I am the link quality very satisfied, especially when you consider that about 12 wireless router and several active Bluetooth devices to fight with me here in the vicinity at that moment to the frequency sovereignty. The stick logs with Atheros AR3011 actually in the USB devices. The datasheet of the chip manufacturer says clearly "Bluetooth Class 2 Radio" to this chip. The German Wikipedia says: "Class 2 = 2.5 mW, 4 dBm, approximately 50 meters (outdoors)." Up to 10m there is class 3. However, it is in fact also the 1 / 10th / 100m definition of classes 3/2/1 to find on the Web. Now to the practical: So I could in fact with the headphones without disconnection or noticeable disturbance in the "contaminated" Apartment 16 meters line of sight to the dongle (open doors) go - then came the wall ... any further test comes only after winning the lottery , By 2 walls were about 6-8m up there first short dropouts. (!) Conditions-for me that he certainly does not create 100m, but is at least a lot better than the 10m under ideal ... wants me there but not get involved in hair-splitting; enough for me that in any case completely out and I think a lot more can be of a Nano (!) - Stick also not expected.
For any (Driver) problems with other, more popular operating systems can I naturally say anything here. From me a strong buy recommendation for people who are planning a similar application under one of the newer Linux distributions.
