Bharti Airtel will launch on Tuesday for the first time in the country 4G services, starting from Kolkata, offering wireless broadband services at a speed which can be 10 times higher than the present speed, an official said.
The services on offer would include those which can be intercepted by and made available in the required format to the security agencies.
Airtel had announced last week that it has roped in Chinese telecom equipment maker ZTE to plan, design, supply and deploy its BWA network in Kolkata.
The 4G service has potential to provide download speeds of around 100 Megabits per second when a user is on the move, and can go up to 1 Gigabits per second at a fixed location.
The telecom major has appointed Nokia Siemens Networks (NSN) for building and operating network in the Maharashtra circle using TD-LTE - one of the 4G technologies.
The company had won BWA spectrum in 2010 for four telecom circles - Kolkata, Maharashtra, Punjab and Karnataka and had paid Rs 3,314.36 crore.
The company was allocated 20 Mhz of BWA spectrum in 2.3 Ghz frequency band which is considered suitable for transmitting signals for operating 4G services.
