5G IN INDIA

IN NEWS:

India and the USA are having bilateral discussions over realizing a secure 5G wireless network.

WHAT IS 5G?

• 5G or fifth generation is the latest cellular communication standard for transmitting data over wireless networks. The "G" stands for "GENERATION".
• Each Generation is defined as a set of telephone network standards for the technological implementation of a particular mobile phone system. With each generation the speed and the data capacity increases and the technology used to achieve that speed changes. For eg, 1G offers 2.4 kbps, 2G offers 64 Kbps , 3G offers 144 kbps-2 mbps whereas 4G offers 100 Mbps - 1 Gbps

OPPORTUNITIES WITH 5G:

• Speed: 5G networks will be 10 times faster than existing 4G networks. Data rates of about 10 Gbps or higher can be achieved which provides the user with better experience and download and upload speeds will be higher.
• Latency: It is the delay between when a signal is sent and when it is received. This has decreased with every generation. High-speed mobile network will be equivalent to a fiber optic Internet connection accessed wirelessly.
• Internet of Things: IoT applications require an efficient network for data collection, processing, transmission, control and real-time analytics. 5G is the most efficient candidate for Internet of Things due to its flexibility, unused spectrum availability and low cost solutions for deployment. 5G systems offer the possibility of providing reliable connections to massive numbers of wireless devices simultaneously.
• Industry: 5G will help in the digitalization of industry to enable 4th industrial revolution. It will enhance automation and improve the efficiency of production processes.
• Media & Entertainment: Entertainment industry will hugely benefit from 5G wireless networks. Augmented reality and virtual reality requires HD video with low latency. 5G network is powerful enough to power AR and VR with amazing virtual experience.
• Digital inclusion: 5G network can accommodate more devices simultaneously. Only such a network can cater to the needs of a large population of India.

CHALLENGES/CONCERNS IN REALIZING 5G IN INDIA:

• Spectrum availability: Department of telecommunications (DoT) has earmarked 300 MHz in the mid-band spectrum of the 3.3-3.6 GHz range for 5G. It is argued that this 300 MHz is not enough for a large country like India. Also, the defence department and ISRO have sought 125MHz out of this 300MHz, which leaves just 175MHz for commercial telecom services.
• Spectrum pricing: The Telecom Regulatory Authority of India (Trai) has suggested a base price at Rs 492 crore per MHz. But this is up to six times higher than that of similar spectrum sold recently in countries like South Korea, Spain, Britain and Italy. Indian telecom sector is already suffering from debt crisis which prevents them from making investments for infrastructure expansion. It won’t be viable for them to shift to 5G with this pricing.
• Technology: Achieving high data rates with low latency requires a number of technical changes. India lacks the technical knowhow for the roll out of 5G. She is heavily dependent on foreign manufacturers for 5G equipment to establish networks.
• Security: India is largely dependent on China for equipment imports. However, a 2017 Chinese law makes it mandatory for Chinese companies to share data with their military. This raises fears of potential espionage. India’s data protection regime is still not mature enough to take care of data security and privacy concerns.
• Policy: Lack of a clear policy to incentivize heavy investment on 5G in India. Concern over pricing shifts the focus from long term benefits.
• Interference issues: The spectrum used by 5G will be near that of some remote sensing such as well as weather and Earth observation satellites. Interference to satellite operations impairs weather prediction performance affecting the economy and public safety
• Health concerns: 5G uses higher frequency waves than earlier mobile networks and require more transmitters than previous technologies positioned closer to ground level. So, there is a concern over increased exposure to radiations.

WAY FORWARD:

The shift from 4G to 5G is not incremental in nature, but transformational. Given what it means for the entire ecosystem, skipping it is not a choice India can afford. It is important that India make most of the opportunity and should not lag behind the rest of the world

To ensure that we need to take suitable measures like:

• The availability of affordable and adequate spectrum must be ensured. In addition to the proposed band of 300 MHz, the 26 GHz millimeter wave band spectrum can also be made available for rolling out 5G services.
• The government can reduce the reserve price keeping in mind the long term benefits with the establishment of 5G networks.
• A dedicated organization on the lines of ISRO shall be established to develop capacity in communication technologies and hardware development. This will reduce our dependency on foreign equipment which compromises our security. Simultaneously we need to build cyber security architecture to defend against any possible offensives.
• Industry is a vital link in the expansion of communication sector. They must be taken into confidence with a multi stakeholder approach by addressing their various concerns.
• Adequate scientific investigations must be carried out to rule out any adverse health impacts
