nrf51822 Operating Range

Question

I was trying to find nrf51822's operating distance range (max) in the Bluetooth LE mode. Couldn't find any from the documentations. 
 Any theoretical numbers and/or practical observed would be highly appreciated.

The overall range of a RF device is very hard to calculate, as there are many factors that come into play. 
 This list can go on and on. Another thing about RF is that you will have reflections, and obstacles (like concrete walls etc) that comes into play when talking about range.
With an optimal tuned design, both antenna and output power, you will see around 20-25 meters in an office environment, depending on master used (phone, our dev dongle, BT4.0 usb dongle, etc.)
