Satellite Technology
This
technology introduces a truly efficient, simple set-up, broadband delivery,
which will accelerate the Philippine entry into the new economy. The
need for a high-speed broadband service is critical since existing telephone
company infrastructures can only support a 28.8 kbps connection via
modem on the side of the end user. An ISP on the other hand will only
have a maximum T1 (1.54 Mbps) connection to the Internet backbone.
TBGI employs
a satellite technology to develop the proposed nationwide data backbone
that can act as a pipeline for ISPs, government agencies, and corporations.
The main function of this service is to provide users ready access to
the information super-highway at a minimal cost to the TBGI clients.
TBGI has
put together a simple yet effective systems infrastructure that presently
makes use of the Mabuhay GEO satellite. The Summit NSP Tower utilizes
its superior electromechanical and telecommunications infrastructures,
consisting of 3,500 KVA power transformer and generator, 10,000 line-ready
telephone lines, structured cabling with fiber optic backbone, communications
tower more than 1,000 ft. above sea level with no signal obstruction
in all directions, etc.
Mabuhay’s
Agila 2 satellite provides the widest and most powerful C-band coverage
over the Asia-Pacific rim including China, Hong Kong, Bangladesh, India,
Indonesia, Japan, Korea, Singapore, Thailand, Malaysia, Mongolia, Myanmar,
Nepal and Vietnam. Operating with an equally powerful spot beam over
Hawaii, Agila 2 essentially links Asia with the US mainland.
Mabuhay’s
Agila 2 operates with high-powered SS/Loral FS-1300 satellite with 24
standard C-band, 6 extended C-band, and 24 Ku-band transponders. Mabuhay
maintains control facilities in Subic Bay and back-up facilities in
Zamboanga, Philippines.
TBGI-Clark
is a full broadcast/multicast and transmitting/receiving satellite earth
station. It is situated in a one-hectare Special Economic Processing
area surrounded by a natural and effective wall blocking out interfering
signals. Equipped with highly sophisticated data/video/audio processing
equipment and power backup, it receives all microwave and E1/T1 signals
from international carriers, and beams it to the Mabuhay GEO satellite
transponders.
The GEO
satellite transmits the signal to South East Asia via satellite
footprint and to the Hawaii Earth Station via spot beam. From the
Hawaii Earth Station, the signals originating from TBGI-Clark, Pampanga
will be sent to the US mainland Internet backbone, the World Wide Web.
Incoming data or downloads will go through the same route in reverse
order.
With
its acquisition of the satellite data communication system in the first
quarter of 2002, TBGI has implemented its broadband satellite services.
The system is the newest two-way broadband communication system for
Internet Protocol (IP) over Satellite released by Viasat Corporation
of the USA.
The Very
Small Apperture Terminal (VSAT) technology offers broadband connectivity
and bandwidth efficiency in a low-cost terminal to support applications
in Internet access, virtual private networks, distance education, digital
media streaming, corporate intranet and extranets, video conferencing,
Voice Over Internet Protocol (VOIP), multicasting, and other IP-based
services.
With this
satellite data system its a scalability and high-performance IP system
provides high bandwidth satellite forward and return channels. The system
offers broadband-on-demand IP multi-service accesses from the central
hub in Clark, Pampanga to remote locations with an asymmetric broadband
multi-frequency TDMA return channel. This sytem enables Global Service
Providers, and Internet Service Providers (ISPs) to offer broadband
Internet access by leveraging the unique advantages of satellite-based
networks in providing point-to-point transmissions.
This system
is capable of operation as a star network in either loop-back or split-beam
mode; the network consists of at least one Hub location and Return Channel
Satellite Terminal (RCST) in remote locations. The network elements
include:
• Network Control Center
• Linkstar Hub, which includes outbound, inbound and timing components,
Gateway Channel Unit or demodulator, and TCP accelerator,
• Linkstar terminal at remote locations
• Linkstar Outdoor Unit, which includes the radio frequency terminal
and antenna, and
• Provisioning for the Linkstar system.
