Maintenance of industrial infrastructure, machinery and communication is becoming a more and more critical issue in our society. The technology development in sensors and sensor networks will enable the embedding of "intelligence" into infrastructure, machinery and communication. Here Internet will become the communication paradigm to build on and already available communication infrastructure like the mobile phone networks will become the access network infrastructure. I will discuss such technology development including its capability for autonomous integration into its environment and autonomous operation. Thus enabling device and system diagnosis made available.
