Introduction
India’s telecom landscape has entered a new phase of friction as Airtel once again raises concerns over the quality of equipment supplied by Tata-owned Tejas Networks. What began as a technical disagreement has now escalated into a public confrontation, shedding light on the deeper challenges within India’s push for indigenous telecom infrastructure. At the heart of the dispute lies a fundamental question, does the nation’s shift toward homegrown technology risk compromising network quality, or is the conflict simply a result of overlapping spectrum realities and legacy deployment practices? As the voices grow louder, the tension between national policy, private-sector expectations, and technological adaptation becomes impossible to ignore.
the Original
Airtel Reiterates Quality Concerns
Airtel has doubled down on its stance, reiterating that the equipment supplied by Tata-owned Tejas Networks and deployed by BSNL is “sub-standard.” The company issued a fresh objection in a letter dated November 14, claiming the issue has damaged its Quality of Service since December of last year.
Allegations of Unresolved Interference
According to Airtel, repeated technical submissions, joint assessments, and discussions have not resulted in any corrective action from Tejas. Airtel alleges that continuous interference from Tejas-built radios used by BSNL has disrupted its own network operations.
Tejas Dismisses Airtel’s Claims
Tejas Networks rejected these accusations, arguing that its equipment meets the required technical standards. Instead, the company claims Airtel’s network sites are placed too close to BSNL towers, reducing coupling losses and causing unavoidable interference.
Government’s Indigenous Push
This technical battle is unfolding during India’s broader push toward telecom self-reliance. As part of government directives, BSNL is mandated to deploy locally developed 4G technology delivered through a consortium involving C-DoT, TCS, and Tejas Networks. This makes the conflict even more sensitive.
Airtel’s Technical Breakdown
Airtel claims the root cause lies in the non-conformance of Tejas’ radio filters. The filters were reportedly built to international standards for the 800 MHz band but do not match India’s tighter spectrum alignment. Airtel alleges Tejas radios radiate beyond permitted limits, interfering with its 900 MHz uplink.
Tejas’ Counterargument
Tejas maintains the problem stems from historical spectrum overlaps, not faulty hardware. The company says additional filtering is underway with guidance from the Department of Telecommunications and cooperation from both operators.
A Growing Symbol of a Larger Problem
The confrontation illustrates the tension between national goals of indigenous technology and the practical realities of network coexistence in a densely packed and spectrum-constrained country like India. It reveals the complexities behind deploying next-generation networks while relying on locally developed equipment in environments shaped by legacy bands and tight frequency windows.
What Undercode Say:
A Clash Between Ambition and Ground Reality
India’s telecom transformation is not just a technological shift, it is a political and economic symbol. The Airtel–Tejas confrontation reflects the weight of this ambition. On one hand, the government’s quest for domestic telecom solutions signals strategic independence. On the other hand, private operators cannot compromise on reliability in a hypercompetitive market.
The Technical Heart of the Dispute
At its core, the conflict revolves around out-of-band emissions and spectrum discipline. Airtel’s accusation focuses on improper filter design, a critical element because even minor deviations can trigger wide-ranging interference. If Airtel’s claims are accurate, this is not a minor manufacturing lapse, it suggests structural misalignment between Indian spectrum norms and equipment built to more generic international standards.
Spectrum Geography and Its Legacy
India’s unique allocation structure has always been unconventional. The 800 MHz band sits tightly alongside the 900 MHz uplink used by incumbent operators. This narrow separation leaves almost zero room for sloppy emission boundaries. Tejas may argue that the issue stems from historical overlap, yet technology deployed in India must reflect India’s constraints. Hardware that works elsewhere may not survive India’s spectrum topology without recalibration.
The Politics of Localisation
The dispute also exposes a psychological tension. Operators like Airtel have long relied on global vendors with decades of proven engineering consistency. Transitioning to indigenous solutions introduces natural friction. Any technical anomaly—however fixable—gets magnified because expectations are higher and tolerance for error is lower.
A Business Ecosystem Under Pressure
For Tejas, this dispute arrives at a delicate moment. The company stands at the center of India’s telecom self-reliance narrative. Any claim of sub-standard performance threatens not just its reputation, but also public trust in the larger domestic ecosystem. At the same time, operators must protect service quality. Network degradation translates to revenue loss, customer churn, and declining brand reliability.
The Quiet Role of BSNL
BSNL becomes an unintended catalyst. While its mandate to adopt indigenous equipment is aligned with government vision, it also means public-sector networks serve as testing grounds for technologies still maturing. If interference issues exist, Airtel bears the impact while BSNL remains shielded by policy requirements.
Cooperation vs Confrontation
Despite the escalating rhetoric, the technical problem is solvable. Additional filtering, recalibration, and site optimization can mitigate most interference issues. The real question is whether stakeholders can collaborate instead of trading public accusations. Given the density of India’s telecom environment, coexistence engineering is just as critical as standalone performance.
The Road Ahead
This conflict may become a defining moment for India’s domestic telecom gear ambitions. If Tejas resolves the issue effectively and transparently, it strengthens the narrative of local capability. If not, operators may hesitate to integrate indigenous solutions in future 5G or 6G phases. In the end, performance—not policy—is what determines long-term adoption.
Fact Checker Results
● Airtel did issue a letter accusing Tejas of sub-standard equipment.
● Tejas formally rejected the claim and blamed site proximity instead.
● Both companies have acknowledged spectrum overlap as part of the interference issue.
Prediction
India’s telecom sector will likely continue experiencing friction as indigenous vendors scale up. Tejas may release updated filters or revised hardware designs to align with India’s stricter spectrum windows. The government will push for reconciliation, since successful coexistence between telcos and domestic manufacturers is essential for the upcoming phases of 5G expansion and the early groundwork of 6G.
