HELP LTE/DVB-T interferences

Management of LTE 800 MHZ Band interferences on Digital Terrestrial TV signal reception

HELP Interferences is a service supporting citizens suffering interferences in the reception of digital terrestrial TV signal caused by LTE mobile telephony systems.

Goals

The HELP Interferences service supports citizens experiencing a bad reception of digital TV signals, helping them in verifying if they are caused by LTE interferences, and helping them in solving their problems.

Impact

Help Interferences is the institutional assistance service that:

  • Receives the claims form citizens related to a bad digital TV signal reception, by means of a telephone call to a green number (800 126 126) or filling out a digital module at the www.helpinterferenze.it web site.
  • Verifies the actual impact of the LTE emission on the DTV signal.
  • Activates a free of charge intervention on the citizen reception antenna.

The management and the execution of the Help Interferences service is achieved by Fondazione Ugo Bordoni, an independent third body acting under the supervision of the Italian Ministry of Economic Development.

Description

Help Interferences is the assistance service that supports citizens experiencing interferences among LTE and DTV signals. LTE technology is the base for the 4th generation mobile telephony services (4G) allowing a super fast Internet connection for smartphones and tablets. The Italian Ministry of Economic Development has established a Technical Table to allow a proper development of the 4G LET service, using 800MHz band, taking into account eventual LTE-DVB-T interferences, with the participation of FUB and Mobile Telephony Operators that bought the right to operate in the 800 MHz band.

The Technical Table activities dealt with study of problems related to radio interferences, definition of the impact of bad reception of the TV signal at the users’ side, definition of the actions and procedures required to solve the interferences problems.

During the year 2013 the Italian Ministry of Economic Development released the Regulation including the measures and the interventions procedures that Mobile Operators have to apply to minimize the interferences between wide band mobile services and digital terrestrial TV reception at home, in conformance to the “Decreto Ministeriale 9 agosto 2013, n.165” published on the Gazzetta Ufficiale della Repubblica Italiana n. 44 – 22 febbraio 2014.

The Regulation establishes the Mobile Operators assign to FUB, independent third body acting under the supervision of the Italian Ministry of Economic Development, the role of “Manager” of the LTE interferences mitigation service and that the Ministry avails of the technical, scientific, operational, logistic and communication support of FUB to identify and to evaluate the more proper techniques of the interferences mitigations according to the available national and international standards, methods and best practices.

The FUB management activities of the Help Interferences assistance service are defined in two distinct agreement documents, separately agreed with Mobile Operators and Ministry.

FUB, as Manager, also takes care of carrying out communication campaigns towards citizens to inform them about how to use the Help Interference service, also using social networks and email campaigns towards the municipal administrations of the areas affected by LTE interference phenomena.
