Indian telecom service provider Bharti Airtel is set to launch 4G services in Kolkata this month. "It will be launched this month in Kolkata," Bharti Airtel CEO Sanjay Kapoor said when asked about launch of 4G services by the company on sidelines of GSMA event here, reports Financial Express.

However, it was not known immediately who would be the vendor for the Kolkata circle. The company had earlier appointed Nokia Siemens Networks for building and operating its 4G network in the Maharashtra circle using TD-LTE. Bharti Airtel will deploy its TD-LTE network in the 2.3 GHz frequency band allocated by the Indian government for broadband wireless access technologies. 

The company had won spectrum for Broadband Wireless Access spectrum in four telecom circles namely Kolkata, Maharashtra, Punjab and Karnataka and paid Rs 3,314.36 crore in 2010. In the same auction, Reliance Infotel had won a 20 Mhz slot pan-India BWA spectrum while Qualcomm, Tikona, Aircel and Augere also won BWA spectrum in some circles.
