How Recent Spectrum Regulation Changes Could Impact Your 5G Network Deployment

Introduction

If you’re involved in setting up or operating a 5G Mobile Private Network (MPN) for your business, recent updates from Ofcom, the UK’s communications regulator, could influence how you plan, deploy and manage your network. In July 2024, Ofcom released its latest updates to the spectrum regulations – Shared Access Licence Guidance document – https://www.ofcom.org.uk/) building on the previous version from September 2022. These updates focus on how companies can use certain radio frequencies, especially the 3.8-4.2 GHz band, which is key for Private 5G networks. Let’s break down what has changed, how it might affect you in terms of quality, cost, and time, and what you can do to address these impacts.

Synchronisation Requirements
Previously, there was no requirement to synchronise the timing of your network transmissions with others in the 3.8-4.2 GHz band. The new guidelines suggest that while synchronisation is still not required, it might become necessary in the future to avoid interference with other networks. If this requirement comes into effect later, you might need to upgrade or adjust your equipment, which could increase costs and delay your deployment. For example, if you set up your 5G MPN now without this in mind, you might face disruptions later if new rules require you to pause operations and upgrade your system. To avoid this potential issue, consider investing in equipment that can handle synchronisation even if it’s not required yet. This proactive approach can save time and money in the long run, ensuring your network remains operational without major disruptions.

Power Levels
The maximum allowed power for your 5G equipment remains unchanged, meaning there are no new limits to worry about. This is good news because it allows you to maintain your network’s range and performance without making costly adjustments. You can continue using your current setup, knowing it will still be compliant with regulations. To take full advantage of this, make sure your deployment plans maximise the allowed power to provide the best possible service quality and coverage for your network.

Urban vs. Rural Deployment
Medium power licenses, which allow for more powerful network deployments, are still mostly restricted to rural areas. However, the new rules provide more guidance on how to apply for these licenses in urban areas. If you’re located in a city, getting a license might still be challenging, which could delay your deployment or limit your network’s quality. On the other hand, if your business is in a rural location, setting up a powerful 5G network will likely be easier. For urban areas, it’s crucial to gather comprehensive data that supports your application, such as evidence that lower power solutions won’t meet your needs or that your deployment won’t interfere with others. This preparation can increase your chances of getting approval and help you avoid delays.

Dynamic Spectrum Access (DSA)
Ofcom is moving closer to introducing Dynamic Spectrum Access (DSA), which means spectrum could be assigned more flexibly in the future. While this change isn’t happening immediately, it’s important to keep an eye on it. DSA could make spectrum use more efficient, but it might also require future investments in new technology. For instance, if DSA is implemented, you could quickly tap into unused spectrum, boosting your network’s performance. However, to take full advantage of this, you might need to invest in more advanced equipment down the line. Staying informed about DSA developments and considering future-proofing your equipment now could give your network a performance edge when these changes occur.

First-Come, First-Served Spectrum Allocation

The updated guidelines emphasize that spectrum in the 3.8-4.2 GHz band will be allocated on a first-come, first-served basis. This means that those who act quickly will have the best chance of securing the spectrum they need for their 5G networks. If you delay your decision to deploy a 5G MPN, you risk missing out on the optimal spectrum for your needs. Once the spectrum is claimed by others, it may not be available again, which could limit your network’s capacity and quality. For example, if you’re planning a 5G network for a large industrial site, securing the necessary spectrum early is crucial. Waiting too long could result in having to operate on less ideal frequencies, which might affect your network’s performance and scalability. To ensure your network’s long-term quality and growth, it’s essential to prioritise your 5G deployment decisions and secure the spectrum as soon as possible.

What does it all mean

These updates from Ofcom could affect your 5G MPN design, deployment and Operations in several ways. While some changes could increase costs or delay your setup, others might improve network efficiency or make it easier to get the necessary licenses. By staying informed, planning ahead, and taking proactive steps, you can ensure that your 5G network is robust, cost-effective, and future-proof.

Act Fast

Prepare for possible synchronisation requirements by investing in capable equipment now to avoid future disruptions. Maximise your network’s performance by using the current power limits to their full potential. If you’re deploying in a city, carefully plan your application to increase your chances of success. Secure the spectrum you need early to ensure your network’s long-term success, and stay updated on Dynamic Spectrum Access to be ready for future opportunities.
