The Department of Telecommunications (DoT) is likely to issue guidelines on implementation of production-linked incentive (PLI) schemes for manufacturers in the sector and start inviting applications for the same in about a week, according to government officials. Telecom gear makers firms such as Ericsson and Nokia are keen to expand their operations in India, and global companies like Samsung, Cisco, Ciena and Foxconn have shown interest to set up manufacturing bases in the country for telecom and networking products for domestic and export markets. Telecom PLI has already been approved by the government. The DoT is ready with guidelines to implement it, application format, incentive allocation, etc. It should be published on the DoT website within a week, the official, who did not wish to be named, told PTI.
