3. 0 Generation
1. Motorola
2. Bell System
1. Push to talk Mobile
2. MobileTelephone Service (MTS)
3. Improved MobileTelephone Service (IMTS)
4. Advanced MobileTelephone Service (AMTS)

4. 1st Generation
 Sejarah
 Teknologi 1G
1. TeknologiAnalog
2. Hanya menyediakan fasilitas telepon suara/voice
3. Maksimum Speed 2,4 Kbps
4. Transmisi data pada 150 MHz
5. Baterai cepat habis dan kualitas voice buruk.
6. Dimensi handphone sangat besar

5. 2nd Generation
 Sejarah
GSM (Global System for Mobile Communication)
Arsitektur GSM

6. 2,5 Generation
 Sejarah
2,5G : General Packet Radio Service
Arsitektur GPRS

7. 2,75 Generation
 Sejarah
2,75G : EDGE (Enhanced Data rate for GSM Evolution)

8. 3rd Generation
 Terdapat dua standar 3G :
 WCDMA UMTS (Wideband CDMA, Universal MobileTelecommunication System)
 HSPA, HSPA+ (High Speed PacketAccess)

9. 3rd Generation
 WCDMA UMTS (Wideband CDMA, Universal MobileTelecommunication System)
384 Kbps for moving device
2 Mbps for non-moving device

10. 3rd Generation
 HSPA,
 HSPA+ (High Speed PacketAccess)

11. 4th Generation : Long Term Evolution (LTE)
 Sejarah
 LTE
 Wimax

12. 4th Generation : Long Term Evolution (LTE)

13. 5th Generation
 Overview
Internet of Things (IoT), Massive Sensors, Smart Cities,

14. 5th Generation
 Beam Forming  smart antena,
membentuk beam dengan kebutuhan
tertentu.
 Massive MIMO  menggunakan lebih
banyak antena baik pada pemancar dan
penerima. Massive MIMO bisa enam belas
antena sampai lebih. Semakin banyak jumlah
antena akan membuat jaringan semakin
kapabel dalam menangani lalu lintas data
 latency bisa 50% lebih singkat
 kecepatan unggah maupun unduh bisa 8 kali
lebih cepat (untuk rata-rata kecepatan
maksimal), dengan kapasitas 3 kali lebih besar.
5G using beam forming technolgy
Antena konvensional

15. 5th Generation
 5G offers a significant advancement over 4G
technology, from the air interface to the
core network.The result is a sophisticated
and complex communication system.To
help organize the capabilities, 5G has been
broken into three main use cases: Enhanced
Mobile Broadband (eMBB), Ultra-reliable
and Low-latency Communications (uRLLC)
and Massive MachineType Communications
(mMTC), or Massive IoT.As you can see
from the diagram below, there are a broad
set of technological capabilities being
addressed, from low latency to high
bandwidth and massive capacity.

17. 5th Generation
Frekuensi 5G

18. 5th Generation
MilimeterWave
Massive MIMO
Small Cell
Beamforming
NOMA
MEC

19. 5th Generation : Milimeter Wave
 Freq 1 to 6 GHz very
crowded : GPS,Wifi, 4G, 3G,
Satellite,
 30 to 300 GHz is called
milimeter wave
 24 to 100 GHz is proposed
for 5G

20. 5th Generation : Milimeter Wave
 The Advantages of
mmWave :
1. It’s new and less used
band
2. Higher freq waves carries
much more data than
lower freq
3. mmW makes it possible
to have massive MIMO
antenna

21. 5th Generation : Massive MIMO
 The higher freq  smaller
antenna dimension
 mmW makes it possible to
have a lot of Tx and Rx
installed on small cell or
panel.
5G
 One small cell can handle
many more users in the
same time

22. 5th Generation : Small Cell
 Small cell :
 mmW cover shorter distance
 Small cell station are needed to fill
in coverage gaps
 Each cell station covers a small area
 Distance : 10 – 100 m
 Macro Cell :
 Higher freq will have more collisions
with the obstacle
 They tend to lose energy more quickly

Macro Cell

23. 5th Generation : Beamforming
 Beamforming :
 More directional
 Less interference
 Less energy consumption
 Faster data rate can be achieved
 Standard antenna :
 Omnidireksional
 They tend to lose energy more
quickly
 Different user might interefe
5G

24. 5th Generation : Non-Ortogonal Multiple Access
(NOMA)
 1G to 3G :
 Multiple access based on
frequency, time and code.
 FDMA,TDMA, CDMA

25. 5th Generation : Non-Ortogonal Multiple Access
(NOMA)
 NOMA:
 To use the power level of user
devices to access the base station
 Allow different signals share the
same channel simultaneously
 4G : orthogonal
multiple access
5G
4G 5G

26. 5th Generation : Mobile Edge Computing (MEC)
 Edge Computing :
 Brings cloud computing
closer to user
 Low latency
 Cloud computing
 High latency
