What are the biggest unsolved problems in deploying private 5G networks across industries like manufacturing, logistics, and energy?

Three critical obstacles continue to block widespread private 5G deployment despite technological maturity.

Spectrum licensing remains the most complex barrier, with enterprises facing regulatory hurdles and high costs to access licensed mid-band frequencies. While CBRS democratizes access in the U.S., most enterprises still rely on shared spectrum with limited guarantees, and acquiring dedicated licensed spectrum can cost millions through auction processes.

Integration complexity creates the second major bottleneck, as private 5G networks must seamlessly connect with existing Wi-Fi, Ethernet, OT systems, and cloud platforms. This requires specialized orchestration tools that are still maturing, and many enterprises lack the technical expertise to manage hybrid network environments effectively.

The talent shortage represents perhaps the most persistent challenge, with critical gaps in RF engineering, edge computing, and cybersecurity professionals needed to design, deploy, and maintain private 5G networks. This skills deficit slows rollouts and increases deployment costs across all industrial sectors.

Which private 5G startups are getting funded right now, and what exactly are they building?

Venture funding continues to flow into private 5G startups focused on specific technical challenges and vertical solutions.

What are the key R&D challenges that startups are trying to solve in the private 5G space?

Startups are concentrating on four critical technical areas that determine private 5G network performance and viability.

RAN optimization represents the primary focus, with companies developing advanced signal processing techniques to improve spectral efficiency and reduce base station latency. This includes innovations in beamforming algorithms, interference cancellation, and dynamic spectrum allocation that can significantly impact network performance in dense industrial environments.

Edge-core integration challenges require seamless orchestration between on-premises core networks and cloud-native network functions. Startups are building platforms that can automatically manage workload placement, ensure service continuity during failures, and provide consistent performance across hybrid deployments. This is particularly critical for applications requiring guaranteed latency and reliability.

Device ecosystem maturity remains a significant barrier, with startups working to expand the availability of affordable 5G IoT devices with extended battery life for industrial deployments. The limited selection of ruggedized, industrial-grade 5G devices that can operate in harsh environments continues to constrain use case development.

AI-driven network management represents the newest frontier, with companies embedding machine learning capabilities for predictive maintenance, adaptive network slicing, and automated optimization. These systems must learn from network behavior patterns to guarantee service level agreements while minimizing human intervention in network operations.

What are some recent startup failures in private 5G, and what can be learned from them?

The Adani Group's private 5G venture in India provides the most instructive recent failure case study for entrepreneurs and investors.

After paying $27 million for mmWave spectrum licenses in 2022, Adani Group is now planning to surrender the spectrum due to prohibitive rollout costs and failure to meet deployment targets. The company overestimated the return on investment for industrial 5G applications and underestimated the complexity and cost of mmWave network deployment in industrial environments.

The failure highlights three critical lessons for private 5G ventures. First, spectrum acquisition costs must be carefully balanced against realistic revenue projections, as high upfront investments can make business models unviable even with successful technical deployments. Second, mmWave frequencies present significant propagation challenges that dramatically increase infrastructure costs compared to mid-band alternatives. Third, enterprises require proven value propositions before committing to private 5G implementations, making proof-of-concept validation essential before large capital commitments.

AWS's decision to wind down its standalone private 5G core offering also demonstrates market realities, as the company shifted toward telco partnership models rather than direct enterprise sales. This suggests that pure-play private 5G solutions may struggle against integrated offerings from established network operators and cloud providers.

How mature is the current ecosystem in terms of hardware, software, spectrum, and integration tools for private 5G?

The private 5G ecosystem shows significant maturity in hardware and spectrum access but continues developing in software orchestration and integration capabilities.

Hardware availability has reached commercial readiness with established vendors like Nokia, Ericsson, and Samsung providing complete RAN and core network solutions. However, most equipment is optimized for public network scale rather than enterprise deployments, creating cost and complexity challenges for smaller private networks. Specialized industrial hardware for harsh environments remains limited but is improving rapidly.

Software development focuses on virtualization and orchestration platforms, with increasing adoption of cloud-native architectures and container-based deployments. O-RAN adoption is accelerating interoperability between vendors, but vendor lock-in concerns persist as many solutions remain proprietary. Open-source alternatives are emerging but lack the support ecosystems of commercial platforms.

Spectrum democratization through CBRS in the United States and similar mid-band allocations in Europe and Asia have significantly lowered entry barriers for private 5G deployments. Shared spectrum frameworks reduce licensing costs while providing adequate performance for most industrial applications. However, spectrum availability varies significantly by geographic region and regulatory framework.

Integration tools represent the least mature ecosystem component, with AI-powered orchestration platforms still in early development stages. Most deployments require custom integration work and specialized expertise, limiting scalability for smaller enterprises. Standardization efforts are ongoing but adoption remains fragmented across different industry verticals.

What regulatory or infrastructure barriers still make private 5G deployment difficult or expensive?

Regulatory fragmentation and infrastructure requirements create persistent deployment barriers despite improving spectrum access policies.

Global spectrum regulations vary dramatically by country, with many markets still restricting enterprise access to licensed frequency bands. While the United States has pioneered CBRS shared spectrum access, European markets maintain more restrictive licensing regimes that favor traditional telecom operators. Asian markets show mixed approaches, with some countries opening mid-band spectrum for private use while others maintain strict operator-only policies.

High deployment costs continue to deter mid-sized enterprises from moving beyond pilot projects, as complete private 5G implementations can require millions in capital expenditure for equipment, installation, and ongoing maintenance. These costs are particularly challenging for smaller facilities that cannot achieve economies of scale in their network investments.

Permitting and site survey requirements add significant time and expense to deployments, particularly for indoor/outdoor hybrid networks requiring multiple base stations and backhaul connections. RF propagation modeling and interference analysis require specialized expertise that many enterprises lack internally, forcing reliance on expensive consulting services.

Cross-border roaming and interconnection standards remain underdeveloped, limiting the utility of private 5G networks for global enterprises with multiple facilities. Standardization bodies are working on these issues, but implementation will require years of coordination between national regulators and industry stakeholders.

What are the different business models private 5G startups are using, and which ones have shown the most profitability or scalability?

Four distinct business models have emerged in the private 5G market, with managed services and NaaS subscriptions showing the strongest financial performance.

• Network-as-a-Service (NaaS): OPEX-based subscription models for managed private 5G networks have demonstrated profit margins above 15% in logistics applications due to predictable recurring revenue streams and reduced customer capital requirements
• System Integrator Partnerships: Bundled services combining deployment, operations, and optimization through established SI relationships provide market access but typically operate on lower margins due to partner revenue sharing
• Spectrum Leasing: Operator-managed CBRS or local licensing agreements that reduce customer CAPEX while providing guaranteed spectrum access, particularly effective in dense industrial areas
• Turnkey "Network-in-a-Box": Plug-and-play solutions targeting SMEs for rapid deployment, showing promise in standardized environments but struggling with customization requirements

The most successful startups combine multiple models, offering flexibility to match customer preferences and risk tolerance. Celona's cloud-managed platform exemplifies this approach, providing both direct enterprise sales and channel partner models depending on customer size and complexity requirements.

Which problems in private 5G are not solvable with current technology, and what might change that in the next 5 years?

Two fundamental technical limitations constrain private 5G capabilities today but may be addressable through emerging technologies.

True seamless macro-to-private roaming remains technically challenging due to core network integration gaps and SIM management complexities. Current implementations require manual configuration and specialized equipment that prevents fluid movement between public and private networks. This limitation particularly affects mobile workforce applications and multi-site enterprise deployments.

Ultra-dense mmWave coverage faces insurmountable propagation and interference challenges that make wide-area deployment impractical without significant infrastructure investment. High-frequency signals require line-of-sight propagation and dense base station deployments that dramatically increase costs and complexity for most enterprise applications.

Potential technological enablers over the next five years include AI-driven beam management systems that could optimize mmWave performance through intelligent interference mitigation and dynamic beamforming. Integrated satellite backhaul solutions may address coverage limitations in remote industrial facilities. Universal SIM frameworks and network slicing standardization could enable seamless roaming between network operators and private deployments.
