1. A node for controlling power allocated within a network, the node being a master in the network, and the network having a plurality of channels used by a primary system for communication, the node comprising:

  • a first communication interface comprising an interface between the node and a server;

    a second communication interface comprising one or more wireless interfaces between the node and respective ones of one or more other nodes, the one or more other nodes being slaves of the node;

    a memory in which a program is stored; and

    a processor to operate according to the program stored in the memory to;

    receive from the server information indicating transmission power allocation for one or more of the plurality of channels selected for use as part of a secondary system, the transmission power allocation being dependent on a path loss between a reference point of the primary system and the secondary system, the path loss being dependent on a distance between the reference point of the primary system and the secondary system and on one or more frequencies respectively allocated to the one or more of the plurality of channels selected for use as part of the secondary system, and the reference point being determined according to position data for a service area of the primary system and being a point at which interference in the primary system due to the secondary system is the harshest, andset the transmission power of the node within a transmission power range indicated by the received information indicating transmission power allocation.
