NOTES FOR WEBSITE NAVIGATION

This website provides a focus of TIM's broadband and ultra-broadband fixed network infrastructure, representing region by region through a provincial level aggregation. With the same method, the site provides also the territory coverage with mobile ultra-broadband network (4G and 4G plus technology), in terms of the percentage of municipalities covered. For each province, there is a cartographic part, consisting of a "map" showing the exchanges and connections that form TIM fixed broadband and ultra-broadband network, as well as the municipalities "covered" by the 4G and 4G plus network. , and a second part containing the quantitative data relating to what is shown in the maps.

The description and the cartographic representation of TIM's broadband and ultra-broadband network at the provincial level only concerns the exchanges and the connections between them: it is not possible to provide an accurate representation of the access network, which is the most widespread part of the network that connects the last exchange to a building, the so-called "local loop".

The information contained in this website refers to the situation of the network updated in June 2018, while the provincial maps are updated in December 2017. The data contained in the document refer to the infrastructures managed by TIM.

FIXED BROADBAND NETWORK

The number of active broadband lines was detailed using the same criteria adopted by AGCOM; the amounts could therefore be different from those described in the official reports of TIM, that are processed using a different accounting criteria.
The average monthly data traffic volume (both total and disaggregated) for 2015, 2016 and 2017 are referred to the month of December; data relating to total data traffic on a fixed broadband network represents the traffic carried by the OPM network and measured on DSLAM and OLT.
With regard to the number of exchanges and equipment of fixed broadband network, the term "site" refers to installations of outdoor equipment that do not have all the performs of a traditional exchange, even though they can provide broadband connection service.
The ADSL coverage refers to the percentage of population located in an area served by an exchange with broadband service equipment (DSLAM).

FIXED ULTRA-BROADBAND NETWORK

The percentage of exchanges providing ultra-broadband services has been compared to the total of the exchanges that offer broadband service, excluding the installations of external equipment ("sites") that cannot be equipped with OLT (Optical Line Terminal) ) to provide ultra-broadband service.
The NGAN coverage refers to the percentage of households in an area served by an exchange equipped with ultra-broadband service (OLT).

MOBILE ULTRA-BROADBAND NETWORK

the municipalities covered with 4G technology also includes those covered with 4G plus technology. Any negative changes in yoy refer to repositioning of some mobile network infrastructures which could lead to temporary decreases in terms of coverage;

SARDEGNA REGION

The Regional Law n.2 of 4 February 2016 on the reorganization of Sardegna provinces erased the provinces of Cagliari, Carbonia-Iglesias, Medio Campidano, Olbia-Tempio and Ogliastra, establishing metropolitan area of Cagliari and province of Sud Sardegna; in order to give uniform comparison, all data collected in 2015 and 2016 have been adapted to the current territorial configuration of the region.

CONNECTIONS SHOWN IN PROVINCE MAPS 

Within the maps showing the fixed transmission network in the Italian provinces, there could be some fiber or radio link connection that do not end in any indicated exchange: these are connections terminating in transmission equipment not graphically represented in the maps (i.e. minor sites or mobile base stations);
