Indian Telecom Carriers Face 5G Speeds Squeeze as Data Traffic Surges
In this article (9)
Mobile subscribers in India are consuming an average of 31.1 gigabytes of cellular data each month, driving monthly mobile network traffic to 27.6 exabytes and squeezing real-world 5G connection speeds across major commercial centres.
Monthly 5G volume climbed 70 per cent year over year to 12.9 exabytes, now accounting for 46.8 per cent of all cellular data traffic in the country, according to Nokia’s Mobile Broadband India Traffic Index 2026. Network capacity is falling behind that appetite. Even as carrier icons display 5G service on phone screens, users face sluggish response times and reduced throughput across shopping centres, transport hubs and high-density housing developments.
Traffic Surges Overwhelm Local Cells
Radio cells in major urban corridors now handle simultaneous demand for video streaming, cloud gaming, digital retail checkouts and video conferencing. When thousands of handsets connect to a single base station, available radio spectrum splits across those devices, causing local throughput to fall sharply regardless of advertised network capabilities.
The Telecom Regulatory Authority of India reported that total wireless mobile data consumption reached 84,424 petabytes during the April to June quarter of 2026. That represents an 8.30 per cent quarter-on-quarter increase from 77,953 petabytes. Average monthly wireless data usage per subscriber rose 6.32 per cent to 28.39 gigabytes over the same period.
Reliance Jio reported in its October 2026 financial disclosures that its user base included roughly 300 million 5G customers out of 542 million total connections. Individual monthly data usage on Jio’s network reached 44.2 gigabytes per subscriber, up from 38.7 gigabytes twelve months earlier. Handling that traffic volume demands constant radio densification and high-capacity backhaul lines.
The Backhaul Bottleneck and Indoor Walls
Carrier deployments show rapid physical additions, but transmission feeds from base stations to core networks frequently fall short. Fixed wireless access services have intensified that strain. Home broadband products such as Reliance Jio’s JioAirFiber and Bharti Airtel’s Xstream AirFiber now generate more than 25 per cent of all 5G data traffic in India, locking heavy continuous data streams onto cellular masts.
Physical structural barriers compound the problem. High-frequency 5G radio signals, particularly mid-band 3.3 GHz frequencies, struggle to penetrate concrete walls, metallic cladding and coated window glass in indoor commercial venues. When indoor signal strength falls, base stations downgrade customer devices to more robust but slower transmission modulations, cutting download rates.

Regulator drive tests conducted in July 2026 across Kolkata, Howrah and Hooghly logged 122 poor-signal samples for Airtel, 181 for Jio, 401 for Vodafone Idea and 3,904 for state-run BSNL across roughly 65,000 samples per operator along 309.7 kilometres of roadways and hotspots. Cellular operators rely on hardware vendors like Ericsson, Nokia, Samsung Networks and Mavenir for carrier aggregation and active antenna arrays, but equipment on towers cannot bypass missing fibre lines.
Operator Speeds and Consumer Grievances
Performance gaps between operators remain wide in field measurements. Testing conducted by nPerf across real users between April 2025 and March 2026 showed Bharti Airtel leading average download performance at 113.81 megabits per second, with an upload rate of 16.84 Mbps and latency of 58.98 milliseconds. Reliance Jio recorded 94.22 Mbps down, 8.97 Mbps up and latency of 62.09 milliseconds.
Vodafone Idea trailed with average download speeds of 75.80 Mbps, higher upload speeds of 14.51 Mbps and elevated latency of 111.60 milliseconds. BSNL delivered 15.11 Mbps down and 5.45 Mbps up, reflecting its reliance on an indigenous 4G network deployed with TCS, Tejas Networks and C-DOT. State filings showed BSNL operated 95,511 active 4G sites out of 97,672 installed units as of January 15, 2026.
Capital Allocation and Network Expansion
Private operators have pursued diverging technical strategies to maintain performance. Reliance Jio built its standalone 5G network from the outset, whereas Bharti Airtel expanded via non-standalone 5G configurations while adding infrastructure. Airtel deployed more than 2,900 new 5G sites across Punjab, Haryana, Himachal Pradesh and Jammu and Kashmir over 12 months, covering 77 districts, alongside 2,750 sites in Gujarat.
Vodafone Idea is executing a phased catch-up strategy. After servicing 43 cities across 17 priority circles, the company mapped out an expansion in March 2026 targeting 90 additional cities to reach 133 municipal markets. Network equipment suppliers including Nokia, Ericsson and Samsung have secured rollout contracts to modernize Vi’s physical gear, but spectrum density in residential districts remains thin.
Retailers and mobile commerce operators rely directly on cellular network stability at the point of sale. Digital payments, dynamic in-store inventory tracking and rapid logistics fulfillment require low-latency cell handoffs that degraded 5G connections fail to deliver during peak foot-traffic hours. The pressure now shifts to municipal fibre approvals and small-cell indoor installations.
The next major performance test will come as Vodafone Idea works to operationalize its expanded 133-city footprint.
Questions & Answers
Q.Why are 5G speeds slowing down despite phones showing active coverage?
Why are 5G speeds slowing down despite phones showing active coverage?
High mobile data consumption splits available radio spectrum across thousands of handsets connected to single urban base stations, sharply reducing local throughput. Also, transmission feeds from masts to core networks frequently fall short because operators lack sufficient high-capacity fibre backhaul lines.
Q.How much are fixed wireless home broadband services contributing to network congestion?
How much are fixed wireless home broadband services contributing to network congestion?
Fixed wireless access services such as Reliance Jio’s JioAirFiber and Bharti Airtel’s Xstream AirFiber generate more than 25 per cent of all 5G data traffic in India. These home broadband products lock heavy, continuous data streams onto cellular masts, substantially increasing strain on mobile infrastructure.
Q.Why do indoor commercial venues suffer from particularly poor signal reception?
Why do indoor commercial venues suffer from particularly poor signal reception?
High-frequency 5G radio signals, especially mid-band 3.3 GHz frequencies, struggle to penetrate concrete walls, metallic cladding and coated window glass. When indoor signal strength drops, base stations automatically downgrade connected devices to slower transmission modulations, significantly cutting data download rates for shoppers and retailers.
Q.Which Indian telecom operator currently provides the fastest real-world speeds?
Which Indian telecom operator currently provides the fastest real-world speeds?
Bharti Airtel recorded the fastest performance in real-user testing, averaging download speeds of 113.81 megabits per second alongside latency of 58.98 milliseconds. Reliance Jio followed with average download speeds of 94.22 Mbps, whilst Vodafone Idea and state-run BSNL trailed at 75.80 Mbps and 15.11 Mbps respectively.
