We present a new methodology for the development, test, deployment, and 
validation of wireless sensor networks. Our approach is a robust, wireless 
cable replacement offering reliable and transparent connections to arbitrary 
WSN target devices. Compared to traditional serial-cable approaches, this 
results in enhanced scalability and flexibility with respect to node location, 
density, and mobility. This makes the coordinated deployment of WSNs possible. 
We describe the operation of this novel tool and discuss an exemplary 
implementation on the BTnode platform.
