The rural wireless networks are increasingly in demand by associations and autarchies to expand Internet access in this type of areas. The problem of such solutions centers not only in network deployment and its maintenance, but also in the equipment installation on clients, which always has big costs. This installation and configuration must be performed by a technician on site, so that the equipment can be integrated in the infrastructure. To try to mitigate this problem, it is presented a solution that allows the clients to install, with transparency, the device at home, reducing not only the cost for the management entity but also for the clients. This way, for info-excluded people or with new technology low experience level, it is the user that integrates himself in the network, making him part of the process, fostering the network usage.In this article are specified not only the system architecture but also the way that it works and how it obtains the desirable result. The tests made to the solution show the quickness, reliability and autonomy in the execution of the tasks, making it a benefit for rural wireless networks.This solution, by its robustness and simplicity, allowed an uptake to the IT by people who never thought to do it, namely an advanced age group (elderly) who want to join the world of the new technologies

According to the demands that calibration organizations need to calibrate various instruments and calibration requirements are complex, a kind of remote calibration system oriented to multiple objects and complex requirements is developed. The system architecture is designed. It’s based on B/S mode, and has the advantage that calibration operation can be done anywhere having Internet access. Then the requirement of remote control is realized. The objects and functions of the system are analyzed in detail, and the object models are built by using object-oriented idea and these models are realized by relation model whose related theories are mature. Then the operation commands can be defined flexibly and the problem that calibration requirements are complex is solved. The theory and experiment shows that the system can be used to calibrate various instruments, its operation command definition is flexible and calibration operation can be done anywhere having Internet access by using the system.
