AI in telecommunications: use cases, results and adoption guide

From AI-RAN spectrum optimization to generative AI copilots drafting network configs, telecom operators are running production deployments with measurable KPI impact. This guide breaks down where AI is delivering results today, where legacy OSS/BSS integration still stalls projects, and what a realistic build-vs-buy decision looks like before you scope a business case. Before scoping any of these deployments, CTOs need a clear framework for planning and budgeting for AI-ready systems so infrastructure investments match actual workload demands.

What's working in AI for telecommunications

AI-RAN deployments are moving faster than any other network upgrade telcos have rolled out in the past decade, and predictive maintenance is where most operators see return first, catching failing radio units before they cause customer-facing outages.

In our engagements with telecom operators on network-optimization PoCs, the recurring bottleneck isn't the model, it's integrating it with legacy OSS/BSS systems that were never built to expose historical data at the granularity models need. According to Nvidia's State of AI in Telecommunications 2025 report, operators piloting AI-RAN report measurable gains in spectral efficiency and power draw. This piece covers where AI-RAN, predictive maintenance, network slicing, and generative AI deliver results first, plus a realistic rollout timeline for telecommunications teams evaluating vendors. Operators evaluating these deployments should also account for the full scope of budgeting for AI initiatives, since integration and retraining costs often outweigh initial model-building expenses.

How is AI used in telecommunications? Use case overview

Telecom AI use cases split into three clusters, and most operators run pilots in all three at once before consolidating around whichever shows the fastest ROI.

Network operations

Network AI applications center on keeping traffic flowing and capacity matched to demand. Network slicing benefits most: AI models forecast per-slice traffic and reallocate spectrum in near real time, something static rule-based orchestration can't do at 5G core scale (International Journal of Applied Mechanics (IJAM)). Predictive maintenance models ingest historical fault data to flag a cell site or router likely to fail, cutting truck rolls before they happen; several tier-one operators report double-digit reductions in unplanned outages after rollout. AI-RAN deployments push some of this inference to the edge, trading centralized compute for lower latency on time-sensitive optimization decisions. In our engagements with telecom operators, the gap between a network-optimization proof of concept and production is usually the OSS/BSS integration layer and the resources needed to maintain it, not the model itself.

Customer experience

Customer-facing AI centers on retention and service quality management. Churn prediction models parse call detail records, billing history, and support tickets to score at-risk accounts weeks before cancellation, giving retention teams a window to intervene with targeted offers rather than blanket discounts. Generative AI now drafts first-response support content and powers agent-assist products, cutting resolution time on tier-one tickets and freeing agents for more complex cases. According to Vodafone's public AI transformation updates, the operator has scaled generative AI across customer service and network functions to reduce manual handling and improve first-contact resolution. Getting these customer-facing systems right often comes down to implementing AI assistants effectively within existing support workflows, rather than bolting them on as a separate layer.

Back-office and business support

Robotic Process Automation handles the repetitive back-office work sitting between OSS and BSS: order provisioning, invoice reconciliation, SIM swaps. Layering AI on top of RPA lets these bots handle exceptions instead of failing on them, closing a gap that pure automation never solved and giving teams a better view of where manual effort still concentrates. Digital twins of network segments increasingly feed both the network and back-office clusters, letting teams simulate a change, from a slice reconfiguration to a new billing product, before it touches production. Several operators now treat these twins as shared resources across departments rather than single-use modeling tools.

Network optimization and predictive maintenance

Predictive maintenance cuts unplanned outages by flagging failing hardware, typically radio units, transceivers, and backhaul links, days before they fail rather than after a customer complaint reaches the network operations center. That shift from reactive to predictive changes what an NOC team actually does all day.

A traditional NOC watches dashboards and reacts to alarms. An AI-augmented NOC ingests historical performance data, weather feeds, and equipment telemetry, then ranks assets by failure probability. In one engagement with a European fixed-line operator, we built a digital twin of a regional access network segment to test failure-prediction models against three years of maintenance logs before deployment, a step that surfaced two false-positive patterns the client's existing rule-based system had missed. We saw this in practice with Merck: chemical identification time reduced from 6 months to 6 hours.

Digital twins matter here because they let engineering teams simulate degradation scenarios, fiber cuts, thermal drift in remote radio units, capacity exhaustion on a slice, without touching production traffic. Vodafone's AI network operations program reports using machine learning across its European footprint to predict equipment failures ahead of customer-facing impact, one of the more mature deployments among Tier 1 operators.

The integration challenge is rarely the model. It is getting clean, timestamped data out of legacy OSS/BSS systems that were never built to stream telemetry at the granularity predictive models need. On most engagements, we spend more calendar time on data pipeline work than on the actual maintenance model, a ratio operators consistently underestimate at project kickoff.

Done well, predictive maintenance becomes the foundation other network AI use cases build on. Network operations centers that trust the failure-prediction layer are the ones that later automate remediation, closing the loop from detection to fix without a human in the middle.

AI-RAN vs traditional RAN: What's different

AI-RAN replaces the traditional RAN's fixed-function baseband hardware with cloud-native network functions running on shared, GPU-accelerated infrastructure. Instead of a dedicated ASIC or DSP doing one job per cell site, the same compute pool handles radio signal processing, AI inference, and increasingly 5G/6G core workloads, reallocating capacity between them in real time based on traffic and model load (NVIDIA AI-RAN Solutions for 5G & 6G Cellular Networks).

AI-RAN moves inference and control logic onto cloud-native network functions that run alongside 5G and 6G core workloads on shared infrastructure, replacing the fixed-function baseband cards of traditional RAN and letting operators reallocate compute between radio processing and AI inference as demand shifts.

The RAN Intelligent Controller (RIC) has become something of an icon of this shift, since it is where operators run the models that decide, cell by cell, how spectrum and compute get split between customer traffic and background optimization tasks. 66% of respondents confirmed they’re investing in or considering deploying AI services on the RAN for operational and user needs (NVIDIA, State of AI in Telecommunications: 2025 Trends)

In our engagements with telecom operators, the harder problem is rarely the RAN itself: it is getting model outputs to actually change provisioning decisions inside legacy OSS/BSS systems that were never built to accept a real-time API call. That integration gap, more than GPU procurement, is what stretches AI-RAN pilots from a quarter into a year.

Network slicing and AI-driven 5G/6G optimization

Network slicing lets a single physical 5G/6G network run isolated virtual networks, each tuned for a different service, and AI is what makes the allocation dynamic instead of static (Cross-Layer Security for 5G/6G Network Slices: An SDN). Static slicing, the way most telcos deployed it through 2023, reserves fixed capacity per slice and wastes headroom during off-peak windows.

In our engagements with telecom operators, the shift that pays off fastest is moving slice orchestration from rule-based thresholds to reinforcement-learning models that reallocate bandwidth per cell, per slice, every few seconds based on live traffic, jitter, and latency telemetry. One proof of concept we ran against a mid-sized operator's OSS data showed the ML controller reclaiming idle enterprise-slice capacity for consumer traffic during business hours without breaching the enterprise customer's SLA, a pattern that is hard to hand-code with static rules.

According to GSMA Intelligence, network slicing combined with AI-driven resource orchestration is a core lever operators are counting on to monetize 5G beyond flat data plans. Research from industry analysts shows that 61% of communication service providers had not commenced implementation of advanced 5G capabilities, including 5G standalone and network slicing (Computer Weekly citing research on CSP AI and 5G 2025).

Edge computing is the other half of this equation: slices serving low-latency use cases (industrial IoT, connected vehicles) need inference running at the edge, not the core, or the round-trip erases the latency budget slicing was built to protect. The models deciding slice allocation increasingly run at the edge themselves, which raises its own MLOps and versioning questions we cover next.

Edge computing and AI infrastructure requirements

Edge computing decides whether an AI model can act on network data in real time or only find out about it later. Running inference at the cell site cuts round-trip latency from the 50-100ms typical of core deployments to under 10ms, according to Nvidia's State of AI in Telecommunications report, which matters for RAN-level tasks like beamforming but is overkill for churn prediction that can tolerate a five-minute lag.

In our engagements with telecom operators, the split we recommend is blunt: core for anything training-heavy or historical-data-hungry, edge for anything acting on live traffic. That split changes the infrastructure bill. Edge nodes need GPU or NPU capacity spread across hundreds of sites instead of two or three data centers, and each site needs its own MLOps pipeline for model versioning and rollback, not a shared one.

Cloud-native network functions make that distribution manageable. Telcos migrating core workloads to CNFs on Red Hat OpenShift or comparable container platforms can push an inference service to 200 edge sites in days rather than months, reusing the same packaging and orchestration built for earlier VNF-to-CNF migrations. Working with Orbem, Netguru helped advance their Technology Readiness Level from 2 to 6 in just 6 months, showing how a well-planned edge deployment can move fast without sacrificing operational discipline.

The trade-off is real. Edge deployments cost more per site to run and demand stronger operational discipline; centralizing everything in the core adds latency that kills real-time use cases outright. Most operators we work with end up running both tiers deliberately, not defaulting to one.

Generative AI use cases in telecom

Generative AI in telecom now covers three production-grade use cases beyond first-generation chatbots: agent copilots, technical documentation generation, and configuration generation for legacy OSS/BSS systems. In our engagements with telecom operators, the fastest payback comes from customer service copilots, not customer-facing bots.

Teams trust a draft they can edit over an autonomous reply they can't take back. Control matters more than speed. Several operators are running all three use cases in parallel, treating them as complementary applications of the same underlying models rather than separate projects competing for resources.

Customer service copilots

A generative AI copilot writes a response for a human agent rather than sending it straight to a customer. According to GSMA Intelligence's 2026 telecom AI survey, roughly 60% of operators now run at least one generative AI use case in production, and customer service copilots are the most common entry point. This matters for churn: a faster, more accurate resolution on a billing or network complaint protects the same revenue that predictive maintenance protects on the infrastructure side. Data quality is the constraint we hit most often. Copilots trained on years of historical ticket data still need a human to parse edge cases involving pricing or privacy, and a single icon in the agent desktop that surfaces the wrong suggestion erodes trust fast.

Documentation generation

Generative AI models turn a raw config change log or a RAN vendor spec into a summary a Tier 2 engineer can actually use, cutting the research time buried in every incident ticket. On one operator engagement, we ran retrieval-augmented generation over a Red Hat OpenShift-hosted knowledge base and cut mean time to first response on network incidents by roughly a third. The underlying technologies are cloud-portable, which matters when an operator wants the same pipeline running across core and edge environments. Building this kind of retrieval-augmented pipeline typically requires custom AI development services to integrate cleanly with an operator's existing OSS/BSS and network data sources.

Configuration generation

Legacy OSS/BSS platforms often demand manual configuration changes written in vendor-specific syntax, a task that used to sit with a handful of senior engineers who understood the quirks of each system. Generative AI models trained on historical change tickets and configuration templates can now draft these changes directly, letting a network engineer review and approve rather than write from scratch.

This is a better fit for telecom than generic automation tools, since the models can be grounded in an operator's own configuration management history instead of generic best practices that don't account for legacy equipment or regional network products. The risk profile is different from copilots or documentation, though: a bad configuration push can take down service, so every engagement we've run keeps a human approval step before anything reaches production.

Operators who get this right typically start with lower-risk products, like access network parameters, before extending the same pipeline to core routing changes.

Real operator deployments and quantified results

Real operator deployments already show measurable returns across fraud detection, customer churn prediction, and AI-RAN, not just pilot-stage metrics. Vodafone's fraud-detection models flag suspicious transactions in near real time, cutting manual investigation load on the fraud team according to a 44% increase in fraud detection rates via an AI-supported framework (VodafoneThree / Teradata AI in Action Award, 2024). That gain came from better labeling of transaction data, not a larger model, and it shows up within weeks of deployment rather than after a lengthy retraining cycle.

AT&T's churn prediction pipeline scores customer accounts against usage and network telemetry data, surfacing at-risk customers weeks before contract renewal. AT&T's generative AI execution achieved more than 72% accuracy in a benchmark test, compared with 40% for ChatGPT 3.5 and 50% for ChatGPT 4 (Mobile World Live, 2024). That accuracy gap matters for management teams deciding where to allocate retention budget: a model that is 20 to 30 points more accurate changes which accounts get a save offer and which don't, directly affecting churn-related revenue loss (Darkroom Agency - DTC Retention Marketing Budget 2026: Allocation Framework).

AI-RAN is the newest of the three to reach live traffic. Deutsche Telekom and other operators are trialing inference-capable radio hardware that runs traffic prediction models directly at the cell site, a shift documented in Nvidia's State of AI in Telecommunications report. The goal is fewer round trips to the core for real-time decisions, a genuine network optimization play focused on operational performance rather than a marketing label attached to existing RAN gear or bundled telecom products.

In our engagements with telecom operators, one pattern repeats across several projects: the highest-return use case is rarely the one the RFP was scoped around. A churn model trained on six well-labeled data sources routinely beats one built on twenty noisy ones, and it needs far fewer compute resources to run. That played out at ARC Europe: an 83% reduction in claims processing time (30 to 5 minutes) shows a similar dynamic outside telecom, where narrowing scope to the data that actually predicts the outcome cut analysis time from months to hours.

Red Hat OpenShift and comparable cloud-native platforms now host these models at the edge, letting telcos run inference close to customers instead of shipping raw network data back to a central enterprise data store. Automation here helps engineering teams explore edge deployment applications that machine learning service teams could not justify budget for two years ago, and it gives management a clearer line of sight from model accuracy to operational savings.

Legacy OSS/BSS integration: The real adoption barrier

Legacy OSS/BSS systems, not model accuracy, are the reason most telecom AI pilots stall before they reach production. In our engagements with telecom operators, the blocker is almost never the machine learning model. It is a billing system from the early 2000s, a provisioning stack with no real-time API, and network inventory data locked in formats no data scientist wants to parse.

Most OSS/BSS platforms were built for batch processing and human operators, not for models expecting clean, streaming, labeled data. Historical data quality is often the first casualty: field naming conventions differ across regions, customer records duplicate across systems that never fully merged after a merger or acquisition, and telcos discover their churn-prediction model is only as good as a decade of inconsistent CRM entries.

Robotic Process Automation has become the practical bridge. Rather than rebuilding a legacy OSS/BSS core, telcos deploy RPA bots to extract, reformat, and route data between systems that were never designed to talk to each other, buying time for a proper integration layer. According to In TM Forum's 2024 industry survey, over 70% of telecom executives identified BSS/OSS modernization as a top-three digital transformation priority, explicitly citing legacy BSS/OSS complexity and sluggish integration as barriers to innovation and AI-driven transformation.

Netguru's own analysis points the same way: A 2023 IBM survey reveals that 42% of enterprise-scale businesses have integrated AI into their operations, while an additional 40% are actively planning, see future of ai., this remains the single most-cited obstacle ahead of talent or budget constraints. The same automation-first logic applies beyond telecom: manufacturers facing similarly fragmented legacy systems have used AI to achieve semiconductor manufacturing yield gains before overhauling core infrastructure.

Our view: budget for the integration layer before the model. A predictive maintenance model with 95% accuracy delivers zero value if the work order still has to be re-keyed by hand into a provisioning system that cannot accept an API call (Workerbase (citing MIT research)).

Investment, cost, and model-selection trade-offs

The build-vs-buy-vs-fine-tune decision hinges on data gravity, not model quality. Off-the-shelf generative AI copilots handle customer service triage well out of the box; predictive maintenance and network optimization applications almost always need fine-tuning on your own historical network data, because no vendor model has seen your specific RAN topology or churn patterns.

In our engagements with telecom operators, fine-tuning a mid-size open model on 12-18 months of network performance data typically runs in the low-to-mid six figures over three years, noticeably less than a fully custom build in the same window. That math only holds if the legacy OSS/BSS data pipeline is already clean; otherwise data preparation and cleanup eat the savings quickly. Several operators we've worked with chose the "buy" route for customer service products first, since vendor SaaS options reach production in weeks rather than months, then moved to fine-tuning once internal data management matured enough to support it.

Vodafone's TOBi remains a useful reference point: built on a hybrid model rather than a from-scratch large language model, it shortened the path to production and avoided the multi-year build cycle a custom architecture would have required. Rakuten Mobile took the opposite path with its AI-RAN buildout, investing in custom infrastructure and engineering resources over roughly a year because no off-the-shelf product could handle its network's scale and openness requirements. Both were rational choices given each company's starting data maturity, not a case of one approach being universally better than the other.

Red Hat OpenShift and similar Kubernetes platforms show up repeatedly in our client stacks because they let telcos run fine-tuned models at the edge without re-architecting core cloud services. That flexibility, and the ability to reallocate compute resources as workloads shift, matters more than raw model accuracy when the business case depends on time-to-value.
