Quick reminder –African Demographics
1.1 billion people
over 50% under the age of 25
60% rural
National Development –who is it for?
Urbanites living in Major CitiesVillage Dwellers living in rural areas
Or Both?- Universal Service Directive: “The European Union intends to ensure the availability of a minimum set of high-quality services that are available to all users at an affordable price, without distortion of competition.”
Obvious Answer is BOTH!- Real Question then is HOW?
Satellite is the “natural” answer!
Coverage spans the whole continent (1/3 of the world in case of GEO)
Reaches almost everywhere
Quick deployment High service availability as
compared to currently available terrestrial alternatives
Satellite service “challenges” (historical perspective)
Low level of competition in Africa – basically single source
High prices of space segment; inflexible terms
Usage limited to high – end customers in mining, finance and some government (UN, National) and National Broadcasters
Fast forward 10 years to 2015
New satellites launched by Intelsat covering the continent in both C and Ku bands
New pan-African or regional coverage by systems such as ArabSat, Eutelsat, Gazprom (Yamal), NileSat, SES (Astra, NewSkies), Spacecom (AMOS) in addition to Intelsat again in both Ku and C band
Emerging Ka band services MEO satellite system by O3b providing new opportunities
Taking advantage of the new Opportunities
“Problems” becoming “Challenges” now “Opportunities”
Content delivered by broadcasting (single data stream received by all remotes)
Shared locally between similar user groups, providing “last-mile” connection using terrestrial options
WiMAX TV WhiteSpace LTE ISM other unlicensed bands
IP and “Unified Communications” for voice, video, chat, image, data, etc., etc.
Satellite technology based on IP becoming
LAN in the Sky
Layer II switching, not Layer III routing
Fast data flow with little buffering
Cheap remote VSATs antennas 1.2 meter or below (Ku band)
Ka band coming up
This is what to avoid…
Each and every user / department / school has their own VSAT
