  2. Presentation outlines 1-Market envirenment 2-Old Analog technologies used for rural wireless connectivity 3-Digital technologies used for rural wireless connectivity 4-conclusion

  3. 1-Market envirenment • Telecommunications is a key enabler of economic and social development of a nation • Universal service is a particularly urgent issue for rural and remote communities • Today Internet access becomes as essential as telephony • New multimedia services and technological convergence are shifting the regulatory focus to UNIVERSAL ACCESS

  4. - 1-Market envirenment (Cd) • Regulators are focusing on universal access • Specific conditions are elaborated for rural areas coverage on fixed network licences • Operatores are looking for economic and effecient solutions to provide universal service for rural and remote communities -

  5. 2 - ANALOG WIRELESS TECHNOLOGIES USED FOR RURAL CONNECTIVITY- -

  6. 2.1 Mono-channel & Bi-channel systemPrincipe : use a radio link to connect remote subscriber moddule to the subscriber equipement into the swichFrequency : UHF / VHF Range : UP to 40 km -

  7. 2.1 Mono-channel & Bi-channel system (Cd)Applications : - isolated subscribers - rural public phone - farm - police - custom control pointService : basic telophony -

  8. 2.1 Mono-channel & Bi-channel system (Cd) UHF/VHF Interface analogique (2 fils) Station d'abonné (une ou 2 lignes) Central téléphonique

  9. 2-2 : Fixed Analog Cellular System Priciple : use the analog cellular network to provide fixed telephony service Applcations : connect isolated subscribers located on the coverage area of the analog cellular Network Frequency : 450 MHZ , 900 MHZ Range : UP to 30km

  10. Station de base Terminal d’abonné radio Commutateur du réseau mobile RTC 2-2 : Fixed Analog Cellular System (Cd) Service fixe Service mobile

  11. Common Standards used for Analog Cellular System 2-2 : Fixed Analog Cellular System (Cd)

  12. Others Standards used for Analog Cellular System 2-2 : Fixed Analog Cellular System (Cd) • N-AMPS (Narrow Advanced Mobile Phone) • TACS (Total Access cellular System) • E-TACS (Extended Total Access Cellular • J-TACS (Japan Total Access Systeù

  13. 3 - DIGITAL WIRELESS TECHNOLOGIES USED FOR RURAL CONNECTIVITY -

  14. 3-1 : Point to Multipoint Radio System Principe : Radio acces Network point to multipoint using wired and/or wireless termination • Frquency : 1.4 Ghz - 2.7 Ghz • TDM technologies • Range : 10 to 200 km

  15. Station d'abonné Station d'abonné Station d'abonné Station centrale 3-1 : Point to Multipoint Radio System (Cd) Téléphone Interface Analogique/numérique FH (1,5 –> 2,7 GHz) Donnéesbas débits Téléphone Donnéesbas débits RTPC Station Relais Téléphone Donnéesbas débits Système de gestion de réseau

  16. 3-1 : Point to Multipoint Radio System (Cd) Applications : Connectivity of small villages Services : Telephony Data (narrow band) Management of Priority for some subscribers Emmergency call Capacity - Base station : 500 subscribers - Terminal station : micro station : 2-4 sub large station : 128 sub

  17. 3-2 -Wireless local loop : WLL Principle : using digital radio-acces to provide fixed telophony service Applications : connectivity of rural and suburban areas Services : Telephony : All PSTN services Data : 64 kb/s and more

  18. 3-2 -Wireless local loop : WLL (Cd) Interface radio Téléphonie Station centrale Système de gestion Réseau de transport FH, FO ou cuivre (xDSL) Terminal d’abonné radio BS BSC V5.2 ou Analogique Contrôleur de station de base + Station de base données PSTN Zone Suburbaine/Rurale

  19. 3-2 -Wireless local loop : WLL (Cd) Common Standards used for WLL

  20. 3-2 -Wireless local loop : WLL (Cd) Common Standards used for WLL (Cd)

  21. 3-3 : Fixed and /or Restricted GSM - Principle : Using GSM Networks to provide fixed telephony ( or restricted mobility ) • Applications : Connectivity of rural areas • Services : telephony : all GSM services Data : - circuit : 9.6 kbps : - GPRS : 30-52 kbps

  22. 3-3 : Fixed and/or Restricted GSM (Cd) Frequency : 900 Mhz , 1800 Mhz , 1900 Mhz Range : up to 35 km

  23. MSC BTS Fixed GSM Terminal BTS BSC 3-3 : Fixed GSM (Cd)

  24. MSC BTS All other cells are barred for that Subscriber BTS Allowedmobility for that Subscriber BSC 1 3-3 : Restricted GSM (Cd)

  25. Limited mobility option and rich set of value-added services when using mobile handsets Smooth migrationto GPRS/EDGE enabling higher data rates and new services

  26. Proven, very mature technology Large range - up to 35 km in an open rural environment High spectrum efficiency for voice services Excellent & stable coverage/capacity ratio Advantages of GSM for limited mobility solutions 3-3 : Fixed and/or Restricted GSM (Cd)

  27. Smooth migrationto GPRS/EDGE enabling higher data rates and new services • Limited mobility option and rich set of value-added services when using mobile handsets

  28. For rural and suburban areas, wireless solutions are less costly than wired when subscribers are spread • Quick deployment and easy installation • The fixed GSM solution is capable of evolving to a full mobile solution • Pre-paid (public phones & mobile pre-paid) for all users through the same IN platform

  29. 3-4 Rural connectivity using V.SAT System Principle : provide fixed telophony & Data services using satellite links Applications : connectivity of wide rural areas with very low density Services : Telephony : All PSTN services Data : Circuit switching n*64 kb/s : Packed switching : Ethernet
