IEEE 802.15.3a: 480Mbps Wireless Personal Area Networks
The recent UWB spectral allocation for unlicensed spectrum and the new definition of UWB adopted by the FCC have induced the leading UWB manufacturers to develop a new method of using the UWB spectrum. It is not based on impulse radios, but on a new concept of using multiple bands. This technique has several advantages, because the wireless transceivers employing this technique are more scalable, adaptive and have better co-existence levels with other system such as IEEE 802.11. A multi-band UWB system design in general yields many tangible benefits, including more scalable and adaptive than single band designs, better co-existence characteristics with systems such as 802.11a, and lower risk implementations because it leverages more traditional radio design techniques. These advantages can be retained while maintaining similar complexity and power consumption levels as single band designs.
