Telegraphy.

Electricity completely changed communications. Once it was discovered that electric current flows along a wire, it seemed possible that it could be used for messages. As long as two places were connected by a wire electric impulses could be sent along it. It meant that people were able to send messages a long way at great speed. The new way of communication had a lot of advantages and by the end of the 19th century cables were laid all over the world.                                                                                       

Samuel Morse, one of the most famous people in communications, invented a special code, which we call now "the Morse code". He thought of using short and long electric impulses. Combining different sets of impulses he made a code for the whole alphabet, and the numbers from 0 to 9. This code, was the easiest and the fastest to transmit.

Later on the necessity aroused to increase the speed of sending messages. People decided to use the fact that current could flow one way round the circuit or the other. A new system called double current working" was worked out According to this system a dash and a dot are impulses of the same length but of different directions.

Then a machine was invented to send typewriter messages over a telegraph circuit. Such machines are called teleprinters or teletypes and use International 5-unit code instead of the Morse code. Each letter or figure is made up of five impulses of electric current, either positive or negative, all letters being the same length in time. A teleprinter has a keyboard and every- time one of the keys on the keyboard is pressed it sends the five impulses that make one letter or figure.

As most modern systems use alternating current, one line can be used to send many messages at the same time. It is possible if each message is sent out at a different frequency. This allows high-speed telegraph communication as well as transmission of written messages.

Telephone communication.

Another important kind of wired communication is telephony. It is the transmission of speech over a considerable distance by means of electric current. Telephone set includes a transmitter, and an electric network in addition to receiver.

The transmitter or microphone consists of a diaphragm, carbon chamber with carbon granules and insulating spacer and conductor. The electric current passes through the diaphragm and carbon granules. When we speak we produce sound waves which make the diaphragm vibrate. The diaphragm in its turn pushes the carbon granules which makes more or fewer contacts and decreases or increases the resistance. Thus the waves of electric current vary depending on the sounds we produce and pass along the line and finally reach the receiver. The receiver consists of electromagnet coils, a steel magnet and a diaphragm. A variable current passing through the magnet's coil makes the diaphragm vibrate. The frequency of these oscillations is the same as that of the transmitter. Therefore the receiver reproduces the same sounds as are spoken into the microphone.

The telephone was designed in 1875 by Alexander Bell, Later on the development of the telephone changed its construction, it became more complex. Auxiliary elements were used in the circuit to provide better transmission of speech. Further on the development improved the switching system. Now very complex telephone constructions are used and a new kind of telephone appeared - radiotelephone.

Satellite Telephone Communication.

The new satellite telephone systems combine some of the attributes of cellular telephone systems with those of traditional satellite communications networks. Conventional cellular telephony uses a band of radio waves with frequencies between 800 and 900 million cycles per second (megahertz). (The newer personal communications services, or PCS, operate at about twice this frequency, but both systems function in the same manner). The area to be served is divided into "cell", each with a base station and radio tower. To keep the transmit and receive signals separate, cell phones transmit to the nearest base station on one frequency and receive from it on a different frequency.

The number of subscribers to cellular services has grown so large in the U.S. and elsewhere that systems are being upgraded with digital technology. In traditional networks the speaker's voice is impressed onto the transmitted radio wave by varying the wave's frequency, a technique known as frequency modulation. The problem with this method is that the transmitted signal entirely occupies a piece of radio-frequency bandwidth, or channel, that is 30 kilohertz wide. To provide more capacity, engineers are seeking to make more efficient use of the channels. Therefore, many systems are now being modified to operate with phones in - which the speaker's voice is converted to a stream of digital bits before being transmitted. The data can then be "compressed" prior to transmission, reducing the amount of time each transmission occupies the channel, at the price of a slight loss of signal quality.

Digital transmission of voice signals is also employed in the conventional (or "public switched") telephone network but at much higher rates - 64 kilobits per second, as opposed to the eight kilobits per second typical of digital cellular systems. Digital sampling at such a high rate ensures good quality but requires even more bandwidth that transmitting the analog signal itself. S why bother to do it? Because it affords an easy method of merging many telephone calls onto a single fiber-optic cable or microwave link, as the individual data streams can be multiplexed together into one, higher-rate stream, which in turn can be merged with others into still higher-rate streams. Also, with digital signals it is easier to remedy any impairment encountered in the network, because each bit can be restored if, for example, its amplitude were corrupted in some fashion.

The local central office switches are connected together (usually via fiber-optic cables) to even larger "toll" switches that handle the long-distance calls. Calls going overseas are routed to special international switches, from which they are then carried over undersea fiber-optic cables or via satellite.

MESSAGES BY ELECTRICITY.

Electricity completely changed communications. Once it was discovered that an electric current would flow along a wire, it seemed possible that it could be used for message. As long as two places were connected by a wire electric currents could be sent along it. They could be sent with the speed of light. The question was how could electric current make words?

Real telegraphs were not possible until it was proved that electricity and magnetism were connected. It was found that a needle of a compass moved when it was put near a wire with a current flowing through it. A compass needle is a magnet. If a wire carrying a current could move it, then the wire must be a magnet too.

A lot of people began to see how electro-magnets could be used to send messages. One of the most famous people of all in communication is Samuel Morse. He invented the Morse code. This code is still used in signaling all over the world. His idea was simple. He thought of using time, sending, current along a wire for a long time or a short time. Combining different sets of these "impulses", just using the long or short, he made a code for the whole alphabet, and the numbers from 0 to 9.

The Morse code simplified sending messages. It was also very fast. With practice, the Morse code can be read at 30 words a minute or more. It became the most widely used code because it was the easiest to understand and the fastest to transmit. The telegraph meant that at last people could send messages a long way at great speed. Soon people wanted to send messages even farther.

If two places on land, say, London and Manchester could be connected by wire, why could not the lands themselves - England and America, for instance, be connected by wires under the sea? This was a question quickly answered after the telegraph was proved to work. There were some problems about this, however. The main one was insulation, which means protecting the wire so that electric current does not leak away. Dry air is a good insulator, but sea water is not. If a wire was laid under water, the current would all leak away. In any case, all the insulating substances, known up to then could be damaged by sea water. But in 1847 gutta-percha was introduced as an insulating material. Gutta-percha is a gummy substance obtained from trees, like rubber and it does not allow electricity to flow through it easily.

From equations to hardware.

Advances in VLSI technology make it possible to realize systems of very high complexity in a small volume of hardware using integration. In many application fields, it is necessary to implement certain algorithms, or even complete information processing systems, directly in silicon. Application domains which are likely to benefit are in the fields of signal processing and scientific computing, with applications to telecommunications, medical imaging, speech processing, image analysis and compression, radar and sonar, etc.

The design of an application specific architecture is a long and difficult task, which spans many different steps, ranging from functional specification, simulation, to chip partitioning design and assembly, making use of different techniques and tools.

The main goal of the design process can be started simply: to try to obtain a VLSI system which meets the performance and specification requirements of the project, at as low a cost as possible. To reach this, several major goals must be reached:

  • The system must be safe and reliable. This means that the functional behavior of the system should be correct, and if possible, proved to be correct.
  • The design time should be as short as possible. Indeed, the cost of the total system depends heavily on this parameter, not only because manpower is costly, but also since short time-to-market is a crucial factor of success especially when the technology is changing so fast.
  • The system must be efficient, i.e. optimal in hardware cost and speed. In fact, the goal is most often to reach a system which just meets some given speed requirement, while minimizing real-estate in term of silicon.

A New Wireless Paradigm.

Mobile communication and data communication are two of the fastest growing areas in the communications industry. In particular, mobile data communication, which includes wireless Internet, carries a great deal of momentum. The media is keeping a vigilant eye on the evolution of wireless data, and operators and various kinds of enterprise have put wireless datacom at the top of their strategic agendas.

Wireless data communication combines mobile communication and data communication by giving consumers easy access through mobile phones, pagers, or other wireless devices to relevant information on the Internet and intranets.

Operators see wireless data communication as an opportunity to create innovative services on top of existing networks and investments. Doing so will give them a means of differentiating themselves—for instance, to enhance their business image, reduce churn, attract new subscribers, and increase traffic volume per subscriber.

Enterprises are increasingly looking for ways of increasing employee productivity. Wireless data will enable professionals to access corporate data, such as e-mail, -production status, price lists, and other critical information for doing business while they are away from the office. Specific vertical segments, such as financial institutions, have expressed interest in wireless data as a way of distributing services. In this context, wireless data would improve their overall image and increase the availability of services through a rapidly growing low-cost distribution channel. These needs and initiatives from Ericsson and others, have created "phone browser technologies," such as the wireless application protocol, or WAP.

Telegraphy.

Electricity completely changed communications. Once it was discovered that electric current flows along a wire, it seemed possible that it could be used for messages. As long as two places were connected by a wire electric impulses could be sent along it. It meant that people were able to send messages a long way at great speed. The new way of communication had a lot of advantages and by the end of the 19th century cables were laid all over the world.

Samuel Morse, one of the most famous people in communications, invented a special code, which we call now "the Morse code". He thought of using short and long electric impulses. Combining different sets of impulses he made a code for the whole alphabet, and the numbers from 0 to 9. This code was the easiest and the fastest to transmit.

Later on the necessity aroused to increase the speed of sending messages. People decided to use the fact that current could flow one way round the circuit or the other. A new system called double current working" was worked out According to this system a dash and a dot are impulses of the same length but of different directions.

Then a machine was invented to send typewriter messages over a telegraph circuit. Such machines are called teleprinters or teletypes and use International 5-unit code instead of the Morse code. Each letter or figure is made up of five impulses of electric current, either positive or negative, all letters being the same length in time. A teleprinter has a keyboard and every- time one of the keys on the keyboard is pressed it sends the five impulses that make one letter or figure.

As most modern systems use alternating current, one line can be used to send many messages at the same time. It is possible if each message is sent out at a different frequency. This allows high-speed telegraph communication as well as transmission of written messages.
