Amendment Standard – Superseded. This amendment to IEEE Std 802.15.4(TM)-2011 specifies a PHY for use in equipment intended to address rail transportation industry needs and to meet US positive train control (PTC) regulatory requirements and similar regulatory requirements in other parts of the world. In addition, the amendment describes only those MAC changes needed to support this PHY.
