In his recent blog Denis Sutherland, iDirect’s Director of Business Development, points out the challenge facing Satellite Operators when it comes to having the right amount of satellite capacity available in the right place over the lifetime of the satellite. This is critical to the success of Satellite Operators launching High Throughput Satellites (HTS). And managing that bandwidth across multiple HTS spot beams comes with a set of additional considerations for both Satellite Operators as well as Service Providers. Why is that?
Managing HTS bandwidth across multiple spot beams, compared to a single wide-beam coverage is a challenge. It comes down to being able to maintain Service Level Agreements (SLAs) across the entire customer network by managing the network capacity on multiple spot beams as one single bandwidth pool.
Think also about the difference in operational economics that come with multiple spot beams. Service Providers who are only using a few MHz on each beam would need to equip multiple spot beams with ground infrastructure versus just a single wide beam. That’s why we see more Satellite Operators planning to pre-populate multiple spot beams with hubs and line cards to allow Service Providers to cost-effectively operate regional networks. It is for these reasons that we expect to see more Satellite Operators coming down from space to start offering managed services.
It will have a direct impact on the business models for how Satellite Operators will bring HTS to market. Check out this infographic that describes the HTS business models in more detail.
Thus far, the most common model we have seen play out with HTS is the Satellite Operator as the principle owner and operator of the platform, managing bandwidth on one or more satellites. Depending on the business model, the Satellite Operator sells a Mbps service to Service Providers or end-customers directly. Read More

Having the right amount of satellite capacity available in the right place is critical to the success of Service Providers and Satellite Operators leveraging High Throughput Satellites (HTS).
As discussed in previous blogs, I expect to see Service Providers deploy a blended portfolio of different business models. That means they will use managed services in some geographical regions, but then also deploy their own infrastructure on other satellites. At the same time we will see satellite operators coming down from space, and offering Mbps service due to the economics of multi-spot beam HTS. Service Providers will leverage these products as well, with terminals roaming from their own network infrastructure onto the satellite operator networks based on the geographical locations the services require.
Managing Bandwidth Across Multiple Spot Beams
Maintaining Service Level Agreements (SLAs) across the entire customer network requires managing the combined bandwidth from the multiple spot beams dedicated to that service as one single bandwidth pool. In traditional wide-beam satellites, a regional network was often covered by a single beam. In a multi spot-beam environment, however, covering a similar region means managing bandwidth across multiple spot beams and networks.
HTS planning issues become acute when you have mobile terminals. Imagine you want to cover a large geographic area, for example, North America; some HTS satellites need 50 spot beams to cover such an area. Now consider a service provider that offers an SLA to provide 1 Mbps to each terminal over this region; as terminals move around from beam-to-beam some spot beams could be empty, while others would have many terminals.

Axesat is a multinational company with presence in Mexico, Colombia, Chile, Ecuador, Peru, Venezuela and Central America.The service provider is targeting Mexico as its base for serving the entire Latin American market. Roughly half of its 12,000 VSATs are installed in this region, where it anticipates new opportunities across such core markets as retail, infrastructure, financial and oil and gas growing the business by 40-50%.
The iDirect Remote Commissioning Solution is based on Integrasys’ Satmotion product and allows Axesat to autonomously point and adjust its antennas, streamlining the overall commissioning of its X1, X3 and X5 remotes. This helps support the anticipated growth for Axesat, allowing it to deploy new services quicker, and get customers up-and-running on the network at an accelerated pace. Read More
VT iDirect, Inc. (iDirect), a company of Vision Technologies Systems, Inc. (VT Systems), today announced that Via Direta Telecom, a subsidiary of TV and radio broadcast group Rede Tiradentes de Telecomunicações, has selected the iDirect Evolution® platform to enable the largest, most ambitious distance-learning program ever created in Brazil. iDirect is a world leader in satellite-based IP communications technology.
Using iDirect technology, Via Direta will be able to deliver lessons from a teacher located in the city of Manaus to roughly 45,000 remote students situated along the rivers of the Amazon basin.
Limited broadband coverage in Brazil has left roughly 97 million people without access to the Internet.1 Actively exploring a solution, the Amazon State’s Secretary of Education has commissioned Rede Tiradentes to create a distance-learning program that spans Brazil.
The program will use satellite to connect roughly 45,000 students situated across hundreds of municipalities along the rivers of the Amazon basin with teachers located in Manaus, the capital city of the state of Amazonas. Via Direta will operate the hub on behalf of Rede Tiradentes. Read More

The recent IET MilSatcom conference was an excellent event, attended by most of the industry’s key players. It was an outstanding opportunity to hear the perspectives of the UK MOD and several of the industry’s satellite providers, integrators, and partners, chaired by the charismatic Gerard Donelan. What is really good about the IET MilSatcom event is that there are very few sales pitches and plenty of insight, opinion and prediction, with the odd contentious point thrown in to make for good discussions in the breaks. And during those breaks, we had some great networking opportunities. All finished off with a final putting the world to rights session in the nearest local watering hole.
As usual at such conferences it didn’t take long for some common threads to become clear. These were increased data rates, a need for flexibility and the fact that one solution cannot fit all requirements.
It was generally accepted that data requirements are growing at an ever increasing rate. There has been an explosion of applications and devices which are either producing a massive throughput increase, such as ISTAR or a large amount of devices generating burst data, such as sensors…then add Autonomous vehicles, aircraft and maritime platforms…and mobile command platforms…and cell backhaul…and BYOD…and Big Data….
These data requirements are also very hard to predict going forward. It was generally accepted that increases in demand range from 10 to 30 percent annually. The soon to be released 12th edition of the NSR Global Satellite Capacity Supply and Demand report will make for interesting reading. Read More

Scale. As Denis Sutherland, iDirect’s Director of Business Development, addressed in his most recent blog, the advent of high throughput satellite (HTS) services is challenging the entire satellite ecosystem with regards to scale.
It is a thread that I’d like to discuss as we look at how the ground infrastructure is evolving to support new HTS architectures.
HTS delivers higher aggregate throughput for the same amount of allocated frequency in orbit. A significant reason for higher throughput is frequency reuse, which is the process of using the same spectrum across multiple sites within a network resulting in a need for the ground infrastructure to enable many more carriers across a wider MHz spectrum.
Hub equipment needs to manage an increasingly diverse and integrated network portfolio that comprises of multiple satellites, frequency bands and market applications. Plus with the larger transponder sizes with HTS it requires massive scaling on the hub and line card systems.
The use of gateway beams changes where infrastructure must be located and how it will be deployed and managed. With an HTS uplink design, an operator can no longer place hubs anywhere under a beam. Instead, the entire hub infrastructure is oftentimes concentrated in fewer gateway beams scaling the network a single satellite or network operator needs to manage to new heights.
HTS throughput levels can also lead to more remotes per network and a larger overall bandwidth pool to manage, which can ultimately drive business growth for satellite operators and increase the operational complexity exponentially.
