3. Motivations Tackle some basic questions for TG6
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.

4. Dimensions To Be Considered
Operating frequency bands
Medical and non-medical applications
Low and high data rates
Wearable and implant BAN
Narrow band and wide band technologies

5. As They Are in the PAR Frequency bands (0575-09-0BAN) Applications
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

6. Candidate Frequency Bands
( )

7. Frequency band vs. Data rates
Low rate
100 kbps 1 Mbps
High rate
5 Mbps Mbps
MICS (world wide)
BW≤300 kHz
WMTS (regional)
8.5kHz<BW≤6MHz
ISM (world wide)
selectable
UWB (world wide)
BW > 500 MHz

8. Medical vs. Non-medical
MICS (world wide)
YES NO
WMTS (regional)
ISM (world wide)
UWB (world wide)
2.4 GHz is crowded with , , , a
Be cautious!
Coexistence may become an issue

9. Application vs. Data rate
Low rate
High rate
Medical
MICS
YES
Maybe
WMTS No
ISM
UWB
Non-medical
Again, cautious on 2.4 GHz

10. Some Observations
Both world wide frequency bands and regional frequency bands
(~ )
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 …)

11. 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)

12. Is It Reasonable? Choices for markets and users
trade off among different parameters
Many precedent standards
802.11, , 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 TG6

13. For Success Get all candidate solutions on table for
sounder understanding
Focus more on commonality for merge by
sticking to the PAR
Compromise and harmonization
