2. Comments on suggested bands of 5C and PAR for PSC Cheolhyo Lee, Hyung-Soo Lee (ETRI) <C. Lee, H. Lee, S. Choi>, <ETRI>

3. Draft 5C and PAR • PAR 5.2 Scope: This standard defines the PHY and MAC specifications optimized for personal space communications, for dynamically scalable data rates from 10 kbps to 54 Mbps, principally operating in a range of 30 meters or less with a capability of extension through relays in the 2.4GHz and 60GHz unlicensed bands. It provides mechanisms to coexist with other IEEE 802 standard technologies. It supports features including dynamic grouping with up to five concurrent n-to-m communications, locating of devices with accuracy of 10cm circular error probable (CEP), less than 20ms latency, fast synchronization with less than 500usec lock time for fast association of devices, soft handover for mobile devices, dynamic topology configuration, and enhanced security. (More information regarding this project is provided in Section 8.1.) <C. Lee, H. Lee, S. Choi>, <ETRI>

4. Draft 5C and PAR • 5C a) Substantially different from other IEEE 802 standards Existing standards can serve parts of the PSC system, but no single standard supports all combinations of simultaneous use of multiple channels, dynamic scalability of data rates, QoS (reliability and latency), low power consumption, fast device synchronization and association, device management, security control and configurability of topologies adaptable to new services required to address the variety of personal space applications i) Dynamic scalability of data rates ii) Fast, easy and simple association iii) Concurrent broadcasting of multiple various rate multimedia streams iv) Multi-peer group communication v) Low latency b) One unique solution per problem (not two solutions to a problem) The PSC Standard will consist of one Medium Access Control and Physical Layer per problem. The standard will address a unique solution for PSC in free space. c) Easy for the document reader to select the relevant specification The proposed PSC standard will be a distinct document with clearly distinguishable specifications <C. Lee, H. Lee, S. Choi>, <ETRI>

5. 2.4GHz Band • 2400~2483.5 MHz • Worldwide unlicensed ISM band • Slightly different regulations but common frequency bands sharing 2400-2483.5GHz • Crowded bands with WLAN, Bluetooth, ZigBee 2360 2400 2500 MHz USA/ Canada ISM ISM Europe Japan ISM Korea 2400 2483.5 <C. Lee, H. Lee, S. Choi>, <ETRI>

6. 5GHz Band • 5725-5875 MHz (ITU-R) • Worldwide unlicensed ISM band • Slightly different regulations but common frequency bands sharing 5770-5850 MHz 5650 5770 5925 MHz 5725 5850 USA ISM ISM Europe Japan ISM Korea 2400 2483.5 <C. Lee, H. Lee, S. Choi>, <ETRI>

7. 3.1 – 10.6 GHz UWB Bands • 3.1-4.8GHz, 7.4-9GHz : for UWB devices • Low band (3.1-4.8GHz) : allowed to use with DAA (Detection and Avoidance) not to interfere with mobile communications and broadcastings • High band (especially for 7.4-9GHz) : worldwide unlicensed band without protection requirements <C. Lee, H. Lee, S. Choi>, <ETRI>

8. 60GHz Band • USA/Canada has the same regulation • Common frequency band to sharing across countries • Slightly different emission power level 56 57 58 59 60 61 62 63 64 65 66 GHz Australia 59.4 62.9 USA/ Canada Unlicensed band Japan Unlicensed band Europe Unlicensed band Korea Unlicensed band <C. Lee, H. Lee, S. Choi>, <ETRI>

9. Considerations of Frequency Bands • 2.4GHz and 60GHz is the only solution? • Unlicensed band - Worldwide available bands : 2.4GHz, 5GHz, 3.1-10.6GHz(High band), 60GHz <C. Lee, H. Lee, S. Choi>, <ETRI>

10. Suggestion for draft • Suggestion for extend scope in PAR • Instead of specifying exact frequency band, open to all unlicensed bands in PAR as following 5.2 Scope: This standard defines the PHY and MAC specifications optimized for personal space communications, for dynamically scalable data rates from 10 kbps to 54 Mbps, principally operating in a range of 30 meters or less with a capability of extension through relays in the unlicensed bands. It provides mechanisms to coexist with other IEEE 802 standard technologies.
