1 doc.: IEEE /1317r1 Submission November 2010 B.Carney, OakTree WirelessSlide 1 “L 3 ” * Update From September Date: Authors: *LONGER Range LOWER Data Rate LOWER Energy/Power Wi-Fi for the “Internet of Things”

2 doc.: IEEE /1317r1 Submission Background September “The Internet of Things” (10/1120r0) OakTree Wireless Consulting is engaged in a number of projects on behalf of clients with diverse businesses where connectivity provides important new functionality for core product lines This work has provided interesting insight into some common market requirements for new applications, not optimally serviced by today’s Wi-Fi offerings OakTree is initiating industry discussion about how to best enable this market and these applications for the rapid adoption of based technology Progress since September November 2010 B.Carney, OakTree Wireless2

3 doc.: IEEE /1317r1 Submission General Comments and Questions From September WNG Discussion (WNG Minutes 10/1138r0) Good interest in the topic, particularly as relates to power consumption What are current capabilities within IEEE specs? What are current industry product capabilities? Other groups to share this thinking with? Where is the best arena to gain traction? What to do next? November 2010 B.Carney, OakTree Wireless3

4 doc.: IEEE /1317r1 Submission What are the Problems Under Consideration? Inconsistent industry implementation of power management features creates potential interoperability issues and inhibits best possible power conservation –Not all APs buffer data uniformly, retain associations for the same duration, etc… –Inconsistency in Power Save functionality, etc… –Wi-Fi Industry should explore a certification program that improves network power management based on capabilities described within existing/in-progress specifications While the specifications already have inherent abilities for improved network power management and station power conservation, other wireless technologies are perceived to be better choices for very low power use cases. –Zigbee, BTLE are examples, targeted specifically at Low Power applications –Wi-Fi industry lacks a wider awareness of Wi-Fi’s suitability for use in such applications –Wi-Fi Industry should take necessary steps to demonstrate and communicate that specific industry- certified solutions exist for improved power management, particularly for STA devices Uniform industry implementation of key power management related features is today an interoperability question, but most importantly, an opportunity that can open new markets for low power Wi-Fi applications November 2010 B.Carney, OakTree Wireless4

5 doc.: IEEE /1317r1 Submission Current Directional Thinking (1) ‘Internet of Things’ unique market requirements are tightly coupled, with better ability to manage STA power consumption uniformly, being the highest priority –Range and rate are some variables that also affect power Not considering “Low Power Wi-Fi” technology development, rather, investigate the prospects for a certification program that will enable the best possible network power consumption, especially for STAs requiring the greatest control of energy consumption –E.g., “Network Power Management” Certified Products –Similar to Wi-Fi Alliance’s WMM certification in that Power Conservation is yet another type of QoS November 2010 B.Carney, OakTree Wireless5

6 doc.: IEEE /1317r1 Submission Current Directional Thinking (2) Not concerned, at this moment, to produce new technical specifications or to define requirements for yet another amendment –Work done on this outside of may eventually produce some recommendations for future consideration by Not considering power consumption as an absolute performance requirement (i.e., not a power consumption test) –Only concerned with verifiable, uniform industry implementation of specified power management features within specs –May also develop recommended practices >> guidelines for AP/STA implementation to further improve upon a certification program requirements E.g., buffer size, security practices, ….
