While standing in front of the brew station
I bet you can too.
However, my Computer is in a far distant corner of my huge old buildin from where my brewing station will be located placing the BCS a long way off in a stone walled room built with stones that have substantial iron in them. I've had issues with several wireless phones. The Panasonic 1.9GHz does pretty well though. I have no idea how a wireless router will perform
I have not contemplated adding a computer to the brewing station, though a cheap laptop might be the better approach. The idea of running around a few corners, through a couple rooms, up a couple flights of stairs, to my office where my PC is, and waking my PC up to tweak the controls is my idea of not having immediate manual control.
