    Abstract: A method of assigning radio frequencies to base stations (105-1) of a first radio telecommunications network operating in a first radio frequency band and co-existing with at least a second radio telecommunications network (110, 110-1;115, 115-1) operating in a second radio frequency band at least partially overlapping the first radio frequency band. The method comprises: simulations of electromagnetic field propagation; defining a cost function for quantitatively evaluating a radio frequency assignment plan for the base stations of the first radio telecommunications network; calculating an initial radio frequencies assignment plan for the base stations of the first radio telecommunications network; calculating at least one alternative radio frequency assignment plan starting from the initial radio frequency assignment plan; selecting as radio frequency assignment plan for the base stations of the first radio telecommunications network one of the alternative radio frequency assignment plans based on the values of the cost function, and assigning to the base stations (105-1) of the first radio telecommunications network frequencies in accordance with the radio frequency assignment plan selected.

    Abstract: A method (100) for managing a wireless network, comprising: collecting (105) a sequence of traffic data samples ordered in time, and arranging said collected data samples in at least one level-0 residual matrix having at least one dimension, said dimension of said level-0 residual matrix corresponding to a respective time scale comprising an ordered sequence of time units, said ordered sequences of time units defining a first time window; performing at least once a cycle, each n-th iteration of the cycle, starting from n=0, comprising a sequence of phases A), B), C), D), E): A) for at least one dimension of a level-(n) residual matrix, sub-dividing (110) the corresponding time scale in such a way to group the time units thereof in a respective level-(n+1) partition of time units so as to subdivide the traffic data samples in corresponding level-(n+1) traffic data sample sets; B) for each level-(n+1) traffic data sample set, calculating (115) a corresponding functional which fits said level-(n+1) traffic data sample set; C) for each level-(n+1) traffic data sample set, calculating (115) a corresponding approximation of the level-(n+1) traffic data sample set by applying the corresponding functional to the corresponding level-(n+1) partition of time units; D) joining together (115) the approximations of the level-(n+1) traffic data sample sets to calculate a level-(n+1) approximated matrix, said level-(n+1) approximated matrix being an approximated version of the level-(n) residual matrix; E) calculating (120) the difference between the level-(n) residual matrix and the calculated level-(n+1) approximated matrix so as to obtain a level-(n+1) residual matrix; forecasting (130) traffic data trend in a second time window different from the first time window by generating predicted data samples by applying the calculated functional to a partition of time units comprising an ordered sequence of time units corresponding to at least one among said second time window and said first time window; using (140) said forecasted traffic data trend to manage the wireless network.

    Abstract: It is disclosed a method for performing a time measurement on a packet flow transmitted through a communication network. The transmitting node divides the packets into first and second packets transmitted in alternating periods. At each period, transmitting node also marks each packet by setting a feature thereof to a first value indicating that the packet shall undergo time measurement or a second value indicating that the packet shall not undergo time measurement. The transmission times of two packets marked by the first value are reciprocally delayed by a predefined inter-transmission time shorter than a period duration. For each packet marked by the first value, the transmitting node generates a transmission time stamp and the receiving node generates a reception time stamp. Then, after the end of each period, a time measurement is performed based on transmission and reception timestamps of packets marked by the first value transmitted during the preceding period.

    Abstract: A system for managing house appliances supplied through a power grid is provided. Each house appliance operates according to at least one corresponding operative mode. Each operative mode comprises a sequence of operative phases. The system comprises at least one control unit interfaced with the house appliances for exchanging data. The at least one control unit collects power profile data comprising timing and electric power consumption data of each operative phase of each operative mode of the house appliances; generates a time schedule of the house appliances operations by distributing in time the execution of the operative phases thereof such that total power consumption of house appliances is kept under a maximum power threshold of the power grid; and controls the operation of the appliances based on the time schedule. The at least one control unit is configured to generate the time schedule by exploiting a Particle Swarm Optimization approach.
