Ultra-wideband (UWB) technology enables high data-rate short-range communica-
tion, in excess of hundredmegabit-per-secondsand up to multi-gigabit-per-seconds,
over a wide spectrum of frequencies, while keeping power consumption at low lev-
els. This low power operation results in a less-interfering co-existence with other
existed communication technologies (e.g., UNII bands).
In addition to carrying a huge amount of data over a distance of up to 230 feet
at very low power (less than 0.5mW), the UWB signal has the ability to penetrate
through the doors and other obstacles that tend to reflect signals at more limited
bandwidths and higher power densities.
Microengineering and Microelectromechanical systems (MEMS) have very few
watertight definitions regarding their subjects and technologies. Microengineering
can be described as the techniques, technologies, and practices involved in the
realization of structures and devices with dimensions on the order of micrometers.
MEMS often refer to mechanical devices with dimensions on the order of
micrometers fabricated using techniques originating in the integrated circuit (IC)
industry, with emphasis on sILIcon-Based structures and integrated microelectronic
circuitry. However, the term is now used to refer to a much wider range of
microengineered devices and technologies.
