A (Possibly) New Competitor for Matrix and Jakabare

A competitor or a friend ? :-) It could actually be a potential partner if you want to connect to Western Australia!

I don't remember precisely how, but yesterday my Firefox browser took me to Ochre's website. Honestly, I've never heard Ochre before, so I was a bit surprised; similar to the moment where I read about the MCS project for the first time.

Jakarta Metro Backbone

It seems that everybody in Jakarta want to have his own metro :-) Currently many companies have built their metro infrastructure to support their business, particularly in big cities such as the Greater Jakarta, Surabaya, Medan, Bandung etc. These include :
  • well known telcos (TELKOM/TSEL, ISAT, XL, other?)
  • successfull ISPs (BizNET,CBN, other?)
  • VSAT network operators (CSM, Lintasarta, other ?); and
  • backbone operators (ICON+,PowerTel,Napinfo,Moratel, other ?)
Recently, PT. iForte Solusi Infotek announced, that they have finished the construction of their fiber optic network which is using (and installed simultaneously with the development of) the TransJakarta busway infrastructure (map see below). They currently offer connection/access services called M-Wifo which are basically WiFi (802.11n compatible) access and fiber bridging. To my guess, it might be a RoF (Radio over Fiber) system.

Bandwidth "Under Water"

As Asia NetCom (currently PACNET) introduced its idea for EAC Pacific one or two years ago, they underlined the fact that due to underserved routes from South and South-East Asia, Japan-US connections have become a bottleneck. They have shown a picture similar to one below. It has attracted my attention since it split Asia into three regions together with their connectivity parameters. At least, it was something different than we might see in the free version of TeleGeography's reports/databases :-D CMIIW!

After a closer look at the given bandwidth figures and comparing with other publications (TeleGeography etc.), I have to conclude that it isn't real i.e. ANC possibly gave the capacity based on design numbers (fully equiped system). Right ?? Wrong ??

Trans-Pacific Express (TPE) Cable System

TPE (Trans-Pacific Express) is claimed to be "the first next-generation undersea optical cable system directly linking the US and China" and "the first major undersea system to land on the US West Coast in more than seven years". TPE will have a more than 60 times the overall capacity of the existing cable directly linking the US and China, and thus it will be a major enhancement to the current cable systems between these nations.

TPE links China (Chongming and Qingdao), South Korea, Taiwan, and USA (Nedonna Beach). TPE is owned by a joint venture (ownership is evently split) between 6 telcos: China Telecom, China Netcom, China Unicom, Chunghwa Telecom, Korea Telecom, Verizon Communications, AT&T and NTT (the two latest joined in 03/2008).

How Much Bandwidth do Indonesian ISPs Have ?

Though there are many Internet and NAP service providers running their business since several years ago, "big Internet pipes" are only owned by the (former-telco-only) giants: Indosat, Telkom, Excelcomindo, and Telkomsel. They may have a total international IP bandwidth more than 1 Gbps. Unfortunately, as usual :-D I don't have complete, official, clear, and confirmable numbers for that. Maybe next time, I would come with a simple calculation using several rough statistics found in the media and balanced with some cases (personal experiences).

Unity Cable System

Unity is a new multi-terabit transpacific cable system with Google's taste :-D As you can see at this post, I've misunderstood that EAC Pacific would completely be a new transpac cable. It shall actually be a part of the Unity cable. To my knowledge, there are currently three competing parties offering new Asia-US connections:
  • Trans-Pacific Express (TPE) : Verizon's Taste :-)
  • Asia America Gateway (AAG)
  • Unity : PACNET, Google etc.
Any other planned cables ?

PT. Power Telecom (PowerTel)

Is there any relation between PowerTel Indonesia and PowerTel New Zealand/Australia ? Honestly I've just heard about this company a few months ago and about last week I was quite surprised when several media quoted the company press release that they are ready to offer services in Jakarta Bandung and that they are in the last stage of the preparation of Java-wide fiber optic infrastructure. Well, "Gut gemacht! Gratuliere!"

Facts and quotes:

Mobile Network Coverage : Telkomsel

As of Q2 2008 PT. Telekomunikasi Selular (Telkomsel/TSEL) operates 23,056 BTSs (including 3G) and serves 52.44 mn subscribers (4% postpaid, 96% prepaid). 4.55 mn of those are new customers this year. As of Q2 2008 TSEL customers spent totally 32.1 bn MoU (Minutes of Use), which is equivalent to 178+ mn MoU each day. It is claimed that the current TSEL network can handle up to 54.8 mn subscribers.

PGASKOM (PGAS Telekomunikasi Nusantara)

It is not easy to find information for PGASKOM's backbone. PGASKOM is subsidiary of PGN (Perusahaan Gas Negara) which provides connection services using its fiber optic infrastructure currently installed along its gas pipes spanning from SG/Batam to Southern Sumatera (in the near future to Cilegon Banten and maybe to Jakarta). In an indirect press release several times ago as recorded by local newspapers (detik.com/bisnis?), PGASKOM shall have 96 core / 24 core fiber for terrestrial and submarine segments, respectively. Several cores shall already be leased by (some incumbent) telcos. Anybody knows more ??

New Asian/Transpacific Submarine Cables

In addition to AAG, several new cable systems in/via Asia are developed (just commissioned or currently under construction). This includes :
  • Trans-Pacific Express (US-China)
  • FLAG NGN (Intra-Asia, Intra-Africa, Mediterranean, Trans-Pacific)
  • IMEWE/TIC (Japan, Hong Kong, Singapore, India, Europe)
  • East Asia Crossing (EAC) Extension

National and Regional RENs

Actually since a long time ago I want to write threads about RENs (Research and Education Networks). Why? Simply because they were the origin of the current Internet and they still have a major role in creating advances in networking technologies. This time I would not start with an indonesian case (if INHERENT or Jardiknas can be categorized as a National REN/NREN), but with european cases.

Excelcomindo's Backbone

As of Q4/2006, Excelcomindo has installed and operated more than 2,300 km submarine and more than 5,500 km terrestrial fiber optic cable. This information can be used to check or balance my former calculation (however this was for Q4/2007, since it is based on the information from Kominfo on that time frame). I'm just thinking to derive a progress factor, something like fiber deployment rate each year each operator (km/year), just to have a rough metric for measuring operators' progressivity. Whether somebody out there (in Kominfo or in the operators) is already doing this??

Mobile Network Coverage

How many BTSs are needed to completely cover a city on average? 50 ? 100 ? more/less ? If each operator has its own tower, then it would be 250 to 500 towers in a city (assuming there are 5 operators, 1 BTS each tower).

Around two years ago, when I came back from Germany after several years leaving, almost every 1 minute or maybe less of my trip from Jakarta to Bandung (also inside the cities) I saw a BTS tower!! Several times later people told me that indeed due to "cellular wars", our cities have turned into "Hutan BTS" (BTS forrests). Well this is the fact. This might:

Indosat's Backbone (2)

I've just found another version of Indosat's backbone. For me it looks a bit better than the previous one, though some links might still be not so accurate.

Asia America Gateway AAG (2)

One day in 2007 George McLaughlin has mentioned AAG as a possible infrastructure for supporting future Asian networks (APAN - in the context of RENs). It shall at the begin this year a decision whether or not APAN acquires a stake in the consortium. Since the Hengchun's earthquake many people see AAG as a potential infrastructure for increasing network reliability between (South/South-East) Asia and the USA, since it uses different routes than the usual Asia-US submarine cables. AAG also plays an important and strategic role that it can be extended to other countries/continents, thus increasing network reliability at a global scale (see the pic below).

Palapa Ring (5)

The last non-incumbent member of Palapa Ring consortium, PT. Powertek Utama Internusa has indirectly cancelled its membership (update to this post) . Thus the consortium currently consists of the four-biggest telcos:
  • PT. Telekomunikasi Indonesia (Telkom)
  • PT. Indosat
  • PT. Excelcomindo Pratama
  • PT. Bakrie Telecom

First Generation Domestic Optical Cable Systems

PT. Indosat has begun to deploy submarine cables since 1985 (optical?). PT. Telkom on the other side has stated that the TIS cable is its first optical submarine cable system.

Recently, according to ASN record, Telkom has already deployed an optical submarine cable system in 90s. Which is true ? Is it only the matter that TIS is international while the other is domestic ?

Highlight XL (Excelcomindo)

In this new "Highlight" thread, I would archieve some actual facts (of my interest) related to indonesian telcos/ISPs.

Currently, XL (Excelcomindo Pratama) is the third largest telco in the country. This is currently justified if we look at the customer base and some financial performances of the company. The current champion is Telkom Group (inc. Telkomsel) while the "vize" champion is Indosat Group. The position might change in the (near) future, especially since XL "moves" quite progressive after TM acquisition and after the former Indosat CEO Hasnul Suhaimi leads this company.

International IP Bandwidth

Currently I have only some official information specific to Indosat. This was presented by Indosat several times ago (Apricot 2006 Bali ??). However, it belongs to the "biggest" pipes owned by indonesian ISPs.

Indosat's IP Transit Bandwidth:
