FACTS (30 October 1994)

  •	It is a three years old self-supporting network with an estimated growth rate at least 700% per year.

  •	A total of 64 nodes are in operation with 44 (69%) of which are located in Bandung; the rest (31%) are spread all over Indonesia including Jakarta.

  •	Most of the nodes (80%) are using the low cost packet radio technology to form a WAN, the rest (20%) mostly in Jakarta are using dial-up UUCP / TCP/IP to reach the InterNet gateway at IPTEK-NET Jakarta.

  •	Nearly NONE of the node is using the Indonesian commercial packet switching network (SKDP) to reach IPTEK-NET gateway.

  •	In addition to the active nodes, there are currently at least 45 nodes are preparing their equipments and human resources to join the network.

  •	Estimated total number of users is 2013 users with approximately 78% resides in Bandung (66% are users of ITB).

BEBERAPA APLIKASI UTAMA JARINGAN KOMPUTER

  •	Electronic Mail
	  	Perkiraan traffic ke luar negeri 500Kbyte / hari.

  •	Electronic Conference
	  	Total mendekati 20 buah konferensi elektronik yang berjalan secara simultan 24 jam.
	  	Paling tidak 2 buah konferensi terhubung ke konferensi elektronik yang berjalan di luar negeri.

  •	File Transfer
	  	Paling tidak ada 7 buah FTP site utama di jaringan (4 diantaranya di Bandung).
	  	Perkiraan total file yang dapat di FTP adalah 3 Gigabyte.

  •	Telnet
	  	Fasilitas remote login.

  •	Database akses
	  	Paling tidak ada 4 buah Gopher server utama di jaringan.
	  	Isi terutama hasil-hasil penelitian.

Subject: Indonesia's Microsat

Dear Dr. Onno,
thank you for your interesting message dated June 13th.
We are highly motivated to collaborate with you in the Microsat field. Could you send us some preliminary frame specs of the project? Do you consider exclusively communication payloads or do you think along a broader possible spectrum like athmospheric / ionospheric research, remote sensing etc.?

We are in principle ready to start PACTOR Tests on HF with 100 Watts and a 5 Element beam.

Will meet Horst Clausen on 20 June to discuss with him possible contributions from his institute.
Best regards
Gerhard

Hello Dr. Onno,

thank you for your message. I have forwarded it to Dr. Mayer and a friend at the Technical University in Graz, Austria, who is a specialist in satellite communications. We will investigate our possibilities and report back to you within the next days.

Best regards,
