TECHNOLOGY INVENTOR OF NEW SATELLITE - BASED MOBILE PHONE

Armed with his expertise in the field of satellite telecommunications, he produced the technology as well as new product that does not exist in the world market. Adi innovation enables communication through mobile phones can be done anywhere. When the cable network has not reached and the conventional cellular phone signal loss, telecommunications system findings remain "on"."During the visible sky overhead, communication through mobile phones can be done", said Adi, Chief Executive Officer & President Director of PT. Pacific Satellite Nusantara (PSN), which also occupy the same position in the Asia Cellular Satellite (ACeS). Telecommunications equipment and efficient free blank spot where this is possible thanks to the idea of ​​installing telecommunications satellites in geostationary orbit. On imaginary track that is located 36,000 km above the earth's surface, Adi puts Garuda 1 satellite. The satellite weighs 4.5 tons of ideas that are equipped with two twin umbrella antennas 12 meters wide and capable of reaching a third world area. Because the size is quite large, the intensity of the signal beam is also quite large.The launch of the world's largest civilian satellite in February 2000 that cash makes shrink the world's satellite phone operator. When it is, arguably, the world's telecommunications satellite was launched in low orbit (600-1000 km) and medium (7000-10000 km). Satellites for coverage is limited. In order to cover one side of the world takes around 60 satellites berorbit low or medium berorbit 12 satellites. Another drawback to the operation of satellite telecommunication systems mobile telephone when it is his plane that is not practical. Mobile phone device that can be used to communicate via satellite rather large size, almost as big as suitcases traveling. To operate it is also necessary earth station, a one meter diameter parabolic antenna.Adi breakthrough that made not only expand the scope of the satellite, also minimize the dimensional plane of this satellite-based mobile phone. With a transmit power 10 kw, Garuda 1 signal can be received by the mobile phone once the plane is the earth station. "This is the smallest and cheapest earth station ever made man", said Adi pointing Ericsson R190 mobile phone. Satellite phone network which berinduk to Garuda 1 was then packaged with a trademark Byru.The workings of this phone is very dependent on the Garuda 1, which controlled the satellite control facility on the island of Batam. It also built a network control center (network control center - NCC), the regulator governing the flow of conversation with the panel. Garuda 1 is able to serve 22,000 conversations at the same time. In addition, also built a gate (gateway) that serves as a local operator. With Byru, customers can contact one another satellite phone, to a GSM phone and to phone home. Each connection request will be done via satellite. The request was analyzed by the NCC Batam, to determine the identity of the caller and determine which gateway is compatible with the call destination. After that, the connection request will be forwarded to the destination phone. The talks were ongoing. All processes were running very quickly, in just seconds.To realize the idea, Adi did not do it alone. Although Garuda 1 was made by Hughes Aircraft (where he once worked), the United States and made R190 Ericsson, Sweden, designs made by Adi and his team at PT Pacific Satellite Nusantara (PSN), which was founded and Adi Iskandar Alisjahbana in 1991. Together with professor and former rector of ITB's, born Byru and must - trademark PSN artificial satellite telephone system. "The strength Adiwoso is entrepreneurship," said Iskandar. Without the courage to market itself, it could be finding geostationary satellite phone so it's just a prototype in the laboratory. Or even become merchandise of foreign companies that can capitalize on these findings.With this PSN telecommunication devices, Byru, must (Post Your Own Phone) and Internet services Bina (Information Center of the archipelago), populations inaccessible areas wired telephone network and other wireless-telephone can still be fun and explore the information via the Internet. At the end of 2003, PSM claims to have freed 2975 villages in 40 districts in Indonesia from the isolation of telecommunications by satellite-based instruments.His ability to develop a satellite telephone business, while its competitors gasping (one of them, even Iridium was bankrupt), more or less inseparable from his experience working in the satellite business. After earning a degree in aeronautical and Astronautical Engineering from Purdue University, United States, Adi worked at Hughes Aircraft Company. There he participated in the process of making an order satellite Palapa Indonesia. After eight years working at the company's satellite maker with her colleague, Adi founded Orion Satellite Asia Pacific in Washington DC. Because of preoccupation with work, his intention to pick up a doctoral program at the California Institute of Technology, failed completely. This aspiration to be an expert aircraft was forgotten.Long in shoreline did not eliminate the longing in his hometown. He rejected an offer green cards, tickets become citizens of the United States and choose to work in their own country. In 1982, he boyongan to Jakarta. But barely eight years working in the country, Adi chose early retirement. Her love of nature in the country made up his mind to wander from Ujung Kulon to Maumere. At one point, Alexander asked his opinion about the plan to sell the Palapa B-1 that have been depleted of its life. Satellite "junk" had estimated a company in the U.S. for U.S. $ 50,000. Get that information, business brain works. "Why are sold. We just run, "said Adi. Is formed PT Pacific Satellite Nusantara (PSN) in 1991. Initial capital, of urunan Adi and Iskandar to buy the Palapa B-1. Then point the satellite's orbit is shifted to the east, so as to include small islands in the Pacific. His name turned into a Pacific satellite. Adi began to drive this business. Up to evolve, from "mere" operate and lease the Pacific 1, PSN and then stepped to a larger scope. Together with his team on the PSN, its expertise in satellite business more intensively explored again with ACeS founded in 1994. There, PSN holds 35% stake and took Lockheed Martin, Global Philippines Long Distance Telecommunications (PLDT) and Jasmine International (Thailand) as a partner.To realize the ambition of creating a satellite-based telecommunications system with the GSM (global system for mobile communication), ACeS also entered into the Nasdaq Stock Exchange, New York. With a capital of U.S. $ 750 million, meluncurlah Garuda 1 into space. Not long ago, Byru also slid to the market. The success of Garuda 1 made a name adopted from flying. In the country, developing products PSN service. In addition to playing in the satellite communications business, PSN also entered into a multimedia business with the launch Multi Media Asia. Everything is based satellites. (A. Strong Karsadi)
