July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 Prospective directions for TG 6 by considering different dimension parameters Huan-Bang Li, Bin Zhen, Shinsuke Hara, Tetsushi Ikegami, Jun-ichi Takada, Ryuji Kohno NICT, Japan Slide 2 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT

July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 Motivations • Tackle some basic questions for TG 6 – How many dimensions (parameters) do we need to consider? – Solutions need to stick to the PAR • Raise possible directions for solution – Allow multiple solutions. – Allow partial solutions. Slide 3 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT

July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 Dimensions To Be Considered • Operating frequency bands • Medical and non-medical applications • Low and high data rates • Wearable and implant BAN • Narrow band wide band technologies Slide 4 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT

July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 As They Are in the PAR (0575 -09 -0 BAN) Frequency bands ISM bands as well as frequency bands approved by national medical and/or regulatory authorities Applications a variety of applications including medical and personal entertainment Data rates data rates up to 10 Mbps is required Wearable and implant for use in close proximity to, or inside, a human body Narrow band or wide band technologies There is no restriction Slide 5 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT

July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 Candidate Frequency Bands (0034 -06 -0006) Slide 6 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT

July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 Frequency band vs. Data rates MICS (world wide) Low rate High rate 100 kbps 1 Mbps 5 Mbps BW≤ 300 k. Hz WMTS (regional) 8. 5 k. Hz<BW≤ 6 MHz ISM (world wide) selectable UWB (world wide) 10 Mbps BW > 500 MHz Slide 7 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT

July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 Medical vs. Non-medical Medical Non-medical MICS (world wide) YES NO WMTS (regional) YES NO ISM (world wide) YES UWB (world wide) YES Be cautious! 2. 4 GHz is crowded with 802. 11, 802. 15. 4, 802. 15. 4 a Coexistence may become an issue Slide 8 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT

July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 Application vs. Data rate Medical Nonmedical Low rate High rate MICS YES Maybe WMTS YES No ISM YES Maybe UWB YES Maybe ISM YES UWB YES Again, cautious on 2. 4 GHz Slide 9 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT

July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 Some Observations • Both world wide frequency bands and regional frequency bands (~ 802. 15. 4) • Technologies could be either wideband (e. g. FM-UWB) or narrow band (e. g. FSK). (Different technologies have different fits) • It would be difficult to use a single radio to meet all requirements (Multiple …) Slide 10 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT

July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 Possible Solutions • Solutions based on different radios on different bands. (multiple solutions) • No need for a single solution to meet all because of different requirements. (partial solutions) • Common MAC and upper layers are important for control and inter-connection. (Single MAC) Slide 11 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT

July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 Is It Reasonable? • Choices for markets and users trade off among different parameters • Many precedent standards 802. 11, 802. 15. 4 a • As “hinted” in PAR in close proximity to, or inside, a human body • One thing more to be kept in mind low power consumption is on the top requirements in TG 6 Slide 12 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT

July 17 , 2008 Doc: IEEE 802. 15 -08 -0528 -01 -0006 For Success n Get all candidate solutions on table for sounderstanding n Focus more on commonality for merge by sticking to the PAR n Compromise and harmonization Slide 13 Li , Zhen, Hara, Ikegami, Takada, Kohno, NICT
