Hi! I'm thinking to read bluetooth signal, but I need to sent and focus it as a beam, directionally. Is it conceptually possible to:
1. Focus bluetooth signal into a beam or
2. Screen transmitter in a way, than only little hole is left. Will that signal from the little hole fly only in one direction - forward, and will that lessen signal strength a lot on the receiver somewhere in the front?
Oh, I think I've found my answer finally. Direction antenna will do the trick.http://www.pentest.co.uk/documents/bt_dongle_mod/bt_dongle_mod.html
