In the past decade, the communications network has experienced a huge increase. This is especially true when it comes to broadband Internet access. Connection has become an increasingly wide range of public and private sector investment in infrastructure, more and more individuals and businesses to increase bandwidth access. Some rural areas and away from the island around the world is limited to areas of slow dial or unreliable broadband connection, DSL, cable to enjoy in the past, present, and even fiber optic connections. Also use the TV and computer screens of the online media around the world in high-bandwidth real-time video and audio streams.Despite the growth of the network infrastructure in some areas, there is no wired internet, however, despite this growth in access to the Internet in many areas served basis, any no access. This is a satellite Internet access is often an effective solution because it allows access to almost any place on Earth, as long as you have the appropriate equipment, software, configuration, and with satellite ISP account. Access to the Internet via satellite is one of the most expensive way around, it is mainly in many areas, the only way around the world.Possible solutions of satellite communications in any case, the connection is from a fixed location, such as an isolated plants, mining operations, and a weather station, the Consulate General of the Government's set in this case functions as a permanent setting and installation of satellite antenna or dish calibration, in order to achieve the best connection. Another possibility is a temporary set, which is more appropriate temporary or mobile applications, such as news van. Another example is when a business user to the remote areas, you need Internet access site. Several broadband satellite systems are highly mobile business, and can be set in minutes.Service costs can vary greatly, but usually depends on many factors, such as bandwidth, are using satellite / network, the amount of data, as well as other factors. As a point of comparison, residential services in the United States to start a 512 kbps downlink speed and uplink speed of the relatively slow speed of 128 kbps connection, $ 50 per molybdenum. Business-class global services, at a cost of more than 5000 yuan per molybdenum slightly faster speed and a few gigabytes of data allowance. The price difference is larger reasons far remote areas.There are some potential problems with satellite communications and Internet access to provide access to cost in the geostationary satellites, it can be about 35,000 miles above the Earth, orbit at the same rate, which in its axis of rotation of the planet. This means that the satellite will always be more than the same area on Earth. The second type of satellite is the orbit than the geostationary orbit at different elevations, and over different regions of the earth, therefore, through its orbit. These satellites in low Earth orbit (LEO) or a medium-Earth orbit (MEO).Long way to go in terms of the distance on the ground, the signal went to-orbit satellites and ground stations. As a result, known as signal delay, making many applications such as VoIP, more difficult, if not impossible to use a satellite connection. The reason is that these applications, the constant interaction between two or more parties, unlike e-mail or browsing the web, will significantly lag. For this reason, the application is usually used by the users of satellite data transmission does not require real-time lag free connection.Although it is impossible to reduce the delay in the geostationary orbit satellites, is a low-Earth orbit (LEO) and medium-Earth orbit (MEO) satellite lag. Great things for these satellites is closer to them than those in geostationary orbit (GEO) Earth surface. Satellites in geosynchronous orbit 35,786 km above the Earth in the MEO satellite orbit altitude of 20,000 km, between 8000 km and low-Earth orbit satellites, low-earth orbit of 500 km above the Earth. Although these are a considerable distance from the earth surface, sub-geostationary orbit satellite is relatively closer; at least enough to significantly reduce the connection lag. Geostationary and low Earth orbit and medium earth orbit satellites and perhaps the best aspects of the geostationary satellites is that it can cover almost one-third of the Earth's surface. "Fixed" in geostationary may sound misleading, but it refers to the fact that, although it is a very fast moving, satellite, in the same region of the earth is still. This is because it takes a whole 24 hours to complete the orbit around the Earth, the Earth's rotation about its axis, over precisely the same rate and the equator of the satellite positioning. It may also be advantageous aspect of the satellite in geostationary orbit, since, if positioning satellite is always in the same area on the ground antenna can be fixed in a static position.Not MEO and LEO satellite coverage of geostationary satellites at any given time, for some applications it is very useful. For example, these satellites in Earth orbit under a few hours, and often used to cover the north and south polar regions GEO satellite in all services. Although a specific area, only one time window, use this type of track in a particular satellite, coverage can use satellites to maintain the same track, but the distance between us. The satellite constellation is used for multiple purposes, such as Iridium and Globalstar satellite phone service companies, especiallyCertain uses of satellite communications, and their methods in addition to business and home Internet access, satellite is used for a wide range of applications, and can vary them to send and receive data. For example, you may broadcast television networks across the country or the world to the transmission of their branches, what as a simple transfer. This is the beam transmitted to the satellite in a fixed location station, they beam down on the ground, a variety of fixed positions at other locations. This connection is one-way receiving station can not transmit data back to the sending station, at least not by the same route.For two-way communication, point-to-point duplex transmission can be used. This allows the data to send and receive the same equipment, in the same connection, so that the transmission of data is a great choice. This option can also be used for private corporate network, telephone service, content distribution and many other applications. Point-to-point multipoint transmission is a similar topology and Internet consumers in their own homes. It can also be used by the company for their company's television networks, to enable them to be able to deliver content to scatter them in many places around the country. Cell phone antennas for television stations beam real-time video and audio back to the station to use a two-way transmission, mobile satellite vehicles orbiting satellite and back down to a fixed base station.
