MOBILE COMMUNICATIONS
Short-term trend is to extend VHF coverage by deploying remote VHF stations (Algeria, Egypt, ASECNA, etc.).
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
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
