Challenge To develop a new telecommunication infrastructure for the air traffic control system in Mongolia - over a million square miles of mostly harsh terrain with limited communications and electricity infrastructure, and temperatures ranging from -40°C to +40°C Solution DialSat technology answered the challenge by linking Mongolia's 22 airports and relay stations with a cost-effective, solar-powered VSAT network that's completely independent of terrestrial infrastructure. The system enables Mongolia's Civil Aviation Authority to:

• Relay VHF and UHF voice between planes traveling in the vast Mongolian airspace, and the central control tower at Mongolia's capital Ulaanbaatar.
• Provide a private, independent telephone network connecting air traffic control towers using a “hot line” application;
• Provide a private data network to transfer meteorological and navigational data, ticketing information, radar data, and other data links required to operate and aid air traffic controllers
• · Maintain high voice quality and effective data transfer by seamlessly integrating with VHF radio base stations; meteorological systems, radar equipment, and the telephony network
• Remotely monitor and control remote VHF stations, navigational aids, meteorological data and more.

Results
DialSat VSAT-based network has brought Mongolia these important results:· Highly reliable air traffic control, even in remote, harsh environments · Centrally controlled air traffic from the main control tower in Ulaanbaatar across the entire Mongolia airspace Air traffic controllers can talk with any pilot crossing the Mongolian airspace, using VHF relay over the DialSat technology. · Direct reliable communications between the different airports · Access to radar and meteorological data. in all of the air traffic monitoring stations, and the ability to exchange data among all sites; · Significant upgrade of service at the country's international airport; · Reduced operational costs and increased efficiency; · Problems accurately identified and addressed in real time; · Dynamic network architecture that allows for nearly unlimited expansion. "We were searching for a civil aviation communication system that would provide 99.999% reliability. We found that DialSat's VSAT solution not only provides us with reliable communication, but is quickly deployed and the most cost-effective solution for our huge territory." - G. Davaa, Director, Civil Aviation Authority of Mongolia

Challenge To develop an advanced, efficient data communications network for major German financial services company GIS in order to connect 1,800 cooperative banks to the world's leading stock exchanges and financial services organizations. Solution DialSat met the challenge with one of the largest VSAT networks in Europe, a fast-deploying, 1,800-site network that will enable GIS to:

• Deploy a single Internet Protocol ( )-based platform for a wide range of interactive data and video applications;
• Transmit detailed financial information on publicly traded companies quickly and efficiently;
• Broadcast Business TV sessions to remote sites with uniform speed, including internal and industry news, product and application information as well as sales force updates.

Results
This new GIS VSAT network is designed to bring these significant results:

"We have researched a number of new options for network technology solutions and are convinced this decision will achieve the most capability and reliability. We are assured of deploying the most advanced system - one that is optimized for the Internet and one that provides single-platform support for both Token Ring/Ethernet and business television." - Werner Wolf, CEO, GIS

GIS Deploys Advanced 1,800-Site VSAT Communications Network for Financial Services
Single Platform for Wide Range of Interactive Data and Video Applications
For financial service organizations, the need for up-to-the-minute information gives new meaning to the term "mission-critical."

That's why when GIS, one of Germany's largest financial services companies, was looking for a better, more efficient means of connecting 1,800 cooperative banks with world stock exchanges and financial institutions, they turned to.

GIS (Genossenschaftlicher Information's Service GIS GmbH) had a complex set of application requirements that included both data and video, and needed a system that would both be optimized for the Internet and that would provide single-platform support for both Token Ring/Ethernet and business television.

DialSat met the challenge with GIS to deploy Internet Protocol ( )-based interactive data and video applications, including transmission of detailed financial information on publicly traded companies and broadcasting of Business TV content to its remote sites.

Werner Wolf, GIS's Chief Executive Officer, said, "With this VSAT network, financial professionals will have immediate access - via their local remote server - to all the information they need to provide their customers with superior service. Each cooperative bank will receive the same fast, broadband connectivity - regardless of their location in Germany."

The GIS VSAT Network
Reliability and Performance Across the Enterprise, Across Europe the new VSAT network will enable GIS to distribute information from the major stock exchanges around the world to the entire cooperative bank group, primarily its 1,800 regional banks in Germany (with a total of 17,000 outlets in Germany) plus banks in Luxembourg, United Kingdom, Austria and Switzerland.

DialSat's proprietary interactive TCP/ capabilities enable financial services professionals to access a central database with detailed information on most of the world's public companies. As a result, they can instantly provide their customers with detailed company information such as annual reports, stock earnings, quarterly reports and more.

With the VSAT network, the stock exchange data stream - with pre-selected information - is stored and processed at a remote server. Each request for stock information, therefore, is handled remotely and is not transferred to main host.

Additional data can be requested on demand, based on the integrated return channel. That means substantial bandwidth savings and increased application performance.

A sophisticated Business TV application is being used to distribute the latest company information by video. Content includes corporate updates, new product introduction and marketing programs from the banking sector, insurance division and building and loan association.

Future applications may include more interactive TCP/ applications as well as kiosk terminals to Points of Sale and Points of Information.

Rapid Deployment and Full Service
Europe Provides GIS with Total Solution Network implementation began in March 2001, and by the end of May 2001 more than 1,000 sites had already been deployed. The remaining network is forecast for completion in the third quarter of the year. This represents a fraction of the time usually required to roll out a terrestrial network with similar capabilities. Europe's VSAT network solution for GIS includes turnkey installation of all VSAT remote site equipment, as well as comprehensive network operations and field maintenance.

Challenge To provide the USPS with broadband connectivity throughout its potential for 33,000 small associate offices. (not a small task at all, as this is a network three times larger than any VSAT network in existence!) Solution DialSat technology currently provides the USPS with connectivity for approx. 11,000 (with a potential for far more) of its smaller offices to its terrestrial Frame Relay network, giving these locations — and the local residents who depend on them — access to the same products and services available in large metropolitan Post Offices.

The network is used for the following applications:

• Point of Sale · Data polling
• Credit Authorization
• Delivery confirmation
• Software distribution
• Recovery Control (back-up) of the terrestrial Frame Relay network

Results
The installed VSAT network provides the USPS with reliable connectivity throughout its related sites. Its satellite network has also been chosen as the platform to provide its large and small locations with access to emerging applications, including:

• Streaming video
• Interactive distance learning
• Content delivery

Finally, the USPS is using VSAT technology as a more reliable and efficient replacement for the ISDN Frame Relay backup solution it previously used at 7,000 of its large associate offices.

The Attacks of September 11
VSAT technology - A Recovery Control System Using VSATs as a backup for terrestrial systems is a proven and reliable solution. Nowhere was this truer than the September 11 attack in New York. As a result of the attack on the World Trade Center, the frame relay network of USPS’s New York branches became ineffective. Yet, once the USPS pointed its VSAT system in Virginia towards New York, the states’ post offices were back on-line in no time. When frame relay went down, a satellite connection took over.

Challenge Providing connectivity between the 120 dispersed islands of French Polynesia, at a distance of hundreds of miles away from one another and scattered in a maritime area over 4,000,000 square kilometers. Solution DialSat’s Internet Protocol ( )-optimized satellite network ensures that inhabitants receive reliable a reliable means of communicating, via telephone and, in many cases, Internet access. The DialSat VSAT provides OPT with:

• A modern and reliable infrastructure
• Higher performance and availability
• Low maintenance costs

Results
Via a hub in Papeete with traffic terminals connecting the VSAT network to the terrestrial PSTN/Internet infrastructure in Tahiti, VSAT subscribers are able to communicate directly with terrestrial subscribers for incoming and outgoing telephone calls, as well as connecting remote islands to the Internet backbone.

At each of the remote islands connected to the VSAT network, a DialSat VSAT terminal is installed to support voice, fax and high rate data transmission between the remote locations and the hub, and, optionally, directly between the remote locations.

"French Polynesia is comprised of more that 100 islands over a vast area. Many islands are more than hundreds of miles apart from each other. The only feasible method of communication between these islands and Tahiti is via satellite. 's Internet Protocol ( )-optimized satellite network will ensure that inhabitants receive reliable telephone service and, in many cases, high-speed Internet access." - OPT General Manager Geffry Salmon

Telephony and Internet for Remote IslandsOPT:

Serving French Polynesia with DialSat’s Technology
Up until only recently, OPT served surrounding islands with transmission systems based primarily on radio technology. Yet, the need for a more reliable communications solution, the challenge of high operation and maintenance costs and the desire to unify the diverse requirements into one centrally controlled technology led OPT to seek another alternative. This alternative was a VSAT network solution.

In the future, OPT can fully utilize the modularity inherent in the VSAT network to increase the level of subscribers as traffic requirement grows and deployment deepens into additional islands without connectivity.

And, due to the technology’s flexibility, applications, such as fax, Internet & private networking to corporations can all come into play, as is needed.
