BACKGROUND

• Wireless communication– Short range, LDR– Small, portable devices– Low power, low cost– Robust and reliable

Lower power, lower cost, smaller, more portable, more robust…

BAN, PAN, WSN…




Submission

MAGNET BEYOND STANDARDISATION TASK FORCE

• MAGNET Beyond partners– 34 partners from around the world. Experts on PNs.

• MAGNET Standardisation Task Force (MSTF)– Promotion of the results of MAGNET for standardisation towards the realisation of the

mass market potential of PNs.

• PAN/BAN optimised air interfaces– The MSTF seeks to standardise PAN/BAN optimised air interfaces and potentially higher

layers as well.

• MSTF members supporting air interface standardisation– Nokia, Philips, CEA-LETI, CSEM,…

Focus on LDR in this presentation

PN User

A Personal Network (PN) is a new paradigm extending the concept of a Personal Area Network (PAN), to allow users secure access to all their personal devices and services regardless of geographical location

PN devices can be separated by hundreds of kilometers, and still belong to the same PN

PNs encompass all connection technologies, short and medium range radio, infrastructure wireless networks or any future broadband wireless technology

MAGNET BEYOND AND PERSONAL NETWORKS

Private PAN

PNs represent a potential mass market for short range wireless personal sensor devices

MASS APPLICATION DOMAINS

• Home/Daily life applications

– Office environment

– Smart shopping

– Smart at home (sharing PN’s)

• The Health sector

– Patients, doctors, nurses, friends at home, hospitals or on the move

– Ambulance, emergency and medical staff on the move

– Monitoring patients anywhere

• Distributed work

– Journalists/mass media

– Students work situation

– Cooperative research

Patients Personal Network

Patient’s friend

Patient’s P-PAN

Home Network

Doctor’s PAN

Hospital Network

Internet

Not one killer application, but an aggregation

WHY A STANDARD?

• The need– A mass market standard for future UWB LDR devices

• The opportunity and market relevance– Multitude of simple, short range, LDR devices

• The benefits – Commercial and practical

• What is in it for us?– Unlocking the potential of, for example, LDR FM-UWB and realisation

of PN optimised solutions
