Cinema HD bluetooth interrupt

Question

My Cinema 30" is interrupting the bluetooth signal from my MBP. I think.
The problem is that whenever I connect the Cinema HD 30" the Magic Mouse lags and jerks, in other words, the mouse becomes totally useless.

I have read that Mac Pro is/was causing interruption of the bluetooth signal because of the metal casing. I wonder if this is also the case for Cinema displays with aluminum enclosure?
Anybody else have this problem with Cinema HD aluminum enclosure?

Answer 1

You're idea of an external antenna would work, but it assumes the BT antenna are not integral to the printed circuit board and have instead some kind of antenna jack that can be plugged into. Then you'd have to find a wifi antenna with the right plug on it (wifi and BT are on the same spectrum, so the same antenna types can be used).
2.4 GHz can also be bounced off a mirror to pretty good affect. But you need a large-ish mirror, like a vanity mirror as might be found on a bathroom medicine cabinet. The mirror has to be outsized when compared with wavelength, so 18 inches would be sort of a minimum dimension to be considered for a mirror. But a mirror or two placed strategically at a 45º angle could work.
Assuming the desk or table is up against a wall, you could also try a big piece of aluminum foil on the back wall. Buy the widest roll you can find at the store. You wouldn't want to necessarily be looking at foil on the wall, but if it worked, you could put a poster or fabric or something like that over the foil.
Also, if everything is sitting on a table, you could put a big sheet of foil on the underside of the table to help confine the radio energy to the plane it's needed in. Maybe all silly ideas, but worth a try.
