ITS-Japan Develop Satellite Internet

Institute of Technology (ITS) Surabaya, along with three Japanese universities to develop a new generation of satellites called the Winds (Wideband InterNetworking engineering test and Demonstration Satellite) which allows maximum speed internet connection.

"Winds in Japanese is called Kizuna that we developed together with JAXA (Japanese space agencies) and the National Institute of Information and Communications Technology (NICT)," said Head of Telematics Laboratory, Department of Electrical Engineering ITS, Moch Hariadi, M.Sc., Ph.D., at Surabaya.

Winds currently using the latest technology that uses a Ka-Band (a system that works at high frequency) having a short wavelength.

"With this specification, Winds are able to provide high-speed Internet connections that reach the maximum 155 Mbps for receiving and 6 Mbps for shipment by the receiving antenna size of 45 cm (equal to the size now), but far beyond the speed that can be achieved today," he said.

Even for a 5-meter antenna size, speed can be achieved are 1.2 Gbps. In addition to high-speed coverage (coverage), the satellite also reaching areas not accessible by a network cable (teresteria). 

"If we compare with the speed of existing internet for personal consumption in Indonesia is only around 384 Kbps and 2 Mbps only, then later we can surf the Internet comfortably," he said. 

In addition, this satellite also allows playback of movies like in a cinema or to the development of simulation research that require high computing in fields such as medical, machinery, chemicals, education, health, handling of the disaster area, and Intelligent Transport Systems (ITS). 

"Today, the Winds are still in the test phase of work on the Ka-band and it is the first experiment in the world to use Band," he said. 

Therefore, he said, ITS fortunate given the opportunity to test. The opportunity was not independent of the cooperation research program in the scheme of JICA PREDICT-ITS. 

"The cooperation that took place during this research conducted by ITS Telematics Laboratory of the three laboratories from three different universities in Japan," he said. 

The three university laboratories in Japan is the laboratory of Prof. Tyusoshi Usagawa (Kumamoto University), Prof. Asc Laboratory Tohru Kondo (Hiroshima University), and the Laboratory of Prof. Takafumi Aoki (Tohoku University). 

In addition to testing technique that involves technical aspects of data transmission via satellite, also made a TV conference application testing and application of PACS (Picture Archiving and Communication System). 

"Currently, we have the opportunity to try the Winds by using fixed earth stations (static) placed in the ITB. Station is not placed in ITS because the type of coverage Winds MBA (Multi Beam Antennas) has not reached the eastern part of Java, but the team plans Winds ITS Winds tested using a mobile earth station (mobile) with type Apaa (Active Phase Array Antenna), "he said.
