Introduction - Purpose

1. To Plan and develop a secure wireless network in the main office building

2. Make an outline on the further development for other parts of the borough



2002-05-295

Introduction - Goals To fulfill the purpose Accomplished by dividing the

purpose into several clear and concrete subtasks



2002-05-296

Goals - Subtasks (Kista BA) Plan a 11 Mbps wireless network Develop a security solution Implement the wireless network Do an radiation analysis Do an extra analysis (Ibbe 16

cred) Benefits and opportunities Possible extensions Internet access from extensions



2002-05-297

Goals- Subtasks cont’d (KTH)

Produce progress reports Create a 3 minute video Write a final report Hold an oral presentation Participate in exhibition



2002-05-298

Unique Contribution A prototype that might be

exported to other boroughs in Stockholm

Adapted VPN and Firewall solution for security

Extendable – for example to Stockholm Open.net

Goals Method





2002-05-2916

Wireless Standards HiperLAN2 54 Mbps

Few products Telecommunication origin Real time video, multimedia and speech

IEEE 802.11a 54 Mbps Only the lower of the 5 GHz band Not allowed in Europe PTS permission in Sweden

IEEE 802.11b (WiFi) 11 Mbps Standard in use 150 m indoors 2.4 GHz band



2002-05-2917

Access Points models 3Com AP 6000, AP 8000 and 3Com Airconnect

Cisco Aironet 350 (IEEE 802.11X)

Orinoco AP 500, 1000 and 2000 (Lucent)

Symbol AP Spectrum 24

Xircom APWE 1100 (Intel)

Dell TrueMobile AP 1150 and 1170 (Orinoco)

Nokia A032



2002-05-2918

Dell & IEEE 802.11b Lucent Orinoco - one of the biggest

manufacturer of WLAN-products Making chip-set for AP WiFi-standard Approved for a long

time, many products Doesn’t disturb

radio links Dell is OEM-product Agreements with Stockholm Stad

Goals Method





2002-05-2924

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



2002-05-2925

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



2002-05-2926

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?
