6G networks will focus on providing connectivity to a wide variety of heterogeneous devices, not just smartphones. 6G networks will be more intelligent than 5G networks, with network elements having their own processing power to handle a subset of data natively using AI/ML. 6G is expected to deliver data rates hundreds of times greater than 5G and provide capabilities like true hologram displays. Countries like South Korea, China, Finland, and US organizations have already started research on 6G technologies targeting frequencies from 95GHz to 3THz and beyond.

2. 6G: The Next Horizon
From Connected People and Things to
Connected Intelligence
• Extended reality (XR) cloud services together with haptic
feedback and holographic display are likely to become
mainstream human-centric applications.
• The exponential increase in the traffic demand per device,
together with strict latency and reliability requirements, will
become a major challenge for 6G network design

3. 6G: The Next Horizon
• For 6G, end-to-end (E2E) mobile communications systems
will be designed with optimal support for AI and ML.
• The 6G network architecture will bring "Networked AI", moving
away from today's centralized "Cloud AI“
• 6G will use not only the millimeter wave (mmWave) spectrum,
but also the THz or even visible light spectrum, potentially
using the entire spectrum for the first time in order to deliver
ultimate extreme connectivity

4. 6G: The Next Horizon
• 6G will integrate terrestrial networks and non-terrestrial
networks (NTNs) to deliver complete coverage worldwide,
connecting the unconnected
• With advances in high-resolution rendering and
wearable/flexible displays, devices will be able to render
media for 3D hologram displays. A Hologram is a next
generation media technology that can present gestures and
facial expressions by means of a holographic display.

5. 6G: The Next Horizon
• To provide hologram display as a part of real-time services,
extremely high data rate transmission, hundreds of times
greater than the current 5G system, will be essential.
• A hologram display over a mobile device (one micrometer
pixel size on a 6.7-inch display, i.e., 11.1 Giga pixel) form-
factor requires at least 0.58 Tbps. Moreover, support of a
human-sized hologram requires significantly a large number
of pixels (e.g., requiring several Tbps). The peak data rate of
5G is 20 Gbps. 5G cannot possibly support such an extremely
large volume of data as required for hologram media in real-
time.

6. 6G: The Next Horizon
• With the help of advanced sensors, AI, and communication
technologies, it will be possible to replicate physical entities,
including people, devices, objects, systems, and even places, in
a virtual world. This digital replica of a physical entity is called a
digital twin.
• A user’s interaction with a digital twin can result in actions in the
physical world.
• Again, to duplicate a 1 m x 1 m area, we need a Tera-pixel,
which requires 0.8 Tbps throughput assuming periodic
synchronization of 100 ms and a compression ratio of 1/300.

TSDSI began deliberations in this area through an introductory
workshop on “Telecom Technologies for the next Decade” on
29th January 2020. A Technical Report on “6G:Use cases,
Requirements and Enabling Technologies TSDSI TR 6017
V1.0.0
(https://members.tsdsi.in/s/AGsLX77GtkMx9Y4) has been
published by the Networks Study Group of TSDSI.

10. Telecommunications Standards
Development Society, India
TSDSI has adopted a two-pronged strategy for its “6G”
journey:
• Steer research in India to serve its 6G goals
• Continue engagement with global standard bodies for
harmonization of efforts including ITU WP 5D.

29. 6G in Nutshell
• 6G is expected to focus and provide network access to a
variety of heterogeneous devices with smart phone being one
of the supported device types.
• From a network perspective, B2B business model is expected
to emerge as the primary model unlike 5G which is still largely
based on B2C model
• Moreover, the network will not be pure data pipe, rather it will
have its own intelligence and processing power to process a
subset of the data enabled by native AI/ML support in the
networks.

30. Organisations started early
development
• South Korea Electronics and Telecommunications Research Institute: As might be
expected, South Korea is well ahead and this institute is conducting research on Terahertz band
technology for 6G. They are hoping to make 6G 100 times faster than 4G LTE and 5 times faster
than 5G networks.
• The Ministry of Industry and Information Technology, MIIT, China: With China investing
large amounts into technology, they are keen to gain a lead in 6G. Accordingly MIIT is directly
investing and monitoring the research and development process.
• The University of Oulu, Finland: This university has started a 6G research initiative known as
6Genesis. The project is expected to run for at least eight years and it will develop ideas that will
be suitable for 6G technology almost to 2040.
• USA initiatives: The USA is planning to open up 6G frequency spectrum at frequencies at
frequencies between 95 GHz and 3 THz for early research and development, although this will
require approval from the Federal Communications Commission FCC for frequencies over 95
gigahertz GHz to 3 THz.
