A method of assigning radio frequencies to base stations (-) of a first radio telecommunications network operating in a first radio frequency band and co-existing with at least a second radio telecommunications network (--) 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 (-) of the first radio telecommunications network frequencies in accordance with the radio frequency assignment plan selected.

Method of planning of mobile telecommunications networks

The radiation diagram of an antenna for serving a cell in a cellular communication network is selected from a plurality of available radiation diagrams by: classifying the plurality of available radiation diagrams in terms of a related radiation gain value; identifying for each one of the sectors a plurality of variations of the radiation gain value associated with the available radiation diagrams; estimating for each sector an initial value of at least one indicator of network operative functionality; estimating for each sector at least a desiderate value of variation of the related radiation gain value; and selecting at least one configuration that approximates the variation of the radiation gain value involving the desiderate value.

Method and system for selecting radiation diagrams of antennas for mobile-radio communication networks

A method for selecting a subset of sites within a set of candidate sites for activating one or more radio stations of a telecommunications network includes building an initial solution of a subset of sites starting from a network configuration having the whole set of active candidate sites; and optimizing the initial solution for activating 'inactive' sites and/or deactivating 'active' sites, in order to minimize a predetermined cost function for the solution. The steps of building and optimizing the initial solution are adapted to define both solutions that have a geographic coverage area that is greater than a predefined minimum coverage area and to manage an amount of traffic that is greater than a predefined minimum expected traffic value. A processing system and a processing program or group of programs can be executed by the system when pre-arranged for performing the above method.
