SDP Asia Summit

2009-11-12 / / 0 Comments

After long weeks of preparing the Indigo Awards, I flew to Singapore to attend The Annual SDP Asia Summit. The invitation was given by Andy Zain and Andreas Surya of Indonesia Mobile-Monday (id-Momo). I have a couple times talked about SDP with them; and also presented it once in FRESH forum. SDP (service delivery platform) itself is a framework to virtualise network & orchestrate services to make it easier to develop, deploy, sale, get, & use digital services. Unlike IMS, so far there is no standard of SDP. This fact somewhat makes SDP discussion interesting: it is about best practice in infocom business.

SDP-Architecture

Since SDP has no standard, companies could easily make a concept of SDP 2.0 (ala Accenture or Telecom Italia) or even SDP 3.0 (HP version). Also there were some alternatives to map SDP to other infocom management concept, such as SOA, SDF, IMS, and even Web 2.0.

When describing the architecture of SDP 2.0, Telecom Italia explores the necessities for service & network abstraction & virtualisation, including reusability and interface standardisation. Scalability & modularity would include plugins capability. Sounds a bit like Accenture version (I have blogged this version in my Indonesian blog), where the objective of SDP 2.0 is to facilitate a self-service for service developer & provider in commercializing their services & contents.

But then Hewlett-Packard introduces this term: service governance framework. It encourages the use of open standard, reusability, and other issues to ensure an effective SDP implementation. Other issue delivered is the utilisation of data mining toward users profile, applications, etc, etc, to make it SDP 3.0.

In the similar spirit, Telemanagement Forum discusses the linkage to business: SOA, SDP, Web2.0, etc, mainly SDF. Great pictures, indeed. They somewhat remind me to C++ standard template library. Discussions with operators, providers, & consultant who are in progress of implementing SDP in Asia & Europe make the days richer.

I guess then I need to make a presentation to summarize them all, and present it to my colleagues this week. Hmm, maybe after the IEEE 4G session(s).

WiMAX II

2009-11-11 / / 2 Comments

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 :).

Coventry Inspires

As you might know, this is not my first blog, nor my first english blog. But on recent days, when you search «coventry» in images.google.com, you will find the first picture refers to my first english blog: koen.telkom.us. Here’s the picture:

coventry_lighting

The first time I read about Coventry was when I read «The Secret Seven» by Enid Blyton. The idiom «being sent to Coventry» according to the book means being excommunicated. There is a real history about that, actually. But interestingly, then I lived in Coventry to study communications :D. I lived one year in that historical town to pursue my postgrad in telecommunications technology in Coventry University.

Both Coventry and Coventry University have a phoenix as their logo. Also there is a history about that. In World War II, The Luftwaffe has bombed almost all essential part of the city. The city was totally destroyed into dust and debris. But from the ashes, a new Coventry was born. Like a phoenix, it was born from its ashes, created itself with greater spirit. It tied itself with Stalingrad as sister city for solidarity, but then also with Dresden for reconciliation. The spirit of Coventry makes the world believes that even from a great catastrophe we can rise and shine the world. Coventry inspires.

Sometimes I use or wear the picture of the Coventry’s phoenix. It inspires to see the phoenix in me. I am not an all-time winner. But I surely know that each time I fall: I will rise, and I will shine.
