5G network slicing rules pit TRAI against telecom operators

The rollout of 5G network slicing in India has triggered a regulatory standoff between the Telecom Regulatory Authority of India (TRAI) and telecom operators over technical standards designed to prevent service degradation.

Network slicing allows telecommunications companies to partition their 5G infrastructure into separate virtual networks optimized for different use cases—such as critical communications, entertainment, or Internet of Things applications. TRAI has proposed safeguards including an 80 per cent Physical Resource Block (PRB) threshold to measure when networks become congested and trigger protective measures.

Telecom operators have voiced concerns that TRAI's proposed threshold is too restrictive and could artificially constrain network capacity during peak usage periods. The disagreement reflects broader industry concerns about regulatory constraints on how carriers manage their infrastructure as data demand accelerates across India.

The dispute underscores a fundamental tension in telecom regulation: balancing service quality guarantees for consumers against operational flexibility for network operators. How TRAI resolves this disagreement will shape how 5G services develop across the country and influence investment decisions by major carriers.
