Passive Infrastructure Sharing Concerns

1. Introduction

Passive infrastructure sharing refers to arrangements under which competing telecommunications operators share physical infrastructure rather than independently constructing duplicate facilities. Typical shared infrastructure includes:

• Telecom towers and masts
• Tower sites and shelters
• Power supply and backup systems
• Batteries, generators and air-conditioning
• Ducts and conduits
• Dark fibre and backhaul facilities
• Rights of way
• Civil infrastructure
• In some arrangements, antennas and transmission links

Passive sharing is generally viewed as capable of producing substantial efficiencies because operators can reduce capital expenditure, accelerate network rollout, improve geographical coverage and avoid unnecessary duplication. Indian telecom practice expressly recognises sharing of passive infrastructure, while EU competition guidance similarly treats passive sharing as generally less problematic than deeper forms of active or spectrum sharing.

The competition-law concern arises when infrastructure sharing changes from a cost-saving mechanism into a means of restricting competition—for example, through refusal of access, discriminatory access, excessive charges, exclusionary contractual conditions, exchange of commercially sensitive information, or coordination between competitors.

2. Meaning and Nature of Passive Infrastructure Sharing

Telecommunications infrastructure can broadly be divided into:

A. Active infrastructure

This includes:

• Spectrum
• Switches
• Radio-access equipment
• Base-station equipment
• Network controllers
• Other electronic transmission equipment

B. Passive infrastructure

This includes:

• Towers
• Masts
• Shelters
• Power systems
• Batteries
• Generators
• Air-conditioning
• Civil works
• Ducts
• Certain fibre and backhaul facilities.

The distinction is important because passive sharing ordinarily involves a lower degree of competitive integration than sharing spectrum, RAN equipment or commercially sensitive network strategies. The CCI has expressly treated active and passive infrastructure as distinct but complementary products.

3. Why Infrastructure Sharing Can Raise Competition Concerns

Passive infrastructure sharing can affect competition at several levels.

3.1 Reduction of infrastructure competition

If two competing operators share almost all important infrastructure, they may have fewer incentives to independently:

• construct new sites;
• improve coverage;
• increase capacity;
• invest in rural networks;
• introduce technically superior infrastructure.

EU guidance recognises that infrastructure-sharing arrangements can reduce infrastructure competition and thereby affect wholesale and retail competition.

3.2 Refusal of access

A tower company or infrastructure owner may control strategically important sites.

If competitors cannot economically duplicate those sites, refusal to provide access can become an important competition issue.

Relevant questions include:

1. Is the infrastructure indispensable?
2. Is there a realistic alternative?
3. Is the owner dominant?
4. Is access technically feasible?
5. Is the refusal objectively justified?
6. Does the refusal exclude or disadvantage competitors?

4. Relevant Competition-Law Framework in India

The principal provisions are contained in the Competition Act, 2002.

Section 3

Section 3 addresses agreements that cause or are likely to cause an appreciable adverse effect on competition.

Infrastructure-sharing agreements between competing telecom operators may therefore require assessment where they involve:

• market allocation;
• output or investment restrictions;
• price coordination;
• customer allocation;
• commercially sensitive information exchange;
• restrictions on independent network deployment.

However, ordinary passive sharing does not automatically constitute an anti-competitive agreement.

Section 4

Section 4 prohibits abuse of dominant position.

Potential abuses include:

• unfair or discriminatory conditions;
• discriminatory access;
• denial of market access;
• exclusionary conduct;
• leveraging dominance into related markets.

This is particularly relevant where a tower company controls a large proportion of strategically important infrastructure.

5. Main Competition Concerns

A. Refusal to provide access

A dominant infrastructure provider may refuse to provide access to competitors.

The competition concern is strongest where:

• infrastructure cannot readily be replicated;
• the provider controls a large proportion of relevant sites;
• access is technically feasible;
• the refusal is discriminatory;
• the refusal prevents network expansion.

The BSNL v. Indus Towers matter is particularly relevant because the CCI examined allegations concerning denial of access to passive telecom infrastructure in the Kolkata Circle.

B. Discriminatory access

An infrastructure provider may give:

• better sites to affiliated operators;
• faster installation to selected operators;
• preferential maintenance;
• better technical conditions;
• lower prices to affiliated companies.

Such conduct can raise Section 4 concerns if the infrastructure provider is dominant.

The assessment should distinguish legitimate commercial differentiation from discrimination that harms competition.

C. Excessive or discriminatory pricing

A dominant tower operator could theoretically impose:

• excessive access charges;
• discriminatory rental rates;
• discriminatory energy charges;
• excessive modification fees;
• punitive restoration charges.

The relevant question is whether pricing reflects legitimate cost and commercial considerations or constitutes exclusionary or discriminatory conduct.

D. Exclusivity

An infrastructure provider may require an operator to:

• use only its towers;
• refrain from contracting with competing tower companies;
• maintain minimum tenancy commitments;
• pay termination or exit charges;
• accept long lock-in periods.

Such provisions may reduce the ability of infrastructure providers to compete for customers and may increase switching costs.

E. Information exchange

Infrastructure sharing requires some information exchange.

For example:

• technical specifications;
• site requirements;
• installation schedules;
• capacity requirements;
• maintenance information.

But competing operators should not unnecessarily exchange:

• future pricing strategies;
• customer strategies;
• commercial rollout plans;
• marketing strategies;
• competitively sensitive investment plans.

The EU Commission specifically recognises that information exchange must generally remain limited to information necessary for the infrastructure-sharing arrangement to function.

6. Six Important Case Laws / Decisions

1. T-Mobile Deutschland GmbH / O2 Germany — Network Sharing Rahmenvertrag, Case COMP/38.369 (European Commission, 2003)

This is one of the leading decisions concerning mobile network sharing.

T-Mobile and O2 Germany agreed upon extensive cooperation involving:

• site sharing;
• infrastructure sharing;
• possible RAN sharing;
• national roaming.

The Commission distinguished different forms of cooperation because they could have different competitive effects.

The Commission concluded that the site-sharing provisions did not warrant action under Article 81(1) EC, while imposing a more careful framework around roaming. The decision recognised that extensive cooperation between competitors in a concentrated market could reduce network competition.

Principle

Passive site sharing is not automatically anti-competitive, but its effect must be examined in the context of market structure, the extent of cooperation and the parties' continuing ability to compete independently.

2. T-Mobile Deutschland / O2 Germany — Case T-328/03, General Court

The General Court considered the Commission's treatment of the T-Mobile/O2 network-sharing arrangement.

The case is important because it confirms the need to distinguish:

• site sharing;
• RAN sharing;
• national roaming;
• downstream retail effects.

The Commission had recognised that site sharing and roaming could affect different markets and therefore required separate analysis.

Principle

The competition analysis of infrastructure sharing must be sufficiently granular; different components of a network-sharing agreement cannot simply be treated as one undifferentiated arrangement.

3. BSNL v. Indus Towers Ltd., CCI Case No. 10 of 2018

This is particularly significant for Indian competition law.

BSNL alleged that Indus Towers denied or restricted access to passive infrastructure sites despite an Infrastructure Sharing Agreement.

The CCI considered the relevant market to be:

market for provision of passive infrastructure services to telecom service providers in the Kolkata Circle.

The CCI treated passive infrastructure as separate from active infrastructure and examined whether Indus Towers possessed a dominant position. The information before the Commission indicated a substantial share of infrastructure sites in Kolkata.

The Commission ultimately did not find a Section 4 contravention on the material before it, including unresolved contractual and procedural issues relating to site requests and billing.

Principle

Control over passive infrastructure can be relevant to dominance, but an allegation of denial of access must be supported by evidence showing actual exclusionary or discriminatory conduct.

4. Vodafone India / Idea Cellular Combination — CCI

In the Vodafone India–Idea Cellular combination proceedings, the CCI examined the market for provision of passive infrastructure through telecom towers.

The Commission noted that tower operators construct and maintain towers and lease them to telecom service providers, while telecom operators may also maintain their own towers and lease excess capacity.

The case demonstrates the importance of considering:

• tower ownership;
• shared tenancy;
• alternative infrastructure providers;
• market shares;
• vertical relationships;
• effects of consolidation.

Principle

Merger analysis involving telecom operators must account for the parties' ownership and use of passive infrastructure as well as their relationships with independent tower companies.

5. ATC Telecom Tower Corporation / KEC International — CCI Combination Case No. C-2015/04/269

The CCI examined ATC's acquisition of passive infrastructure assets consisting of telecom towers and related movable assets from KEC International.

The Commission identified passive infrastructure as including telecom towers and power-backup facilities and recognised that such infrastructure can be shared among telecom operators.

This demonstrates that consolidation among infrastructure providers can require competition scrutiny even where the infrastructure provider is not itself a retail telecom operator.

Principle

Competition analysis must consider the structure of the upstream infrastructure market, not merely competition between retail telecom operators.

6. CK Telecoms UK Investments Ltd. v European Commission, Case T-399/16

This General Court judgment concerned the proposed Hutchison/Telefónica transaction in the UK mobile telecommunications sector.

Network-sharing arrangements were an important part of the Commission's theory of competitive effects.

The Court examined whether the Commission had adequately demonstrated that the transaction would interfere with incentives to invest in network infrastructure through existing sharing arrangements.

The case illustrates the complexity of assessing the interaction between:

• network sharing;
• investment incentives;
• concentration;
• infrastructure competition;
• non-coordinated effects.

Principle

The existence of network-sharing agreements does not itself establish an anti-competitive effect; the authority must demonstrate how the transaction or arrangement affects actual competitive incentives.

7. Additional Relevant Authorities

Telefónica Deutschland / E-Plus

The European Commission's review of the Telefónica/E-Plus merger required commitments concerning wholesale access, including capacity-based wholesale arrangements, national roaming and passive radio-network sharing.

This demonstrates that infrastructure-sharing remedies can be used to preserve access for competitors following consolidation.

Hutchison 3G UK / Telefónica Ireland

The Commission's merger commitments also expressly addressed the relationship between the merged network and infrastructure/site-sharing arrangements.

8. Passive Sharing vs Active Sharing

EU guidance expressly states that passive sharing is generally less likely to produce restrictive effects where operators retain substantial independence and access to passive infrastructure is not restricted.

9. Essential-Facility Dimension

Passive infrastructure sharing can overlap with the essential-facilities doctrine.

A competition authority may examine:

1. Whether the infrastructure is indispensable;
2. Whether duplication is economically or technically feasible;
3. Whether the infrastructure owner is dominant;
4. Whether access has been refused;
5. Whether the refusal eliminates effective competition;
6. Whether there is an objective justification.

However, mere importance is not necessarily the same as indispensability.

A tower may be commercially valuable without being legally classified as an essential facility if competing infrastructure can reasonably be constructed.

10. Regulatory and Competition-Law Interaction in India

Indian telecom regulation is particularly relevant because passive infrastructure sharing is supported by sectoral policy.

TRAI's recommendations have recognised sharing of infrastructure such as:

• buildings;
• towers;
• electrical equipment;
• batteries;
• power plants;
• dark fibre;
• duct space;
• rights of way. 

Therefore, competition law should not be understood as prohibiting infrastructure sharing. Instead, it operates to prevent anti-competitive implementation of an otherwise legitimate sharing arrangement.

11. Pro-Competitive Effects

Passive infrastructure sharing may produce significant benefits.

Cost reduction

Operators avoid constructing duplicate towers and power systems.

Faster deployment

A new operator can obtain access to existing infrastructure rather than waiting for new construction.

Rural connectivity

Sharing can make deployment economically feasible in areas where independent construction would be costly.

Environmental benefits

Reduced duplication can reduce:

• land requirements;
• construction;
• energy consumption;
• visual infrastructure;
• material use.

Consumer benefits

Cost savings and faster rollout may ultimately improve:

• coverage;
• network availability;
• service quality;
• affordability.

EU telecommunications legislation expressly recognises passive infrastructure sharing as potentially useful for expanding high-capacity connectivity, particularly where duplication is economically or physically difficult.

12. Potential Anti-Competitive Effects

Conversely, sharing may create risks where it:

• eliminates independent network competition;
• restricts network investment;
• facilitates coordination;
• creates discriminatory access;
• raises rivals' costs;
• enables exclusion;
• creates excessive switching costs;
• restricts access to strategically important sites;
• facilitates exchange of sensitive information.

The European Commission has specifically identified the possibility that infrastructure sharing may reduce the number and location of independently determined sites, affect rollout timing and reduce capacity investment.

13. Factors Competition Authorities Should Examine

A competition-law assessment should normally consider:

Market structure

• Number of MNOs
• Market shares
• Concentration
• Entry barriers

Infrastructure availability

• Number of independent tower providers
• Alternative sites
• Replicability
• Geographic coverage

Agreement structure

• Duration
• Exclusivity
• Termination rights
• Capacity commitments
• Pricing arrangements

Degree of cooperation

• Passive equipment only
• RAN sharing
• Spectrum sharing
• Joint network planning

Information exchange

• Type of information
• Frequency
• Accessibility
• Internal safeguards

Competitive independence

• Independent pricing
• Independent network rollout
• Independent quality decisions
• Independent investment strategies

Consumer effects

• Coverage
• Quality
• Prices
• Innovation
• Rural deployment

14. Key Distinction: Passive Sharing vs Collusive Coordination

A crucial distinction is:

Infrastructure sharing ≠ price coordination.

Two competing operators may legitimately share towers while continuing to compete independently on:

• prices;
• packages;
• customers;
• advertising;
• service quality;
• spectrum strategy;
• technological innovation.

The greater the sharing arrangement extends into strategic network decisions, the greater the need for competition-law scrutiny.

15. Compliance Measures

Telecom operators and infrastructure companies can reduce competition risks through:

1. Clearly defined scope of sharing
2. Non-discriminatory access rules
3. Transparent pricing methodologies
4. Objective technical criteria
5. Independent commercial decision-making
6. Information-access controls
7. Confidentiality protocols
8. Clean teams where necessary
9. Restrictions on commercially sensitive information
10. Periodic competition-law audits
11. Reasonable termination provisions
12. No unnecessary exclusivity

16. Short Hypothetical Example

Suppose A Telecom and B Telecom compete in the same city.

A owns 70% of strategically located towers.

B requests access to 200 towers.

A provides access to only 20 sites while providing substantially more favourable access to an affiliated operator.

A competition authority would examine:

• whether A is dominant;
• whether the relevant market is local or national;
• whether alternative towers exist;
• whether the requested sites are technically feasible;
• whether A has an objective justification;
• whether the discrimination affects B's ability to compete.

If A's refusal substantially restricts B's ability to compete and A possesses market power, the conduct could potentially raise abuse-of-dominance concerns.

17. Key Legal Principles from the Case Law

18. Conclusion

Passive infrastructure sharing is generally capable of being pro-competitive and efficiency-enhancing, but its competitive effects depend heavily on market structure and the terms of cooperation.

The central competition-law questions are:

Who controls the infrastructure?

Is access available on reasonable and non-discriminatory terms?

Can competitors realistically replicate the infrastructure?

Do the sharing parties remain independently competitive?

Does the arrangement facilitate exclusion, coordination or reduced investment?

Indian law, particularly Sections 3 and 4 of the Competition Act, 2002, therefore does not treat passive infrastructure sharing as inherently unlawful. The principal concern is how sharing affects access, independence, investment, market entry and competitive conditions. The CCI's treatment of the BSNL–Indus Towers dispute and its telecom merger decisions demonstrates the importance of defining the relevant infrastructure market and examining actual competitive effects. EU jurisprudence similarly distinguishes relatively limited passive sharing from deeper RAN, spectrum and strategic cooperation.

Exam takeaway: Passive infrastructure sharing is normally efficiency-enhancing, but competition concerns arise where sharing creates bottleneck control, discriminatory/refused access, excessive exclusivity, sensitive information exchange, reduced independent investment, or coordination among competing network operators.
