I think he means "maxed out". And he apparently doesn't realise how much 
bandwidth is available around 2.4Ghz: for example between 2.4 and 2.5 
there's 5 times more bandwidth than the *entire* FM radio spectrum, or 
enough space for about 20 TV stations

Similar around here. With an effective range of about 2m, it will take a 
lot more than a typical office or apartment building to cause 
consistent interference over bluetooth
