IEEE Seminar on Digital TV

IEEE Seminar on Digital TV

This year IEEE Indonesia Section and its chapters plan to intensify seminars & lecturing in several cities in Indonesia. Since last year, its Communication Society (Comsoc) Chapter had conducted a seminar series on 4G Mobile Technology. While still running it, now we start another series in parallel (series in parallel, haha). So today we carry out a seminar in the new series: Digital TV. As the previous series, this one also commenced in Bandung; this time in the Hotel Nalendra, Cihampelas.

The seminar is still going on now. It is amazing to see the participants who attend the seminar today. From Mrs. Kusmarihati of Mastel (previously, she was Telkom’s Director of Development, CEO of Telkomsel, and Chairperson of BRTI), some Heads of Department and officials from Universities (Universitas Hasanuddin, Universitas Ahmad Yani, Maranatha University, ITENAS, IT Telkom), the representatives of the operators & providers (Telkom, XL Axiata, DAAITV, Nasio), and several other professionals. Heavy enough:).

The materials in this seminar:

  • Muhammad Ary Murti, IEEE as a Professional Organization
  • Arief Hamdani Gunawan, Digital TV & IPTV Network
  • Kuncoro Wastuwibowo, Video Coding, Compression, & Formats
  • Prasetya Irwan Gunawan, Quality of Service & Quality of Experience
  • Satrio Dharmanto, IPTV Implementation in Several Countries

I guess it is because of the weather of Bandung, with a combination of warm sunshine over chilly air, the discussion took place very warm. Or hot. We were not only arguing about business implementations and engineering decisions, but also the decision to select some mathematical formula. Why do we use DCT instead DFFT? Haha. Funnily I had an answer for that one :D.

This seminar is also supported by Multikom as a sponsor. Next Digital TV discussion will be delivered in the form of lecturing at Bina Nusantara University next weekend.

WiMAX II

On November 21st, the IEEE Comsoc Indonesia Chapter will conduct a seminar to introduce the aspects of 4G Mobile Communications. The seminar will be carried out in Horizon Hotel, Bandung. You might visit Comsoc’s website to see the detail information. I will start the discussion by exploring the necessity of the items mentioned in 4G requirements. Then we will discuss the candidates of the 4G platforms: the LTE, the UMB, and WiMAX II. But we know UMB has been revoked by Qualcomm who then chose the LTE way :). I have blogged LTE a couple times in my other blogs. But it is Arief Hamdani who will explore LTE in details then. My duty is to describe WiMAX II.

You might have known the standard IEEE 802.16e, a.k.a. the Mobile WiMAX. This is the standard for the first mobile broadband access solution that enables the convergence of mobile & fixed broadband network through a common wide-area radio access technology and flexible network architecture. The OFDMA transmission is used for both downlink and uplink. WiMAX II, or  the incoming standard IEEE 802.16m is the amendment to develop an advanced air interface to meet the requirement of ITU-R / IMT-Advanced for 4G systems. The data transfer rates will reach 1 Gb/s, but it must have full backward compatibility with existing Mobile WiMAX. The protocol stacks of WiMAX II is as follows:

WiMAX II Protocol Stack

The objectives and advantages of WiMAX II are, among others:

  • Multi hop relay architecture
  • Self configuration
  • Advanced single-user / multi-user multi antenna schemes and interference mitigation techniques
  • Enhanced multicast broadcast service
  • Increased VoIP capacity
  • Improved cell-edge user throughput
  • Support of vehicular speed (? 500 km/h)

To discuss deeper on the issue, I invite you to attend the seminar. Visit the IEEE Comsoc site :).
