All rights reserved © 2005, Alcatel Alenia SpaceSeptember 2005 - M054E-5 backnext Page 8 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 Countries/ Organisations Number of VHF remote stations Algeria16 (+7 in 2006) ASECNA26 Egypt12 Ethiopia5 (planned) Iraq8 Kenya3 Mozambique6 Oman6 Saudi Arabia67 (+4 planned) Sudan8 (planned) Syria8 Tanzania5 Yemen3 Numbers of VHF remote stations declared by countries in the questionnaires EVOLUTION OF VOICE SERVICES
