Investigation question: Research and write a report on how outback Australians communicate with their neighbors and the rest of the world using wireless technology like microwave and radio repeater towers, coaxial cables, optical fibres and satellite dishes.
Long distance communication is a very complex concept. Australia is covered with a network of microwave and radio repeater towers, coaxial cables, optical fibre and satellite dishes these are the four main ways that us Australians communicate with each other. Because of this network it allows us to transmit television and radio signals, telephone calls and facsimiles which is also known as fax and lastly with this network Australia is able to have computer data across our massive continent. This is how outback Australians are able to communicate with their neighbours and the rest of the world.
Television and radio signals, computer data and also telephone messages are able to be transmitter over long distances by using microwaves. Microwaves are able to carry multiple signals at the same time, but to be able to do this the repeater station needs to be used so that the signal doesn't dissolve before is reaches the targeted destination. The repeater multiple antennas. The antennas receive the microwave signals, the signals are then sent to the next station. For the signals to be sent to each other the repeater towers need to be visible to the next one because microwaves travel in straight lines, this is why most repeater towers are built on top of hills wherever is possible so that the microwaves are able to travel properly to each station.
Long distance communication can be done in a electric way using coaxial cables. Coaxial cables allow audio, images and also data to be transmitted as pulses of electric current rather than as electromagnetic waves. Coaxial cables are either buried under ground or laid on the ocean floor . The signals are carried along, directing wires inside tubes. This thin wire is held in the center of the tube by a plastic insulating disc. Most Australian coaxial cables have four all the way up to twelve tubes. The smaller conductor wires in the cable are use used to provide links to the smaller towers that are available. Coaxial cables are able to transmit multiple telephone calls and television signals now then they were able to before. The microwave system and the repeater stations is also need to be used along the coaxial cables so the signals do not fade away. The coaxial repeater stations have to be even closer rather than the microwave repeater stations.
Optical fibres can transfer various messages at once, more than coaxial cable or microwaves. Electrical signals from a microphone, television camera, computer or fax machine are converted into pulses of light. The pulses of light are produced when an electrical signal is used to turn light on and off millions of times per second. When the light pulses are received at the other end they are then converted back into an electrical signal that can be fed into the speakers, a television set, computer or even a fax machine. These messages are also able to be sent as microwaves or radio waves when and if necessary. Visible light energy is used to transmit messages over long distances. Laser produces an intense beam of light of one pure colour only. The beam travels through optical fibre, the glass absorbs some but not all energy. The light loses energy less quickly than normal light would this is due to the laser beam spreading out very little. Optical fibres can be located under ground or under water. These fibre are smaller, lighter, more flexible and also cheaper. These light pulses cannot be interfered by radio waves, there is no static.
Satellites allow radio waves and microwaves to be transmitted at the speed of light (299 792 458 m / s) . Satellites are utilised in Australia to transmit radio, television and telephone signals from cities all the way to remote areas. The signals are transmitted to a satellite in geoststationary orbit (circular geosynchronous orbit in the plane of the Earth's equator) The signals are then sent back to other parts of Australia or to other satellites which then transmit the multiple signals to other continents. The energy which is needed to amplify and re-transmit the signals is mostly provided from the sun. Solar panels on the satellite store solar energy or the energy is used straight away, the energy which is stored is stored in batteries for later use. A geostationary satellite which is an earth-orbiting satellite, placed at an altitude. This satellite orbits the earth once every 24 hours, this means that it stays at the same point on earth at all times. There are dish antennas which are aimed at a particular satellite ready to receive signals. A GPS also uses radio signals from at least four different satellites which can calculate and map your position.
In conclusion outback Australians communicate with their neighbors and the rest of the world by using wireless technology such as microwave and radio repeater towers, coaxial cables, optical fibres and satellite dishes. The best way for outback Australians to communicate with their neighbours and the rest of the world is by optical fibres. This is because optical fibre can transfer various messages at once, more than coaxial cable or microwaves. the messages are also able to be sent as microwaves or radio waves when and if necessary, so this is beneficial to the outback Australians because optical fibre are able to change the way the messages are being sent. Optical fibre can not be interfered by radio waves and also these fibres are smaller, lighter, more flexible and also cheaper to have.
