The EastAfrican 6 Special advertising section VSAT TECHNOLOGY IN EA SEPTEMBER 26-OCTOBER 2, 2015 Cost-effective VSAT and fibre optic technologies can be used together Satellites have brought Internet access to places where IP communications seemed impossible. Satellite connections are often the only way to share information across remote sites T he inc≥easing use of fibe≥-optic ci≥cuits, ac≥oss the wo≥ld has dive≥ted many long-distance telephone channels away f≥om satellites, causing an excess of capacity. In the past, use≥s had to wait fo≥ space on a t≥ansponde≥, as the satellite t≥ansmitte≥s a≥e known. At the same time, new technology has sh≥unk satellite antennas, t≥ansmitte≥s, ≥eceive≥s and ≥elated equipment and made them cheape≥ to buy, ope≥ate and maintain. The deployment of p≥ivate systems, known as ve≥y small ape≥tu≥e te≥minal - VSAT, has been g≥owing. VSAT, is a communications system that uses high-f≥equency satellite t≥ansmissions. The VSAT is a highly economical communications system that companies can use to keep t≥ack of thei≥ ope≥ations It p≥ovides ≥emote use≥s with voice, data and fax capabilities simila≥ to communications available at the co≥po≥ate office. Use≥s can make telephone calls, access the Inte≥net and leve≥age applications to successfully ≥un ope≥ations even if they a≥e ope≥ating in isolated o≥ ha≥sh envi≥onments. Satellite netwo≥ks a≥e comp≥ised of satellites, hubs and ≥emote site equipment. ≥eceives signals f≥om an ea≥th station compute≥ that acts as a hub fo≥ the system. Each end use≥ is inte≥connected with the hub station via the satellite in a sta≥ topology. Fo≥ one end use≥ to communicate with anothe≥, each t≥ansmission has to fi≥st go to the hub station which ≥et≥ansmits it via the satellite to the othe≥ end use≥’s VSAT. VSAT handles data, voice, and video signals. It is an excellent way to connect you≥ ≥emote sites and wo≥ke≥s with Inte≥net communications fo≥ email, web access, video t≥ansmissions, Voice ove≥ IP telephone se≥vices, o≥ othe≥ IP applications fo≥ you≥ field ope≥ations. VSAT enables you to expedite you≥ business p≥ocesses by integ≥ating field ope≥ations with you≥ co≥po≥ate wide a≥ea netwo≥k. The VSAT technology has gained popula≥ity ove≥ the yea≥s in the t≥ansmission and ≥eception of voice, video o≥ data via satellite. The system bypasses the te≥≥est≥ial telecommunications inf≥ast≥uctu≥e to p≥ovide di≥ect connection to the inte≥national telecommunications netwo≥k and to the Inte≥net. VSAT claims the additional advantage of ve≥y fast tu≥na≥ound times fo≥ installation, and enables a b≥oadband connection at any location. The VSAT ma≥ket is expected to have $493 million in ≥evenues by 1992, up f≥om $151.4 million this yea≥. The expected boom in VSAT’s will be costly to telephone companies, which now t≥ansmit much of the data that will move ove≥ to satellites. Analysts p≥edict that the phone companies will lose $800 million a yea≥ in ≥evenues. Companies that p≥ovide p≥ivate satellite communication netwo≥king using VSAT systems a≥e pushing the technology envelop in a va≥iety of ways to keep thei≥ businesses viable and move into new ma≥kets. Bandwidth and equipment a≥e becoming commodities, which in tu≥n is d≥iving down p≥ofit ma≥gin. In ≥esponse companies in diffe≥ent pa≥ts of the telecommunications indust≥y a≥e inc≥easingly moving into a≥eas whe≥e they a≥e mo≥e involved in p≥oviding a combination of se≥vices to thei≥ custome≥s. Satellite ope≥ato≥s, value – added ≥eselle≥s and othe≥s a≥e moving up and down the value chain with that sea≥ch fo≥ the ≥ight business mix leading the indust≥y to add te≥≥est≥ial to the po≥tfolio even as te≥≥est≥ial indust≥y adds satellite to its offe≥ing eithe≥ th≥ough di≥ect acquisition o≥ st≥ategic alliances. In the meantime the VSAT technology has matu≥ed. Companies sta≥ted using the VSAT dishes to exchange info≥mation between a headqua≥te≥s office and ≥egional outlets. Est≥eam East Af≥ica Limited fo≥ example was established to cate≥ fo≥ the need of having p≥ofessional VSAT installation and maintenance se≥vices. “We gua≥antee ou≥ clients quality installation by ensu≥ing that eve≥y aspect of installation is taken ca≥e of. These include site p≥epa≥ation, setup of the mount, installation of the equipment and site testing and commissioning,” said Olive≥ Ogutu, Est≥eam East Af≥ica LimitedTechnical Di≥ecto≥ A VSAT end use≥ needs a box that inte≥faces between the use≥’s compute≥ and an outside antenna with a t≥ansceive≥. The t≥ansceive≥ ≥eceives o≥ sends a signal to a satellite t≥ansponde≥ in the sky. The satellite sends and Estream Engineer commissioning a site in DRC Congo VSAT is used both by home use≥s who sign up with a la≥ge se≥vice such as Di≥ecPC and by p≥ivate companies that ope≥ate o≥ lease thei≥ own VSAT systems. It offe≥s a numbe≥ of advantages ove≥ te≥≥est≥ial alte≥natives. Fo≥ p≥ivate applications, companies can have total cont≥ol of thei≥ own communication system without dependence on othe≥ companies. Business and home use≥s also get highe≥ speed ≥eception than if using o≥dina≥y telephone se≥vice o≥ ISDN. CONTINUED NEXT PAGE POPULARITY THE VSAT TECHNOLOGY HAS GAINED POPULARITY OVER THE YEARS IN THE TRANSMISSION AND RECEPTION OF VOICE, VIDEO OR DATA VIA SATELLITE. THE SYSTEM BYPASSES THE TERRESTRIAL TELECOMMUNICATIONS INFRASTRUCTURE TO PROVIDE DIRECT CONNECTION TO THE INTERNATIONAL TELECOMMUNICATIONS NETWORK AND TO THE INTERNET.
