A statement from Huawei India said Bharti Airtel had deployed more than 100 hops of the enhanced link which was based on the latest MIMO technology developed by the Chinese outfit.
The microwave link will provide capacity of 1Gbps over the 28Mhz spectrum, increasing the backhaul capacity by a factor of four.
India will hold its Mobile Congress, on the lines of the World Mobile Congress, from 14 to 16 October and reports say Bharti Airtel would showcase 5G trials with the three main providers - Huawei, Nokia and Ericsson. The three companies, along with China's ZTE Corporation, will also showcase their own solutions on their own.
The company claimed that this would cut power consumption by a fifth and reduce the tower rental fee by half, while allowing for a maximum transmission distance of up to 13km.
Earlier this month, a Reuters report said that an Australian team had been advising India about the reasons for the ban Canberra imposed on Huawei last year.
Citing The Australian and the Australian Financial Review, Reuters said a team led by Australian cyber affairs ambassador Tobias Feakin visited New Delhi in the first week of September.
The AFR was quoted as saying: "Indian officials were keen to get an understanding of how the Turnbull government arrived at the decision to ban Huawei, and multiple discussions have been held over the matter."
It was claimed that Feakin explained "in detail" why so-called high-risk vendors had been banned from bidding for supplying equipment for 5G networks in Australia.
Bharti Airtel has the largest MIMI deployment in the world, the statement said, adding that Huawei's technology had been optimised to cut the Raylegh distance of line-of-sight MIMO.
"MIMO technology achieves four times capacity with the same spectrum," the statement claimed. "In this way, telecom operators can build 5G-ready transport networks without extra spectrum investment.
"Huawei’s enhanced MIMO solution can reduce the antenna installation distance criteria, simplify MIMO deployment and reduce total cost of operation."
Huawei Microwave Product Line president Perry Yang said: "Creating value for customers with innovative technologies is the reason for Huawei microwave's existence. Huawei microwave is looking forward to joint innovation with more operators for network development."
