»» QSat™ Applications:

AIC’s QSat service is well suited for today’s broadband applications. Service providers offering Virtual Private Networks (VPNs) and multinational corporations can establish extremely economical star networks using one VSAT platform. Ideal QSat network applications include Internet Service Provider Access, Private Corporate Networks, Virtual Private Networks, telemedicine, Voice Over IP, and distance education.

» INTERNET SERVICE
QSat is designed to support large volumes of asymmetric traffic, making it ideal for Internet Service. Clients can increase coverage beyond metropolitan areas, low-cost broadband IP delivery over satellite becomes increasingly valuable.

Exhibit 1: presents an Internet service application using one or more high capacity (36 Msym/sec (60 Mbps)) carriers designated as outbound, and several smaller carriers (156.25 to 25001 ksps (128 kbps to 2048 kbps)) designated as inbound. The outbound carriers are used to broadcast IP content to all Point-of-Presence (POP) locations, each of which serve a large community of dial-in users or a large corporate user. The inbound carriers are shared among the POPs to transport requests to the content-provider. POPs can also use the inbound carriers to send administrative traffic (e-mail, technical support, status reports, request for spare equipment, and voice calls) to the Hub in a single satellite hop.

» PRIVATE CORPORATE NETWORKS
Private multinational corporate networks have diverse application requirements, including file and image distribution, inventory control, video conferencing over IP, e-mail, database backup, image transfer, digital video broadcast, and Voice-over-IP.

Exhibit 2: shows a typical QSat configuration for a private corporate network. A QSat Hub may be located at the company headquarters. The QSat remote terminals are located at the company’s remote sites (sales offices, distribution centers, and manufacturing plants).

» VIRTUAL PRIVATE NETWORKS
A customer, upon deployment of a Hub, can use QSat to establish IP-based broadband Virtual Private Networks (VPNs) for their own multiple clients. Each client’s network consists of the “shared Hub” plus small low-cost remote terminals at each client location. The customer connects its client’s corporate headquarters to the shared Hub, typically via a terrestrial link.

» TELEMEDICINE
QSat is an excellent platform for telemedicine applications because it provides quick broadband, bandwidth-on-demand (BoD) access. Telemedicine applications require the capability of handling large file transfer (x-rays), video and audio connectivity, video conferencing, document collaboration over the Internet, and e-mail. In a typical telemedicine configuration, shown in Exhibit 4, a QSat Hub can be located at a university medical center. QSat remote terminals are located at sites in partnership with the university medical center, including other hospitals, clinics and family health centers.

» VOICE OVER IP
With the competitive nature of Internet access, customers are seeking additional ways of increasing revenue by offering new services such as Voice-over-IP (VoIP). The QSat network, with a low-cost remote terminal, is an ideal platform for delivery of VoIP.

To provide this service, the customer connects a Hub to a VoIP gateway and into the PSTN (Public Switched Telephone Network). Remote POPs accept VoIP traffic and deliver voice traffic to the PSTN through the QSat network, as shown in Exhibit 5.

» DISTANCE EDUCATION
Distance education networks utilize many technologies and various applications, such as video conferencing over the Internet, audio and video streaming, e-mail, and file transfers. Exhibit 6 shows a typical QSat configuration where the Hub is located at the academic institution, and the terminals are located at remote training centers and school locations. The typical remote terminal interfaces with many students over a local LAN. The user may be connected to a PC or to application-specific training equipment.
