3. Introduction to Current Trends in ICT Industry
⇒ Number of users are increasing at an exponential rate.
⇒ Utilization of wireless devices by per user is also increasing with rapid
rate.
⇒ Voice information has been shifted over data.
⇒ Data: Text, audio, image, video
Internet traffic

4. Continued–
⇒ Video information shares the maximum internet traffic ∼ 80%.
⇒ HD audio, video are the current data demand as per consumer
perspective.
⇒ Better link reliability makes the ICT industry more competitive
In high mobility condition
In the presence of scatterer or absence of LOS
⇒ Zero latency in end-to-end communication
Live heart surgery → Remote assistance by senior doctor to junior, etc.
⇒ Online gaming → A new business opportunity
Augmented virtual reality (AVR)

5. Introduction to IoT
Basics of Internet and its usage
⇒ Internet became the integral part of the people of 21st century.
⇒ Without internet current/future world economy will be collapsed.

6. Continued–
⇒ Consumer electronics product (mobile phone, tablets, desktop,
sensors) demands are increasing
Figure: Production in millions of unit
⇒ It is expected that nearly 50 billion ICT products will be consumed
over the globe till 2023.

7. Internet of things
⇒ The network of physical objects or things that are embedded with
sensors, software, and other technologies.
⇒ The purpose of this network for connecting and exchanging data with
other devices and systems over the Internet.

10. Core issues of ICT industry
⇒ Usable bandwidth for wired/wireless networks is very limited.
⇒ Signal processing becomes saturated under limited bandwidth offered
by sub-6 GHz band.
⇒ Very high data rate can’t be achieved in low bandwidth scenario.
⇒ In hyper dense network, interference suppression is big issue.
⇒ Transmit power reduction→ Fulfilling the green objective
Without loosing the QoS
Increasing SNR and data rate
⇒ At very high carrier frequency (let mm-Wave frequency band)
More signal attenuation
Operational cost becomes very high
⇒ Management and providing service to the huge number of devices
marginalizes the existing wireless network

11. Introduction to 5G
Key specification of 5G
1 Enhanced mobile broadband (eMBB)
mm-Wave communication → Provides ample amount of usable
bandwidth (B)
Data Rate → R = B log2 1 +
S
N
Only 1GB usable bandwidth is in the Sub-6 GHz band that limits the
overall data rate.→ 4G communication
2 Ultra reliable low latency communication (URLLC)
This feature empower the wireless network in high mobility scenario.
Ex-Bullet train, live video streaming
3 Massive machine type communication (M-mtc)
Internet of things (IoT)
Management of billions of device without loosing the QoS constraints.

12. IoT without 5G
⇒ In IoT
Multiple devices are supposed to be connected with the wired/wireless
network over the internet.
All devices are data hungry.
Based on the application specific activity done by devices their data
demands are also variable.
For basic communication between two devices
Power
Frequency⇒ Carrier frequency and usable bandwidth
Time ⇒ Latency
Signal processing for interference cancellation
Noise suppression
Functionality of these devices without 5G
Unable to handle the network congestion
Devices will be useless → Communication link will not be established
properly.

13. Empowering IoT with 5G
5G can operate sub-6 GHz and mm-Wave frequency band (24 GHz -
89 GHz)→ 5G - NR.
Application specific bandwidth availability in 5G.
Static user equipment (UE) can use the 5G-NR for enhancing the data
rate.
eMBB features of 5G supports the 3D-beamforming and massive
MIMO for enahancing the data rate and end-to-end communication in
same time-frequency slot.
More network densification compares to earlier generation
Fulfill the green objective.
Better interference suppression mechanism.
Better computational capability
