Capacity needs to be adopted at the edge, though, and I think that’s critically important. And as we have distributed learning, don’t just look at the Wi-Fi access, look at how remote access and security are being covered as well in that context.
On the data center side, obviously, those workloads are very different when it comes to learning, computer science or experimenting. There, I think, most CIOs need to rethink the data center infrastructure as well. Network fabrics such as the one we offer at Extreme Networks allow you to scale in hundred-gig increments in the data center. This becomes really important because institutions can scale the data center very effectively and reuse that same technology on campus to converge student networks, research networks, facilities management — just about everything — in one architecture.
EDTECH: Are there other recommendations you have for future proofing these networks and data centers so they will be easier to scale whenever the next emerging tech is announced?
NISPEL: In terms of scaling for Wi-Fi specifically, the 6GHz band has different propagation characteristics, so you need to redesign your network for 6GHz. But then, when you move to Wi-Fi 6E or 7 or 8, it will not matter because this is the big change that everybody needs to be aware of. Rethinking and redesigning the network for that frequency band, and the coverage that you want to achieve and the experience that you want to deliver, is going to be critical.
If you have a higher ed deployment with as many as 15,000 access points, however, you are going to need an upgrade cycle. What we recommend is to have a specific refresh plan. Don’t let it lapse, so to speak. As you build out, it’s not a one-time thing. You’re continuously building out, and you’re continuously refreshing. So, don’t build up too much technical debt by waiting too long because you think you want to write off your deployment — suddenly, you won’t be able to move anymore, and it will take you five years to upgrade the infrastructure. Specifically on Wi-Fi, it’s driven by the nature of the technology. Every couple of years there’s a new Wi-Fi standard, then new chips coming out, so that is inevitable. Don’t try to fight it. Embrace it, and make it part of the plan.

On the flip side, we’ve also seen a trend in network operations and automation toward the cloud, which gives you a certain level of abstraction where the underlying infrastructure can change but the operating model doesn’t change. And you always have the scale and capacity in the cloud to make those changes along the way. That is certainly something that should be considered. We have seen a push to the cloud in all verticals, including in higher ed, for management and operations specifically.
On the switching side, the same strategy applies. But with our Fabric technology, you can more easily expand capacity without redesigning all the time. I think that’s a clear advantage for us, and we think we have a pretty good architecture in place that gives way more flexibility.
