This document provides an overview of telecom engineering, including definitions of key terms and concepts. It discusses how telecom engineering combines electrical engineering and computer science to enhance telecommunication systems. It defines a telecom equipment engineer as someone who designs infrastructure equipment like routers and switches. It also describes the basic components of a telecommunication system as the transmitter, medium, and receiver. It explains different types of communication and modulation techniques used to transmit signals over varying frequencies and mediums.
What is Telecom Engineering?
- 2. What Is Telecom Engineering Telecom Equipment Engineer Basics Of Telecommunication Types Of Communication Modulation Frequency Spectrum
- 3. Telecommunications engineering, or telecom engineering, is an engineering discipline that brings together electrical engineering with computer science to enhance telecommunication systems.The work ranges from basic circuit design to strategic mass developments. A telecommunication engineer is responsible for designing and overseeing the installation of telecommunications equipment and facilities, such as complex electronic switching systems, copper wire telephone facilities, and fiber optics. Telecommunication engineering also overlaps heavily with broadcast engineering.
- 4. A telecom equipment engineer is an electronics engineer that designs equipment such as routers, switches, multiplexers, and other specialized computer/electronics equipment designed to be used in the telecommunication network infrastructure.
- 5. A basic Telecommunication consists of three primary units that are always present in some form. 1)Transmitter 2)Medium 3)Reciever
- 6. A Transmitter is a collection of one or more electronic devices or circuits that convert the original source information to inform suitable for transmission over a particularly transmission medium.
- 7. There are two types of Medium. 1)Unguided Medium Which includes (Free Space/Air) 2)Guided Medium Which includes : Twisted Pair Fiber Obtics
- 8. A Reciever is a collection of electronic devices and ckts,that accepts the transmitted signal from the transmission medium and then converts those signals back to the original form.
- 9. There are three types 1)Simplex 2)Half Duplex 3)Full Duplex
- 10. Simplex is a one way communication. It Means that you can only either send or receive a message or input. Example: Radio,Remotes etc
- 11. Its a (Two way Communication). You can send and also receive msgs.(But one at a time) Example:Walkie Talkie
- 12. It is also a Two way communication. You can also send or receive msgs both at a time. Example: Mobile Phones etc.
- 14. Modulation is simply the process of changing one or more properties or parameters of a high frequency Analog Carrier in proportion with low frequency Information Signal(Message Signal).
- 15. There are various types of modulation,but the following two modulations are widely used. 1)A.m Modulation 2)F.m Modulation
- 16. Modulation is one of the most important aspect of Telecom Engineering.. It is necessay because if we will transfer only message signal of low frequenies,then we will have to make unpractically large anteenas,which is impossible. It consumes very less time for the trasformation of signals.
- 17. Elf 30Hz to 300Hz VF 300Hz to 3Khz VLF 3Khz to 30Khz Lf 30Khz to 300Khz MF 300Khz to 3MHz HF 3MHz to 30MHz VHF 30MHz to 300Mhz UHF 300Mhz to 3GHz SHF 3Ghz to 30Ghz Ehf 30GHz to 300GHz
- 18. It includes Ac Power Distribution signal and low Frequency Telementy Signals.
- 19. It includes fequencies generally associated with Human Speech, Standard Telephone Channels have a 3khz bandwidth
- 20. It includes the upper end of human hearing range. VLF are used for some Govt. and Military system such as Submarine Communications.
- 21. It is used primarily for Marine and Aeronotical Navigation System.
- 22. It is used For Commercial AM Broadcasting.
- 23. Mostly Two Way Radio Communication use this range. Amateur Radio and citizen Band use this frequency
- 24. It is used for Commercial FM Broadcasting and Commercial T.v Broadcasting.
- 25. It is used for T.v broadcasting,Land mobile communication and Cellular Telephones.
- 26. It includes majority of Frequency used for Microwave and Satellite radio Communication Systems.
- 27. It is seldom used for Radio Communications and it is accepted in very sophisticated expensive and specialized applications.
