3. Table of Contents • What is PSC? • PSC applications • PSC features • Need for a new standard • Q&A

4. °C °C Personal Space Personal space A • The personal space is defined as a physical and virtual space which a person regards as psychologically the person’s. • For this standard, it is defined as a physical space where devices are controlled by or for the person, and among devices in this space of an individual. Public space Personal space B Personal space C

5. °C Personal Space Communication (1) • Connectivity between a person and the devices and among devices associated with the person in the personal space • Without human intervention in the personal space • For the exchange of information and management of the environment.

6. °C °C Personal Space Communication (2) °C Public space After more individuals entered into this public space Public space with more than one personal space (In this figure, three personal spaces) Public space with one personal space

7. PSC Applications (1) • PSC radio customized for Smart Phone • Traffic off-loading in hot spots • Worldwide data traffic explosion • Shopping mall, stations, café, campus, home, etc • Location-based services • Indoor navigation, advertisement push, • Kiosk, museum art pieces • Personal asset tracking • Coverage extension • Mobile terminal relay

8. PSC Applications (2) • PSC radio interacting with all devices in personal space • Voice/Video over PSC • VoIP, IPTV, Internet radio, Webcam, Smart camera, speaker, microphone, etc • Multi-lingual interpretation system, drive-in shop audio • Wireless tour guide • Requires group communications and localization of devices • Museum art pieces (location), explanation of individual’s own language (group comm) • Stereo karaoke • Requires low latency: tight lip synch on TV and speaker

9. PSC Applications (3) • PSC radio interacting with all devices in personal space • Interacting with ubiquitous devices (M2M, sensor/control network) • Home (home automation), office (personalized smart building), stations (information push), shopping mall (price check), street (traffic /air quality monitoring, public safety, navigation) • Using computer peripherals (printer, external hard drive, headset, monitor, projector) • Remote Controller (TV, DVD, CD, ..) • Group games

10. PSC Applications (4) • PSC radio provides both low and high rate communications simultaneously. • Examples • Personalized temperature sensing & control while watching personal video. °C

11. Example: coverage extensionMobile Terminal Relay Mobile Terminal Relay has been applied in 3G as: Benefits of Mobile Terminal Relay The demand is strong when terminal users are dense Improving both communication capacity and coverage extension No cost for Carriers *By China Mobile and Vinno Tech.

12. July 2010 Terminal Relay Protocol Stack Control Plane User Plane • Function of L1/L2 of the Terminal Relay PSC PHY/MAC • PCS can supports new telecom services.

13. PSC: the common interface to the environment a user moves into.

14. Frequency and duration of Applications Ref: 15-10-0169-01

15. Major Features to support PSC applications • Clean slate single standard solution • Not combo-chip solution • Dynamic scaling of a wide range of link rates • Low rate sensory data to high rate video (100kbps-50Mbps) • A wide range of QoS requirements • Real-time streaming video, periodic sensor data, reliable data, etc • High precision ranging • Fast association and synchronization • Multiple modes of communications • 1-1, 1-n, group communications

16. PHY Features • Dynamic scalable link rates • Wide range of link rates: 100 kbps to 50 Mbps • Wide range of energy constraint • Coverage of 30 meters • Link latency less than 20 ms • Localization/Ranging • Use of unlicensed bands including 2.4 GHz and 60 GHz °C

17. MAC Features (1) • Dynamic multi-rate access • Various link rate, various duty cycle with single bit-rate • 100kbps to 50Mbps • Asymmetry • All link rates: PSC on mobile phone • High rate: IPTV set-top box • Low rates: Ubiquitous device • Quality of Service Guarantee • Periodic sensor reading & control • Real-time streaming of voice/video • Asynchronous asset tracking / information push • Latency-critical and reliable broadcasting °C

MAC Features (4) • Co-existence & Co-operation with other PSC networks • Dynamic group communication • Fast joining / leaving • Fast synchronization Painting 1 English (Group 1, CH1) Spanish (Group2, CH2) Korean (Group3, CH3) …. Painting 2 English (Group 4, CH4) Spanish (Group 5, CH5) Korean (Group 6, CH6) …. Question?

21. MAC Features (5) • Coverage extension • Mobile Terminal Relay

22. Existing 802 standards • IEEE 802.11, 802.16, 802.22, 3G/4G • High power • IEEE 802.15.1 • Medium rate • IEEE 802.15.3 • MAC and High rate only • IEEE 802.15.4 • Low rate only • IEEE 802.15.5 • Separation of Low and High rate. • IEEE 802.15.6 • Short range (5 meters).

23. Need for a new Standard • Many devices in a personal space not interoperable. • Desirable to have a new solution with one technology not by combining multiple technologies into a combo chip. • Existing standards can serve parts of the PSC, but no single standard optimized for all features for PSC. • Therefore, there is a need for a new standard to serve the PSC applications.
