Methods and approaches Define sub tasks and delegate
to each sub team Take part of previous research
and reports on secure wireless networks
Talk to Sermed & Alberto at KTH, and Patrick & Per at Kista BA

Wireless Network Advantages
No need for plugin Upgrading flexibility Allows set up where wires cannot
be easily installed – older buildings, asbestos in walls etc.
Disadvantages No special security technology IEEE 802.11b supports upto 11
Mbit/s

Radiation Wireless network output power
Recommended limits set by IEEE, NCRP, IRPA/INIRC
Radiation within the recommended limits
Decrease by the square of distance to the source
Cell phone – up to 600 mW AP / WLAN card – 100 mW in
Europe

Radiation – cont’d Health risks
Main risk – heating of the body Very large doses => risk of cell
mutation increases Conclusions
Comparably low output power => no large risk of radiation damages
Research is at an early stage – hard to foresee effects of long-term radiation exposure

Next steps… Extend the prototype within
the building Investigate whether to extend
it outside the building or not Is it possible to make the
community wireless in the future?
