I work at the reception and when a customer comes in who wants to see a colleague, I have to go to the back and tell him that he has customers at the counter. Now my question is: Can I have the first loudspeaker with me (as a microphone) and the second (approx. 15-20m) in the back of the open-plan office as a loudspeaker (wireless)? Or do you have another idea for a solution and if possible wireless (Bluethoot / WLan)?
