5G network installation involves months of planning and preparation even before the first radio or antenna is connected.
The technical support for 5G concept is from massive MlMO technology. Massive MIMO technology is an upgraded version of traditional MIMO technology
The basic principle of massive MIMO technology is to achieve gain improvement in the target direction through weighted synthesis, thereby enhancing the target signal performance, reducing the gain in non-target directions, and even zeroing the interference direction.
5G does also require additional CIPRI and optical Fiber testing and installing. Latest test instruments can combine OTDR, Spectrum Analyser, Antenna analyser and 10G Testing in one box. MPO connectors and other fiber connectors could be checked by Fiber Inspection Probes to assure proper connection for fiber links.

4. What is telecommunication?
Telecommunication is the transmission of information
over a distance via electronic signals
Revolutionized the way we communicate
Allowing us to stay in touch with friends and family
Access information
Conduct business from anywhere in the world
Most common types of telecommunications:-
- Telephone
- Radio
- Internet
- Satellite communication
5. Basic elements of
telecommunication
Sender Message Medium Receiver
The sender, also
known as the
source or
transmitter,
initiates the
message to be
transmitted. This
can be a person,
computer, or any
other device that
generates the
information.
The message is
the information
or data is to be
communicated.
It can take
various forms
such as voice
signals, text,
images, or
videos.
The medium
refers to the
physical or
virtual channel
through which
the message is
transmitted. It
can be wired or
wireless system
such as optical
fibres, copper
wires, radio
waves.
The receiver,
also known as
the destination,
is the device or
individual that
receives the
transmitted
message. It
decodes the
received signal
to retrieve the
original
message.
6. Transmission Modes
When a data is transmitted from one device to another
device is known as transmission mode
Also known as communication mode
Three types of transmission modes are:
Transmission modes
Half-duplex mode Full-duplex mode
Simplex mode
7. Contd.
Simplex mode:
- Unidirectional communication
- Only one device can send information and another
receives
- Example: keyboard and traditional monitors
Half-duplex mode:
- Bidirectional communication
- Each station can both transmit and receive but not at
the same time
- Example: Walkie-talkie
8. Contd.
Full-duplex mode:
- Bidirectional communication
- Used when communication in both directions is
required all the time
- Example: Telephone Network
9. Evolution of mobile
communication
Mobile wireless communication system has gone
through several evolution stages in the past few decades
Due to huge demand for more connections worldwide,
mobile communication standards advanced rapidly to
support more users
10. First Generation mobile system(1G)
The first generation of mobile network was
deployed in Japan by Nippon Telephone and
Telegraph company (NTT) in Tokyo during 1979
In the beginning of 1980s, it gained popularity in
the US, Finland, UK and Europe
System used analogue signals
It uses Push to Talk (PTT), Improved mobile telephone
service (IMTS)
11. Contd.
Features:
- Bandwidth: 10 MHz (666 duplex channels with
bandwidth of 30 KHz)
- Technology: Analogue switching
- Modulation: Frequency Modulation (FM)
- Mode of service: voice only
- Access technique: Frequency Division Multiple
Access (FDMA)
12. Contd.
Disadvantages of 1G system :
- Poor voice quality due to interference
- Poor battery life
- Large sized mobile phones (not convenient to carry)
- Less security (calls could be decoded using an FM
demodulator)
- Limited number of users and cell coverage
- Roaming was not possible between similar systems
13. Second Generation mobile system(2G)
2G refers as the second generation which is based on
GSM.
In 1991, 2G was first launched in Finland.
Digital modulation signal was used in 2G.
Speed is 14 kbps to 64 kbps.
Technologies in 2G were Code Division Multiple
Access(CDMA),GSM,TDMA,GPRS.
14. Contd.
Features :
- It includes Digital text messages , Picture messages.
- Better quality and capacity and consumes less battery
power.
- Voice clarity, reduces noise in the line.
- Gives security and safety to the data and voice calls.
16. Contd.
GSM Architecture Consists of Four major interconnected
subsystems:
Base station Subsystem(BSS), two types:
- Base Transceiver station &
- Base station Controller
Network and Switching Subsystem(NSS), three different
Data Bases these are:-
- Home Location Register(HLR)
- Visitor Location Register (VLR)
- Authentication centre (AUC)
Mobile Station
Operation support subsystem
17. Third Generation mobile system(3G)
Also known as UMTS – Universal Mobile
Telecommunication Systems.
UMTS has the data rate of 384kbps
It support Video calling for the first time on mobile
devices
After the introduction of 3G mobile communication
system, smart phones became popular across the globe
Specific applications were developed for smart phones
which handles multimedia chat, email, video calling,
games, social media and healthcare
18. Contd.
Key features of 3G system
