Large-scale deployment of sensor networks is more and more becoming an issue to researchers and industry alike. The recently revised BTnode architecture provides two wireless radios and facilitates the interconnection of heterogeneous devices. Apart from offering interesting new opportunities in using multi-frontend devices in sensor-network research, this(More)

A two stage cascode low noise amplifier using tapered inductors with optimized quality factors was designed in a 130 nm logic CMOS process. The K-band (24 GHz-26.5 GHz) LNA consumes 11.25 mW DC power for a supply voltage of 1.5 V, achieves 27.5 dB peak transducer gain and 3.88 dB noise figure (NF) at 25 GHz. S11 and S22 at 25 GHz are -13 dB and -10 dB,(More)
You cannot see what is going on inside the network • setups typically involve lot's of cables for direct node access • debugging and monitoring messages interfer with operation • connection not possible to all nodes • coordinated methods and tools for deployment are missing today JAWS enables direct wireless access to every node Virtual Connections Host(More)
Bluetooth devices are organized in master-slave configurations known as Piconets. Up to seven slaves can be active in one Piconet. Multiple Piconets can be interconnected into a Scatternet using nodes in MASTERSLAVE state. Current Bluetooth devices have properties that need to be taken into account when designing and implementing algorithms: • While in(More)
