Telecommunication engineers are responsible for the design and development of communication equipment and infrastructure. They are also employed in modifying and improving existing designs. The telecommunication engineer is responsible for developing equipment that makes use of the various communication technologies to improve communication for society. Telecommunications include telephones (fixed or mobile), satellite systems, television and radio networks.
Telecommunications engineers design, construct, test, operate and maintain devices that send information from one place to another
Telecommunication engineers generally work as part of a very organised and highly efficient team of specialists because the area is so diverse that specialisation is the norm
Senior engineers generally supervise teams comprising other engineers, technicians, tradespeople and workers who have on the job training.
Transmission Media: how the infomation is transmitted from one place to the other.
Transmission and receiving equipment: The machines and equipment used to convert, transmit and recieve the information
Switching and recording systems: equipment used to switch signals and record times for billing
Transmission protocols: methods of encoding and decoding information
Describe the nature and range of work of telecommunication engineers
Telecommunication engineers work on the management and development of telecommunications equipment. They oversee the manufacture and installation of broadcast, telephony, satellite and cable systems. Much of their work is carried out in office locations where work health and safety (WHS) concerns relating to the ergonomics, lighting and good housekeeping are a priority. At other times their work takes them into manufacturing industry where the hazards associated with machinery and equipment may be relevant. In this environment they have to be aware of numerous industrial hazards such as electrocution. Overseeing field installation of equipment like optical cable networks or satellite dishes may expose telecommunications engineers to danger from falling equipment, lightning strikes, electrical hazards or poor safety standards on the job site.
Is thought to provide a health risk, particulary from mobile phones. In 2011 the World Health Organisation concluded that so far, there is little evidence
High voltage currents, particularly from mains supplies, can cause death
Dangers from working at heights is a hazard in this industry
can cause problems particularly when fumes are present
danger to sight from high energy laser, microscope fragments from glass fibre can penetrate and remain in the skin casuing significant problems
Use in fibre optic splicing and termination as well as many other telecommunications operations
To embark on a tertiary course in telecommunications engineering, an HSC student should be looking at subjects such as 2 Unit Mathematics, Physics, Chemistry and Engineering Studies. There are telecommunication engineering courses at some universities e.g. The University of Sydney, The University of Technology, Sydney and The University of Newcastle. The courses are Bachelor degrees. Telecommunication engineers learn about electronics, computers and also must be familiar with networks and associated equipment. In fact, in some courses the first two years of a telecommunications engineering degree will be common with electrical and computer engineering.
Australia often looks to newer industries such as telecommunications to become a core industry. With large telecommunications companies such as Telstra, Optus and others, actively looking to expand, the future prospects for telecommunication engineers should be good. It must be remembered that with the technology and communication revolution, Australia will need trained engineers in this field to ensure it does not fall behind the rest of the developed world. The expansion of digital technology into all facets of telecommunication requires the design and redesign of equipment, hence providing new opportunities for qualified telecommunication engineers.
The infrastructure developed by telecommunication engineers is designed to provide services to the consumer that probably far exceed the needs of most people. That this technology is accepted by the community in Australia is quite clear. For example, Australia has one of the World's highest levels of mobile telephone ownership. The work of the telecommunication engineer, and the technology they develop, is not without serious community based controversy. Radiation from satellite transmitters, and mobile phones has led to community fears of tumour and cancer, particularly in children exposed to the radiation.
Communities, particularly those that are remote, now have access to fast and efficient communication systems that link people both in normal times and in times of emergencies.
Despite the major advantage of excellent communication for most, some communities may complain about:
- Unsightly mobile phone towers.
- Street communication wires both overhead and underground.
- Invasion of privacy from unsolicited emails, phone calls, faxes, hacking.
- Young people becoming preoccupied with mobile phones and internet services such as text messaging, emails, social networking sites.
- Cyber bullying.
- High cost of communication services.
- Possible harmful affects of electromagnetic radiation (EMR).
Many Telecommunication engineers become frustrated with communities that have embraced the technology but protest vehemently when necessary telecommunication infrastructure impinges on their space - the 'not in my backyard' syndrome!
Many of the technologies required for successful telecommunications are not unique to the profession. For example, the industry is heavily dependant on semiconductor technology, but the use of these semiconductors allows telecommunication engineers to create unique technologies, like digital television, FM radio and mobile telephones. All of these are pivotal to modern communication and are really the province of the telecommunication engineer. Satellite technology is almost exclusively in the realm of telecommunications. There are a huge number of communication satellites utilised by modern telecommunication systems. The use of satellites has allowed the telecommunication revolution to occur. Satellites are essential in the broadcast of world news and communication from one country to another. They are also being used with special mobile phones to ensure worldwide mobile coverage. Whilst fibre optic cable is used in applications to transmit light, such as for medical examination and to illuminate pipes for TV cameras, the great bulk of optical fibre is used to carry communications signals. It is therefore, almost unique to the profession.
Use in telecommubnications because the carrier wave is atthe frequency of light which has en enourmous data carrying capacity with low attenuation.
Also being developed for fly-by-light data tranmission in computing and in the controls for next generation aircraft
Uses radio frequency (RF) broadcasting in the micro wave end of the spectrum to transmit the signal - common applications include ground based microwave networks, cellular phone systems, satellite trandmission
Geo-stationery (or geo-syncgronous) satellites orbit about 37,200km from earth to remain in a stationery position above a target are and relay signals from one part of the world to another. Low earth orbit (LEO) asynchronous satellites orbit at around 1500km and have less delay - like having a mobile phone towers orbiting in the sky.
VoIP (voice over internet protocol) utilizes the internet to carry voice calls to any telephone worldwide
Bluetooth is an open wireless technology standard for exchanging data over short distances.

Telecommunications engineers may be managers in two senses of the word. First they may be the managers of the design process, overseeing the design and development of a project. An engineer in such a position will have other engineers working on the project, while he/she co-ordinates the teams and oversees all development. Secondly, on large projects such the establishment of a telecommunications network, or the development of a satellite system, a team structure would develop with various telecommunications engineers having various management responsibilities for completion of their own segment. They should have a logical method of dealing with problems, good problem-solving skills and good communication skills. These attributes often equip the engineer well for a move into the management team of a company.
The design, construction and maintencence of telecommunications equipement and networks requires the co-ordination and task management of a range of personnel; no single engineer can do this task.
Engineers are required to, not only manage personnel that on-site, but also to manage contractors and suppliers who are off-site, in many cases international as in the case with worldwide telecommunications
Skills required by the telecommunication engineers as managers include:
Technical knowledge
Leadership by example
Experience
Generating engineering and status reports
Approachability
Creativity, insight, innocative thought
Communications skills
Willingness to learn from expirience and further study

The telecommunications field is so diverse that many projects are continually occurring. Perhaps one of the most important projects currently underway is the mobile telephone network. It is continually expanding to cover more and more of Australia, with the aim that all areas will eventually have access to a mobile telephone service. Digital television has now replaced analogue TV in Australia, and in capital cities digital radio is offered in addition to analogue AM and FM signals. Mobile telephony has grown to allow large amounts of data transfer where once phone and SMS were the only means of mobile communication. Now modern smartphones utilise 3G or LTE networks to browse the Internet, access social media and they also use GPS for personal guidance and fitness applications.
The NBN aims to bring high speed broadband and telephone services to all Australian premises
The NBN will utilise three technologies: optical fibre, fixed wireless and satelite
By 2020, the Australian government aims to have 12% of Australian employees with teleworking arrangement with their employers.
This involves areas such as videoconferencing, use of virtual offices, uploading.downloading large data files for analysis, correction, inspection, onine teaching.
Smartphones now provide users with phone, camera, email, music, computer, PDA, radio, GPS, directory, TV, video camera, video game, photo album, voice recording, watch, alarm, stopwatch, calculator, answer machine, internet - with much more to come!
Smart digital television: Enhanced picture and soudn quality, multi-view services (program guides, data casting, web browsing etc), high definition, additional free to air channels, less interference
Digital Radio: Enhanced sound quality, less interference, data such as song names can be displayed, a single digital frequency can have multiple audio lines
