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

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

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

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

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
