VSAT sevice comes with a flat monthly service rate for each installed
site, irrespective of where the VSAT unit is installed. The terms and
conditions of the VSAT service are specified in a standard service contract
agreement. A typical agreement has a contract period of at least two years
and may be extended for a longer period.
the monthly rate is independent of traffic volume or duration of the usage,
our Customers benefit from having a fixed monthly communication costs.
Customers do not need to purchase the remote VSAT unit. We provide the
entire VSAT system including the Indoor Unit and the Outdoor unit that
is ready to be linked to the Customer Premise Equipment (CPE).
part of the service contract, we provide the support and maintenance on
the VSAT system throughout the duration of the contract, which include
spare parts and manpower.
VSAT technology offers many advantages
After the order is placed, putting up a VSAT network can be done in a
matter of days depending on the number of sites. The antenna dish can
be installed virtually anywhere - on rooftops, in parking lots, or on
the sides of the buildings. The size of the antenna dish ranges from 1.8m
to 2.4m in diameter, depending on the type of application.
Likewise, moving the VSAT unit to a new location can be done very quickly.
Once the antenna site has been established, our field technicians will
be able to erect the antenna in hours and usually complete the installation
of the Indoor Unit on the same day.
The wireless nature of VSAT system allows its installation at virtually
any location within the footprint of the satellite. Our current satellite,TELKOM-1
covers from the northern part of Australia to the mainland China. Naturally,
it includes the entire archipelago of Indonesia and the neighboring ASEAN
With this advantage, Customers may setup offices in a promising location
without being constrained by the availability of terrestrial lines. At
the same time, Customers may relocate offices to a lower cost area and
still maintain the communication link with the use of our VSAT links.
Satellite communications is extremely reliable. Our VSAT system has a
Bit Error Rate (BER) of approaching 1 x 10-9. This BER is similar
to that available on many of today's advanced digital terrestrial circuits.
Our historical network uptime is approaching 99.98%, exceeding typical
terrestrial cable lines. Our VSAT Master Earth Station has built-in redundancy
that ensures continuous operations in case of failure.
Regardless of where the sites are located, each VSAT remote unit receives
the same level of performance and signal quality.
Our entire VSAT network is constantly monitored and managed by a qualified
team of engineers at the Network Operations Center (NOC), located at the
Master Earth Station. We are therefore able to detect problems early and
provide quick resolutions before they affect the network continuity.
We remotely manage the remote VSAT equipment that is installed in each
of the Customers' sites. Configuration updates or parameter changes can
be downloaded from the NOC without physical visit to the Customers' sites.
This network management feature gives added assurance to our Customers
that their private networks are in constant care, 24 hours, 7 days a week
throughout the year.
One of the great advantages of wireless VSAT technology is its direct
connectivity between end-points. Every VSAT link is established directly
through the satellite, bypassing intermediate terrestrial lines. Hence,
faulty problems with the network can be identified and fixed quickly.
For hardware failure at the remote earth station, we can bring up the
VSAT unit by simply replacing the faulty module.
For mission critical applications, we are able to provide dial modem backup
system that allows automatic cut-over to terrestrial line for temporary
backup until the VSAT remote unit is fixed.
Satellite networks offer excellent security against unauthorized access.
All transmissions in our VSAT system are scrambled in digital format.
Gaining access to a VSAT system is virtually impossible without authorization.
Every remote VSAT earth station is controlled and monitored from our Network
Banks and financial institutions around the world predominantly use VSAT
system to carry critical and sensitive financial transactions. The Canadian
and U.S. Armed Forces also use VSAT for their communication networks,
further testifying the security of the network.
One of the strengths of our VSAT network is the ability to scale according
to the Customer's requirements with low incremental cost. This is especially
important as business grows over time. A new site can be added to the
network by installing a remote VSAT unit. A VSAT network can support thousands
of VSAT remotes.
Customers may start with data service. Adding more bandwidth over time
can be done by a simple reconfiguration at the NOC (Network Operations
Center). In addition, Customers are able to add voice capabilities or
video applications at a later stage. These add-on services can be done
on the existing VSAT remote unit by installing additional modules to the
VSAT streamlines Customers' communications into one powerful and dynamic
network. Changes in the communication requirements can be adapted quickly
and cost-effectively by reconfiguring the network with ease.
VSAT also gives Customers complete freedom in designing the data network
whether it is based on Centralized or Distributed architecture. The VSAT
network can be tailored to optimize response times to satisfy the application
requirements. Unlike terrestrial networks, there are no geographic constraints
in configuring VSAT multi-point links, thus minimizing network traffic
peaks and transmission capacity.
Our VSAT services bring about cost savings to the Customers. The advantages
of the VSAT technology already give tangible and intangible benefits to
our Customers. As Customers add more services, they will find that the
incremental cost is very low compared to terrestrial networks.
The service costs are distance insensitive. The monthly service fees are
fixed and priced according to the network capacity, not the distance between
the head-office and branch locations. As a result, Customers pay only
for the amount of data throughput used.
companies develop their private wide area networks to interconnect the
network of the remote offices with the main computer center. While data
communications is the primary use of VSAT, there are companies that require
internal telephone network for inter-office communications.
communications can be divided into the following categories:
The interactive applications can be based on centralized or distributed
concept. In a centralized system, all terminals in the offices operate
"on-line" and communicate intermittently with the host or servers at the
data center. These include client-server applications and Web-based intranet
applications. In a distributed system, each remote office has terminals
linked to its local host or servers. The servers then communicate with
each other in a Wide Area Network (WAN). Besides real-time data applications,
our VSAT network supports two-way voice capability for telephone or facsimile.
Remote offices can make phone calls to each other or to the central headquarters,
bypassing the local public phone network.
These applications send a large amount of data in one transaction. These
include the use of the TCP/IP File Transfer Protocol (FTP) to transfer
files and the printing of large reports.
A recent file transfer application requires support of file broadcast
or IP multicast. These applications send the data to multiple sites in
one transaction. Typical applications include audio and video broadcast,
distance learning, data distribution, and software updates. A VSAT network
is inherently broadcast in nature. Thus a VSAT network naturally and efficiently
support these new broadcast applications. Using a VSAT network, a large
file can be distributed to hundreds of sites simultaneously. Our VSAT
network supports IP multicast, which improves broadcast performance even
