Wi-Fi 7 Explained: What Network Engineers Need to Know

In this episode, Andy sits down with Gregory Grimes to unpack the world of Wi-Fi 7 and what it means for network engineers.

If wireless has ever felt like magic compared to the predictability of route/switch, this conversation is for you. Andy and Greg walk through the evolution of wireless networking, from the early days of 802.11 to the latest innovations in Wi-Fi 7, including wider channels, better spectrum use, resource units, and multi-link operation (MLO).

They also explore the real-world question every engineer asks: who actually needs Wi-Fi 7? Is it a game changer for the average home user, or does it really shine in high-density and high-performance environments like classrooms, auditoriums, healthcare, and immersive AR/VR use cases?

Along the way, they translate complex wireless concepts into practical networking language that route/switch engineers can relate to, making this a great episode for anyone who wants to better understand modern wireless without needing a CWNA-level deep dive.

In this episode:

• A quick history of Wi-Fi and the 802.11 standard
• Why wireless feels so different from wired networking
• How contention, collisions, and airtime shape wireless performance
• What OFDMA and resource units actually do
• What makes Wi-Fi 7 different from Wi-Fi 6/6E
• How MLO changes the wireless conversation
• Why deterministic wireless matters
• Where Wi-Fi 7 fits in the enterprise
• When it makes sense to upgrade — and when it doesn’t

The episode also closes with a great reminder that networking is about more than protocols and throughput. Greg shares why the Art of Network Engineering community has mattered to him from the beginning, and why finding your people in this industry makes all the difference.
