1. This type of electronic equipment has to be maintained to a very high standard with rigorous checks at set intervals. Service engineers are required to maintain on-board equipment such as radio, radar, and automatic flight path plotting equipment. Air traffic control equipment is maintained on the ground.
2. This is an area where competition between companies is considerable and technology is moving very quickly. With the increasing numbers of computers used in the office, the home, and as part of industrial and communications equipment, there is a growing need for engineers to design these as well as service them. On the software side, there is always a demand for programmers to design software for business use and for leisure. Almost every large business organization, like banks and insurance companies, runs several local area networks (LANs). These require network managers and maintenance and software support.
3. The reduction in political tension in recent years has meant cuts in the defense industry. Nevertheless, many countries are still developing sophisticated defense systems both for home use and for export. These systems require not only engineers to design them, but highly - skilled operators to man them and maintain them. Thus the armed services recruit and train numbers of electronics technicians and engineers. The major fields of defense electronics are: early warning systems, e.g. radar; detection systems; ranging, using radar and computers; weapons guidance, using computers; communications.
4. This type ofelectronics started with transducers which allowed remote monitoring of processes, especially those which involved high temperatures or dangerous equipment. Further developments allowed processes in a whole range of manufacturing fields – from food and drink production to garbage recycling – to be fully automated. The development of robotics has led to widespread application in the car manufacturing in particular. Everything from assembling to spraying the completed car can now be done without human assistance. Tedious and unpleasant jobs have disappeared. Automation has led to savings for the manufacturer but has also contributed to unemployment.
5. Society expects a wide range of electronic items for entertainment. This can be gauged by sales of radio, hi-fi equipment, television sets, compact disc players, video recorders, satellite receivers, etc. Engineers and technicians are required not only to design and manufacture these, but also to maintain them.
6. People today expect to be able to get in touch with each other at any time and in any place. The transmission of speech, text, and other data by cable and radio is a growing field of employment. Cell phones are an area of recent expansion. Engineers are employed to manufacture, plan, install, commission, and maintain this equipment. National and television stations employ broadcasting and sound engineers.
7. Recent years have seen a sharp increase in equipment for patient care. This ranges from body scanners to electronic stethoscopes. While the operation of this equipment is the responsibility of doctors, engineers are required to work with experts in the design of such equipment, in the installation of larger equipment, and in maintenance. Job satisfaction in this area can be high.
