      –   End of the protection of analogue reception
             •   GE-06 Agreement (2015 for UHF and June 2020 for VHF in Africa, GE-06 Article 12)

•   The development of broadband mobile requires more spectrum
      –   Avoid digital divide, especially in rural areas
      –   Bring high data rate to each citizens

•   The switch-off of analogue TV allows for introducing new services and
    applications, and offers opportunities to introduce broadband band mobile on a
    large scale for Region 1

          862 MHz Band
      –   LTE standard is in time with the analogue switch-off

                 Obligations about TV protection
• Operators that will operate 790-862 MHz Band should take into
  account the protection of TV against interferences created by their
  networks (inserted in the authorisations)
• Imposed by the Finance law (tax)
• In a limit of 2 million Euros per year, all costs incurred by the ANFR
  for the collection and processing of claims viewers related to
  interference from stations in this frequency band.
• Once determined the amount of the contribution charged to the
  assigned frequencies, this amount will be divided among them
  according to the interference that may be caused by the use of blocks
  frequencies allocated to them. This allocation rule (below) should
  allow to take into account the greater or lesser likelihood of mobile
  operators in participating in interference by frequency block assigned.
  In addition, this allocation rule will not take into account the dates set
  actual service of the various radio stations.

                Possibles solutions for protection
                                  of TV reception

• Inserting filters of LTE signal in the reception chain of the DVB-T
• Co-sitting LTE BTS and DVB-T transmitters or gap-filler transmitters
• Modification of the direction of the receiving antenna
• Use a antenna more directive
• Modification of the high of the BTS LTE antenna
• Atenuation of the DVB-T received signal
• Removal of amplifier devices in the DVB-T reception chain where not
• Decrease the e.r.p of the LTE BTS
• Use an other type of TV reception (ADSL, satellite)
