A method for estimating an occupancy level of a geographic area includes transmitting first signals to and receiving second signals from bodies within the geographic area by backscattering of the first signals. The bodies include first bodies permanently within the geographic area and second bodies temporarily within the geographic area. According to the first and second signals, a first map of the first bodies within the geographic area is generated. At a specified time period, following a reference time period, transmission of the first signals, reception of the radio signals and generation of the first map is repeated. According to the first and second signals, a second map of the bodies within the geographic area is generated. A number of the second bodies within the geographic area during the specified time period is determined as the occupancy level based on comparing the first map to the second map.

Method and system for estimating an occupancy level of a geographic area

A method of planning deployment of a radio communication network in at least a portion of a geographic area is provided. The method comprises: providing a three-dimensional model of the at least a portion of the geographic area; providing a model of at least one radio base station, the model comprising at least an indication of a position of the radio base station within the geographic area; and evaluating a propagation channel within the at least a portion of the geographic area associated with electromagnetic radiation, radiated by the at least one radio base station, at predetermined positions in the three-dimensional model of the geographic area. The method further comprises planning the deployment of the radio communication network based on the evaluation of the propagation channel.

Method and system for radio communication network planning

A method predicting coverage area of a radiocommunications network including plural network cells distributed over a geographic area. The method includes calculating by simulation an irradiated electromagnetic field irradiated by a radio base station of the network in plural measure locations within the geographic area corresponding to respective expected positions of a user terminal. The calculating includes, for each measure location, calculating a basic transmission curve indicative of a basic attenuation of a radioelectric signal strength in the measure location, and associating to the basic transmission curve at least one correction factor for refining the radioelectric signal strength basic attenuation by taking account of shielding effects on the radioelectric signal strength due to obstacles to the propagation of the radioelectric signal.

Method for the prediction of coverage areas of a cellular network

Downlink and uplink communication resources to ensure network coverage and satisfy assigned traffic requirements in a communication network are allocated by setting a given balance of downlink and uplink communication resources while leaving a part of downlink and uplink communication resources remaining to be allocated. Downlink cell radius and uplink cell radius values are then determined which ensure network coverage with the resources as previously allocated. An effective cell radius is then selected as the smaller of the downlink and uplink cell radius and then a first check is made as to whether the effective cell radius selected satisfies the assigned traffic requirements. If not, the effective cell radius is updated. If so, a further check may be made as whether the resources remaining to be allocated for downlink and uplink have a difference in excess of a given amount. If yes, the procedure is repeated by setting an updated balance of downlink and uplink communication resources reducing that difference. If not, the communication resources are allocated on the basis of the current balance.

Method of dimensioning radio access networks, corresponding system and computer program product

A method for planning a radiocommunications network includes computing cell coverage in turn including dividing a region around a radio base station into a number of large environment pixels, dividing each large environment pixel into a number of small environment pixels, and, for each target small environment pixel, computing a second quantity indicative of the coverage within the target small environment pixel, wherein each second quantity is computed for the respective target small environment pixel as a function of a mixed environment profile describing the environment between the radio base station and the target small environment pixel along a propagation path of a radioelectric signal radiating out from the radio base station and passing through the target small environment pixel, wherein the mixed environment profile describes the environment within small environment pixels close to the radio base station and the target small environment pixel, and within large environment pixels along the remaining stretch of the radioelectric signal propagation path.
