P06501 : ABOUT ZIGBEE TECHNOLOGY 2005 5 Engineers : 2 CE, 3 EE Sponsors : Sensorcon, PCB Express Advisor : Dr Hu, Dr Reddy

Problem : Crossbow Technology provides wireless sensor motes but cost deters the creation of large networks

Requirements : Sending commands to the network, receiving messages from the connected mote and display the real time network topology

Solution : Create low cost ZigBee Data Forwarding Unit (DFU) hardware and software prototype

P06501 : ABOUT ZIGBEE TECHNOLOGYWhy :

Low-powerLow-costUse of standard (Protocols and

Hardware)Results : 3 concepts have been studied, only one until the end Life-time calculations : more than 4 years The final project works Open-Source, Open-Architecture

Conclusion : This project match with our project, the low-power is very useful. The only problem is the range, which is 30ft outdoor. Is it possible to go further with this technology?

Lessons Learned : Find different solutions for the same

problem Low-power implies sleeping devices :

how to transmit data to sleeping devices Most important : separate each part of

the project in sub-projects, hence the need of good modularity (interface device/device)
