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,…

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

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
