A new report from SNS Telecom & IT indicates that annual spending on private 5G networks is projected to surpass $6.6 billion by 2029 as industrial giants scale multi-site, multi-national private 5G deployments across existing and new greenfield facilities to support physical AI, automation and workforce connectivity, alongside a parallel expansion of mission-critical 5G networks for defence forces, public safety agencies, railways and utilities.
Private cellular networks largely remained a fringe solution in the 2G and 3G eras, although GSM-R networks for railway communications are still operational ahead of a planned transition to 5G-based FRMCS (Future Railway Mobile Communication System). The early 2010s saw the first installations of private LTE networks, marking the beginning of what has since grown into a well-established but niche segment of the wider wireless infrastructure sector. However, private 5G networks or NPNs (Non-Public Networks) based on 3GPP-defined 5G specifications are increasingly replacing LTE across many verticals, with a market potential far exceeding that of previous technology generations. There continues to be a steady rise in production-grade deployments by household names and industrial giants such as ADNOC, Airbus, ArcelorMittal, BASF, Bayer, BHP, BMW, BP, Cargill, Chevron, COSCO Shipping, DP World, Duracell, Equinor, Ford, Foxconn, Google, Hitachi Rail, Home Depot, Hutchison Ports, Hyundai, Intel, John Deere, LG Electronics, Lufthansa, Meijer, Nestlé, Newmont, PETRONAS, Ricoh, Robert Bosch, Takeda, Tesla, Toyota, Trinity Industries, Volkswagen, Walmart, Whirlpool and Xerox.
Compared to LTE technology, private 5G networks can address far more demanding performance requirements in terms of throughput, latency, reliability, availability and connection density. In particular, 5G’s URLLC (Ultra-Reliable, Low-Latency Communications) and mMTC (Massive Machine-Type Communications) capabilities, along with a future-proof transition path to 6G networks in the 2030s, have positioned it as a viable alternative to physically wired connections for industrial-grade communications between machines, robots and control systems. Furthermore, 5G’s wider coverage radius per radio node, scalability, determinism, security features and mobility support have stirred strong interest in its potential as a replacement for interference-prone unlicensed wireless technologies in IIoT (Industrial IoT) environments, where the number of connected sensors and other endpoints is expected to increase significantly over the coming years.
As end user organizations in the United States, Canada, Germany, United Kingdom, France, Spain, Italy, China, Japan, South Korea, Taiwan, Australia, New Zealand, Brazil and other countries ramp up their industrial intelligence, automation, physical AI and mission-critical communications initiatives, a growing number of private 5G installations have progressed to a stage where practical and tangible benefits – particularly efficiency gains, cost savings and safety – are becoming increasingly evident. For instance, Tesla, Ford, Hyundai, Toyota, LG Electronics, NEC Corporation, Foxconn, Whirlpool, Salzgitter, BASF, Midea, Gree and JD Logistics are just some of the industrial organisations that have eliminated connection-related stoppages since migrating AGV (Automated Guided Vehicle) and AMR (Autonomous Mobile Robot) communications from Wi-Fi to private 5G networks at their manufacturing and logistics facilities, whereas Jaguar Land Rover, BD SENSORS and others have extended connectivity to parts of their plants that were previously left unconnected due to the cost and complexity of wired Ethernet links. Among other impactful industrial examples, automotive engine parts supplier Fulin Precision has freed workers from repetitive box-moving tasks by adopting 100 semi-humanoid robots coordinated by a private 5G-Advanced network. In the public sector, Las Vegas’ municipal private 5G network has contributed to a 90% drop in wrong-way driving incidents, while Mexico City Police has extended immersive VR training sessions from 25 minutes to 1.5 hours and eliminated the need for officers to carry bulky backpacks through a standalone private 5G network.
SNS Telecom & IT’s “Private 5G Market: 2026 – 2030” report projects that annual investments in private 5G networks for vertical industries will grow at a CAGR of approximately 34% between 2026 and 2029, eventually surpassing $6.6 billion by the end of 2029. A substantial proportion of this growth will be led by highly localized networks – including multi-site, multi-national deployments – for physical AI, automation and workforce connectivity in enterprise campuses and industrial facilities. The adoption of physical AI is particularly pronounced, with many industrial giants relying on private 5G-connected AGVs, AMRs, drones, cranes, forklifts, mining vehicles, quadruped robots and even semi-humanoid systems for complex tasks. In parallel, mission-critical communications has emerged as an equally important growth pillar for private 5G adoption among defence forces, public safety agencies, railways, utilities and critical infrastructure operators. Among other features for mission-critical networks, the 3GPP’s Release 18, 19 and 20 specifications for 5G-Advanced systems add support for low 5G NR channel bandwidths in dedicated spectrum, new operating bands and specific enhancements for FRMCS and MCX (Mission-Critical PTT, Video & Data) service implementations.
