MOBILE TECHNOLOGY/CELL PHONE TECHNOLOGY

Mobile communication involves transmitting voice or data using wireless radio transmission.

Mobile generations refer to change like mobile wireless communication network speed, technology, data capacity, frequency, latency etc.

6G TECHNOLOGY

• Sixth generation cellular technology, or 6G technology, uses cognitive technologies like artificial intelligence (AI) to enable communication several times quicker than the current 5G network. It would operate in uncharted radio frequencies. Hyper-connectivity, user-friendly interfaces, universal computing, multi-sensory data fusion, and accurate sensing would all be made possible by the development of 6G.

• Due to its ability to function at frequencies higher than those of 5G networks, it will have far greater capacity and less latency (delay).

• One of the main objectives of the 6G internet is to enable one-microsecond latency, or a one-microsecond communication delay.

• Compared to a millisecond throughput, or 1/1000 delay, this is 1,000 times faster.

• It seeks to exploit the terahertz frequency spectrum, which is presently underutilized.

Features and Working of 6G Technology

• Although 5G deployment is still in its early phases, work on 6G technology is already under way. It is anticipated that 6G will be much quicker and have less latency. The following are some of the key components of 6G technology:

• Terahertz frequencies: In order to enable 6G, engineers are trying to send data across hundreds of gigahertz (GHz) or terahertz (THz) waves.

• The 6G networks will employ radio waves with a wavelength of roughly one millimeter (frequency in THz).

• Because THz waves are shorter than those utilized by 5G, they can transport more data.

• Use of Artificial Intelligence: 6G networks will operate

better because of AI’s ability to control traffic and

guarantee dependable data reliability.

• Massive MIMO (Multiple-Input Multiple-Output): It is a technology that uses a lot of antennas for data transmission and receiving.

• 6G networks can incorporate a large number of devices and connections.

• Billions of sensors and actuators, among other devices, will be supported by 6G networks.

Significance of 6G Technology

• Sustainability: 6G will encourage sustainability by facilitating closed-loop control of multiple appliances and data collecting through quicker and less expensive per bit connectivity.

• Energy-efficient: 6G technology will be much more energy-efficient, turning off components and reducing capacity when demand is low.

• Secure: 6G networks are designed to tolerate interference from jammers.

India and 6G Technology

• India is getting ready for the commercial launch of 6G wireless technology, which is anticipated to happen by 2030.

• Patents for 6G: Over 127 patents for 6G technology have been granted to India by international organizations.

• Since this accomplishment, interest in India’s technological innovations has grown, with nations like the US expressing a strong desire to acquire India’s state-of-the-art 6G technology.

• India-US Pact: At the 2023 G20 Summit, India inked a deal with the US to further advanced research in the field of 6G, which gave its objectives even more momentum.

Bharat 6G Vision

• The Department of Telecommunications has established a Technology Innovation Group on 6G (TIG-6G) to create the Bharat 6G Vision, a strategy to develop 6G technology in India by 2030.

• Objective of this vision: To create and deploy 6G network technologies that provide secure, intelligent and pervasive connectivity, enabling people to live better lives.

• The International Telecommunication Union (ITU), a UN body that oversees the development of telecom standards and is in charge of managing spectrum and satellite orbit resources around the world, has accepted the 6G Vision Framework.

• India, through the Department of Telecommunications under the Ministry of Communications, has played an important role in the Framework’s development.

Challenges Related to 6G in India

• Complex Technology: The intricacy, resulting from a large number of parts and subsystems, could provide difficulties while developing and implementing 6G.

• Infrastructure: Significant infrastructure investments are needed for 6G. For instance, 6G networks will require new antenna designs and signal processing methods due to the difficulty of transmitting and receiving THz waves.

• Security Concerns: The enormous data volumes and extremely quick speeds of 6G networks may make them vulnerable to cyberattacks.

5G TECHNOLOGY

• 5G is the next-generation cellular technology that will provide faster and more reliable communication with ultra-low latency.

• Latency is a measure of delay. In a network, latency measures the time it takes for some data to get to its destination across the network.

• According to a government panel report, peak network data speeds with 5G are anticipated to be between 2 and 20 gigabits per second (Gbps). In comparison, 4G connectivity speeds in India average 6-7 megabits per second (Mbps), while in developed nations they reach up to 25 Mbps. The Third Generation Partnership Project (3GPP) defines and directs the standards for the use of 5G.

Advantages of 5G for communication sector

• In India, 5G is anticipated to have a $1 trillion overall economic impact by 2035, per a report from a panel created by the government.

• A different analysis from telecom equipment manufacturer Ericsson projects that India’s potential revenue from digitalization enabled by 5G will surpass

$27 billion by 2026.

• In addition, the Global System for Mobile Communications (GSMA) predicts that by 2025, India will have over 70 million 5G connections.

• 5G is anticipated to serve as the foundation for cutting- edge technologies like machine-to-machine (M2M) connectivity and the Internet of Things (IoT).

Limitations

• Frequency allocation: Compared to international operators, Indian operators have substantially less spectrum. Telecom businesses are uncertain about Return on Investment because to the high cost of investment.

• Network investment: There are problems with capital augmentation in the Indian telecom industry that need to be fixed.

• Lack of capital for investment: A large number of Indian operators are also burdened by debt.

• Telecom companies appear hesitant to take part in the auction, claiming that there is not enough spectrum available and that the reserve price of ₹490 crore per MHz is too high.

Way Forward

• Encourage design and manufacture of 5G technologies, products in India.

• Digital India must be compatible with 5G technologies.

• Idle spectrum must be freed up, at least till it generates significant revenues. Provide funding and incentives to regional telecom and technology companies so they

can grow internally, which will aid in the adoption of 5G

technology in the nation.

• Encourage 5G start-ups that make these design and production skills possible.

• Promote IPR generation that will back the above designs.

4G TECHNOLOGY

• 4G mobile technology provides wireless mobile broadband internet access in addition to voice and other services of 3G.

• Applications include improved web access, Internet Protocol (IP) telephony, Video Conferencing, Cloud Computing, Gaming Services, High-Definition Mobile

TV etc. 4G uses LTE (Long Term Evolution) technology, which allows voice & data-communication simultaneously
