Insert the following new paragraph at the end of 1.3: This standard also provides an international standard for an ultra-low complexity, ultra-low cost, ultra-low power consumption alternate PHY for IEEE Std 802.15.4(TM) (comparable to the goals for IEEE Std 802.15.4- 2003). To satisfy an evolutionary set of industrial and consumer requirements for wireless personal area network (WPAN) communications, the precision ranging capability will be accurate to one meter or better,and the communication range, robustness, and mobility improved over IEEE Std 802.15.4-2003. The requirements to support coexisting networks of sensors, controllers, and logistic and peripheral devices in multiple compliant co-located systems are addressed.
