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 deal with the restrictions of conventional fiber and microwave applied sciences, in response to the newest GSMA Intelligence report. Airtel has deployed FSOC in 4 Indian states, with cellular 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 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 akin 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 presents excessive capability however can’t be deployed in every single place, whereas microwave has capability challenges,” the report mentioned.
Consequently, Airtel has explored different, modern options to deal with 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 via gentle waves within the air. Utilizing beams within the unlicensed high-terahertz spectrum vary, FSOC presents a number of benefits, together with value 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 akin to fiber and microwave are constrained by prices, capability, or RoW challenges.

Collaboration with Taara
Airtel has partnered with Taara, a workforce inside Alphabet’s X moonshot division, to deploy wi-fi optical communication (WOC) merchandise in Karnataka, Maharashtra, Kerala, and Tamil Nadu. The deployment situations diverse throughout states, with challenges akin to excessive RoW prices, monsoons limiting building home windows in Mumbai, and permission delays as a consequence of heavy building in densely populated areas of Kerala.
In every case, Taara’s WOC know-how acted as a workaround answer, enabling Airtel to shortly 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.
Position of FSOC in Airtel’s Community
FSOC shouldn’t be solely addressing cellular backhaul necessities however can also be being thought-about for fastened wi-fi entry (FWA) and hybrid transport options. The variety of websites that may help FWA is usually restricted by backhaul capability. When fiber shouldn’t be possible, FSOC serves as a viable different. 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 adversarial situations.
The financial viability of FSOC is a key issue for Airtel, which evaluates the know-how’s complete value of possession (TCO) in comparison with legacy options like fiber and microwave. Whereas fiber presents the bottom value per bit for brief distances and high-capacity backhaul, microwave is usually most well-liked for decrease capability wants. FSOC bridges the hole, providing a steadiness between value, deployment time, and capability.

Third Various for Airtel
At present, 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 establish extra use circumstances and scale deployments throughout India.
Conclusion
Airtel has recognized segments the place FSOC can handle community challenges and has built-in the know-how alongside fiber and microwave. Airtel will consider applied sciences akin to WOC from a TCO perspective and experiment with them for added use circumstances to strengthen its community infrastructure and connectivity whereas addressing various challenges throughout India’s diverse terrains.
