AT&T, Komselindo launch CDMA system
JAKARTA (JP): AT&T of the United States and PT Komunikasi
Selular Indonesia (Komselindo), a private analog cellular mobile
telecommunications operator, launched yesterday a trial wireless
network using code division multiple access (CDMA) technology.
AT&T said in a statement made available to The Jakarta Post
yesterday that the network, located in Bandung, West Java, is one
of the first applications of CDMA interfaces outside of the
United States. AT&T has installed a number of its Autoplex cell
sites for the trial.
CDMA is being adopted around the world as the wireless
industry standard to deliver digital cellular and personal
communications services (PCS) and the system offers economical,
clear and secure wireless communications, according to the
statement.
"The trial system in Bandung allows us to test this promising
new technology in the Indonesian environment," said Komselindo's
president, Soedjono Kramadibrata.
CDMA can increase the capacity of analog cellular networks by
as much as ten-fold and enables service providers to offer
applications and improved service quality to customers. With
CDMA, each conversation is specially encoded and decoded for each
subscriber. As a result, multiple subscribers can share the same
frequency band simultaneously and still hear only their own
conversations.
"CDMA is an excellent technology that reduces overall network
costs and provides exceptional voice quality," president of AT&T
Network Systems Indonesia, Lie Gendo, said.
AT&T Network Systems' wireless equipment group is the only
telecommunications equipment supplier that supports a breadth of
wireless industry interfaces, including CDMA, time division
multiple access (TDMA), Global System for Mobile Communications
(GSM) and Advanced Mobile Phone Service (AMPS).
Komselindo is 65 percent owned by PT Elektrindo Nusantara, an
affiliate of Bimantara Group, and 35 percent owned by the state-
owned domestic telecommunications operator PT Telkom. It operates
cellular mobile telecommunications, using AMPS technology, in
West Java, North Sumatra and Sulawesi. (icn)
