Re: Can you hear me? I'm on the train.
Using anechoic chambers for RF testing is standard practice. It's pointless the researchers saying 'we could do this at ten metres in a standard office environment' because there is no such thing. Other researchers have an idea from previous research of how results in an anechoic chamber might translate to to an open plan office with stud walls of material X, containing 3 routers, 15 laptops, 10 desktops of which 5 are using g Bluetooth keyboards, a microwave oven and 20 mobile phones etc etc etc
It's about minimising your variables.
