Satellite bandwidth is associated with satellite systems that work on a two way system. The first way is the sending of the signal and the second way is the receiving. This system involves sending and receiving a signal from a satellite that is orbiting the earth over 22,000 plus miles in the area. To help get an image of this orbiting satellite imagine traveling across the United States five and a half times.

This technology is not required for cell phones and is unique to satellite bandwidth. The primary satellite is a satellite that orbits the earth. This is known as the Geosynchronous satellite, which typically orbits the earth over the equator at approximately the same speed as the as the earth’s rotation. This means that the satellite stays in approximately the same spot over the earth throughout its entire orbit as its name implies.

This geosynchronous satellite creates a footprint onto the earth; this footprint is the coverage area of that particular satellite. As a user of satellite internet travels they may find that they need to switch satellites as they move in or out of the footprint of the particular satellites whose satellite Internet signal they are receiving.

The most modern satellites offer a bigger and bigger footprint to the point that some geosynchronous satellites footprints may cover the entire United States, Canada and Mexico making switching satellites less and less necessary, meaning that the user will receive satellite Internet signal from virtually anywhere in the country.

The satellite broadband signal that transmits from the geosynchronous satellite uses a frequency band that is of the electromagnetic spectrum. This signal band is the same frequency that radar detectors use and may in some cases cause distortion of the signal.

In order to send out the signal the geosynchronous satellite uses what is known as a transponder to pick up the signal in the electromagnetic spectrum This satellite also has a receive transponder so that the satellite Internet that picks up the signal coming from the users satellite, sending the signal back to the geosynchronous satellite.

For the satellite Internet signal to travel properly between the geosynchronous satellite and the user satellite the signal that transmits form the users dish must be precisely timed to be received by the geosynchronous satellite. To clarify this imagine a signal traveling from a users dish from Texas to two different satellites, one over Texas and another over Canada, the users signal will be received faster from the satellite over Texas than by the one over Canada, because the users location is closer to the Texas satellite geographically, therefore it is pertinent that the users satellite be set to operate with the Texas satellite to assure the fastest possible signal communication and consequently utilizing the satellite Internet to its best potential for the strongest possible satellite Internet transmission.

As the amount of time that children spend watching TV increases, so does the concern for how it affects their academic ability. Children are watching on average four hours of television a day, and extensive research is being made into the effects. Television can be a very useful academic tool, and has been used in the classroom for academic purposes since the 1970′s. The television programmes are used to assist children in various subject areas, and are used alongside other teaching materials, to give a well rounded approach to learning materials. This has proved successful as children prefer learning visually at a young age. In the past, few programmes were designed for this purpose.

Research into the effects of television on children’s behaviour and performance has been in place since the 1950′s. however, with the formation of the Action for Children’s Television society in 1970, the research has been extensive and covering a variety of areas. The importance of the content of children`s television has created governing bodies on each television network to make sure they are fulfilling their public responsibility. The research is weighted against product demand, current issues and education, and aims to make sure that all characters are good role models. This includes removing stereotyping and encouraging social tolerance.

As a result, regular television now consistently shows programmes of an educational nature. These programmes can easily be found on channels such as national geographic, discovery, and the learning channel, as well as on general stations worldwide. It was the well known children’s television programme Sesame Street that was first broadcast in 1969 that changed the face of educational TV for children. It showed that children do not only learn through informative documentary style programmes but that they learn skills by modelling positive behaviours on television.

Research has found that repetition is central to a child’s education, and this applies to educational TV viewing also. It states that reruns are useful as they create recognisable characters and situations which help children to learn about cause and effect, sequencing and also improve their understanding of people and the world around them. Children`s television programmes are repeated up to four times a year to maximise the potential, though of course, this also assists with costs.

Another useful feature of television is that it tackles difficult questions in the areas of morality and ethics. Through the medium of television, children are exposed to ideas and made aware of cultures that they can not necessarily experience for themselves. Television also assists with topics that are tricky to approach such as bereavement and bullying. As the subject is raised outside of the child’s environment, then it can be easier for them to discuss and deliberate over these subjects, particularly if they are relevant to their own experiences. Television is a popular medium of choice for conveying such ideas in classrooms around the world.
