3.2. PLC
Currently there are many different types of methods of communication that are in sue for the transfer of information from Point A to Point B. Fibre optics, Ethernet cables, satellite transmission, wireless transmission etc. are some methods to do so. It is crucial for information that is being transferred daily to be easily controlled, monitored, quick and also reasonably economical. The Power line Carrier Communication is one of the technologies that fit the above criteria. This method is currently in used in KNX. It uses power line carriers in their layout as it minimising wiring in the house. More information can be found in Chapter 2, 2.2. http://www.engineersgarage.com/articles/plcc-power-line-carrier-communication http://www.eetimes.com/document.asp?doc_id=1279014
3.2.1 What is PLC?
Power Line Carrier (PLC) Communication is a technology for communication that allows data to be sent over power cables that are pre-existing. This means the power cable can be able to provide power and also transmit data to control a device. PLC Communication provides a ‘no new wire’ method as the original wires are re-used. This means that with PLC virtually all power lines can be monitored or controlled. It has become very easy to allow buildings with high speed network points to be connected with the use of the current AC power lines as a conduit for data transfer, http://www.engineersgarage.com/articles/plcc-power-line-carrier-communication http://www.eetimes.com/document.asp?doc_id=1279014

    Enclosed is a rough high-level conceptual view of the communication channels. This is very preliminary as we don't what suitable devices we can use for multiplexers, demux, and converters. The idea is to design a full-duplex serial com link between point A and B. The bandwidth is limited in the copper wiring (telephone line) probably would not go any higher than 115 kbps using a modem a constraint distance of 5 miles.

    What does it mean to live in a well lived life? Some may define it as where one’s living necessities are met. Others may put value on relationships between other sentient beings. How does such a multitude of social injustices and poor living conditions exist within a country that claims to promote equality for all people? A common expression is that America is a melting pot. In truth, America is a melting pot of discrimination and injustice. For example, African Americans, who are 13% of the population and 14% of drug users, are not only 37% of the people arrested for drugs but 56% of the people in state prisons for drug offenses. Institutional racism is a vital factor that permeates numerous injustices throughout our society. Institutional racism refers to specific policies and/or institutions which consistently result in unequal treatment for particular groups. I argue that institutional racism constitutes an injustice and through using Rawls theory, the veil of ignorance, institutional racism can be rectified.

The NEC NEAX 2000 IPS supports distributed processor architecture. This means that the processing requirements of the system are shared between more than processor. This allows for faster response times and redundant operation. If one processor fails, the other can take over. Two of the four buildings are equipped with 1 Pentium 200 MHz Processor dedicated to the inter-communications system.

    The strategy is updated annually taking in consideration both external and internal aspects and focuses on new opportunities to improve environmental performance (Qantas Sustainability Review, 2013). The main problem form Qantas is considered to be the aviation fuel, as it constitutes more than 94 per cent of the airline’s domestic carbon emissions. As a result the development of new sustainable fuel and the optimisation of fuel efficiency are seen a priority. The airline is aiming to a 1.5 per cent improvement in fuel efficiency each year until 2020. Furthermore, the company has achieved 3.2 per cent improvement in fuel efficiency and it is committed to see a 50 per cent reduction in its carbon emissions in the next 40 years through the use of new technologies and new biofuels (Qantas Sustainability Review, 2013).

  • Wireless Communication Essay

    The first big innovation in long distance information transfer came through the use of the Telegraph. The Telegraph was a device that transmitted electrical pulses along a wire. This allowed a person at one end of the wire to transfer an electrical signal from one location to another. By varying the pulse of the electrical signal, the first rudimentary messages were sent by Samuel Soemmering in 1809. “He used 35 wires with gold electrodes in water and at the receiving end 2000 feet the message was read by the amount of gas caused by electrolysis.” [4] Basically, Soemmering created pulses of electricity at one end of his wires and 2000 feet away at the end of the wire, different concentrations of gas were emitted depending on the strength/duration of the pulse he sent, a relay of information over 2000 feet through the use of electricity.
