Wireless Communication
Wireless communication can be perceived as something man made, due to all the components that are need to transmit and receive one. In everyday life we use this type of communication to talk to ours friends over the phone, to send texts and to watch television. This is very common in world and was made for an easier interaction with people that were not physically in front of us. Meaning, we could communicate with people from a long distance away. We can be tracked of our every move. There are many techniques and ways wireless communication can be transmitted from one place to another.
Microwaves
The Microwaves method is great for long distance because it can carry more than one signal at once, making the transmission process much faster. Despite that, it is difficult for the signal not to fade and not arrive at the desired destination, so repeater stations are put in place. These repeater towers help the signal stay longer and reached the destination. The towers are put within a certain span, so the signals jumps from one tower to another until it arrives the the target place. On the top of the towers there are antennas that receive the microwave signals and send them to the next station. Also, the tower have to be seen by the other, considering that they travel in straight line. Meaning the towers must be uniform and align. The repeater towers are commonly found on tops of hills not on low ground.

Coaxial Cables
The technique of Coaxial Cables are usually put underground, it enables audio, images and data to be sent as pulse of electrical currents. This is done instead of using electromagnetic waves. The signals are transferred through wires that are imbedded into tubes, in order for the wire not to get damaged. In the tubes there are sections to help insulate and protect the thin wire laying in the middle of the tube. The material used for the insulating is a plastic disc. Coaxial cables can also be put under ocean floor. In 1962, Australia had it's first coaxial cables laid between the cities of Melbourne, Sydney and Canberra. Usually, the Australian cables have four to 12 tubes within the cables. Coaxial cables also use repeaters towers to make the signals move. However, the distance of the towers for coaxial tower have to be significantly closer than the microwave repeater tower, in order for the signal to be strong and not fade. The conductor wires can be used to supply link to small towns. Also, the use of these cables has allowed more tv and phone signals to be transmitted at once. This can be used in outback Australia, due to the fact it can be put underground and is good for small towns.

Optical Fibres
Between the three microwaves, coaxial cables and optical fibre , the fastest and most efficient by far is the optical fibre . This is because electrical signals for the electronic devices such as, microphones an computer are transformed into pulses of light. This can be done at a rapid speed. Later the pulses of light are converted back into their original form, electrical signal, that go through to your device. As the others two types of wireless communications use repeater towers, the optical fibre method also use them. The towers are to be set quite a distance apart, to be exact 38 -55 km apart. In 1958, the innovation of the laser came into the world. The word laser is an acronym, each other the letter standing for a word, Light Amplification by Stimulated Emission of Radiation. The light beam of a laser is of one colour and is very intense. When the laser's beam moves through the optical fibre, energy is absorbed into the glass. These optical fibres can be either laid under ground or under water. This is a cheaper and better alternative to the other forms of wireless communication. In Outback Australia, this is great since they are small and cheap when present with the other options.

Satellites
Satellites have a similar to the other wireless communication techniques, in the sense of their data transmission process. Meaning they help transmit data such as photographs and messages. Communication Satellites enable microwaves and radio waves to travel from place to place at the speed of light. In Australia, the satellites are commonly used to transmit signals from radio, televisions and phone signals to remote area. The connections are transmitted to the satellite in a geostationary orbit. Energy is needed to returned the signal, this energy is obtained through the sun. On the satellites there are solar panels which absorb the sun's energy and stores it for later use or use it straight away. This geostationary satellite is located approximately 36,000 above the equator, this satellites orbits the Earth every 24 hours. Therefore, it has to remain at the same point of the Earth at all times.

To reiterate, wireless communication is the transfer of signals from one place to another. It is very common in the world and is a great innovation. The best technique of wireless communication is optical fibres and satellites. Optical fibres because it is cheap, small and flexible and satellites due to the fact they are wide spread. The most efficient communication for the Australian Outback are optical fibres, since they can be put underground without anything interfering with the optical fibre. Microwaves and coaxial cables are also very commonly use wireless communication method. Most of the wireless communication can be put underground and use repeaters to help strengthen signals.
