The standard IEEE 802.15.6TM –2012 Wireless Body Area Networks (BANs) aimed to solve issues related
to use cases of Human Body Area Networks (HBAN). The Amendment IEEE 802.15.6a addresses higher reliability of HBANs performance
and adds Vehicle Area Networks (VBAN) support.
The amendment enhances the Ultra-Wideband (UWB) Physical Layer (PHY) and Medium Access Control (MAC) to support higher dependability of HBANs and VBANs applications in high-density scenarios
while coexisting with other wireless systems operating in the UWB band.
Target areas of enhancement include protection against interference from BANs systems and other wireless systems operating within transmission range in the UWB band. A simple
and more reliable MAC protocol compared to IEEE 802.15.6.
Other areas of enhancement include mechanisms to support higher performance, security, coexistence, and efficiency in the operation and maintenance of HBANs and VBANs. The amendment
incorporates support for infrastructure protocols such as Time-Sensitive Networking (TSN) for reliable transmission of BAN information
across different networks.
VBAN applications operate under strict compliance to standards and limits for Electromagnetic Interference (EMI) from vehicle's electric and electronic systems.
The purpose of the amendment IEEE 802.15.6a is to provide an international standard for short-range, low power, secure, highly reliable
wireless communication system for use in proximity to or on the human body or vehicle body. Technical features offer to satisfy an
evolutionary set of entertainment, autonomous control, and healthcare services.
