Dedicated Satellite Communications
Provide A
Backbone For Your Business

The effectiveness of dedicated satellite communications networks as a primary communications tool or as a secure backup connection ensures a real time link between data and operations centers even in the most remote regions of the world.


SCPC satellite backbone connectivity provides constant dedicated communications to deliver one way, full duplex or asymetrical service in point to point, point to multi-point, star, mesh, or hybrid network configurations.


In these designs, an SCPC network can deliver high bandwidth to easily support the most demanding service applications, such as, video-conferencing, voice communications, and data transmission.


This versatility has created a greater demand for dedicated satellite communications worldwide among medium to large ISPs, large businesses, call centers and commercial operations utilizing high data rate or real time traffic intensive applications.

Note: If you are a small ISP operator (less than 2,000 subscribers), there is a hybrid connectivity solution available for you called iDirect enabled backbone service that performs comparably to scpc service, and ... it can save you up to 50% in operating costs! Learn more

A varied subscriber base for dedicated communications links includes medical communities, hotel and hospitality industries, governments, military operations, educational institutions, as well as, corporate and enterprise networks around the globe.


Important Satellite SCPC features

• Supports true multimedia capabilities - voice,video,data
• Replacement of terrestrial circuits
• Backup circuits for redundancy or diversity
• Remote access where high-speed terrestrial connectivity is not available


Potential SCPC applications

• High-speed access to IP networks
• Credit authorizations and inventory management
• Corporate operations and account management
• WAN connectivity


Dedicated satellite service is usually available over two frequency bands - C and Ku. C-band has a wide beam which affords global coverage. Whereas, Ku band offers a narrow, spot beam intended for regional service. Overall improvements in operational equipment and routing features such as Quality of Service, Header Compression and Payload Compression have contributed to the availability of more cost-effective bandwidth and excellent service quality.


Here's a look at various SCPC network service configurations....

Point-To-Point Dedicated Satellite Communications provide a direct link between two sites that are located on the same satellite footprint. Depending upon the satellite and provider, some links can deliver high bandwidth speeds of up to 155Mbps which is comparable to a terrestrial leased line connection. These networks easily support voice, video, and data transmissions utilizing a standard data/voice multiplexer, an SCPC satellite modem, and a VSAT terminal at each site. This is a very simple approach for point-to-point networks as communications are only between the two sites. Similarly, Point-To-MultiPoint satellite connectivity is a network configuration composed of multiple Point-To-Point SCPC connections. There is no connectivity to the teleport which requires the satellite signal to make a double hop. More important, the quality of real time applications is not affected. And, guess what?... there are no costs associated with the usage of a teleport or backhaul which makes this a less expensive solution!

Star Dedicated Satellite Communications or Hub & Spoke service is designed so that all signal transmissions to and from an individual VSAT must be routed through a central location or hub. This network configuration is suitable when a large number of VSATs transmit a large number of low bandwidth intensive transactions that are organized at a central location (hub). Typical applications for Star networks are corporate networks with a Headquarters and remote offices, credit card verification and inventory control.

Mesh Networks allow several VSATs to communicate with each other via a single relay link through the satellite. The "single hop" nature of this network design leads to a minimal time delay between signal transmission and reception. Historically, mesh networks have been an expensive application to provide dedicated satellite communications. However, modulation and compression improvements have helped to make this service more cost effective. Mesh technology is best used for a group of VSATs that need to have real time applications between each site without the latency created by a double satellite hop with communications going through a teleport.

Hybrid Networks are the result of a combination of mesh and star networks used together to achieve a unique form of dedicated satellite communications to meet the service needs of the subscriber. In a hybrid situation, some of the sites can be configured as Hubs in a Star network and the remaining sites as a Mesh network. Alternatively, a VSAT may be part of a Star network and part of a Mesh network concurrently. Each hybrid network application provides an optimal design and solution to effectively provide high speed bandwidth as needed.

How can you reduce network operating costs?

Regardless of network configuration, two of the most important pricing factors for dedicated satellite links are modulation (signal) and spectral (bandwidth) efficiency. These are also essential to reduce the power and bandwidth requirements for reliable data transmission.


A provider may use 8-PSK and 16-PSK/APSK or 8-QAM modulation along with LDPC (Low Density Parity Check) or TPC (Turbo Product Coding) simultaneously to optimize power and bandwidth performance for any transponder. However, it is their ability to use these technologies effectively in combination that can result in more efficient service and cost savings for the end user.


Those service providers offering a choice of modulation, code and code rate in combination can save your network operation money without sacrificing performance. One provider currently using these powerful technologies to maximize throughput and reduce monthly operating costs effectively is BusinessCom.
