Government Strengthens Rural 4G Connectivity Through 4G Saturation Project

1. At a Glance

• 4G Saturation Project: a project of the Department of Telecommunications (DoT) to bring 4G mobile service to 24,680 villages that had no coverage. BSNL builds the sites using India's own (Atmanirbhar) 4G technology stack, and the project is paid for through the Universal Service Obligation Fund (USOF), now called Digital Bharat Nidhi (DBN) [1][2][6].
• "Saturation" means covering every remaining unserved village, not just the easy ones. Progress is measured by how many villages still have no 4G, not by subscriber counts [1].
• Why it matters for UPSC: it sits where several syllabus themes meet: the digital divide, last-mile delivery to tribal and remote areas, public sector (BSNL) vs private operators, self-reliance in telecom technology, and the use of the USOF/DBN fund [1][2][4].

2. Why in the News

• A PIB release (DoT) reports a fall of nearly 75% in villages without 4G: from 45,180 in 2022 to 11,372 in 2026 [1].
• 18,291 BSNL sites have been commissioned out of the 24,680-site plan. On their busiest day, in October 2026, these sites served 10,21,048 active users [1].
• The Government has sanctioned 26,000 more mobile network sites for the next phase, aimed at the gaps that remain [1].

3. Background & Evolution

• Rationale: closing the digital divide so that rural, remote and underserved people can use digital governance, education, healthcare and financial services [1].
• Milestones (chronological):
• Cabinet approval of the 2G-to-4G upgrade of mobile sites at security locations in Left Wing Extremism (LWE) areas. This was a related, earlier initiative [7].
• 27 July 2022: the Union Cabinet approves 4G saturation of uncovered villages at ₹26,316 crore. The cost covers capital spending plus 5 years of operating costs. Scope: 24,680 uncovered villages, plus an upgrade to 4G for 6,279 villages that had only 2G/3G [2].
• 2022 Year-End Review: completion was targeted for December 2023 [3]. The 2026 figures show the rollout ran well past that date [1].
• September 2025: the PM inaugurates BSNL's indigenous 4G stack and one lakh indigenous BSNL towers [5]. The stack combines a C-DOT core network, Tejas Networks radio equipment and TCS as system integrator. This puts India among five countries with a fully home-grown 4G stack [4].
• February 2026: about 61% of planned towers have been commissioned, according to a PRS summary of a parliamentary committee report [6].
• 2026: villages without 4G fall to 11,372; the next phase of 26,000 sites is sanctioned [1].

5. Multi-Dimensional Analysis

Economic

• The project spends public money (₹26,316 crore from the USOF) where private operators may not find a business case [1][2].
• Sharing networks and making better use of existing towers lowers the cost of covering each remote village [1].
• Heavy use of the new sites (10.2 lakh active users on the peak day) suggests real demand that had gone unserved, not idle assets [1].

Social

• The project targets remote tribal habitations, scattered settlements and aspirational regions, where people had no other way to reach digital services [1].
• Mobile connectivity is the basis for using digital governance, education, health and financial services [1].

Scientific / Technological

• The rollout uses home-grown technology (C-DOT core, Tejas radio, TCS integration), which makes India one of only five countries with its own 4G stack [4].
• A parliamentary committee review (via PRS) found coverage gaps, weak signal strength and duplicated infrastructure in third-party audits of DBN mobile connectivity projects [6].

Administrative

• Commissioning stood at about 61% of planned towers by February 2026 [6] and about 74% (18,291 of 24,680) in the 2026 release [1], against an original December 2023 deadline [3].
• DoT coordinates two channels at once: BSNL builds the government project, while private operators expand rural coverage through their own networks [1].

Geopolitical / Strategic

• Covering LWE-affected and border/remote areas, and using an indigenous stack, reduces dependence on foreign telecom vendors and supports internal security communications [4][7].

6. Recent Developments (last 12–18 months)

• September 2025: indigenous 4G stack and one lakh BSNL towers launched nationwide [4][5].
• February 2026: about 61% of planned saturation towers commissioned, with the parliamentary committee raising concerns about audits [6].
• October 2026: peak of 10,21,048 active users in one day across the saturation sites [1].
• 2026: villages without 4G down to 11,372; 26,000 more sites sanctioned for the next phase [1].

7. Prelims Hooks

• The Cabinet approved 4G saturation of uncovered villages on 27 July 2022 [2].
• Total cost: ₹26,316 crore, covering capex and 5 years of opex [2].
• Target: 24,680 uncovered villages [1][2].
• It also upgrades 6,279 villages from 2G/3G to 4G [2].
• Implementing agency: BSNL, not a private operator and not C-DOT [1][2].
• Funded through the USOF, now Digital Bharat Nidhi [2][6].
• The project uses an indigenous 4G stack: C-DOT core + Tejas Networks radio + TCS as integrator [4].
• India is one of five countries with a fully indigenous 4G stack [4].
• Villages without 4G: 45,180 (2022) → 11,372 (2026), a fall of about 75% [1].
• 18,291 sites commissioned under the 24,680-site plan [1].
• Peak daily active users: 10,21,048 (October 2026) [1].
• Next phase: 26,000 additional mobile sites sanctioned [1].
• Original completion target: December 2023 [3].

8. Three "Progress" Numbers That Measure Different Things

• The 75% fall in uncovered villages is not BSNL's work alone
• The number of villages without 4G fell from 45,180 to 11,372. That is about 33,800 villages connected [1].
• BSNL has commissioned only 18,291 saturation sites [1].
• The rest of the fall also counts private operators growing their own rural networks [1].

• So do not write "the 4G Saturation Project connected 75% of uncovered villages". The national gap fell by 75%, and the project is one part of that.

• 61% and 74% are both correct, for different dates

• About 61% of planned towers were commissioned by February 2026. That figure comes from the parliamentary committee [6].
• About 74% (18,291 of 24,680) appears in the later 2026 PIB release [1].

• In an answer, always give the date and the source with the percentage.

• A third number covers all DBN projects together

• A Lok Sabha reply put 23,426 of 33,409 towers on-air as of 30 June 2026 [8]. On-air means switched on and giving service.
• That count includes every mobile project funded by Digital Bharat Nidhi (LWE, Aspirational Districts, border areas and others), not just saturation [6][8].

• If you mix it with the 24,680 figure, your answer will contradict itself.

• "Commissioned" does not mean "working well"

• Third-party audits of DBN mobile projects found coverage gaps and weak signal [6].
• A tower can be counted as built and still give poor service. The next section shows this has happened before.

9. The LWE Tower Project Already Showed Where This Can Fail

• Phase I of the LWE mobile project had the same design as this one
• It was funded by USOF and given to BSNL on nomination basis, meaning no competitive bidding [9].

• Final cost: about ₹4,214 crore. Planned sites: 1,836 [9].

• It started late and stayed late

• The USOF–BSNL agreement was due by September 2013 but was signed only in September 2014 [9].
• Commissioning missed schedule even after the time allowed was more than doubled [9].

• The saturation project shows the same pattern: target December 2023 [3], still about 74% complete in 2026 [1].

• Towers were built but often did not work

• The benchmark was 98% uptime, meaning the share of time a tower is actually working.
• Only about 19.56% of the 1,831 LWE sites met it in April–September 2017 [9].
• The Home Ministry and state police complained about dead towers in 2015. USOF simply passed the complaints to BSNL and did not test the towers itself [9].

• Monitoring agencies were appointed only in December 2016, with a narrow role [9].

• Why it matters now

• The 2026 committee again found coverage gaps, weak signal and duplicated infrastructure in DBN projects [6].

• The lesson from 2021 has still not been fully applied. The fund pays for building towers, but it does not check closely enough whether they keep working.

• The hardest places are still behind

• LWE areas: about 93% of planned 4G towers commissioned. Border outposts: only 42% (February 2026) [6].
• The committee named the reasons: difficult terrain, security risks, slow forest clearances and logistics [6].
• The last 11,372 villages [1] are likely to be the most difficult and most costly to reach, so progress will probably slow down.

10. Who Pays to Keep the Towers Running After Year Five?

• The ₹26,316 crore covers only five years of running costs
• The outlay includes capex (cost of building) plus 5 years of opex (cost of running: power, repair, staff) [2].

• After that, someone must keep paying for each remote tower.

• These sites earn little

• 10,21,048 peak-day users across 18,291 sites [1] works out to about 56 users per site on the busiest day.

• That is very low use per tower. It explains why private operators stayed away, and why these towers cannot pay for themselves.

• BSNL is the one expected to carry this cost, and it is still loss-making

• About 41% of the telecom budget for 2026-27 goes to the BSNL and MTNL revival plan. Both companies keep recording losses [10].
• This includes ₹28,473 crore of capital infusion (fresh government money) into BSNL [10].

• BSNL's first quarterly profit since 2007, in late 2024-25, was a single quarter, not a recovery [10].

• Parliament has already raised this

• The Committee on Public Undertakings asked BSNL and DoT to closely track whether 4G actually raises BSNL's revenue [11].
• If it does not, the saturation sites will either need a permanent subsidy from DBN or face the same uptime decline seen in the LWE project [9].

11. Should BSNL Alone Have Been Given the Job?

• The strongest argument against the BSNL-only route
• Giving projects to BSNL on nomination basis has a weak record. The LWE Phase I project was late and most of its towers missed uptime targets [9].
• Without competition, there is no rival bidder offering better terms, and BSNL is not penalised much for delays.

• DBN money also has other uses. BharatNet funds have been underused since 2022-23, and only 30% of gram panchayats had a functional BharatNet connection [6][10]. Building more assets does not automatically mean they get used.

• What this argument gets right

• The deadline slipped by about three years [1][3].
• Audits found weak signal and duplicated towers [6].

• Those are real costs of the nomination model, and the committee itself asked for stronger contracts [10].

• Why the government's choice still holds up

• Private operators did not build in these villages for years, because about 56 peak-day users per site [1] is not a business case.

• Using the indigenous stack (C-DOT core + Tejas + TCS) gives BSNL steady demand for Indian technology. It also reduces dependence on foreign vendors in LWE and border areas [4][7].

• A fair conclusion for Mains

• The problem is not mainly that BSNL was chosen. The problem is that BSNL was chosen with weak penalties and weak checking.
• The fix is to change the contract, not the implementer (see next section).

12. What Each Actor Should Do Next

• DoT / DBN: pay for uptime, not just for towers built
• CAG pointed out that BSNL could have faced subsidy cuts for missing the 98% uptime benchmark [9].
• The parliamentary committee recommended stronger contracts and performance-linked incentives for PSUs [10].

• Put together: release the subsidy for the next 26,000 sites [1] only when sites show working uptime and signal strength.

• DBN: order a state-wise performance audit before the next phase

• The committee recommended a state-wise performance audit and better pre-project appraisal [10].

• This should come before the 26,000 new sites [1] are placed, so that the duplicated towers found in audits [6] are not built again.

• MHA and state governments: clear the ground for the hardest sites

• The committee asked for logistics and security support for implementing agencies in security-sensitive zones, and for time-bound commissioning [6].

• Forest clearances are a named cause of delay [6]. States can speed them up for single-tower sites.

• Operators in the north-east: share towers instead of each building their own

• The committee recommended infrastructure sharing between telecom operators in the north-east [6].

• Sharing lowers the cost of each remote site, which is the main reason these villages were left out in the first place [1].

• BSNL and DoT: track revenue, not just users

• The Committee on Public Undertakings asked them to monitor 4G's effect on BSNL's revenue [11].
• Usage numbers like the 10.2 lakh peak users [1] should be published together with per-site uptime. Then success means service that keeps working, not just towers that were built.

13. Anchors for Answers

• Data: Villages without 4G fell from 45,180 (2022) to 11,372 (2026), the national gap including private operators [1]; about 61% of saturation towers commissioned by February 2026 [6]; only 42% of border-outpost towers commissioned, against 93% in LWE areas [6].
• Data: Only 19.56% of LWE Phase I sites met the 98% uptime benchmark (April–September 2017) [9].
• Report/Committee: Standing Committee on Communications and IT, report on schemes under Digital Bharat Nidhi (August 2026): found coverage gaps, weak signal and duplication; recommended a state-wise audit and performance-linked incentives [6][10].
• Report/Committee: CAG Report No. 3 of 2021, performance audit of the USOF LWE mobile project (Phase I) [9]; Committee on Public Undertakings, 15th Report (2025-26) on BSNL's 4G rollout [11].
• Law/Case: Telecommunications Act, 2023, the framework under which USOF became Digital Bharat Nidhi (verify the exact section before the exam) [6].
• Scheme: BharatNet, the same DBN fund: only 30% of gram panchayats had a functional connection by February 2026, showing the same gap between building assets and getting them used [6][10].

14. Mains Relevance

• GS-II: government policies and interventions for development; e-governance; welfare of vulnerable sections (tribal areas).
• GS-III: infrastructure (telecom); inclusive growth; indigenisation of technology; security challenges in LWE areas.
• Possible question stems: 1. "Saturation, not coverage, is the true test of bridging India's digital divide." Examine this with reference to the 4G Saturation Project. 2. Discuss the role of Digital Bharat Nidhi and BSNL in last-mile rural connectivity. What challenges hold back saturation in tribal and remote areas? 3. "Indigenous telecom stacks combine strategic autonomy with developmental goals." Critically evaluate this in the context of BSNL's 4G rollout.

16. NCERT Concepts to Revise

• Digital Bharat Nidhi (Economy): The fund that pays for the project; it is the renamed USOF and also funds BharatNet.
• Universal service obligation (Economy): The idea behind USOF: telecom must reach remote areas even where private operators see no profit.
• Bharat Sanchar Nigam Limited (Economy): The public sector firm that builds and runs the saturation sites; its finances decide whether they last.
• Digital divide (Geography): The core problem the project tackles: rural and tribal areas lacking mobile and internet access.
• Last-mile connectivity (Economy): Reaching the last unserved villages is the costliest step, and the project's whole purpose.
• Department of Telecommunications (Polity): The department that designed and oversees the project and the fund behind it.
• Telecommunications Act 2023 (Polity): The law under which USOF became Digital Bharat Nidhi.
• Atmanirbhar Bharat (Economy): The project runs on India's home-built 4G stack, a self-reliance policy goal.
• Self-reliance (Economy): Home-grown telecom technology reduces dependence on foreign vendors, a Mains angle in this note.
• BharatNet (Geography): The rural fibre scheme, funded by the same fund, shows the gap between building assets and using them.
• Performance audit (Polity): The CAG's audit of the earlier LWE tower project found most towers missed uptime targets.
• Committee on Public Undertakings (Polity): This committee asked BSNL and DoT to track whether 4G raises BSNL's revenue.
• Comptroller and Auditor General (Polity): CAG's 2021 report on the LWE mobile project is a key source of lessons for this one.
• Subsidy (Economy): The fund works as a subsidy for unprofitable sites, and the note suggests linking it to uptime.
• Tendering (Economy): Gives BSNL the work on nomination without competitive bidding, the weakness the note criticises.

17. Common Errors / Trap Areas

• Two different 24,680 figures: 24,680 is the village target [2] and also the planned site count in the 2026 release [1]. The remaining national gap is a separate number, 11,372 villages [1]. Don't mix them up.
• Wrong implementing agency: the project is DoT's, executed by BSNL. C-DOT develops the technology, and private telecom operators are not the implementers [1][4].
• Fund name: USOF has been renamed Digital Bharat Nidhi; it is not a new, separate fund [2][6]. Its legal basis is the Telecommunications Act, 2023, but none of the sources retrieved for this note confirm that, so verify it before an exam.
• Wrong timeline: completion was targeted for December 2023 [3], but the project was still in progress in 2026 [1].
• Wrong scope: the project also upgrades 6,279 villages that had only 2G/3G. It is not limited to villages with zero coverage [2].
