Two Way Satellite Communication

Who needs it

    • Wherever it is difficult to get access to the internet because of the lack of standards connections (DSL, GSM) due to cost or time
    • When you need internet connection to a rural area or offshore platforms
    • When the goal is to get a high-speed broadband internet connection with High quality and insane stability
    • When you have your custom application that need encryption and you need to control and manage your own communication traffic flow among the branches independently from the communication service provider companies.
    • When security and data protection is highly required,
    • When a crystal, clear VOIP and Video conference are required.

Then EgyptSat satellite two way communication using VSAT (Very Small Aperture Terminal) is the answer

Which sectors

EgyptSat VSAT technology is tremendous choice for the following sectors:

    • Oil & Gas
    • Banks and ATM.
    • Journalists that need communication on the move
    • Banks in need squire VPN tunnel between his HQ servers and remote sites.
    • Offshore location where microware links can not perform.
    • International organization who want to connect their office all over the globe
    • Call centers who need squire high quality connectivity as a main or backup connection to offer jitter free VoIP.
    • Enterprises and financial organization that cannot tolerate loss of connectivity by using a redundant connection over a different path to perform their daily base communication like internet, e-mail, voice and video … etc.

 

How does it work

The communication satellites (Geo Stationary Satellite GEO) are positioned at a stationary location 36,000 KM above Earth’s equator. When there are two locations on earth thousands of kilometers away where the earth concave or obstacles and buildings in between are not allowing a light of sight between those two locations to establish a wireless connection, then the satellite will act as a repeater for the wireless connection to connect those two sites.

The high altitude of the satellite overcomes the problem of existing any obstacle between the communitarian points. More over the satellite will cover a huge area that allows a fast and easy deployment of the connection simply by pointing two VSAT devices with a send and receive antenna (usually 1.2 m diameter) at each location, which can be implemented in less than an hour, on the other had it will take several months and cost a lot to lay a fiber cable between the two location. The only drawback can be in the extra delay of the data communication due to the longer distance, where the data has to go through to reach the other point after traveling to the satellite. This will increase the delay to 255 ms in case of UDP traffic such as voice and video streaming or 510 ms for TCP application. Such delay is hardly noticeable unless the application is very sensitive to delay, then special configuration can be made for those type of application.

Different type of satellite called MEO (Medium Earth Orbit) and LEO (Low Earth orbit) are used on lower distance from the earth which keep rotating to offer satellite communication, and due to the lower distance data transfer delay is much less than GEO satellite and antennas used are much smaller, similar application are satellite phone and mobile data system using Inemrsat and Irridium network.

This simple next diagram shows how data moves through a satellite network. The orbiting satellite transmits (and receives) the information to a location on Earth called the Network Operations Center or NOC; The NOC itself is connected to the Internet (or private network).

The VSAT technology needs a box called indoor unit modem (IDU) to be installed as the final edge boundary of local network located inside the remote site. This box provides a verity of physical interfaces to be adequate connecting the user’s terrestrial devices –PCs, access points, routers, multilayer switches, voice gateways, IP phones, server farms, video conference, SCADA gateways, data center…etc.- The IDU also is linked with another outdoor kit (Dish antenna, BUC, LNB) installed outside the building.

EgyptSat entirely provide two VSAT WAN solution scenarios as following:

1. Point to point (P2P):

When stable, secure, high-speed telecommunication is the need, point-to-point connection is the best solution.

Any business operation with long-distance telecommunications needs will find Point-to-Point VSAT an attractive solution. For a corporation translates into permanent communication link with a branch office

Principally P2P is single channel per carrier (SCPC) to provide dedicated point to point IP connectivity between 2 branches independent their geographical locations on earth therefore P2P is distance independent link can be provisioned between any two sites within the satellite footprint consequently the service would be capable of span multiply countries.

P2P grants the following benefits to customer needs

        1. Instantly deployed and commissioned.
        2. Rapid response to the market needs any time anywhere any place.
        3. Immediately access any/all unified communication services –Voice, video, data, VPN, internet, IP connectivity…etc. – as per the customer needs resulting highly flexibility.
        4. It is highly reliable and availability with minimal point of failure.
        5. The traffic flow is routed and switched directly between the two sites with zero transient sites in between, which minimize the transmission and processing delay.
        6. Transparent network and all uni-cast and multicast applications.
        7. It can be configured as IP routing or remote bridging.
        8. Free of charge Voice and Video calls between the sites.

2.Point to multi point(P2MP):

When more cost-effective telecommunication is the need, point to multi point solution is the best choice. 

P2MP allows all the remote branches to communicate indirectly using a shared pool of bandwidth which optimize the provisioning cost and devices H/W needed whereas the branches are linked with the HUB station forming star topology, it acts as transient node, it act also as central node to provide the internet access and voice service to/from PSTN. This solution is right choice when customer has multi remote branches, and each branch has approximately same infrastructure and the cost is main target. P2MP grants the following benefits to customer needs

        1. It is the lowest cost in terms of provisioning and commissioning as well as bandwidth sharing.
        2. Rapid response to the market needs any time anywhere any place.
        3. Rapid response to the market needs any time anywhere any place.
        4. Very simple and very rapid installation with minimal H/W needed.
        5. Immediately access any/all unified communication services –Voice, video, data, VPN, internet, IP connectivity…etc. – as per the customer needs resulting highly flexibility.
        6. EgyptSat (VSAT service provider) owns the HUB station therefore the operation, maintenance and troubleshooting responsibility is under EgyptSat umbrella 24H/day, this is minimizing the ticket troubleshooting and facilitates monitoring the operation status and alarms.
        7. P2MP provide direct traffic flow between remote branch or indirect traffic flow between two or more remote branches via the HUB as transient node (two Satellite round trips 500 m sec).
