Bharti Airtel, the second-largest telecom operator in India with greater than 400 million subscribers, is deploying Free-Area Optical Communications (FSOC) expertise to deal with the restrictions of conventional fiber and microwave applied sciences, based on the newest GSMA Intelligence report. Airtel has deployed FSOC in 4 Indian states, with cell backhaul being the first use case.

Airtel Community Enlargement and Challenges
Regardless of its intensive community infrastructure throughout India, Airtel is experiencing a surge in information consumption pushed by its vital 5G rollout. This improve in demand has posed challenges in backhaul capability, which should be resolved. Conventional fiber rollouts face hurdles equivalent 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 every single place, whereas microwave has capability challenges,” the report mentioned.
Consequently, Airtel has explored various, modern options to deal with these points. To enhance its current 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 information wants.
What’s FSOC Know-how?
Free-space optical communications use gentle waves to transmit information, much like how optical fiber cables (OFC) work. Whereas fiber-optic cables depend on skinny strands of glass, FSOC transmits information via 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 power consumption, and ease of deployment.
Airtel is leveraging FSOC to deal with backhaul necessities and bridge protection gaps, notably in areas the place conventional applied sciences equivalent 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 situations various throughout states, with challenges equivalent to excessive RoW prices, monsoons limiting building home windows in Mumbai, and permission delays resulting from heavy building in densely populated areas of Kerala.
In every case, Taara’s WOC expertise acted as a workaround resolution, enabling Airtel to rapidly deploy RAN websites and broaden protection. Moreover, Airtel utilised Taara’s Hyperlink Availability Prediction Software, which makes use of multi-year climate and visibility information to mannequin WOC hyperlink availability, optimising deployment planning.
Function of FSOC in Airtel’s Community
FSOC isn’t solely addressing cell backhaul necessities however can also be being thought-about for mounted wi-fi entry (FWA) and hybrid transport options. The variety of websites that may assist FWA is commonly 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 possibility, complemented by microwave as a backup for redundancy throughout antagonistic situations.
The financial viability of FSOC is a key issue for Airtel, which evaluates the expertise’s complete 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 commonly most popular for decrease capability wants. FSOC bridges the hole, providing a steadiness between price, deployment time, and capability.

Third Various for Airtel
Presently, Airtel is deploying Taara’s WOC expertise in areas the place fiber is impractical and microwave doesn’t meet capability necessities. WOC represents a “third alternative” for Airtel, addressing situations 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 establish extra use circumstances and scale deployments throughout India.
Conclusion
Airtel has recognized segments the place FSOC can tackle community challenges and has built-in the expertise alongside fiber and microwave. Airtel will consider applied sciences equivalent to WOC from a TCO perspective and experiment with them for extra use circumstances to strengthen its community infrastructure and connectivity whereas addressing numerous challenges throughout India’s various terrains.
