• The 5G Radio Interface Technology, called 5Gi is a locally designed telecommunication network that has been designed by IIT Hyderabad, IIT Madras and the Centre of Excellence in Wireless Technology. 
• 5Gi technology is primarily meant to enhance rural coverage. It facilitates much larger reach of the 5G towers and radio networks. Hence, it is a major breakthrough for bridging the rural-urban digital divide in 5G deployment. 

Hence option 2nd is correct.
