May 2016 doc.: IEEE 802. 11-16-0678r0 Wearable Device Use Cases and Requirements for LRLP Date: 2016-05-16 Authors: Name Affiliations Address Phone email Yunsong Yang Huawei Technologies 10180 Telesis Court, STE 165, San Diego, CA 92121, U.S.A. +1-858-754- 3638 yangyunsong@huawei.com Zhigang Rong Huawei Technologies Huawei Technologies Huawei Technologies Ping Fang Zhiming Ding Yunsong Yang (Huawei) Submission Slide 1
May 2016 doc.: IEEE 802. 11-16-0678r0 Introduction Several indoor and outdoor use cases have been proposed in LRLP TIG [1, 2, 3, 4] Wearable devices (WDs) are considered as a main target area for IoT. o A primary design consideration for wearable devices is low power. In this contribution, we present the following use cases involving wearable devices and discuss the requirements associated with them: o Wearable augmented reality (AR) devices o Wearable activity/health monitoring devices Yunsong Yang (Huawei) Slide 2
May 2016 doc.: IEEE 802. 11-16-0678r0 Wearable AR devices use case Description o A consumer wearable device supports augmented reality(AR) applications. Low power Wi-Fi is used to tether the wearable AR device with a smartphone for connecting to the Internet and Cloud. Requirements o Support of high data rate and throughput up to tens of Mbps. o Support of low latency. o Support of low transmission power to mitigate potential impact on eyes and to prolong the battery life.

May 2016 doc.: IEEE 802. 11-16-0678r0 Wearable activity/health monitoring devices use case Description o A user wears activity and health monitoring devices. Low power Wi-Fi is used to tether these wearable devices with a smartphone for connecting to the Internet and Cloud. Requirements o Support of low transmission power To limit the signal coverage in order to mitigate eavesdropping To prolong the battery life on WDs o Support of user privacy protection at Layer 2 To prevent leaking user private information To prevent user tracking Yunsong Yang (Huawei) Slide 4
May 2016 doc.: IEEE 802. 11-16-0678r0 Competitiveness against other technologies Comparing to BLE/ZigBee o 802.11 supports higher data rate and throughput, which is desirable for AR applications o 802.11 is perceived to be more secure Comparing to cellular o 802.11 supports higher data rate and throughput with lower total cost of ownership (TCO) than cellular based solutions o 802.11 with low power enhancement can achieve lower power consumption than cellular Yunsong Yang (Huawei) Slide 5
May 2016 doc.: IEEE 802. 11-16-0678r0 Summary We have presented two wearable device use cases for LRLP. We have also proposed the following requirements associated with these use cases: o Support of a wide range of data rates and throughputs, up to tens of Mbps o Support of low latency o Support of low transmission power To lower power consumption and prolong the battery life To limit the signal coverage in order to mitigate eavesdropping o Support of user privacy protection at Layer 2 To prevent leaking user private information To prevent user tracking Yunsong Yang (Huawei) Slide 6
