SAT Services
ANT Group offers a bidirectional satellite data transportation service for the needs of communications in locations where terrestrial lines are not available or not reliable.
The service is both upstream and downstream with IP connections on private or shared networks in or-der to monitor, control and update site equipment remotely.
Currently we providing connectivity based on a proprietary infrastructure and Teleport (Based in Sicily) owned Icarusnet, the satellite partner of ANT Group. The Icarusnet infrastructure and Teleport runs satellite networks in Europe, Middle East, Africa and Latin American Regions.
ANT Group can supply everything from simply the basic hardware and access + bandwidth all the way to managing your transmitter network completely.
Communication solution design, with close attention to integration of existing infrastructure and pre-existing technologies. Supply of all equipment and accessories, from satellite dishes with or without de-icing down to all needed brackets and supports for transmission towers.
Professional grade Installation of all devices with final test report Monitoring, maintenance, local and/or remote troubleshooting of eventual communication problems.
The technology
The VSAT (Very Small Aperture Terminal) provides value added satellite connectivity able to transport data for Internet/Intranet applications, Video and Voice over IP, and in general public or private networks as well as TV broadcasting video contents for contribution and distribution (Multicast).
Thanks to the flexibility, rapid deployment and low costs of set up and operations, the VSAT technology is used more and more in the deployment of networks for private, public/governmental, and corporate applications.
In all market sectors with crucial tasks and a highly reliable communication system is required, VSAT technology is used.
Hereafter we have some examples on the typical dedicated and shared services and what the state-of-the-art technology has developed further: Hub less and Star-Mesh topology networks.
POINT-TO-POINT LINKS (SCPC)
SCPC (Single Channel Per Carrier) is a satellite network topology which allows the connection of a specific single point to another specific single point without going through any other earth station.
Scenarios
Bulk data transfer is required, for example for data, voice and/or video transfer.
STAR NETWORKS (TDMA)
TDMA (Time Division Multiple Access) is a satellite network topology that allows the implementation of a STAR network where all the remote stations are dynamically connected (in time division) via satellite to a central hub. Two (or several) remotes can still communicate with each other but it would be via the central hub with double the round-trip delay.
Scenarios
SCADA networks with real-time low bitrate; when clients wish to share a dedicated chunk of capacity and/or when back up services for terrestrial lines are requested.
POINT TO MULTI POINT (MESH)
TDMA (Time Division Multiple Access) is a satellite network topology that allows several remote terminals to inter-communicate in a single hop and without having to pass via the central hub, reducing in half, the delay when compared to TDMA Star topology.
Scenarios
The Mesh topology is mainly used for a group of multiple VSAT remote terminals which require real time (voice and video) applications across multiple sites, and the direct connectivity without double hop and thus minimizing delay time.
MULTI-POINT WITH MULTI-POINT AND STAR
This Network topology allows all the remotes to access internet/Intranet via the main Hub (in Star topology mode) and to communicate within (or with?) each other in single hop (In mesh topology mode) without having to pass by the main Hub (and therefore with the delay of a single hop), depending on the different IP classes pre-assigned to the single sub-networks.
Scenarios
A corporate network that needs several remotes to talk to each other for internal purposes and the same remotes accessing internet via the main hub.
BACK-UP AND DISASTER RECOVERY
Any of the satellite applications can be used as a main source of communications or as a backup.
The backup can refer to a terrestrial network, wireless network or also a satellite network. The point of failure can be the single remote or even the gateway.
Scenarios
- Lack of satellite connection with backup to another satellite
- problems with either the fiber connectivity or the VPN that connects the Main Teleport to the customer HQ
- the main Teleport is having a hardware failure, and in this case the secondary teleport with a secondary dual and diverse fiber link can immediately take over and re-establish the service without continuity solution
