MOBILE COMMUNICATIONS
EVOLUTION OF VOICE SERVICES
Short-term trend is to extend VHF
coverage by deploying remote VHF stations
(Algeria, Egypt, ASECNA, etc.).
Numbers of VHF remote stations declared
by countries in the questionnaires
Countries/
Organisations
Algeria
HF is still maintained in some areas,
though it offers poor quality communications,
as it is considered:
 better than nothing outside VHF coverage
areas,
 cheap back-up to VHF in VHF coverage
areas.
Provisions should however been
considered for Satcom Voice services for
non-routine COM in medium to long-term

REVENUES FROM COCKPIT (MOBILE)
COMMUNICATIONS
DEFINITION OF HIGH REVENUES AREAS AND ROUTE SEGMENTS
Page 11
Satellite-based ATS datalink services in AFI :
 should be mainly used along routes segments
 with medium/high traffic
 and located in oceanic areas or in remote areas, where there are no or limited radar /
VHF coverage
 should include CPDLC and FIS services, plus ADS-C services where no
radar/ADS-B deployment has been implemented or is planned
Satellite-based ATS datalink services in MID:
 should be deployed and used all over Egypt and the Arabic peninsula,
 should include only FIS and CPDLC services as the Radar coverage will be
almost complete in this area
Satellite-based AOC services in AFI/MID:
 are assumed to be used mainly over the routes segments and areas where
Satellite-based ATSC services are provided and used
