Dedicated satellite communications via SCPC networks are an integral part of large business, ISP, and enterprise network operations worldwide. This is because advanced reliability, security, and flexibility enable SCPC (single channel per carrier) satellite service to provide vital, private communications links over VSat networks in a variety of operating configurations.
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. Dedicated bandwidth connectivity is offered on SCPC, iSCPC, DVB and DVP-S2 platforms.
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
This hybrid service performs comparably to SCPC service, and ... it can SAVE you up to 50% in operating costs!   Learn more about it here.

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. More about C and ku frequency bands.
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.
Perhaps, the most efficient systems used in the delivery of dedicated satellite communications are from iDirect. They are fast, dependable, and cost-effective. Read more about iDirect systems.
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 Networks 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. The efficiency of star toplogy networks in delivering dedicated satellite communications services can be greatly improved with the use of DVB-S2/ACM technology that's featured with the new iDirect Evolution X3 router.
The X3 router is specifically designed, with the use of Adaptive Coding Modulation (ACM) on the outbound channel, to optimize the efficiency of satellite capacity. This in turn enables increased capabilities for an iDirect supported star network. Learn more about the advantages of using this new technology together with iDirect satellite routers for your star network. (link opens new browser window)

 Mesh Networks Dedicated Satellite communications 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 Dedicated Satellite Communications
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. Additionally, the use of these powerful technologies can maximize throughput and reduce monthly operating costs effectively.
One such provider who employs these technologies in the delivery of service worldwide is BusinessCom. Another provider, specializing in dedicated services for the continent of Asia, Australia and islands of the Pacific, is Oceanic Broadband. If you're thinking ...
