8. Satellite CommunicationsLow cost satellite-based access to the Internet could respond to the current access crisis <strong>in</strong>the region <strong>and</strong> provides an opportunity for last mile connectivity to rural people. The vast<strong>in</strong>accessible terra<strong>in</strong> makes it difficult <strong>and</strong> costly for roll<strong>in</strong>g out traditional wirel<strong>in</strong>e networks<strong>and</strong> implement<strong>in</strong>g advanced fiber optics l<strong>in</strong>ks <strong>in</strong> heartl<strong>and</strong> areas. The lengthy time neededto rollout traditional technologies makes low-cost Ku/Ka b<strong>and</strong> satellite services attractiveparticularly to smaller organization, households, personal users, small <strong>and</strong> mediumenterprises <strong>and</strong> public organizations.Access to VSATs is prohibited <strong>in</strong> some countries. In other nations hefty licens<strong>in</strong>g fees arelevied. Policies for low-cost 'consumer grade' satellite services for Internet access are notclear <strong>in</strong> many nations. Recent surge <strong>in</strong> the use of Voice over IP by average consumers <strong>and</strong>cont<strong>in</strong>ued fall<strong>in</strong>g of PT&T revenue streams have complicated the matter. Governmentpolicies did not keep up with technological developments, <strong>and</strong> most countries are stillprotect<strong>in</strong>g their monopoly national telecom operator at the expense of affordable <strong>and</strong>universally accessible services. Much of the restrictive policy owes to general lack ofunderst<strong>and</strong><strong>in</strong>g of the technology <strong>and</strong> its impact on the society.In countries where private satellite services are allowed, the license fees are usuallyexcessive for consumer-grade Ku-b<strong>and</strong> VSAT when compared to what consumers <strong>in</strong> thedeveloped countries pay for these services. The tariffs were ideal for the older satellitetechnologies which were far more expensive to operate, largely conf<strong>in</strong><strong>in</strong>g their use to a fewlarge mult<strong>in</strong>ational companies. At the moment, lofty license fees are the major obstacles toInternet development <strong>in</strong> Africa, where up to 35% of ISP expenditures goes to VSAT license<strong>and</strong> monthly charges. Licens<strong>in</strong>g fees <strong>in</strong> Africa range between $5000 <strong>and</strong> $10,000 dollars ayear per term<strong>in</strong>al on an average for a 128 Kbps l<strong>in</strong>k. Although is a significant progress <strong>in</strong>reduc<strong>in</strong>g both licens<strong>in</strong>g <strong>and</strong> monthly fees, there are high potentials for mass deployment ofequipment cost<strong>in</strong>g $1000 <strong>and</strong> Internet b<strong>and</strong>width at $200/month or less.Technically, every <strong>in</strong>ch of Africa is covered by VSATs. The major operators like New Skies,Intelsat, PanamSat, EuropeStar, Eutelsat, Thaikom <strong>and</strong> Anatolia/KaliTel have a variety ofdifferent footpr<strong>in</strong>ts over parts of Africa to supply voice, broadcast<strong>in</strong>g <strong>and</strong> data circuits to avariety of customers, who then could resell to end users, create Virtual Private Networks.Recent launch of satellites by Intelsat, Panamsat <strong>and</strong> New Skies has also extended theamount of available b<strong>and</strong>width for sub-Saharan Africa.Significant experience <strong>and</strong> <strong>in</strong>terest has also been ga<strong>in</strong>ed <strong>in</strong> the <strong>in</strong>stallation, ma<strong>in</strong>tenance<strong>and</strong> subscription services over the last ten years. Among the companies that are currentlyprovid<strong>in</strong>g services are, Afsat (headquartered <strong>in</strong> Kenya), MenaSat/GDBC (based <strong>in</strong> Egypt),IVSAfrica (based <strong>in</strong> Spa<strong>in</strong>), Web Sat (a branch of Dubl<strong>in</strong> Irel<strong>and</strong> based ArmstrongElectronics), Thaicom Internet (part of the Thai group Thaicom), Bentley-Walker (UK),47
