Ploug, Danfoss A/SSlide 5 Present technologies We love 802.11 We look forward to 802.15.4 / ZigBee We see areas for Bluetooth Today we use proprietary technologies and are successful but not happy with all applications Do standards cover everything? No – that is why I am here We have applications with RF performance needs beyond present level

8. doc.: IEEE 802.15-03/491r0 Submission November 2003 O. Ploug, Danfoss A/SSlide 8 Tests We have done extensively testing on RF technologies –Several narrowband and several frequencies –Several WLAN’s –802.15.4 –nanoNET Have performed the tests in various environments –Industrial, commercial and residential –Internally and externally –Covered most application environments

9. doc.: IEEE 802.15-03/491r0 Submission November 2003 O. Ploug, Danfoss A/SSlide 9 Tests Tested different antenna types and placements Over 5000 transmission tests build our experience Some of you may know that we have established a Communication Technology Centre

13. doc.: IEEE 802.15-03/491r0 Submission November 2003 O. Ploug, Danfoss A/SSlide 13 Test headlines Existing technologies function very satisfactory for many applications There is clearly potential in linear FM as a spread spectrum technology Our tests show that performance is on the edge for “high end” applications with existing standard based technologies

14. doc.: IEEE 802.15-03/491r0 Submission November 2003 O. Ploug, Danfoss A/SSlide 14 What do Danfoss look for? Higher range Longer battery life / lower power consumption Higher robustness against multipath fading Coexistence with WLAN and Bluetooth

15. doc.: IEEE 802.15-03/491r0 Submission November 2003 O. Ploug, Danfoss A/SSlide 15 Summary Great existing standards We have applications that need more range and robustness We believe there are technologies that can fulfil the need We invite 802.15 to explore the opportunities
