India’s Net Neutrality Review Follows Airtel Slicing Gap

The Department of Telecommunications has sent a formal reference to the Telecom Regulatory Authority of India asking for changes or clarifications to India’s 2018 net neutrality rules so that 5G network slicing can support specialised services. Officials say telecom operators could soon offer differentiated speeds and charge varied rates for gaming, healthcare, autonomous vehicles and smart factories, provided the open internet itself stays free of content-based preference.

The move arrives after Airtel’s commercial Priority Postpaid product, later rebranded Fast Lane, put a concrete example on the table that earlier TRAI reviews said did not yet exist.

The Reference That Reached TRAI

An official familiar with the process told The Economic Times the government wants TRAI to examine what updates the net neutrality framework needs. Current norms, adopted in 2018 after TRAI’s earlier work, require equal treatment of internet traffic by speed and latency. They ban throttling, blocking or preferential treatment of any content.

Since 5G launched in 2022 the rules have looked rigid for slicing. There are no explicit bars on the technology itself. Using it to deliver different quality of service for paying users or enterprises can still be read as preferential treatment.

The same official stressed safeguards. “The internet will remain free and paid preferential treatment to select content like to a particular website will not be allowed.” Walled-garden approaches are off the table.

That framing leaves the door open for quality tiers defined by technical need rather than by which apps ride them. It also keeps the burden on TRAI to draw the line in secondary rules rather than leave operators to self-interpret the 2018 licence conditions.

Slices Run Beside Ordinary Traffic

Network slicing lets an operator create multiple virtual networks on the same physical infrastructure. Each slice can be tuned for bandwidth, latency or reliability.

• One slice can carry ordinary browsing and video on a best-effort basis.
• Another can guarantee low latency for cloud gaming or industrial robotics.
• A third can isolate enterprise traffic with stricter security and capacity.
• Resources can shift elastically when demand moves between slices.

Normal internet traffic stays on its own slice. The technical design does not require degrading the public internet. The commercial and regulatory design decides whether that separation holds when spectrum and radio resources run short.

Elasticity is the feature operators highlight and the risk consumer groups flag. When load is light, every slice can meet its target. When a cell site saturates, the scheduler must choose. How that choice is constrained, logged and audited is exactly what the DoT reference asks TRAI to settle.

Fast Lane Forced the Clarification

Bharti Airtel launched Priority Postpaid in May 2026. The service uses 5G slicing to give postpaid customers more consistent speed and lower latency in crowded locations. Airtel said the feature is content-neutral: no app or website is favoured. Existing postpaid users received it automatically. The company later rebranded the offering Fast Lane while keeping the underlying technology.

TRAI and DoT are examining the product. Early TRAI assessments reported in June suggested it may not breach the letter of existing rules. A parliamentary standing committee on communications asked both DoT and TRAI whether priority postpaid plans could compromise net neutrality for the large prepaid base and sought comparisons with Singapore, the UK and other markets.

Reliance Jio has said service-based slicing already fits current regulations. Jio’s president Udai Kumar Srivastava pointed to fixed wireless access as a live example of resource partitioning without content discrimination. Jio has also told a parliamentary panel that slicing is a legitimate 5G capability.

Vodafone Idea earlier attacked the Airtel plans, reopening the equal-access debate. Consumer voices on X and elsewhere warned of a digital class system in which higher-paying postpaid customers get a VIP lane while prepaid users absorb congestion.

The clash itself is what moved the file. Earlier TRAI reviews had treated commercial slicing as hypothetical. A live postpaid product, a parliamentary inquiry and competing operator positions turned the gap in the 2018 rules into an active docket.

Prepaid Users Sit on the Shared Floor

India’s mobile market is still dominated by prepaid connections. When a network is lightly loaded the distinction between slices barely matters. When a site fills up, the lowest-priority slice feels the squeeze first. Capacity planning is continuous, operators say, and slices are elastic rather than hard-walled. That assurance has not yet been turned into public, auditable metrics.

The 2016 Prohibition of Discriminatory Tariffs for Data Services already blocks content-based price discrimination. The 2018 Unified Licence amendment targets discrimination, restriction or interference in the treatment of content. Neither instrument speaks clearly to permanent, commercial differentiation by subscriber class that remains content-agnostic. That is the structural gap Airtel’s product occupies.

Because prepaid users form the bulk of connections, any redistributive effect lands on the largest group first. The parliamentary standing committee’s request for comparisons and prepaid-impact analysis reflects that arithmetic. Without a published floor, elasticity remains an operator claim rather than a measurable duty.

Spectrum Limits Turn Priority Into Trade-Offs

India operates with less mid-band spectrum per operator than many peers. A parliamentary committee has noted roughly 50 MHz per operator against a global average near 100 MHz. 4G holdings sit even lower relative to international norms. An IIT Madras projection cited in legal analysis expects combined network capacity utilisation to reach about 80 percent by 2027 at 50 GB per subscriber per month. Measured 5G standalone download speeds already fell 32 percent between Q2 2023 and Q2 2024 as usage climbed.

In a spectrum-rich market a priority slice can be additive. In India’s environment it is more likely redistributive. Capacity allocated to one class comes from the common pool. Airtel has claimed non-priority traffic retains roughly 60 percent headroom. Without independent verification that figure remains a company statement.

The same tension appeared in 2020 when TRAI blocked earlier Airtel Platinum and Vodafone Idea RedX premium plans while it studied whether faster lanes degraded service for others. Slicing makes the priority harder to reverse and harder to detect in real time.

Stats snapshot

• ~50 MHz average spectrum per Indian operator versus ~100 MHz global benchmark
• 32 percent drop in 5G SA download speeds Q2 2023 to Q2 2024
• ~80 percent projected network capacity utilisation by 2027 at 50 GB monthly usage
• 2018 year DoT net neutrality principles entered licence conditions

Those four figures travel together. Half the mid-band spectrum of peer markets, rising utilisation toward 80 percent, already-visible speed decline, and a licence framework written before commercial slicing all point the same way. Priority products will compete for a constrained pool unless the non-degradation floor is written in measurable terms.

Europe and the US Already Drew Different Lines

The European Union’s Open Internet Regulation carves out specialised services that need a specific quality level the public internet cannot guarantee, provided the specialised service does not degrade internet access service. BEREC has been refining further guidance on 5G network slicing; a draft annex went to public consultation after its June 2026 board meeting. The BEREC draft guidance on 5G slicing examines how slices interact with open-internet obligations.

The United States revoked federal net neutrality rules; some states keep their own. Operators there already sell differentiated 5G experiences. The UK, Singapore, Malaysia and China also run commercial slicing for consumers and enterprises. India’s 2017 TRAI recommendations already contemplated specialised services that sit outside pure internet access service rules when a guaranteed quality cannot be delivered on a best-effort basis. The TRAI 2017 specialised services recommendations drew that line years before commercial 5G slicing arrived.

What India lacks is an updated, binding secondary instrument that translates those principles into clear floors, transparency duties and audit rights for the slicing era.

1. 2016 – Prohibition of Discriminatory Tariffs blocks content-based price discrimination.
2. 2017 – TRAI specialised services recommendations draw a line for guaranteed-quality offerings outside best-effort internet access.
3. 2018 – Net neutrality principles enter Unified Licence conditions; equal treatment by speed and latency becomes binding.
4. 2020 – TRAI blocks Airtel Platinum and Vodafone Idea RedX premium plans pending study of degradation risk.
5. 2022 – Commercial 5G launch; slicing capability arrives without matching secondary rules.
6. May 2026 – Airtel Priority Postpaid goes live; parliamentary panel seeks prepaid-impact answers within 25 days.

How Specialised Services Differ From Retail Priority

The use cases named in the DoT reference span two distinct categories. Remote healthcare, vehicle control and smart-factory links need bounded latency and reliability that best-effort internet cannot promise. Gaming boosts and postpaid Fast Lane tiers improve ordinary retail experience for a paying class of subscriber.

The 2017 TRAI recommendations already separated the first category as specialised services. They sit outside pure internet access service rules when the required quality cannot be delivered on a best-effort basis. The second category is newer in commercial form and is what Airtel’s product and the prepaid-impact debate now force into the open.

A durable framework has to keep that distinction bright. Critical verticals can justify isolation and strict parameters. Ordinary retail priority still has to prove it leaves the public slice intact. Blurring the two would let any paid tier borrow the language of specialised services without meeting the same necessity test.

What Transparency Would Need To Cover

Operators already describe slices as elastic and content-neutral. Regulators and consumer groups have asked for more than description. The missing piece is continuous, comparable evidence that the baseline holds when priority traffic peaks.

• Minimum throughput, latency and packet-loss floors stated in public terms for the non-priority slice.
• Machine-readable parameters for each commercial slice so third parties can test claims.
• Clear separation of permanent retail products from short-term traffic management.
• Independent audit rights rather than reliance on operator headroom statements alone.

Airtel’s claim that non-priority traffic retains roughly 60 percent headroom illustrates the gap. The number is specific; the verification path is not. Broadband India Forum speakers at the March TRAI event made the same point: slices must be open to all on equal terms and must not degrade the general internet, and assurances without metrics will not suffice.

TRAI Must Write the Non-Degradation Floor

The DoT reference gives TRAI room to recommend concrete changes. Legal and industry analysis points to several elements any durable framework will need.

• An independently auditable non-degradation standard so baseline users keep a defined minimum throughput, latency and packet-loss floor even when priority slices are sold.
• Application-agnostic rules: slices may differ by technical quality requirements, not by which content or apps sit on them.
• Public, machine-readable disclosure of each commercial slice’s technical parameters.
• A bright line between critical specialised services (remote surgery, vehicle control) and ordinary retail priority tiers.
• Explicit treatment of permanent commercial products versus transient traffic management.

TRAI’s own 2020 review of traffic management practices proposed that DoT keep and publish a refined list of reasonable practices. That machinery was never fully activated. The TRAI net neutrality consultation archive still holds the earlier papers that framed non-discrimination around content and internet access service.

Jio and Airtel both insist their approaches stay inside the existing envelope and improve overall efficiency. Broadband India Forum voices at a March TRAI event insisted any slice must be available to all who want it on the same terms and must not degrade the general internet. Regulators, they said, cannot rely on operator assurances alone; metrics and continuous monitoring are required.

The review will decide whether 5G slicing in India becomes a set of well-fenced specialised lanes beside a protected public internet, or a quieter reordering of who gets the first claim on scarce radio resources. TRAI’s answer will set the terms for both consumer plans and the enterprise verticals that 5G was sold on.
