Abstract
The contribution describes a survey of the IEEE Standard 802.15.6-2012 Body Area Networks (BANs), in special the UWB physical layer, and a coexistence study of such IEEE Standard UWB devices with other UWB systems, in particular IEEE STD 802.15.4a-2007 (pico-nets) devices and IEEE 802.15.4f-2012 (RFID) devices. Indeed, the recently published IEEE STD 802.15.6-2012 includes IR-UWB and FM-UWB technologies. The IR-UWB transceivers for BANs are based on the transmission of a single and relative long pulse per symbol (new paradigm in UWB) or a concatenation or burst of short pulses per symbol (legacy), while FM-UWB transceivers are based on the concatenation of a CP-GFSK signal and a wideband FM signal. Such systems are optimized for low power consumption and reliable operation, especially in medical applications. Furthermore, the UWB signal power levels are in the order of those used in the MICS band (implant devices like pacemakers), therefore providing safety power levels for the human body and low interference to other systems’ devices.
