1 Feb. 2nd, 2005TinyOS Technology Exchange II The eyesIFX platform Vlado Handziski Technical University Berlin Filling in for: Thomas Lentsch Infineon Technologies, AG

2 2 TinyOS Technology Exchange II Feb. 2nd, 2005 Infineons eyesIFX Platform Developed by Infineon for the Energy-efficient self- organizing and collaborative wireless sensor networks project – EYES TI MSP430 microcontroller family 64 kbps 868MHz ASK/FSK Infineon Wireless Transceiver TDA5250 HW UART based byte interface towards the radio Integrated Temperature and Light sensors Full TinyOS software support provided by TU Berlin

3 3 TinyOS Technology Exchange II Feb. 2nd, 2005 eyesIFXv2 Node Architecture

4 4 TinyOS Technology Exchange II Feb. 2nd, 2005 The eyesIFXv2 Mote

5 5 TinyOS Technology Exchange II Feb. 2nd, 2005 TDA525x Block Diagram

6 6 TinyOS Technology Exchange II Feb. 2nd, 2005 TDA525x - Feature List Technology0.5µ 25GHz BiCMOS-Process Frequency bands315MHz (TDA5251) 433MHz (TDA5255) 868MHz (TDA5250) 915MHz (TDA5252) (from Q2/05) Data rate1..64 KBit/s Deviation / Mod. index KHz / mH > 2 SensitivityASK: < W, BER = 10-3 FSK: < W, BER = 10-3 Transmit powerPout up to W Supply voltage V Current consumptionTX: typ. 10mA RX: typ. 8 3V Power downmax. 100nA Temperature range-40°C / +85°C Self-polling with fast data rate detection easing CSMA protocol implementation, on-chip data and channel filters set via I²C or SPI bus

7 7 TinyOS Technology Exchange II Feb. 2nd, 2005 eyesIFXv2 Deployments TU Berlins WSN Testbed Testing WSN building automation applications in realistic setting About 50 instrumented rooms, more then 120 nodes spread on four floors of the TKN office building USB back channel allowing remote control and debugging

8 8 TinyOS Technology Exchange II Feb. 2nd, 2005 Summary Initially developed as research platform for the EYES project Targets the low-power end of the WSN application spectra Shows how the cost of the WSN platforms can be reduced by reusing designs from related high volume markets TDA 5250 family originally developed for the Remote key-less car entry application Node design influenced by Infineons wireless tire pressure measurement solutions eyesIFXv2 motes (868MHz) commercially available in Q2/05, after the end of the EYES project
