I've been searching the net but to no avail. How does Bluetooth work? I'd like to know more about its technical specs I hope there are some of these techies up here who know more than I do..
What part of the spectrum do they use, the signals seem to penetrate walls. And if it's only radio wave, how does it differ from ordinary radio wave? What kind of multiplexing is used (time or frequency or what?) to distinguish signals? What kind of modulation is used? If everyone's promoting Bluetooth as the "next generation" communication method, how is it superior to the radio wave that we have long been using?
Thanks in advance!
