Demands on university networks have changed dramatically. The question is: has your network changed with them?
Technology is helping universities do more than ever before, from hybrid learning and cloud-based research to AI-powered services and smart campuses.
For example, 57% of higher education institutions now consider AI a strategic priority, up from 49% the previous year.
But every new opportunity places greater demands on the network underneath. In fact, AI alone is predicted to triple campus and branch network traffic over the next three years.
It means your network performance, visibility and security can all start to suffer, if your foundational architecture hasn’t evolved.
Here, we outline five signs your network architecture could be ready for a refresh. Plus, some practical recommendations from Adam Husband, Network Architect at Block, to help you build a network that’s ready for whatever comes next.
1. Performance complaints are becoming the norm
Teaching, learning, and research happen without interruption when the network performs as expected. But when performance issues become a regular topic of conversation, it’s often a sign that the network needs attention.
Clear indications can be:
- Students continuously experiencing poor Wi-Fi in lecture theatres.
- Staff struggling with video conferencing.
- Researchers facing significant delays when accessing cloud-hosted resources.
It’s also worth remembering that wireless performance is only as good as the network beneath it. Even the latest Wi-Fi technologies can’t deliver their full potential if the wired infrastructure, switching capacity, or access point placement can’t support today’s demand levels.
Adam’s recommendation:
“Before you assume you need faster Wi-Fi, understand what’s changed. Look at how people are actually using your network today. How many devices are connecting? Where are they concentrated? Which applications matter most? Comparing those demands with your current infrastructure will quickly show where the real bottlenecks are.
“At Block, we start with the data, helping identify whether the issue is wireless coverage, client density, switching capacity, or a network that simply wasn’t designed for today’s campus.”
2. You don’t have a clear view of what’s happening on your network
Troubleshooting gets faster and planning becomes easier when you can see exactly what’s happening across your network.
Modern campuses support thousands of users and devices, from laptops and smartphones to IoT sensors, AV equipment, and specialist research systems. So, understanding what’s happening across the network is important.
Many universities still measure network health using device uptime. While that’s useful, it doesn’t tell you whether students and staff are receiving a good experience. A network can be online while video calls stutter, applications slow down, or users struggle to connect.
If troubleshooting takes longer than it should, or you’re relying on multiple management tools to piece together a fragmented picture of your network health, that’s often a sign your architecture no longer gives your team what it needs.
The best visibility platforms don’t just tell you what’s happening today. They help predict tomorrow’s problems too, highlighting capacity constraints before they affect teaching, learning, or research.
Adam’s recommendation:
“Don’t just measure whether the network is online. Measure whether it’s delivering a great experience. Modern platforms such as Juniper Mist provide rich user experience insights out of the box, while Block’s Axiom platform delivers similar wireless assurance and operational visibility across your environment.
“By monitoring onboarding success, roaming performance, coverage and application experience, you can identify problems before users report them, giving your team more time to improve services rather than firefight recurring issues.”
3. Supporting new digital initiatives feels difficult
Universities are constantly finding new ways to improve teaching, learning, and the student experience. So, a well-designed network should enable innovation, not hold it back.
If every new project requires complex workarounds, extensive redesign, or concerns about capacity, it may be time to reassess whether your network is still fit for purpose.
Adam’s recommendation:
“It’s worth stepping back and looking at the bigger picture here. Over time, networks naturally become more complex as new buildings, technologies, and services are added, creating what we often call a ‘Frankenstein’ network.
“A network refresh gives you the opportunity to simplify your architecture, remove technical debt, and create a consistent foundation that makes it much easier to introduce new technologies, whether that’s AI-enabled learning, smart campus initiatives, or the next generation of wireless.”
4. Security feels increasingly reactive
Protecting users, data, and research has never been more important. And open environments, large user populations, and valuable research data create a complex security landscape.
Thousands of personal devices connect to campus networks every day, alongside university-owned devices, research equipment, and IoT systems. Securing who and what can access your network is becoming just as important as protecting the network itself.
Modernising the network can help your team take a more proactive approach to security, especially if they’re currently spending more time reacting to security concerns rather than mitigating risk.
Adam’s recommendation:
“Security works best when it forms part of the network, not something that’s bolted on afterwards.
Modern network architectures make it easier to adopt Zero Trust principles, segment users and devices, and automate software lifecycle management.
“Through Axiom, Block also helps customers stay on top of published vulnerabilities and software patching, reducing the operational burden while lowering risk. As AI adoption grows, technologies such as secure browser controls and AI policy enforcement can also help prevent sensitive institutional data from being shared with public AI tools.”
5. Your infrastructure is becoming expensive to maintain
Maintaining an ageing network often becomes more demanding over time, especially as hardware approaches end-of-support. You might notice:
- Increasing maintenance requirements.
- Growing energy consumption.
- Specialist knowledge that’s becoming harder to source.
Individually, these challenges can seem manageable. Together, they can consume valuable IT time and budget that could be spent improving the student and staff experience.
Legacy environments can also become heavily dependent on a handful of individuals. Documentation falls out of date, knowledge becomes siloed, and even routine changes carry greater risk because only one or two people fully understand how everything fits together.
The good news is that modern network infrastructure is designed to be far more efficient. Newer switches and wireless access points consume less power, while cloud-managed platforms simplify day-to-day operations and reduce the effort needed to keep your network running at its best.
Adam’s recommendation:
“A network refresh isn’t just about replacing ageing equipment. It’s an opportunity to reduce operational overhead and free your team to focus on more valuable work. Modern platforms support standardised configurations, automation and simpler lifecycle management, making upgrades both faster and more reliable.
“Block’s AutoPatch capability automates software upgrades using proven pre- and post-change checks, reducing manual effort, and minimising the risk of service disruption. Instead of spending time maintaining legacy infrastructure, your digital team can focus on delivering the digital services that support teaching, learning and research.”
Assessing your network
“The strongest networks don’t just support today’s campus,” says Adam. “They create the foundation for whatever comes next, from AI-powered learning and smart campuses to new digital services that improve the student experience.
“If you’re recognising some of the challenges outlined above, now’s a good time to take a fresh look at your network. A few targeted improvements could transform performance, resilience, and visibility, while giving your digital team more time to focus on delivering great digital experiences instead of maintaining the infrastructure behind them.”
