Cannot open WLAN Link Modeling Example in Simulink

I am trying to open the example in the below URL: https://www.mathworks.com/help/wlan/examples/wlan-link-modeling-in-simulink.html

When I paste the HTLinkModelWLANExample in the command window; it gives me a message " >> Undefined function or variable 'HTLinkModelWLANExample'.

Please help if the example exists in 2017 Simulink library?

Thanks
