It has always been critical to ensure that satellite communications infrastructure remain online, and operational. High Throughput Satellites (HTS) introduce many reasons for redundancy and resiliency—five reasons, to be exact. Let’s take a look.
1) Gateway Architecture
One of the critical factors that impact satellite operators and service providers is the architecture of a high throughput satellite. Centrally located hub infrastructure accessing a gateway beam, a feeder link, leads to an increased amount of traffic generated from a single teleport, which equates to greater risk of network failure or service impact from uplink degradation. This is particularly relevant in the case of Ka-band, as its frequency has a higher susceptibility to rain fade compared to Ku-band and C-band. Since Ka-band frequencies are particularly prone to rain fade, a network must also leverage adaptive modulation techniques, such as Adaptive Coding and Modulation (ACM) and Adaptive TDMA, to achieve the maximum data throughput and optimized traffic in changing weather conditions.
In many cases satellite operators that are managing the teleport will make provision for service degradation such as for weather so severe that ACM can’t protect the link, or for a failure in the teleport. This will also drive operators to consider smarter gateway diversity, ensuring that failure in one gateway, will be backed up in a different location. This is the case with Telenor’s Thor 7, as explained here, which has two uplinks in Norway to achieve carrier-grade availability.
2) Scale of Networks
In a previous blog I considered how HTS networks will increase in scale. There will be additional network infrastructure with HTS, due to increased numbers of beams, more terminals, and higher data rates. As the networks grows the need for reliable network infrastructure increases. Read More

At the recent Counter Terror Expo (CT Expo) in London there was a lot of focus on the physical side of security, like barriers, fences, etc.; this is to be expected. Let’s face it, barriers and fences are the first things most people think of when they are trying to control access to an area.
The area that is being secured could be anything from a small perimeter of tens of metres, such as a forward operating base, all the way up to a national border spanning hundreds, maybe thousands, of kilometres.
There are obvious limitations to fences. They can be easily breached if they span across uninhabited areas. Quite often, by the time you realise they’ve been breached, the trespasser is long gone. The traditional solution to this problem is to have lookout points, or watchtowers, posted at regular intervals. These dramatically increase costs. Another solution is to have regular patrols up and down the fence. Patrols are cheaper, but less effective and over time it can be easy to avoid these patrols as they can become predictable. Any amateur that’s watched any movie that involves getting into or out of an area through some sort of fence knows to wait until the patrol has passed so they have the maximum time to breach the fence and make an escape before the breach is discovered.
One of the technologies on display at the CT Expo was a type of electronic watchtower. By installing remote sensing technology, movement or some other trigger can be used to start the transmission of live video or data to a central control point, and quick reaction forces can be used to intercept any potential intruders. These systems require the use of some form of backhaul technology to link these remote sensors to the central point, and because of the remote nature, satellite technology is the obvious solution.
