Edge AI – Implementation of artificial intelligence on edge devices

In an era of digital transformation, where every device can be connected to the internet, there is a need to process data closer to its source. Edge AI addresses this need by offering innovative solutions that are changing the way businesses operate. The article provides a comprehensive look at the technology, its applications and implementation challenges.

Edge AI means implementing artificial intelligence algorithms directly on edge devices – close to where the data is generated. This is a fundamental paradigm shift from the traditional model, where data is sent to centralized data centers or the cloud for processing. In Edge AI, inference (inference) processes take place locally, on the device itself.

The technology is revolutionizing data processing by drastically reducing latency. When decisions are made locally, without the need to communicate with remote servers, system response times are reduced from hundreds of milliseconds to single ones. This is crucial in applications that require real-time response, such as autonomous vehicles and security monitoring systems.

Another revolutionary aspect of Edge AI is the reduction of dependence on a fixed internet connection. Edge devices using this technology can operate independently, even in areas with limited connectivity, opening up new opportunities for Industry 4.0, smart cities and IoT applications in hard-to-reach locations.

Key measurable benefits of Edge AI

• Latency reduction: from 100-500ms (cloud) to 5-20ms (edge)
• Reduce bandwidth usage: 60-95% less data sent to the cloud
• Increased availability: functioning with connectivity <50% of the time
• Power autonomy: 30-70% longer battery life for mobile devices

How is Edge AI different from standard edge computing?

Edge computing and Edge AI, while closely related, are not identical concepts. Edge computing is a concept of processing data closer to its source, focusing on the infrastructure and architecture of the network. It encompasses a range of technologies and approaches that move computing power from data centers to the periphery of the network.

Edge AI goes a step further, focusing on implementing specific artificial intelligence and machine learning algorithms on these edge devices. This not only moves data processing, but also autonomous decision-making based on advanced AI models. While standard edge computing can perform simple operations on data, Edge AI enables complex analytics, pattern recognition or event prediction directly on the device.

A fundamental difference is also the way the systems are programmed and managed. Edge AI requires a specialized approach to optimizing models for the limited resources of edge devices – reducing the size of models, quantizing parameters or using specialized hardware gas pedals, which is not necessary in standard edge computing.

How does Edge AI differ from traditional IoT computing?

Traditional data processing in the Internet of Things (IoT) ecosystem is based on a model in which devices act as simple sensors and data collection points. Most IoT devices collect information and send it to the cloud or central servers, where it is only analyzed and processed. This architecture, while proven, carries limitations in terms of speed of operation and bandwidth efficiency.

Edge AI dramatically changes this model, transforming IoT devices from passive data collectors into intelligent decision-making nodes. Devices equipped with Edge AI can autonomously interpret collected data, identify anomalies, classify events and make autonomous decisions without the need for constant communication with the cloud.

A major difference also lies in data privacy management. In the traditional IoT model, all raw data is sent to the cloud, raising privacy concerns. Edge AI allows the initial analysis to be performed locally, sending only aggregated results or alerts about detected events to the cloud, significantly reducing the amount of sensitive information leaving the device.

Why is Edge AI a better solution than cloud computing for some applications?

Cloud computing has revolutionized modern computing, offering virtually unlimited computing power on demand. But in some applications, Edge AI outperforms cloud solutions in a number of ways. A key factor is latency – the delay that occurs between a request and a response. For applications that require millisecond responses, such as industrial machine control or autonomous vehicles, even the fastest connection to the cloud can be too slow.

Another important aspect is the reliability of operation. Cloud-only systems depend on a constant, high-quality Internet connection. In locations with limited connectivity, such as oil rigs, remote manufacturing plants or rural areas, Edge AI ensures that critical systems continue to operate regardless of the state of the connection.

The economic aspect also speaks in favor of Edge AI in specific scenarios. Transferring huge amounts of raw data to the cloud, especially from thousands of IoT devices, generates significant transfer and storage costs. Edge AI, by locally analyzing and filtering the data, allows only relevant information to be transferred, reducing the operational costs associated with cloud infrastructure.

Cost comparison: Edge AI vs. Cloud

Video surveillance system (100 cameras, 1 month):

• Cloud: 25TB data transfer = $500-1000 + Processing = $1200-2500
• Edge AI: Transmission of 2TB alerts = $40-100 + Local processing = $300-600
• Savings: 75-85% of costs per month

Predictive maintenance system (50 machines):

• Cloud: $20-35 per machine per month
• Edge AI: $7-15 per machine per month after initial cost
• Return on investment: 8-14 months

In what industries is Edge AI already finding practical application?

Edge AI finds practical application in the manufacturing industry, where predictive maintenance algorithms analyze machine sensor data in real time, detecting potential failures before they affect production. Smart cameras equipped with Edge AI capabilities monitor product quality directly on the production line, eliminating defective pieces without human intervention.

In the healthcare sector, medical devices with Edge AI make it possible to monitor patients without constantly sending sensitive medical data to the cloud. Portable diagnostic devices can analyze biomedical data locally, immediately detecting life-threatening conditions and alerting medical personnel. This autonomy is particularly valuable in regions with limited access to specialists.

Smart cities and transportation are other areas of intense Edge AI deployment. Smart traffic signals analyze traffic flow in real time, dynamically adapting to the current traffic situation. City surveillance systems use local video processing to identify dangerous situations without transmitting a continuous stream of footage, significantly reducing network infrastructure requirements.

How does Edge AI improve the end-user experience?

Edge AI fundamentally changes users’ interactions with technology, offering instant response to voice commands or gestures. Virtual assistants implementing speech recognition directly on the device eliminate delays typical of cloud-based solutions. The user receives a response in a fraction of a second, making the interaction more natural and fluid.

Augmented reality (AR) applications are gaining a new dimension with Edge AI. Local image processing allows virtual elements to be accurately superimposed on the real world with minimal latency. Games, educational applications or tools supporting work activities can now react to changes in the environment in real time, significantly increasing immersion and usability.

Personalizing the experience is another area where Edge AI brings significant value. Machine learning algorithms on users’ devices can continuously analyze usage patterns, adjusting the interface, content or recommendations without having to send behavioral data to external servers. This improves not only system responsiveness, but also privacy, which is increasingly a key decision factor for informed users.

How does Edge AI affect the energy efficiency of devices?

Edge AI paradoxically can lead to significant energy savings, despite the additional computational load on end devices. A key mechanism is the elimination of continuous data transmission, which is one of the most energy-intensive aspects of IoT devices. Local data processing requires short-term peaks in computing power, but eliminates the constant power consumption associated with network communications.

Modern hardware architectures, such as dedicated neural processing units (NPUs) and energy-efficient signal processors (DSPs), are designed for maximum energy efficiency when performing AI tasks. These technologies allow complex operations to be performed with minimal power consumption, enabling Edge AI to be implemented even in battery-powered devices.

Intelligent power management is another aspect where Edge AI shows an advantage. Machine learning algorithms can analyze usage patterns and dynamically adjust power consumption according to current needs, activating more powerful components only when they are actually needed. As a result, devices with Edge AI can extend battery life by up to 30-50% compared to traditional implementations.

Comparison of energy consumption for typical AI tasks

Image classification (ResNet-50):

• Cloud: 4.2kWh (transmission + processing)
• Edge: 0.7kWh (local processing)
• Reduction: 83%

Audio stream analysis (keyword detection):

• Cloud: 1.8kWh per day
• Edge: 0.25kWh per day
• Reduction: 86%

Industrial monitoring (50 sensors):

• Cloud: 3.5kWh per day
• Edge: 0.8kWh per day
• Reduction: 77%

What cyber security benefits does Edge AI offer?

Edge AI introduces a new security paradigm, significantly reducing the attack surface by limiting the amount of data leaving the device. In the traditional model, raw data is sent to the cloud, creating multiple vectors of potential breaches. Edge AI enables local analysis and transmission of only metadata or inference results, protecting sensitive information from interception during transmission.

Decentralized processing is a natural barrier against large-scale attacks. While a breach of a central cloud can compromise data from thousands of devices, a successful attack on an Edge AI system only affects a single device. This atomization of risk represents a major shift in the approach to security architecture, especially in critical infrastructures.

The autonomy of Edge AI systems allows the implementation of advanced anomaly detection mechanisms directly on devices. These algorithms can identify unusual behavioral patterns suggesting attempted attacks, such as unauthorized access or malicious software modifications. Importantly, these systems can respond to threats locally, even in the absence of a connection to a central security system.

What are the key challenges in implementing artificial intelligence on edge devices?

The fundamental challenge of Edge AI remains hardware limitations. Advanced deep learning models require significant computing and memory resources, while edge devices often have limited CPU power, RAM and battery capacity. This forces trade-offs between model accuracy and efficiency, which can limit applications requiring the highest precision.

Fragmentation of the device ecosystem poses another significant challenge. The edge device market is characterized by a huge variety of hardware platforms, operating systems and technical capabilities. Creating Edge AI solutions that work effectively on such diverse devices requires a great deal of testing and optimization for specific platforms.

One of the most challenging aspects is updating and managing AI models in a distributed environment. As models evolve and are improved, there is a need to update them on hundreds or thousands of devices in the field. Designing effective mechanisms for securely distributing updates that do not disrupt devices or create new security vulnerabilities remains a significant operational challenge.

How to choose the right hardware for Edge AI implementation?

Once the basic challenges of Edge AI are understood, a key step is to select the right hardware platform that balances performance requirements with energy and cost constraints. The process of selecting the optimal hardware requires a systematic approach that takes into account the specifics of the application.

Choosing the right hardware for Edge AI implementation should start with a thorough analysis of the application requirements. Key parameters include the complexity of the AI models to be used, the required inference frequency and power consumption constraints. Applications using real-time image recognition will require much more powerful components than systems analyzing sensor data at a lower frequency.

Dedicated AI gas pedals are now the standard in advanced Edge AI implementations. NPUs (Neural Processing Unit), VPUs (Vision Processing Unit) or FPGAs offer many times higher energy efficiency for machine learning tasks compared to standard CPUs. Modern SoCs (System on Chip) often integrate these gas pedals directly into the CPU, creating complete solutions for Edge AI.

The operating environment of the device is also an important consideration. Industrial or outdoor implementations require components with increased resistance to temperature, vibration or humidity. Battery-powered consumer devices, on the other hand, prioritize miniaturization and energy efficiency. Hardware selection must take these specific operating conditions into account to ensure system reliability and longevity.

PRACTICAL TIPS FOR CHOOSING EQUIPMENT FOR EDGE AI

✓ For image recognition: min. 2 TOPS NPU performance, 4GB RAM ✓ For audio analysis: DSP with 500MHz+ and dedicated audio gas pedals ✓ For industrial applications: choose chips with 7+ years availability guarantee ✓ Real-world testing – often 2-3x higher than spec ✓ Diagnostic tools (JTAG, I2C) necessary for field debugging ✓ Plan for 30-50% spare computing power for future model updates

How do you optimize AI models for resource-constrained edge devices?

Optimizing AI models for edge devices requires a multi-faceted approach, starting at the architecture design stage. Lighter variants of popular neural networks, such as MobileNet or EfficientNet, have been specifically designed with mobile devices in mind, offering significantly lower resource requirements with an acceptable reduction in accuracy. Choosing the right underlying architecture is the foundation of effective Edge AI.

Parameter quantization is one of the most effective techniques for reducing model size. It involves converting model parameters from precision floating-point numbers (float32) to lower precision representations (int8/int16). This transformation can reduce model size by up to four times with minimal impact on accuracy. Modern AI frameworks offer advanced tools for quantization with predictive quality.

Pruning and compression are complementary optimization methods that remove the least important connections in a neural network and compress the remaining parameters. Studies show that up to 80-90% of the parameters of some networks can be removed without significantly affecting accuracy. These techniques, combined with knowledge distillation, where a smaller model “learns” from a larger one, form the foundation of modern Edge AI optimization methods.

Example of TensorFlow model optimization process for Edge AI

Step 1: Select the base model

• Initial model: MobileNetV2 (14MB, 71% Top-1 accuracy)

Step 2: Trimming (pruning) and training with regularization

• Removal of the 40% least significant weights
• Dotraining: 5 epochs with L1 regularization
• Result: 8.2MB, 70.2% accuracy

Step 3: Post-training quantification

• Conversion from float32 to int8
• Calibration on a representative dataset (1000 samples)
• Result: 2.1MB, 69.5% accuracy

Step 4: Benchmarking on the target device

• Original model: 240ms inference, 190mW power consumption
• After optimization: 45ms inference, 70mW power consumption
• Improvement: 5.3x faster inference, 2.7x lower power consumption

How do you integrate Edge AI into your existing IT infrastructure?

Integrating Edge AI with existing IT infrastructure requires careful architecture planning, taking into account both the capabilities of edge devices and existing central systems. A key element is designing an efficient data flow between the edge layer and the enterprise’s central systems. This requires defining which data is processed locally and which should be sent for further analysis.

Communication standards play a fundamental role in Edge AI integration. Protocols such as MQTT, CoAP and OPC UA have been optimized for IoT communications and can effectively connect edge devices to the central infrastructure. It is important to ensure that the selected protocols support security mechanisms appropriate to the sensitivity of the data being processed.

Device management is one of the most complex aspects of integration. IoT Edge platforms, such as Azure IoT Edge, AWS IoT Greengrass and Google Cloud IoT Edge, offer comprehensive tools to remotely deploy, monitor and update AI models on edge devices. These solutions also provide integration with existing monitoring and IT asset management systems, enabling unified management of the entire infrastructure.

Can Edge AI work with hybrid cloud?

The integration of Edge AI with hybrid cloud creates a synergy that leverages the strengths of both approaches. In this model, local devices perform low-latency tasks, while complex calculations and long-term trend analysis take place in the cloud environment.

Edge AI and hybrid cloud are natural complements, creating a multi-tier processing architecture. In the hybrid model, edge devices with Edge AI perform initial data analysis and filtering, making autonomous decisions in cases that require immediate response. At the same time, they send aggregated data or particularly complex problems to the cloud for processing, taking advantage of its greater computing power.

Model training and evolution is an excellent example of Edge AI’s symbiosis with the hybrid cloud. While inference (inference) takes place on edge devices, the cloud can be used to train and refine models based on data collected from multiple devices. The updated models are then distributed back to the devices, creating a self-learning ecosystem.

Operational flexibility is another advantage of the hybrid approach. It allows dynamic load adjustment between edge and cloud computing depending on current conditions – link availability, device load or business priorities. In emergency situations, when cloud connectivity is limited, Edge AI ensures continuity of critical functions, while more accurate cloud processing is possible once connectivity is restored.

Practical model of Edge AI collaboration with hybrid cloud

On the edge device:

• Instant real-time data analysis
• Local time-critical decision-making
• Pre-filtering and aggregation of data
• Buffering of data during communication outages (up to 7 days)

In the cloud:

• Long-term historical analysis and trend detection
• Advanced analytics on aggregated data
• Training and updating models
• Management and orchestration of the entire fleet of equipment

Data flow:

• Prioritization of critical events with limited connectivity
• Intelligent bidirectional synchronization mechanisms
• Differential model update (only changed parameters)

Is Edge AI implementation cost-effective for small and medium-sized enterprises?

Edge AI implementation is becoming increasingly accessible to small and medium-sized enterprises thanks to the development of off-the-shelf solutions and platforms. Modern low-code tools and Edge AI as a Service (AIaaS) platforms significantly lower the entry threshold, eliminating the need for machine learning expertise. SMEs can use off-the-shelf models, adapting them to their needs with minimal development effort.

Return on investment (ROI) analysis for Edge AI should take into account not only direct hardware and software costs, but also operational savings. Reducing data transfer costs, extending equipment life through effective power management, and reducing equipment downtime through predictive maintenance can yield significant savings that often exceed the initial outlay in as little as 12-18 months.

A phased approach is the optimal strategy for SMEs considering implementing Edge AI. Starting with pilot projects in areas with the highest potential for return, such as optimizing manufacturing processes or reducing energy consumption, allows the benefits to be verified with limited risk. The success of these initiatives can then justify broader implementation across the organization.

What are the most common mistakes companies make when implementing Edge AI?

One of the most common mistakes in implementing Edge AI is insufficient analysis of use cases and the selection of inappropriate scenarios for the technology. Not every analytics task requires Edge AI – in some cases, traditional cloud computing can be more cost-effective and efficient. The key is to identify processes where latency, autonomy or data privacy are actually critical, rather than implementing Edge AI as a trendy solution without a business case.

Neglecting the security aspect is another serious mistake. Edge devices often operate in physically unsecured locations, making them vulnerable to tampering. Inadequate communication security, failure to encrypt stored data, or failure to use a secure boot-up process can lead to system compromise. Security should be an integral part of the Edge AI architecture from the beginning of the project, not an add-on implemented after the fact.

Failure to consider operational constraints is a third common mistake. Companies often design Edge AI systems without due consideration of the realities of the environment in which they will operate – connectivity limitations, power fluctuations or extreme conditions. This also applies to maintenance and upgrade aspects – systems designed without thinking about easy maintenance can generate high operating costs and become quickly obsolete.

How do you ensure the scalability of Edge AI solutions as your business grows?

Edge AI solutions must evolve as the organization grows, which requires a forward-looking approach from the design stage. Key strategies to ensure these systems scale effectively are discussed below.

Modular design is the foundation of Edge AI’s scalable solutions. An architecture based on loosely coupled components that communicate through standard interfaces allows new devices and functionality to be easily added without rebuilding the entire system. This approach allows Edge AI to expand its reach incrementally as the organization grows, maintaining consistency across the ecosystem.

Standardization of hardware and software platforms is critical for effective scalability. Choosing standardized platforms for similar categories of edge devices simplifies fleet management, software upgrades and integration with central systems. Reducing the number of different platforms reduces operational complexity and lowers total cost of ownership (TCO) as the number of devices increases.

Implementing a central management system for edge devices is essential for larger scale deployments. Platforms such as Azure IoT Hub or AWS IoT Core enable remote deployment of AI models, device health monitoring, update management and access control from a single point. These management systems should be implemented from the beginning, even for small pilot projects, to ensure smooth scaling in the future.

Edge AI scaling strategy – a phased approach

Phase 1 (1-50 devices):

• Choosing a unified hardware and software platform
• Implementation of a central management system
• Manual monitoring and troubleshooting
• Documentation of installation and configuration processes

Phase 2 (50-500 devices):

• Automation of deployments and upgrades
• Grouping devices by location/function
• Implementation of advanced monitoring
• Network bandwidth optimization

Phase 3 (500+ devices):

• Hierarchical management structure with local hubs
• Automatic reconfiguration and self-healing
• Predictive resource management
• Flexible scaling based on microservices

How to manage data in Edge AI-based systems?

Data management is the foundation of effective Edge AI systems and requires a comprehensive approach that combines local processing with a central repository.

Managing data in Edge AI systems requires a thoughtful strategy for data flow, processing and storage. A key principle is to determine which data should be analyzed locally, which sent to the cloud, and which can be safely discarded. This categorization should take into account the business value of the data, its sensitivity and processing latency requirements.

Effective caching and synchronization are important mechanisms for ensuring data integrity in an Edge AI environment. Edge devices should have the ability to store data locally in the event of a loss of connectivity, and then intelligently synchronize once connectivity is restored, prioritizing critical information. This requires the implementation of advanced queue management algorithms and conflict resolution strategies.

Data retention policies must be tailored to the specifics of edge devices, which often have limited storage space. Automatic cleaning, compression and archiving mechanisms should be implemented to prevent memory overflow while preserving relevant historical data. Special attention should be paid to compliance with data storage regulations such as RODO and CCPA.

A practical model for data management in Edge AI

Data categorization:

• Critical data: processed locally, transmitted immediately
• Analytical data: aggregated locally, transmitted in batches
• Temporary data: used locally, not transmitted
• Diagnostic data: stored locally, transmitted on demand

Caching strategies:

• Circular buffer: for constant volume data streams
• Priority queue: for events of different importance
• Time-based expiration: automatic removal of outdated data

Retention policies:

• Raw data: 2-7 days locally (depending on capacity)
• Aggregated data: 30-90 days locally
• Metadata and alerts: stored permanently
• System logs: rotation every 14 days, archiving of critical events

What skills are key for teams implementing Edge AI?

Effective implementation of Edge AI solutions requires a diverse set of skills beyond the traditional competencies of IT or data science teams. Fundamental knowledge is a deep understanding of techniques for optimizing machine learning models for resource-constrained devices. Specialists should be proficient in quantization techniques, model pruning and specific neural network architectures designed for edge devices.

Knowledge of embedded systems programming is an important complement to AI-related competencies. Programmers need to understand the specifics of working with limited resources, optimizing for energy efficiency and the low-level aspects of interacting with peripherals. Languages such as C++, Rust or specialized frameworks for edge devices are often essential for optimal performance.

Experience in designing and implementing IoT solutions completes the competency profile of the Edge AI team. This includes knowledge of communication protocols used in IoT, mechanisms for managing distributed devices, and designing systems that are resilient to connectivity failures. Particularly valuable are the skills to integrate edge systems with existing central and cloud infrastructure, creating a cohesive ecosystem.

What tools and frameworks make Edge AI implementation easier?

Choosing the right tools and frameworks is crucial for effective Edge AI implementation. Below is an overview of the most important solutions, with a practical comparison of their strengths and weaknesses.

TensorFlow Lite and PyTorch Mobile are currently the dominant frameworks for Edge AI, offering advanced tools for optimizing machine learning models for resource-constrained devices. TensorFlow Lite stands out for its extensive ecosystem of model quantization and pruning tools, while PyTorch Mobile offers a more flexible workflow and easier integration with existing PyTorch models.

Dedicated Edge AI platforms, such as Google Coral, NVIDIA Jetson and Intel OpenVINO, combine specialized hardware with optimized software to provide a powerful environment for deploying machine learning models. These solutions offer both hardware acceleration and dedicated libraries tailored to specific architectures, significantly simplifying the deployment process while ensuring high performance.

Edge device management tools such as Azure IoT Edge, AWS Greengrass and Kubernetes at the Edge (Edge K8s) enable efficient deployment, monitoring and updating of Edge AI solutions at enterprise scale. These platforms support the entire lifecycle of Edge AI applications, from initial deployment to continuous model updates, ensuring operational reliability and security in a heterogeneous device environment.

How is Edge AI changing the approach to software development?

Edge AI fundamentally transforms the traditional software development model, forcing an “AI-first” approach right from the architecture design stage. Developers need to consider the processing specifics of machine learning models on edge devices from the very beginning of the development process, rather than adding AI functionality as an additional layer to existing applications. This requires close collaboration between AI specialists, embedded systems developers and IoT engineers.

Testing and validation of Edge AI applications require new methodologies beyond traditional software testing. In addition to standard functional and performance testing, it is necessary to test the accuracy of AI models in real-world conditions, their behavior in the event of hardware failure or connectivity degradation, and energy efficiency. Environmental simulators are becoming an integral part of the development process, enabling testing in a variety of scenarios without physical deployment.

The DevOps approach is evolving into MLOps (Machine Learning Operations), which integrates the lifecycle of machine learning models into software development and deployment processes. MLOps for Edge AI includes not only continuous code integration and deployment, but also model training automation, optimization for edge devices, and secure distribution to distributed devices. This convergence requires new tools, processes and team competencies.

What legal and ethical challenges are involved in implementing Edge AI?

Implementing Edge AI, despite its numerous technical and business benefits, comes with significant legal and ethical challenges that organizations must responsibly address.

Data privacy is a fundamental ethical challenge in the context of Edge AI. While on-device processing has the potential to enhance privacy by limiting data transfer, the collection and analysis of data from a user’s environment itself raises important questions about consent and transparency. Particularly in the case of systems using cameras or microphones, the line between improving user experience and surveillance can be subtle.

Liability for autonomous decisions made by Edge AI systems is a complex legal issue. When an edge device makes decisions without human oversight, the question of liability in case of errors or damage arises. This is particularly relevant in critical applications, such as autonomous vehicles or medical devices, where regulations often have not kept pace with technological developments.

Accessibility and digital exclusion are important ethical considerations for Edge AI deployments. The technology has the potential to exacerbate existing inequalities if advanced AI features are only available to the newest and most expensive devices. Designing inclusive Edge AI solutions that also work on lower-end devices becomes not only a technical challenge, but also an ethical obligation for responsible organizations.

What are the predictions for the development of Edge AI over the next 5 years?

The rapidly growing Edge AI market is facing disruptive changes that will fundamentally transform how the technology is deployed and used in the coming years.

Miniaturization and specialization of hardware for Edge AI will continue in the coming years, leading to the emergence of AI microchips optimized for specific applications. Semiconductor manufacturers are investing heavily in the development of energy-efficient NPUs, which will be integrated into an increasing number of everyday devices. This hardware evolution will open up new opportunities for Edge AI applications in sectors where resource constraints have previously been a barrier to entry.

Federated Learning will become the standard approach for training models in Edge AI ecosystems. This methodology allows distributed edge devices to jointly learn a global model without centrally collecting training data. Devices train local models on their own data and then send only parameter updates to the coordinating server. The technique addresses concerns about privacy and data transfer efficiency while enabling continuous model improvement.

The integration of Edge AI with 5G technologies and future 6G networks will lead to new paradigms of distributed computing. Low-latency, high-throughput communication will enable dynamic load balancing between edge devices and edge servers (edge servers) located in the telecommunications infrastructure. This synergy of technologies will enable more seamless and flexible processing, tailored to current needs and available resources.

Realistic limitations and challenges of Edge AI

Technical limitations:
