New Delhi: The country's security agencies are concerned about Chinese telecom equipment provider ZTE managing Bharti Airtel's 4G network, Minister of State for Communications and IT Milind Deora said.

"A reference has been received from a security agency expressing that Bharti Airtel, while rolling out the 4G services, is using Time Division-Long Term Evolution (TD-LTE) technology, which has been developed by ZTE, a Chinese company," Deora said in a written reply to the Lok Sabha.

The information with regard to number of cities in the country where 4G network is managed by ZTE company, is being collected from the telecom service providers, Deora said.

India has been concerned that telecom equipment from Chinese companies may be infected with malware designed to jeopardize national security.
