Spectrum Refarming for LTE Extended to 900 MHz, to be to 2100MHz

Airtel, presently India's 2nd largest mobile operator has refarmed spectrum on 900MHz (band 8) band in Mumbai to roll out LTE900 as announced on February 15th. The LTE network of Airtel in Mumbai will get further boost as the company will install 7000 new BTS as well as 400km of fiber optic line across the metro circle. With carrier aggregation of 3CA and pre-5G massive MIMO Airtel's LTE network is capable of delivering world class services. Under Project Leap, Airtel is transforming the LTE network with massive MIMO and CA since 2018. 

Currently Airtel is working with its network partners Ericsson, Nokia, Huawei and ZTE to bring LTE900 to another 9 circles - Delhi, Karnataka, Andhra Pradesh, Kolkata, Punjab, Himachal Pradesh, North-East, Assam and Rajasthan in phased manner. It should be noted that Airtel already refarmed spectrum on 1800MHz usually used for 2G, for LTE deployment. 

That will bring Airtel's LTE network over 2300MHz, 1800MHz and 900MHz at par with Jio's LTE network. Later's LTE signal flies over 2300MHz, 1800MHz and 850MHz. Vodafone Idea will also follow the suit, as post merger they have ample of 900MHz, 1800MHz and 2100MHz spectrum. However Vodafone Idea's main LTE signals are on 1800MHz and 2300/2500MHz.
