An Essential Requirement

A key factor for business success is the ability to offer new specific and secure products and services to meet customer and partner requirements. Customers expect both their local and centralised IT applications to perform in all circumstances.

There are multiple challenges: application, network and architecture complexity, increasing dependence on IT tools, digital transformation etc.

It is vital for businesses to be able to depend on a partner who can guarantee:


  • Permanent and secure connectivity for traffic and data;
  • Seamless resiliency;
  • Maximum application performance;
  • Service continuity.

Frequently Asked Questions

What are satellite communication services used for?
For all types of usage via an IP or WAN serial connection – to provide video or voice communications, broadband data services or for geolocation.
What is a communications satellite?
A communications satellite is used to receive and transmit radio signals from space. The satellite uses reception and transmission antennas with electrical and electronic components which allow it to receive a signal from one terminal and then to transmit the same signal to another terminal.
What is a satellite Hub?
A satellite Hub (also known as a teleport) is an earth station which hosts the network equipment needed to connect various remote devices to Internet, telephone and video networks.
What is a satellite terminal?
A satellite terminal is the equipment required to receive or transmit a signal via satellite, such as a satellite telephone, radio or dish.
What does VSAT mean?
VSAT stands for Very Small Aperture Terminal – a two-way satellite ground station with a dish antenna that is smaller than 3.8 metres
How secure are satellite communications?
Satellites offer secure communications just like any other IP connections. Should enhanced security be required, complementary security equipment and encryption applications can be used to safeguard the network. Satellite networks offer secure communications which are equal to or even superior to terrestrial systems thanks to hardware encryption and which are independent of public facilities to anticipate any external intervention.
Are satellite services and equipment reliable?
Yes, wireless services provided by satellite and terminal equipment are reliable. Reliability is a crucial factor to be taken into account when using satellites as it is often the only wireless network to offer coverage in remote zones. Satellite communications operate independently from terrestrial infrastructures, so when terrestrial outages occur following natural or man-made events, satellite connections remain operational.
Are satellite services and equipment scalable?
Satellite networks can be used with different network topologies, from point-to-point connections to complex mesh architecture. Data rates and interconnections can be modified quickly and remotely in a few hours in order to meet customer requirements.
Why are satellites an essential component when designing a telecommunications network?

Wireless satellite systems enable the rapid roll out and/or restoration of communications when terrestrial infrastructures are insufficient or unreliable. CIO’s must include satellite services and networks within their communications networks and architecture as a redundancy requirement. These systems must be placed at the forefront and taken into account from the outset when designing the network. Allowing for the implementation of communications service in just a few days, satellite services prove their added-value when providing “instant infrastructures” for business, government and emergency services communications.

Why are satellites an essential component when it comes to data backup policies?
Satellite networks are capable of providing high data throughput in order to ensure the rapid restoration of damaged terrestrial facilities in addition to creating robust hybrid communications when combined with terrestrial solutions.
What is the difference between a LEO and GEO satellite?
LEO (Low Earth Orbit) satellites orbit the earth at low altitude. LEO satellites orbit at altitudes between 700 and 1000 kms, require around 100 minutes to orbit the earth and revolve around the earth around 14 times a day.

GEO (Geostationary Earth Orbit) is used for telecommunications and live television broadcasting. These satellites orbit along a circular path, within the plane of the equator and their radius is 42 164 km from the centre of the earth at an altitude of 35 786 km above the earth’s surface. From the ground, geostationary satellites appear to be stationary which is where the name comes from.

LEO satellites provide lower latency, but as they are not geostationary, they require the installation of a satellite to follow their trajectory.

What types of network architecture are available?
Network topology corresponds to physical architecture i.e.: which circuits are established with a single satellite hop. Topologies include point-to-point, star, mesh, ring or hybrid.
What is a hybrid network?
A hybrid network is an interconnection of two or more types of connectivity, for example VSAT plus terrestrial MPLS or VSAT plus an Internet access.
What are the benefits of a hybrid network?
A hybrid network allows businesses to increase the resiliency of their global network though the implementation of real alternative routes of communication with automatic switchover.

It supplies additional throughput for terrestrial links by providing a communal pool of satellite bandwidth for different agencies from a satellite network to avoid congestion when various links are overloaded.
It reduces global connectivity costs by optimising connection use between remote sites.

What does MPLS mean?
MPLS (Multi-Protocol Label Switching) is a routing technique which directs data based on short path labels via modular network architecture. A virtual private network, this infrastructure is highly secure for communication between remote sites and is therefore ideal for connecting agencies or datacentres without modifying the network core in addition to providing better monitoring of remote users within the company network.
What does network oversubscription mean?
Network oversubscription means that the bandwidth is shared between multiple users and is not dedicated.

  • An oversubscription ratio of 1:1 means that the bandwidth is guaranteed
  • An oversubscription ratio of 1:8 means that 8 users share the bandwidth

A Broadband Internet access is usually a service with non-guaranteed bandwidth whereas a dedicated Internet access (DIA) guarantees bandwidth from the customer’s facilities to the public Internet.

Is it possible to optimise a network without increasing the bandwidth?
Yes, by using deduplication, compression, caching plus protocol and application acceleration techniques. These techniques enable us to reduce the quantity of data transferred, the volume of data exchanged and the latency. They can be implemented by using solutions such as Optim-Booster on the customer’s network which Sonema can deploy and manage as an outsourced service.
What is SD-WAN?

SD-WAN stands for Software Defined Wan (WAN or Wide Area Network). There is no standard definition for SD-WAN within the industry. SD-WAN technology is used within the framework of hybrid networks (MPLS or VSAT) and uses WAN functions such as VPN, WAN optimisation, IPsec tunnel mode, hybrid WAN, deep packet inspection, rule management and analysis and assessment services. The purpose of SD-WAN is to simplify the management and operation of WAN by identification applications and dynamic path selection for traffic.

Sonema’s SD-WAN offer is an entirely managed service, backed up by stringent SLAs which allows us to improve the customer’s hybrid network performance through the use of routing, security and optimisation rules.

How does terrestrial connectivity transit between Europe and Africa?
According to Alcatel-Lucent, world leader in the production, installation and maintenance of submarine communications cables through its subsidiary Alcatel-Lucent Submarine Networks (ASN), 99% of intercontinental data traffic is sent by submarine cables. In total, there are around one million kilometres of cables under the seas according to the manufacturer. Submarine communications cables are funded by Internet giants such as Google and by consortia headed by leading telecoms groups. There are 448 cables in operation throughout the world of which over 10 transit between Africa and Europe including the ACE, Main One or SAT3 cables which serve West Africa. Submarine communications cables make landfall in cable landing points.
