APAC 5G Field Webinar Series: X-Haul

The development of 5G technology is leading to major changes throughout the entire 5G network. Some of the key benefits of 5G technology include improved Mobile Broadband, which enables faster and more reliable internet connectivity for mobile devices, as well as ultra-reliable low latency communication, which is essential for certain types of applications such as autonomous vehicles and remote surgery.

Another significant advantage of 5G technology is its ability to support massive machine-to-machine communications, which is important for enabling the Internet of Things (IoT) and other advanced technologies.

As a result of these advancements, there is a need to update and modify the entire 5G network, from the radio access network (RAN) to the core network. The VIAVI team has organized a webinar series that will explore the architecture and technology of the emerging X-haul networks, which are a critical part of the 5G network infrastructure.

This webinar series not only delves into the architectural and technological intricacies of 5G networks but also scrutinizes testing methodologies critical to ensuring the seamless implementation of this revolutionary technology. Given the complexity of 5G technology, testing is essential to ensure that the network is functioning as intended and that users are able to take full advantage of the benefits of this technology.

In many ways, 5G networks resemble intricate symphonies, necessitating the harmonious coordination of various components - from fronthaul to backhaul - to deliver a seamless and swift connection. Regular testing ensures that the network performs at its best, providing users with an excellent experience as they navigate the digital landscape. The topics explored in this enlightening webinar series include:

5G Network and X-haul Evolution
Imagine the 5G network as a symphony, where diverse instruments unite to craft a harmonious experience. An integral component is the "x-haul" evolution, which encompasses the integration of fronthaul, midhaul, and backhaul networks - resembling the interconnected highways of a city.

Fronthaul: This is the first leg of the journey. Fronthaul connects the 5G cell towers (also known as small cells) to the central processing units. It's like the short distance between a musician and their conductor in the orchestra. This link needs to be ultra-fast and low-latency to ensure a smooth performance.

Midhaul: Like the middle stretch of a highway, midhaul links various cell towers to aggregation points. This step ensures that signals from multiple small cells come together effectively before continuing their journey.

Backhaul: Here, the aggregated signals travel from aggregation points to the core network, which is like the heart of the city. Backhaul is a long-distance journey that requires high capacity and reliability.

5G RF and Cell Site Testing
Picture a chef preparing a delicious dish – they need to ensure each ingredient is of the highest quality. Similarly, in 5G networks, RF (Radio Frequency) and cell site testing ensure everything works as intended.

RF testing involves checking the radio signals that carry data. This includes assessing signal strength, coverage area, and quality to guarantee a smooth browsing and streaming experience for users.

Cell site testing is like inspecting the chef's kitchen. It involves examining the physical components of cell towers, like antennas and power systems, to ensure they're working correctly. This helps prevent issues and maintain efficient network operation.

Fronthaul / Midhaul / Backhaul Fiber Test
Imagine a relay race – if the baton (data) isn't handed off smoothly between runners (network segments), the team won't succeed. Fiber tests ensure that the "baton exchange" between fronthaul, midhaul, and backhaul networks happens without a hitch.

These tests involve checking the optical fibers that carry data signals. Technicians verify the fiber's quality, capacity, and reliability to make sure data can travel quickly and without loss from one network segment to another.

Fronthaul / Midhaul/ Backhau; Transport and Synchronization Test
In a grand performance, all musicians need to be in sync. Similarly, for smooth 5G operations, different parts of the network must be synchronized like a perfectly timed dance.

Transport and synchronization tests ensure that data reaches its destination at the right time and in the right order. Just as dancers rehearse to stay in sync, these tests involve configuring and verifying network equipment to maintain proper timing and coordination.
