3. doc.: IEEE 802.15-12-0260-00-0ulp Submission Scope and Need Scope Applications of the IEEE 802.15.4 are very power aware and demand higher battery life. Existing physical layer of IEEE 802.15.4 is a low power physical layer. However, lot of new physical layer techniques have evolved over the period with ultra low power capabilities. This amendment defines ultra low power physical layer operation in the available 2.4 GHz spectrum, supporting typical data rates in the xx bits per second to yy bits per second range, to realize optimal and power efficient device command and control applications. The power consumption should be of the order of zz mW @ 0 dBm transmi power. Need The wireless sensor’s battery life is decided by the active power and duty cycle of the access mechanisms. Current generation of applications in sensor networks are very concerned on both form factor and power consumption. These requirements of sensor networks will be staisfied by designing a new ultra low power physical layer for globally available spectrum. 3 May 2012 Kiran Bynam, Samsung Electronics

4. doc.: IEEE 802.15-12-0260-00-0ulp Submission Broad market potential Broad sets of applicability –There are many existing 802.15.4 based low data rate command and control applications, wireless sensor applications such as indoor and outdoor control applications, that can benefit from the advantages offered by a ULP Physical Layer that can provide a smaller form factor and better battery life Multiple vendors and numerous users –The PHY proposed can be easily implemented by the existing technologies and hence multiple vendors can adopt this technology easily. There are many users as well for sensor network applications Balanced costs –The proposed amendment can be implemented with significantly smaller costs compared with the cost of the sensor itself 4 May 2012 Kiran Bynam, Samsung Electronics

6. doc.: IEEE 802.15-12-0260-00-0ulp Submission Distinct Identity Substantially different from existing standards –The amendement will propose a PHY that consumes power approximately much less than existing PHY One unique solution per problem –This amendment gives an unique solution that can operate with a very low power compared to IEEE 802.15.4 2.4 GHz OQPSK Physical layer. IEEE 802.15.4k TG is proposing a PHY optimized for the critical infrastructure monitoring supporting very lower data rates and long distance. This amendment will focus on the new physical layer for wireless sensor networks with a range of xx m (30 m) and work with thin batteries for a long period of time with data rates comparable to the existing IEEE 802.15.4 2.4 GHz Physical layer Easy for document reader to select PHY –As a different section, it is easy for document reader to identify the new PHY 6 May 2012 Kiran Bynam, Samsung Electronics
