Over the past ten years there has been a revolution in the devel-
opment and acceptance of mobile products. In that period, cel-
lular telephony and consumer electronics have moved from the
realm of science fiction to everyday reality. Much of that revolu-
tion is unremarkable – we use wireless, in its broadest sense, for
TV remote controls, car keyfobs, travel tickets and credit card
transactions every day.
資源簡介：Short-Range communications is one of the most relevant as well as diversified fields of en- deavour in Wireless communications. As such, it has been a subject of intense research and development worldwide, particularly in the last decade. T...
