Abstract: An arrangement is provided for facilitating remote monitoring and control of an independent target location. Physical level devices (106, 107, 108, 109, 110, 111, 112, 211) are adapted to at least acquire information at the target location. A transceiver (511) is adapted to exchange information with a remote central system. Between the physical level devices (106, 107, 108, 109, 110, 111, 112, 211) and the transceiver (511) there is a two-tier hierarchy of system elements. The two-tier hierarchy includes a multitude of nodes (221) and at least one controller module (231, 231?). Of these nodes (221) are connected to the physical level devices (106, 107, 108, 109, 110, 111, 112, 211), and the controller module (231, 231?) is connected to the nodes (221) and to the transceiver (511).
