Tejas Says BSNL Gear Meets Standards; DoT Takes Charge of Rajasthan Interference Issue: Report

Tejas Says BSNL Gear Meets Standards, Filters Being Added: Report
Tejas Networks has reportedly rejected Bharti Airtel’s allegations that its telecom equipment deployed by Bharat Sanchar Nigam Ltd (BSNL) is causing network interference in Rajasthan. The Tata-owned firm said its telecom equipment meets all industry-required quality benchmarks and is operating without issues across more than 100,000 sites nationwide.

Cause of Interference Disputed

The company stressed that its equipment “cannot be sub-standard in only one band in one state” when it co-exists with other operators’ networks across India without interference.

“Since our equipment is co-existing with other operators’ equipment in all states across 100,000 sites, without any interference issues, it can obviously not be sub-standard in only one band in one state,” Tejas Networks told the Economic Times in a statement, according to a report dated November 27, 2025.

Airtel, in a November 14 letter, claimed that technical non-conformance in Tejas’s radio equipment and filter design was leading to interference in its network. Tejas dismissed the allegation, stating in its November 24 response that the interference was primarily due to Airtel placing its sites too close to BSNL’s towers without ensuring adequate coupling losses.

Additional Filters as Mitigation

According to the report, Tejas acknowledged that when two operators’ base stations using adjacent spectrum bands are deployed in close physical proximity with antennas facing each other, extra filtering becomes essential to mitigate adjacent-channel interference. The company said BSNL has already installed such filters at about 1,000 sites and can scale up deployments if required.

“The local gear maker, however, said if the antennae of two telcos face each other at relative proximity, additional filters need to be put up, and Bharat Sanchar Nigam Ltd (BSNL) had already implemented them at a thousand sites and more can be deployed, if required,” the report added.
