The 6th IEEE COMNETSAT 2017 which was held by Polines on 5 – 7 October 2017 presented the session plenary talk on the first day.
The Plenary Talk featured three speakers, namely Prof. Hiroshi Ochi (Japan), Prof. Mahamod Ismail (Malaysia) and Dr. Khoirul Anwar (Indonesia).
Prof. Hiroshi Ochi is a professor at the Department of Computer Science and Electronics, Kyushu Institute of Technology and has published more than 50 journal papers and more than 150 international conference papers. The field that is the subject of research by Prof. Ochi covers digital signal processing, wireless communication, design Large Scale Integration (LSI), and technology management. Along with the increasing use of robots in the industrial world – for example in the vehicle assembly industry – Prof. Ochi stated that the need for the use of wireless networks (wireless) on the control of the robot is getting higher. This is because of the various advantages offered by wireless networks, among others, in terms of ease of installation and maintenance, and can be implemented in locations that are difficult to reach when using a wired network. However, protocol Point Coordination Function (PCF) Conventional WiFi is not capable of supporting Ethernet specifications for industrial purposes, such as low latency (less than 0.1 milliseconds) and requirements for error-free and secure communication for humans. At this conference Prof. Ochi explained about system design Wireless Local Area Network (WLAN) which is fast and secure for application in industry.
Prof. Mahamod Ismail from the Department of Electrical, Electronics and Systems Engineering, Universiti Kebangsaan Malaysia who spoke at the session plenary talk the second has areas of research studies on mobile communications, satellite communications, and wireless networks. Prof. Ismail presented the role and challenges of satellite communications in welcoming the presence of the 5th Generation (5G) wireless system. The 5G system is encouraged not only to increase network capacity, but also to increase battery operational life in mobile devices such as mobile devices smart phone and tablet. The solution offered is to evolve the network development from macro-cell traditional to small-cell suitable for tissue densification that can be developed into Dense Femtocell Network (DFN). The main challenge is to provide backhaul network (main network) that can not only maximize service coverage but also guarantee needs data throughput. Although in densely populated urban areas this need can be served through optical cables, but in rural areas (rural) Microwave and satellite radio communications are still an option. Therefore, satellites need to be developed into components of the 5G system, both as an extension network and even as a network backhaul. Although this integration has started since the 3rd generation (3G) network, optimization and topology reconfiguration has not been carried out according to traffic needs.
At this conference Prof. Ismail explained about the evolution of integration between satellite communications and terrestrial communications; the role of the satellite as a transmission medium and extension of service coverage; scheme channel access and sharing effective; harmonization of capabilities through Very Small Aperture Terminal (VSAT), High Altitude Platform (HAP) and High Throughput Satellite (HTS); as well as options gateway and backhaul on 5G systems.
The third session featured Dr. Khoirul Anwar, who since September 2016 is an Associate Professor at the School of Electrical Engineering at Telkom University, Indonesia with research interests in network information theory, error correction coding, iterative monitoring, encoding for super-dense networks, and signal processing in wireless communications.
At this conference, Dr. Anwar explained the potential of the scheme multiple access on a massive 5G wireless connection which is expected to serve up to 40-50 billion devices connected to the Internet, for example through applications Internet of Things (IoT). Based on mathematical concepts, especially probability theory, binomial and exponential distribution, better IoT access technology can be provided, namely (a) throughput higher so that it can serve more devices or users, (b) rapidly packet loss lower, (c) network optimization, and (d) IoT limitations theoretically provide user or device detection capabilities per time slots. It is expected to be used in the development of IoT networks and applications covering up to 2/3 of the global economy.
After plenary talk, executed 5 parallel session for 2 days with the presentation of 30 scientific papers (paper) who have passed the selection, consisting of 14 field papers communication, 10 field papers networks, and 6 field papers satellite. The authors of the paper came from 6 countries namely Italy (2 papers), Egypt (2), China (2), Philippines (1), Singapore (1) and Indonesia (22).
