Outlines
4. • 5G: 5th Generation mobile network
• 5G is a new global wireless standard after 1G, 2G, 3G, and 4G
networks
• 5G was commercialized in 2019
• No company or person invented or owns 5G
• There are several companies within the mobile ecosystem
that are contributing to bringing 5G to life Challenges
• 3rd Generation Partnership Project (3GPP), the industry
organization that defines the global specifications for 3G
UMTS (including HSPA), 4G LTE, and 5G technologies
Overview of 5G Technology
Introduction:
6. Technology:
• Based on OFDM (Orthogonal Frequency Division Multiplexing)
• It also uses wider bandwidth technologies such as sub-6 GHz and mmWave
Frequency Specifications:
• Can operate in both lower bands (e.g., sub-6 GHz) as well as mmWave (e.g., 24 GHz and
up)
• In India now: sub-6 GHz
• This will bring extreme capacity, multi-Gbps throughput, and low latency
Operation:
• Not only faster and better than 4G, but can be expanded to mission-critical
communications and connecting the massive IoT
What make up 5G?
3 Key Points:
7. 5G is a Unified Platform that is more capable than 4G
• Not only for Broadband Telephone but also for mission-critical communications and
connecting the massive IoT
• Supports all Spectrum types (licensed, shared, unlicensed) and bands (low, mid, high)
5G uses Spectrum Better than 4G
• Can use in bands - from low bands below 1 GHz, to mid bands from 1 GHz to 6 GHz, to high
bands known as millimeter wave (mmWave).
5G is Faster than 4G:
• Delivers up to 20 Gigabits-per-second (Gbps) peak data rates and 100+ Megabits-per-
second (Mbps) average data rates
5G has More Capacity than 4G
• Support a 100x increase in traffic capacity and network efficiency
5G has Lower Latency than 4G
• 10x decrease in end-to-end latency

9. Challenges in 5G
Frequency Bands:
• 5G NR: for sub-6 GHz and millimeter-wave range
• Design of hardware at millimeter waves are much complex than low frequency
range
• To support interoperability -> Needs multiband -> Addition of more band increases
complexity
High Data Volume:
• To support high resolution video calling, live streaming, downloading -> huge
volume data support is required
MIMO Technology:
• For High data speed -> MIMO/massive MIMO is need -> Algorithms becomes complex
Key Challenges:
10. Challenges in 5G
Beamforming:
• Complex task to locate each devices under a particular
cell
• Needs high level processing at base stations High Data
Volume:
• To support high resolution video calling, live streaming,
downloading -> huge volume data support is required
D2D Communication:
• Complex data transmission protocols required to implement this
Ultra Low Latency:
• Latency less than 1 millisecond is required - else
critical services to be affected
Security and Privacy:
• Ensuring end-to-end security and privacy among multiples
devices is challenging
Key Challenges:
11. 5G in India
Officially launched in October 2022
Players: Reliance Jio and Airtel
As of December 2022: 5G launched in 387 Districts
December 2024: Target to achieve 100% 5G coverage
Jio -> 5G standalone (SA) network, Airtel -> 5G non-standalone (NSA) network
Status of 5G in India:
