area networks (BAN)]Purpose: [To provide some application examples for BAN]Notice: Possible enhancements compared to 802.15.4 are

summarized



Agenda• Scenario 1 : In Music CD store• Scenario 2 : At the Art Gallery• Scenario 3 : On the bus stop • Scenario 4 : In the car• Benefit• Direct use of 15.4 MAC into the that

of BAN?



Scenario 1 : In Music CD store• Browsing music samples• Scenario Flow

– When Young Hyeog enters a music CD store, he receives a BAN capable headset (or he is wearing his BAN capable headset already)

– Finding several interesting new albums, he is feeling like trying selected sample tracks

– Touching music albums, he can enjoy some sample tracks through BAN capable headset



Scenario 2 : At the Art Gallery• Listening to the explanation of

the art at the museum• Scenario Flow

– Entering Van Gogh Museum, Eunkyo receives a BAN capable headset (or she is wearing her own BAN headset already)

– Under each picture frame, a BAN user interface, e.g. a button, is available

– She can listen to the explanation of a piece of Van Gogh’s work by touching the button



Scenario 3 : On the bus stop• Listen to the bus schedule

information, e.g., bus number for certain destination, arrival time etc, at the bus stop

• Scenario Flow– Donghee has his own BAN device– He searches the destination information

and his schedule (possibly any map data) in the web with BAN capable laptop and download into the BAN device

– When he arrives a bus stop, he touch a button at the stop.

– Then he can listen to the explanation of bus information for his destination



Scenario 4 : In the car• In the car, BAN device can

transmit user preferences data such as seat angle and handle position, then car system operates properly according to the downloaded data when a user sits.

• A person can configure his/her preferences using BAN capable laptop or mobile device etc and download data to the BAN device

User preference configuration

Car ManagementSystem



Benefit• Ultra Low Power

– Consume about 5% of Bluetooth power based on internal experimental results

– User can enjoy the long-time battery life, e.g., for listening to the music (scenario 1)

• Easy to Use and Very Convenient– Don’t need to take something out or to write/input information since BAN

interacts directly with human – Consequently, user interface, e.g. touch screen, is very user-friendly

and convenient (scenario 2 and 3)• Custom made information based on the preference of each

individual can be extracted from the BAN – Recently user preferences become more emphasized– In consequence, BAN can interact with other outside networks to reflect

each individual’s preference, (e.g. car operation initialization as described in scenario 4, user-oriented output as depicted in scenario 3)



Thoughts• Analyzed benefits from several use cases are

actually high-level requirements to be achieved in the BAN

• Re-use of currently available 15.x MAC in the that of BAN would be considered to meet the requirements in the BAN

• Initially, 15.4 MAC could be considered one of candidates for the use of that of BAN because of its low-power nature, however, some challenges should be resolved.



Direct use of 15.4 MAC in the BAN?

IEEE802.15.4 BAN

Data rate Low

(20~250kbps)

High

(up to 10Mbps in case of Music Streaming)

QoS Scalability

Low

(Only up to 7 Guaranteed time slots)

High

(Medical scenario needs more guaranteed slots)

QoS Differentiation

None Needed

(Multiple scenarios need different level of QoS )

Security Simple More Needed

(To pay with BAN device or to enter a room with human touch or to handle personal information etc.

Safety None Needed

(Effect on human body should be considered)
