18 http://2g1319.ssvl.kth.se/~mobileintranet/ Mobile Intranet Access 2002-05-29 18 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

19 http://2g1319.ssvl.kth.se/~mobileintranet/ Mobile Intranet Access 2002-05-29 19 AP:s in the Building

20 http://2g1319.ssvl.kth.se/~mobileintranet/ Mobile Intranet Access 2002-05-29 20 General principle for security solution

21 http://2g1319.ssvl.kth.se/~mobileintranet/ Mobile Intranet Access 2002-05-29 21 VPN and Firewalls VPN IPsec Authentication Encryption Packet filtering

22 http://2g1319.ssvl.kth.se/~mobileintranet/ Mobile Intranet Access 2002-05-29 22 The Prototype

23 http://2g1319.ssvl.kth.se/~mobileintranet/ Mobile Intranet Access 2002-05-29 23 Outline Introduction Goals Method Resources Project Progress The Prototype Access points & Security Wireless Network – Pros & Cons Radiation Possible Extensions Video Conclusions Summary Questions

24 http://2g1319.ssvl.kth.se/~mobileintranet/ Mobile Intranet Access 2002-05-29 24 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

25 http://2g1319.ssvl.kth.se/~mobileintranet/ Mobile Intranet Access 2002-05-29 25 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

26 http://2g1319.ssvl.kth.se/~mobileintranet/ Mobile Intranet Access 2002-05-29 26 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
