Probably every Internet user already knows how the World Wide Web has grown in recent years. (Source: Bill Gates). And it continues to grow more rapidly. The increasing development of multimedia services to become the character. Marathon Capital does not necessarily agree. Practically, every major has a television or radio broadcasts to air simultaneously in the network. Using the Internet, you can watch movies, go shopping, play the stock market … In this regard, all the more acute is the question of speed access. Not every big city you can set yourself a good dedicated line, and country houses, generally a special subject.
Not to mention the fees … Operators of large cities, where there is a strong backbones, in the first all, of course, tend to saturate the market town and its suburbs (population and enterprises). Based on their reports, the situation promises to last for a long time. The fact is that in small towns, settlements and other small towns is of great importance the problem of "last mile". Still, "internetization" or village, for example, a number of nearby villages with low population density threatens costly to build and service network, and thus extremely low returns. Therefore, all the more common satellite Internet access. In this case, too, progress is not standing still. In addition to an asymmetric Internet access, which is strongly came into our life with the advent of DVB-cards, there were domestic satellite stations VSAT – satellite system terminals DirecWay.
Their cost is incomparably lower than the cost of professional workstations and is comparable to the value of a good home computer. Symmetric satellite Internet access DirecWay. What is it? It is a set of specialized services and satellite equipment, designed for professionals and home users, small Internet operators, or household networks. Differs sufficiently low rate plans, many of which are much lower tariffs for access to the Internet via leased lines in major cities. Herewith extremely high-quality services. Are rates of 150 MB / month up to unlimited, even in developed cities is still a rarity. Average connection speed is 256 kbit / s to 2 Mbit / sec. What is the fundamental difference symmetric from the asymmetric satellite access? The main difference lies in the fact that the symmetric (bidirectional) satellite access works independently from terrestrial providers. It is totally independent and mobile. You do not need a modem, leased line or mobile phone. Accordingly, you will not pay any extra money for it. Two-way satellite internet works almost anywhere in Russia, whether it be a small village or a huge metropolis. For mobile access to a homing system iNetVu. Also, the network operator be allowed to use telephones. How does it work? Roughly speaking, the information from the subscriber is sent to the satellite, then sent to the control station operator, and from there back to the satellite and then to the subscriber. Between the computer, or rather, a satellite terminal and the operator is organized direct communication channel via satellite technology, VSAT / DirecWay. It can be persistent (RAMA) or temporary (request for connection (DAMA) or frequency / time division (FDMA / TDMA), a connection is established automatically.) Type of connection depends on service plan. Satellite terminal operates autonomously and requires no maintenance by the user. What do I need? For a symmetrical Internet connection, you need to buy a satellite terminal (this is a kind of "external modem"), the antenna of the appropriate type and execute permission for the use of radio frequencies. Next, mount the antenna to aim it at the satellite and to conduct a series of papers on the organization of the channel.
