Pixhawk and Raspberry PI as Wifi access point

Hi,

Just wondering if anyone has any experience doing this?
https://pixhawk.org/peripherals/onboard_computers/access_point

If so, what kind of range should I expect and does the wifi connection disrupt standard 2.4GHz radio gear?

Looking to establish a connection between Qgroundcontrol running on an iphone or android tablet and the onboard Raspberry PI with mavlink and video streaming: https://pixhawk.org/peripherals/onboard_computers/video_streaming

Thanks
