3.2 The primary network of the new digital network should be the satellite network, in view
of the high availability of a satellite-based network, as shown by the existing digital network in the SAM
Region (REDDIG) in the last ten years.
3.3 The ground network should encompass all the States of the Region. According to the
information presented by the communication service providers, there were some States in the Region
where the provider had no operations and therefore the regional communication service provider had to
coordinate with other communication service providers in order to provide coverage to those countries,
thus possibly increasing the cost of services in such locations.
3.4 Since SAM States had approved the mixed (satellite + ground) network solution for the
new digital network in the SAM Region, the technical specifications would be prepared taking into
account the adopted solution. The implementation of a network would depend on the cost involved in
this solution. The decision would be made at the Twelfth Meeting of Civil Aviation Authorities of the
South American Region (RAAC/12) (Lima, Peru, 3-6 October 2011).
3.5 The technical specifications to be drafted should not take into account the technical
requirements of the new network but rather the performance parameters, such as availability, safety,
integrity, reliability, robustness, management capacity, and life of network equipment.
3.6 Furthermore, to ensure network availability, the technical specifications should include
the necessary spare parts and training for the personnel that will be responsible for maintaining the new
network.
3.7 Consideration was given to the possibility of reusing some pieces of equipment of the
existing network, such as the amplifiers and the antennas. In this sense, the companies participating in the
bidding process should make site visits to confirm such possibility.
3.8 Likewise, it was also felt that the technical specifications should include the requirement
for installing the new network in a way that ensured service continuity. One such requirement would be
the need to have additional bandwidth.
