How is Edge Computing Enhancing Telecom Speeds for End Users?

Recent forecasts by Omdia suggest a surge in the enterprise edge services market, reaching $116 billion soon and skyrocketing to $245 billion by 2027. Telecoms are uniquely poised to harness it, as this boosts their operations and amplifies their revenue streams. Let’s delve into the transformative power of the edge computing telecom arena.


Understanding telecom latency

The connection between latency and telecom

Latency refers to the time a packet of data travels from the source to the destination. It measures the delay between initiating an action and its perceived effect. In simpler terms, it’s the time interval between when a user’s input is registered and when the desired output is received.

Network latency

Impacts of high latency on telecom services

Excessive delay in telecom services can significantly impair the quality of user interactions. For instance, high latency can result in sluggish website loading times when surfing the internet. Companies leveraging cloud solutions can face hindered productivity and effectiveness because of it. Various elements may contribute to this delay, such as geographical distance, the nature of the connection, bandwidth congestion, or surges in data traffic. This delay is calculated in milliseconds and, when assessing network speeds, is often termed the “ping rate.” Ideally, the lower the ping rate, the better the network responsiveness.

The business demands for low-latency applications

The modern digital world and its products demand low latency. VR applications, which require speedy feedback to be immersive, are notably sensitive to latency issues. Autonomous vehicles, set to be a hallmark of smart cities, rely heavily on real-time data transmission for safe navigation. Health, telemedicine, and remote surgeries demand minimal delays for accurate diagnosis and procedures. Consequently, backing them up with low latency has become a paramount concern for telcos as the digital ecosystem grows more complex and interconnected.


What is edge computing?

Key principles of edge computing

Edge computing operates on a decentralised computing structure, moving the computational processes from remote data centres nearer to where data originates and is utilised. This shift reduces lag time by not relying solely on centralised systems. It is about positioning the data centre functionalities nearer to the data’s birthplace.

Edge Computing Architecture

The difference between edge and traditional cloud computing

Edge computing and cloud computing represent distinct IT paradigms. The first decentralises data processing, bringing it closer to the source, ideal for real-time applications, and often enhances data security by reducing transmission.

Conversely, the second one centralised processing in data centres, primarily serving latency-tolerant tasks such as web apps and storage. While the cloud’s flexible scalability and cost-effectiveness, based on utilised resources, are notable, the edge might necessitate pricier localised equipment. Despite their differences, both play critical roles in the growing digital landscape.

The role of edge computing in reducing latency

Edge computing enables faster data processing right where it’s generated, eliminating the need for lengthy data transfers to the cloud and back. Reducing the lag between data generation and decision-making provides smoother, more responsive operations, which is particularly vital in situations where even a split-second delay can be detrimental.


Peculiarities of telcos edge computing

Edge computing, like IoT devices, processes data closer to its source. Telecom networks, with their cell towers and data centres, are pivotal for this setup. By tapping into these networks, information is processed nearby, reducing the travel distance. This means applications run faster with less delay. Using their vast infrastructures, telcos are embedding edge computing into their systems. Strategically placing servers ensures quick data handling. This evolution isn’t just about speed. It’s paving the way for future innovation.

Edge computing use cases in telecom

vRAN

Operators are increasingly shifting towards virtualizing components of their mobile networks, known as vRAN, realising both cost and adaptability advantages. Key to this transformation, the virtualized RAN hardware mandates intricate processing with minimal delay, necessitating edge servers positioned close to cell towers.

Content caching

Content delivery sees notable enhancements through edge caching. Storing content like music, videos, and web pages near the user optimises delivery by significantly cutting latency. As a strategy, content providers aim to expand CDNs extensively to the edge, ensuring both network adaptability and tailored responses based on user traffic patterns.



Telco edge computing advantages

Reduced latency

By adopting edge computing, telcos can decentralise data collection and processing. It speeds up response times, enabling providers to offer efficient, real-time data services and monitoring solutions.

Improved reliability

The technology enhances the resilience of telco networks. Since edge locations operate autonomously, they can sustain operations even when faced with challenges or unforeseen incidents. This ensures continuous functionality, even if the primary data centre faces issues.

Bandwidth optimization

Edge computing alleviates bandwidth bottlenecks and minimises service disruptions. The risk of potential data breaches is minimised by processing data closer to its origin. This allows companies to maintain robust local processing capabilities, supplying secure and efficient data transfers.



Edge computing architecture

The architecture of an edge computing network in telecom

The architecture of edge computing telecom has been designed to optimise data processing speeds, improve capacity efficiency, and reduce latency, which are crucial for 5G and IoT. A standard edge computing framework consists of three distinct levels:

  • The cloud. Which manages the overall data storage and processing.

  • The edge. Tasked with near-instantaneous data handling.

  • The device. Responsible for initial detection and basic data processing.

Edge Computing Architecture

Critical components of edge computing architecture

Edge servers. These are placed near the edge of the network, close to end users. Their primary role is swiftly processing data without sending it back and forth to a centralised data centre.

Edge data centres. Slightly larger than edge servers, they can handle more extensive processing tasks and store data locally. This reduces the load on the core data centre, ensuring faster content delivery and application responsiveness.

Telecom nodes. In edge computing, telecom nodes like cell towers or base stations can also have integrated computing resources. They can process and analyze data without sending it to a central location. With 5G, these nodes become even more critical, as they can handle massive amounts of information from various devices with minimal delay.

Why is processing data at the edge is important?

Processing data at the edge is not just about speed and latency. It’s about efficiency and intelligence. Time-sensitive applications benefit from the instantaneous processing at the edge. Local processing can mean sensitive data doesn’t have to travel across the network, reducing potential exposure points. Edge computing enables a scalable solution as connected devices expand without overburdening centralised servers.In what spheres the low latency is crucial for telcos?

Augmented and virtual reality applications

Even minor latency in AR/VR can disrupt the experience and even induce discomfort or visual sickness. Low latency guarantees that there is as little delay between what an individual does and the system’s response. It is crucial for a smooth and enjoyable user experience.

IoT and smart cities

Sensors in a smart city, like traffic lights or pollution monitors, need to send and receive data in real-time to adapt to changing conditions. Devices like fire or flood sensors can trigger immediate actions, such as sending alerts or shutting down systems, where even a few seconds of delay can have severe consequences. In smart grids, real-time data on energy consumption can help dynamically adjust power distribution, ensure optimal use, and prevent outages.

Autonomous transportation

Autonomous industrial vehicles are poised to become prevalent in challenging environments or situations that demand remote oversight, such as mines, ports, and manufacturing floors. This scenario highlights the importance of managing fleets effectively and optimising their routes. Controlling vehicles like cranes and trucks from a distance becomes feasible with a latency close to 5 ms.

The future of edge computing low latency

Evolution of low-latency telecom in the coming years

Telecom networks will move further towards a decentralised architecture, placing more emphasis on the edge. This will provide instant data processing.

Automation and AI-driven management will become essential. These tools will play a role in optimising traffic, predicting congestion, and ensuring low latency. Telecom providers will probably offer tiered services based on latency requirements.

Impact on emerging technologies - 5G and beyond

5G is the first telecom standard designed with low latency as a core feature, promising response times as low as 1 millisecond in ideal conditions. Its rollout will amplify the benefits of edge computing. Faster speeds, combined with localised processing, will drastically cut down latency, making real-time applications more viable. The mutually beneficial relationship of low latency telecom, 5G, and edge computing will be vital in coping with this massive data stream without sacrificing quality.
