Can't simulate mobile 3GSlow with scripting.

Hi,

Can some one help on how to simulate 3G slow network from scripting? following script is defaulting to 3G.

please help if there are any other location that supports 3Gslow network.

wpt.runTest(script,{
connectivity: “3GSlow”,
location: ‘Dulles_iPhone6’,
firstViewOnly: true,
runs: 1,
pollResults: 5,
video: true
},
