After the completion of the DTT migration process for the release of the 700 MHz band that is part of the 5G auction, on December 14 last year, Anacom started a series of monitoring actions with the objective of carrying out a technical verification of the range in question throughout the national territory.

In a statement, the entity explains that the action started in Alto Minho and Trás-os-Montes, in the districts of de Bragança, Vila Real, Braga and Viana do Castelo: a geographical area that represents 15% of the national territory and covers 12% of the population.

Due to the orography and proximity to Spain, the areas under study are more difficult to cover. Thus, the spectral analysis gains greater importance, ensuring the absence of any harmful interferences to the implementation of 5G in these locations and range.

According to Anacom, during the first phase, monitoring was carried out in about two hundred locations, covering more than 2,600 km and covering district capitals, county seats as well as more isolated areas of the country, “in order to ensure that the 694/790 MHz (700MHz) band is fully operational for use by operators competing for the 5G auction, regardless of the geographical area concerned ”.

The figure represents the spectral visualization of the 700 MHz band without interference signals. It is possible to observe the signal levels (vertical axis) as well as the frequency range of analysis (horizontal axis); the green color indicates the instantaneous spectral values ​​and the red the maximized values ​​in a determined time interval.

The band monitoring initiative to be allocated to fifth generation networks will continue in the coming weeks and months in the rest of the territory and in the autonomous regions of the Azores and Madeira, as well as through the use of the 18 control stations of the national spectrum monitoring system ( SINCRER – National System for Remote Control of Radio Stations).
