Fitness Monitoring

• Central device is MP3 player• Wireless headset included• Expand functionality

– Speed, distance– Heart rate, respiration monitor– Temperature sensor– Pacing information– Location information– Wristwatch display unit– Etc.

• Total system load < 500 kbps• Synchronization may go faster

Personal Video

• Central device is video camera– Camera sensor, recording, display

• Stream video content SDTV, HDTV• Connect other devices

– Personal storage device– Playback device w/ large display– Remote beamfinder– Location information (meta data)– Mobile communications device (MMS)– Home media server (sync)

Technical Requirements

• There is no specific standard for BANs– Current standards come close for specific use

cases, not broad enough– Issues: power consumption, discovery, QoS– Support for very low power devices, sensors

• Target less than 10% power consumption for communications compared to total device

• Have single standard with broad range of supported data rate - scalability

BAN Requirements - Draft

• Distance 2 m std, 5 m special• Piconet density 2 - 4 nets / m2 • Devices per network max. 100• Net network throughput 100 Mbit/s max.• Power consumption ~ 1mW / Mbps

(@ 1 m distance)

• Startup time < 100 us, or< 10% of TX slot

• Latency (end to end) 10 ms • Network setup time < 1 sec

(after initial setup, per device)

Process from ideas to a new TG project

New ideas are presented in the 15WNG Further discussions on the intentions and SG criteria by email

reflector, phone conference and WNG meetings. Check that the criteria for starting a SG are fulfilled.

If not the work item can be discarded or kept for further investigations / discussions.

• Create a motion to the 802.15 WG to start a SG to be approved by a straw poll. All attendees have voting rights.

• The WG to approve the SG motion.• The SG charter is to produce the PAR and 5C documents for

approval by the WG and ExCom.

Criteria for starting a Study Group

• Show that there is enough interest for a new SG– Recommendation:

some10 persons from at least 4 companies– Candidates for Chair and secretary

• Global definition of the intended project– Name– Features and Functions (what the should be supported) – Scope (what market, usage and technology)

• Check that there are no blocking issues from the SG charter– Show Reasons for a Broad Market Potential (MRD)– Identify Unique / Discriminating features (FRD) – Technical feasibility within the timeframe of the project – Indicate other requirements like Security, Regulatory, co-existence, No

blocking patents, etc. that may apply– Not same standards work is done by an other organization
