National and Regional RENs 2008-08-17 23:11:30 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.
New Asian/Transpacific Submarine Cables 2008-08-17 20:03:03 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
From a certain point of view EAC transpacific might offer a better Read more:Asian

Mobile Network Coverage 2008-08-17 18:04:06 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 Read more:Mobile

Excelcomindo's Backbone 2008-08-17 16:59:00 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
First Generation Domestic Optical Cable Systems 2008-08-16 19:00:06 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 ?

Indosat's Backbone (2) 2008-08-16 18:41:00 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) 2008-08-16 18:40:49 One day in 2007 George McLaughlin has mentioned AAG as a possible infrastructure for supporting future Asia
n 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 Read more:America

Palapa Ring (5) 2008-08-16 18:40:08 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. IndosatPT. Excelcomindo PratamaPT. Bakrie Telecom
According to the consortium, Powertek hasn't fulfilled its commitment as stated in the CCMA
High Performance BackBone (HPBB) 2008-08-15 18:05:12 HPBB functions as the main backbone of PT. Telkom in Sumatera. It connects the following places:

Indonesian DSL Market 2008-08-15 18:04:54 The title might be broader than I could write here right now. However, as usual, the thread will be continued later if I get some new interesting information.

Can Broadband Spread to the Masses? 2008-08-13 21:48:30 In this post, I just want to archieve some facts and opinions given by Arjun Trivedi (NSN-Nokia Siemens Networks) in the first Indonesian Broadband Summit held last April in Jakarta.

Indosat's Backbone 2008-08-13 17:39:36 In this post I just want to put some additional information (maybe "another view") of the Indosat's backbone mentioned in the this post. The map below was presented by Indosat in Apricot conference several times ago (2006, in Bali I guess). Does Indosat use any consortium's cables (SMW, APCN) just to link to Singapore ?
TIS Cable 2008-08-13 16:24:36 TIS stands for Thailand Indonesia Singapore. As indicated by the name, it is an optical submarine cable spanning from Songkhla (Thailand) to Batam (Indonesia) via Changi (Singapore). TIS cable was the first submarine cable project of PT. Telkom.

Jasuka 2008-08-11 03:51:28 Jasuka (Jawa Sumatera and Kalimantan) backbone is owned by PT. Telkom and was operated since early 2006. It consists of 2 rings and connects 30 cities in the islands including
Ring 1 : Jakarta, Tanjung Pakis, Tanjung Pandan, Pontianak, Batam, Dumai, Pekanbaru, Jambi, Palembang,Baturaja, Bandar LampungRing 2 : Medan, Tebing Tinggi, Rantau Prapat, Pekanbaru, Bukit Tinggi, Padang, Sibolga, Pematang
Wiring Kalimantan 2008-08-10 15:49:06 As in the case of Sumatera, the biggest three telcos are developing their optical transmission infrastructure in Kalimantan
. As you can see below, they have chosen to follow terrestrial paths approximately parallel to the coastal line of Kalimantan. This might mirror the actual social and economic development in Kalimantan. Festoon optical networks could still be possible to be deployed as backup
National Fiber Optic Backbone 2008-08-09 08:48:15 How does Indonesia's backbone currently look like ? How many kilometers of fiber optic cables are laid/buried/mounted nationwide? How are they distributed ? Some of you might already be confronted with such questions. I could not help you with exact answers either :-). But let us make some approximations. If we only consider the three biggest players (Telkom, Indosat, and Excelcomindo), after a Read more:National

Wiring Sumatera 2008-08-08 16:28:51 Looking at the telecommunication infrastructure in western Indonesia, Jawa-Bali and
Sumatera are counted among the bests. Long distance transmission across the island is mainly served by terrestrial fiber optic links, which are approximately described in the picture below. This is based on the infrastructure of the three largest telecom operators PT. Telkom, PT. Indosat and PT. Excelcomindo (
Palapa Ring (4) 2008-08-08 04:27:11 By yesterday (7/8/2008) PT. Infokom Elektrindo has renounced its membership in the Palapa Ring consortium. Thus it now consists of only 5 companies. From several VIPs of the consortium in a press release, several things are revealed:
The consortium has to find funding for around USD 15 mio. previously committed by Infokom; it is (still) assumed that the project's cost is approximately USD 225

Jakabare 2008-08-06 02:50:43 If we look at the route maps published by nec.co.jp and matrixnetworks.sg, it seems that Jakabare and MCS share almost similar route path. I did a rough image matching on both pics; the result can be seen below. Except that Jakabare branches to Pontianak around 70 km (?) from Bangka, they seem just like a twin.
What is actually Jakabare ? Local readers might refer to the comment given by Meneer
Palapa Ring (3) 2008-08-04 00:55:46 It seems that the project is delayed, just like several other submarine cable projects :-)
Below are several issues related to the project as of March 2008 (source KOMINFO - Ministry of Information and Communications) :
