Why do we need to take this course?
Because everything goes toward The Internet, and it starts with what you will learn in this course, like 5G, FTTH, Radio, etc.

What is Telecommunication?
• IEEE Standard Dictionary defines telecommunication as a signal transmission through specific distance. example: telegraph, radio or television.
• From etymology: – Tele = at a distance – Communication = information exchange (voice, data, video)
Telecommunication: sending information from one point to another through a specific media (cable, optic, radio)

Elements of telecommunication
Telecommunication consists of 3 elements:
1. Source (Transmitter)
2. Medium
3. Destination (Receiver)

Telecommunication Network Taxonomy
1. From service type point of view:
• Voice
– Fixed: PSTN (Public Switched Telephone Network) / ISDN (Integrated Services Digital Network)
– Mobile (wireless access): PLMN (Public land mobile network)
• Data (text, image): Internet (LAN, WAN)
• Value Added Service: IN (universal access number, premium rate service, freephone, credit call)
• Entertainment: CATV / HFC (hybrid fiber-coax)

Telecommunication Network Taxonomy
5. From direction way point of view:
• Simplex: one way (uni-directional), ex. radio, TV
• Half Duplex: two way (bi-directional) un-simultaneously, ex. CB radio
• Full Duplex: two way (bi-directional simultaneously, ex. telephone
6. From type of current point of view:
• Direct Current: Morse Code
• Alternating Current: (all type of medium can transmit this type of current) radio, cable, fiber optic

Basic Concept of Telecommunication
Transducer: type of device that can transform energy from one form to another, for example:
• Microphone: transform voice into electric wave
• Loudspeaker: transform electric wave into voice
![Page 16: Telecommunication Network The Fundamental · Telecommunication Network Taxonomy 1. From service type point of view: •Voice –Fixed: PSTN (Public Switched Telephone Network) / ISDN](https://reader030.fdocuments.in/reader030/viewer/2022040414/5f20e32e249cc51efe05b8da/html5/thumbnails/16.jpg)

Why do we need to push the boundaries of telecommunication?
Because: • Distance of the two points of telecommunication become farther
• Energy consumption for transmission become less abundant
• Everyone wants to be connected anytime anywhere anyway
• Everyone wants better service
In telecommunication research we need to emphasize on: • How do we represent information?
• How do we sent information?
• How do we restore information?

History of telecommunication network
1837: Samuel Morse exhibited a working telegraph system
1876: Alexander Graham Bell, invented the first telephone
1951: first direct long distance dialing
1962: first international satellite telephone call
1980: public service of digital networks
1983: 1G (AMPS), analog mobile phone
1991: 2G (GSM), cellular telephones has become common
1998: 3G
2008: 4G
Trend:
1. from wired to wireless,
2. from analog to digital,
3. from voice to data
