A Brief Overview Of How The VSAT System Works

1. A Brief Overview Of How The VSAT System Works The need to stay connected at all times in the contemporary digitalized environment is fuelling the demand for VSAT (Very Small Aperture Terminal) services. With the internet driving more traffic due to innovations in mobile services, an increasing number of people are seeking out VSAT Services with broader coverage, either for business or personal use. VSAT is a form of a satellite communication system that especially provides seamless and reliable wireless broadband connectivity to people in remote locations. Hence, the job of VSAT installer in Africa, especially in its villages, forests and desserts, is extremely important. The VSAT system works by processing signals from a box that communicates with a computer and an outdoor antenna equipped with a transceiver. The transceiver transmits or receives signals to and from a satellite transponder. The satellite subsequently processes signals from the terrestrial station computer, which essentially acts as a hub. Both of the end-users are connected to a hub station. The signal tends to go first to the hub station, and is subsequently send the data to the satellite. This, in turn, would beam the signal to another transceiver on the ground. VSAT can process voice, data and video signals. Geo-Synchronous satellites cover 30% of the earth’s surface, thereby providing connectivity anywhere in the coverage area. Usually, Ku and Ka-Band in Africa are used for providing connectivity through this system. VSAT C band can also be used when more extensive coverage is needed. People can choose to explore the web to acquire a more detailed insight of this system. VSAT System: A Popular Option For Satellite Connectivity In Africa While people living in the developed nations or large cities get to enjoy easy, seamless internet access, such a facility often becomes a luxury for many others. For the people working or living in the middle of nowhere, or even residing in the suburban parts of Africa, the options for availing internet service would be limited to dialup or satellite. Among both of these options, satellite connectivity in Africa is more common as it provides people with faster internet connectivity. The system of VSAT Internet in Africa has especially become quite popular over the years. VSAT additionally offers a number of advantages over terrestrial alternatives. For private applications, firms can have total control of their own communication system through VSAT, without any kind of dependence on other companies. Business and home users also get the chance to enjoy higher speed reception than they would have got while using ordinary telephone service or ISDN. A very small aperture terminal (VSAT) basically is a two-way ground station that transmits and receives data from satellites. Details about VSAT equipment in Africa can be easily found online or through the major internet providers present there.

2. 3 key types of Broadband Solutions Dialup modem systems have become a thing of the past as an increasing number of people are switching to broadband services. The speed of internet, as well as seamless connectivity provided by broadband is among its biggest attractions. The high bandwidth associated with the broadband facilitates fast data transfer in large volumes. Moreover, the charges involved in broadband connections are combatively much lesser than that of dial-up services. Today, multiple types of broadband solutions are available as well, among which people can choose the option that meets their specific requirements. •Cable: Cable modem service allows operators to provide broadband using the same coaxial cables that are used for TV Broadcast Services. Cable modems typically are external devices that have two connections, one to the cable wall outlet and the other to a computer. They offer transmission speeds of 1.5 mbps or more. The transmission speeds may vary depending on the type of cable modem, cable network, and traffic load. •Fiber: Fiber optic technology tends to convert electrical signals carrying data to light, and sends light through transparent glass fibers. This system has the capacity to transmit data at speeds far exceeding current DSL or cable modem speeds by tens or even hundreds of Mbps. The actual internet speed enjoyed by a person through fiber optic technology would depend on multiple factors, such as how close to their computer does the service provider brings the fiber, how the service provider configures the service, and so on. The fiber providing the broadband service can also simultaneously deliver voice (VoIP) and video services, including video-on-demand. •Satellite: Much like satellites orbiting the earth provide necessary links for telephone and television services, they also have the capacity to provide broadband connectivity. Satellite broadband is a form of wireless internet services, and is renowned for being especially useful for providing smooth connectivity in remote or sparsely populated areas. Satellite broadband through VSAT is especially popular in African regions where it is not feasible to install fiber optics or cable lines. Details about such networks, as well as VSAT Engineer in Africa can easily be found on the web. Downstream and upstream speeds for satellite broadband depends on multiple factors, such as the provider and service package purchased, the weather conditions, and the consumer’s line of sight to the orbiting satellite. Usually, a consumer can expect to enjoy a download speed of about 500 Kbps through broadband, which is several times faster than the download speed of dial-up Internet system. Further details about the systems mentioned above can be found online.
