I installed a B&O house wireless system when the products were new to the market. Living room, den, bedrooms and kitchen, and at some expense.
The wireless signals or devices had problems with other appliances in the house. You might think of a room having one wireless " field " and what can happen when another appliance ( cellphone, microwave oven, computer, keyboard, etc. ) is then introduced into the same field. I call it the Theremin effect, as in the 1928 instrument . It was first an annoyance, starting with scratchy or zapped music, and then when we lost calls, a real pain.
As M-L products were also coming more into line, we decided to yank the wireless and make, and pull our own ML cable runs. We found a buyer for the wireless modules, and the expense of the cabling was in comparison next to nothing. Lee at Lifestyle AV provided very smart BOSCOM wall plates to connect rooms and floor levels, and make the overall job finish look better. The B&O speaker sound in all rooms is as one would expect, clean, constant, and not subject to interference. This includes the telephones as well.
Perhaps the newer modules have eliminated this problem, but given the new devices on the market each moth, and the frequencies utilized, I doubt it. Take this as helpful information.
If it works for you, go for it. If not, plan it out very well before plunging in.
