only after that you can retrieve the WiFiPhy object from the node and change its operating frequency.
