Department of Science and Technology's Advanced Science and Technology Institute (DOST-ASTI) organizes a talk about Software Defined Radio and 5G Research last August 1, 2017 at the University of the Philippines-Diliman Electrical and Electronics Engineering Institute (UP-EEEI) MERALCO Innovation Hall.

The guest speaker of the technical overview, Dr. Ian C. Wong, tackled the importance of advanced researches related to fifth-generation (5G) wireless technologies as wireless gadgets continue to hit the market for being one of the most efficient tool used in everyday life.

According to Dr. Wong, wireless researches continue to evolve to improve communications. Unlike previous wireless Generations (G) which only focuses on a person-to-person kind of communication, 5G is aiming to reach a more advanced level of communications.

“What's big about 5G is extending a machine-to-machine and human-to-machine world. Think about the smart factor, a self-driving car. So that's one thing that a 5G network wants to enable,” Dr. Wong said. “Fifth-generation technology changes the paradigm. It adds two main thing – enhanced mobile broadband and Internet of Things (IoT),” he added.

Dr. Wong is the Senior Group Manager of the Advanced Wireless Research group at the National Instruments where he leads the company's 3GPP and 802.11 wireless standards strategy and platforms for wireless system design, simulation, prototyping, and implementation. Based on the Phase 1 of their research, 5G is considered to operate in the frequency range from 3 GHz up to 30 to 40 GHz. When it comes to the bandwidth of such technology, it ranges from 200 MHz up to 800 MHz. Phase 1 is expected to be finished by December of the current year.


On the other hand, Phase 2 of the research will include extending the technology into higher frequencies even beyond 40 GHz and increasing the bandwidth even further. The 5G technology is also expected to tackle more applications like massive IoT.

“At NI, we've been working with wireless research for quite a while. We want to further wireless research to prototyping. We work with a lot of academic and industry institutions. It's really would be a great opportunity for UP and DOST-ASTI to be part of this, of us working together on this wireless research”, Dr. Wong said.

5NI’s Universal Software Radio Peripherals are software defined radios which can be used for massive MIMO testing

Two of many technologies that play major roles as 5G rises to a milestone are the NI's Massive Multiple Input Multiple Output (MIMO) and Millimeter Wave (mm Wave). Massive MIMO utilizes multiple antennas and advanced signal processing techniques that targets multiple users simultaneously while reusing the same time and frequency space. The mmWave Software Defined Radios, on the other hand, has features that can be effectively utilized from channel sounding to communications prototyping. Such technology has flexible sets of modules that allow engineers to innovate on a faster rate.

“The mmWave is pushing up the frequency to really go up beyond the base stations sites. It goes from 24 all the way up to potentially 70, 80, or even 90 GHz, and use that for mobile communications. That's something totally new for mobile industries,” Dr. Wong explained.

Meanwhile, Dr. Joel Joseph Marciano, Jr., Acting Director of DOST-ASTI, ended the talk with an encouragement to different sectors and organizations to take interest and work together towards researches, technologies, and developments about 5G.

Dr. Marciano, Jr. concludes the activity with inspiring message, encouraging students and professionals who attended the said activity, to pursue researches on 5G and wireless technologies, and promote collaborations with the academe, industry and government.

DOST-ASTI has plans to pursue researches in utilizing Software Defined Radios for various applications such as Spectrum Sensing, Alternative Backhaul System for Global System for Mobile Communication (GSM), etc.

Dr. Marciano, Jr. concludes the activity with inspiring message- encourages students and professionals who attended the said activity to pursue researches on 5G and wireless technologies and promote collaborations of the academe, industry, and government.

The said talk was also in cooperation with Wireless Communications Engineering Laboratory (WCEL) and University of the Philippines Diliman Electrical and Electronics Engineering Institute (UP-EEEI) and was attended by students from various universities and professionals of related fields such as Analog Devices, Inc., ATEC Philippines, Automated Technology (Philippines) Inc., Cirtek Advanced Technologies and Solutions, Inc., DOST-ASTI, Entropy Solutions, UPD-EEEI, and University of the Philippines Los Baños (UPLB).The 5G technology is expected to be deployed by 2020.
