Results in Physical Layer
Homebrew 2Mbps CDMA.
 Wireless Data Network.
 VSAT TDMA vs. SCPC Network.
 Fast Ethernet Test Bed.
 Low Cost Access for Schools.


Institute of Technology Bandung

Homebrew 2Mbps CDMA
Uses Lucent CDMA 2Mbps card 915MHz
250mW.
 Run on FreeBSD.
 Homebrew antenna (cost ~US$150).
 Max. distance 15km (use PA for more).
 Most of our high speed MAN using this
technology.
 contact cnrg@itb.ac.id.


Consequences CDMA2Mbps
bypassing local line.
 FYI, Indonesia currently have only 300
N-ISDN lines in operation.
 We promote diffierent alternative for
building high speed network.

19.2Kbps.
 Internet Access.
 Interface to FAX.
 Interface to Pagers.
 Interface to Short Message Services
(SMS)


Institute of Technology Bandung

Homebrew 64-256Kbps packet
radio
We are prototyping 64-256Kbps packet
radio network in the lab by
adnan@itb.ac.id.
 AX.25 link layer protocol is used.
 GMSK MX 586 one chip modem is used.
 We drive the modem via parallel port.
 MMIC Minicircuit is being build for
transverter.


Institute of Technology Bandung

Fast Ethernet Test Bed
Supported by Intel.
 Test Intel Fast Ethernet board to run on
FreeBSD.
 This test bed is driven by our
overloaded MPEG-3 traffic :-)....


Institute of Technology Bandung

Low Cost Access for Schools
AX.25 1200bps Packet Radio Network.
 Proxy Server.
 Dial on Demand for Web & Interactive

VSAT TDMA vs. SCPC
VSAT TDMA 128Kbps Outbound
 VSAT TDMA 64Kbps Inbound
 VSAT TDMA is not suitable for Internet
application (especially Web).
 Tune TDM for 40 byte (originally 256byte
packet).
 Migrating to VSAT SCPC 19.2Kbps at
least.

Results in Network Layer
Network Monitoring by
ismail@cnrg.itb.ac.id.
 Monitor at http://netmon.itb.ac.id/


• Network Map
• Sample of traffic by protocol, port, etc.
• Graph of total traffic.


Migration to OSPF for internal routing.

Cache
ITB has set 4 Parents.
 Cache person is husni@itb.ac.id
 We cache all of our Web traffic.
 May be our cache machine is the
bottleneck.
