Bharti Airtel, the second-largest telecom operator in India with greater than 400 million subscribers, is deploying Free-House Optical Communications (FSOC) know-how to handle the constraints of conventional fiber and microwave applied sciences, in accordance with the most recent GSMA Intelligence report. Airtel has deployed FSOC in 4 Indian states, with cellular backhaul being the first use case.

Airtel Community Growth and Challenges
Regardless of its in depth community infrastructure throughout India, Airtel is experiencing a surge in knowledge consumption pushed by its important 5G rollout. This improve in demand has posed challenges in backhaul capability, which should be resolved. Conventional fiber rollouts face hurdles corresponding to difficult terrain in distant areas, delays in buying rights of method (RoW), and permissions from native authorities.
“Whereas fibre is more and more connecting websites and premises, most radio entry community (RAN) websites in India are linked with microwave hyperlinks. Fibre affords excessive capability however can’t be deployed in all places, whereas microwave has capability challenges,” the report stated.
Consequently, Airtel has explored various, modern options to handle these points. To enrich its present mixture of fiber and microwave applied sciences, Airtel is using rising applied sciences like FSOC and forging partnerships to broaden protection, improve capability, and meet rising knowledge wants.
What’s FSOC Know-how?
Free-space optical communications use gentle waves to transmit knowledge, much like how optical fiber cables (OFC) work. Whereas fiber-optic cables depend on skinny strands of glass, FSOC transmits knowledge by means of gentle waves within the air. Utilizing beams within the unlicensed high-terahertz spectrum vary, FSOC affords a number of benefits, together with price effectivity, low vitality consumption, and ease of deployment.
Airtel is leveraging FSOC to handle backhaul necessities and bridge protection gaps, significantly in areas the place conventional applied sciences corresponding to fiber and microwave are constrained by prices, capability, or RoW challenges.

Collaboration with Taara
Airtel has partnered with Taara, a group inside Alphabet’s X moonshot division, to deploy wi-fi optical communication (WOC) merchandise in Karnataka, Maharashtra, Kerala, and Tamil Nadu. The deployment circumstances diversified throughout states, with challenges corresponding to excessive RoW prices, monsoons limiting development home windows in Mumbai, and permission delays resulting from heavy development in densely populated areas of Kerala.
In every case, Taara’s WOC know-how acted as a workaround resolution, enabling Airtel to rapidly deploy RAN websites and broaden protection. Moreover, Airtel utilised Taara’s Hyperlink Availability Prediction Device, which makes use of multi-year climate and visibility knowledge to mannequin WOC hyperlink availability, optimising deployment planning.
Function of FSOC in Airtel’s Community
FSOC isn’t solely addressing cellular backhaul necessities however can be being thought-about for mounted wi-fi entry (FWA) and hybrid transport options. The variety of websites that may help FWA is usually restricted by backhaul capability. When fiber isn’t possible, FSOC serves as a viable various. In areas with difficult climate and visibility patterns, Airtel deploys hybrid options the place FSOC serves as the first backhaul choice, complemented by microwave as a backup for redundancy throughout antagonistic circumstances.
The financial viability of FSOC is a key issue for Airtel, which evaluates the know-how’s whole price of possession (TCO) in comparison with legacy options like fiber and microwave. Whereas fiber affords the bottom price per bit for brief distances and high-capacity backhaul, microwave is usually most popular for decrease capability wants. FSOC bridges the hole, providing a stability between price, deployment time, and capability.

Third Various for Airtel
Presently, Airtel is deploying Taara’s WOC know-how in areas the place fiber is impractical and microwave doesn’t meet capability necessities. WOC represents a “third selection” for Airtel, addressing eventualities the place the economics of fiber and microwave are much less beneficial. With developments like atmospheric sensing, movement detection, and monitoring controls, the reliability of FSOC has improved, enhancing availability and decreasing TCO. Because the TCO for WOC improves, Airtel might determine further use instances and scale deployments throughout India.
Conclusion
Airtel has recognized segments the place FSOC can tackle community challenges and has built-in the know-how alongside fiber and microwave. Airtel will consider applied sciences corresponding to WOC from a TCO perspective and experiment with them for extra use instances to strengthen its community infrastructure and connectivity whereas addressing numerous challenges throughout India’s diversified terrains.
