Does it Matter What AP You Buy (2025)? | Wes Purvis | WLPC Phoenix 2025

Is there still a meaningful difference between 2x2 and 4x4 APs in today’s networks? Do client trends and modern use cases change how we should think about AP selection in 2025? Wes Purvis revisits his popular 2018 WLPC talk with fresh data, RF math, and real-world insight — exploring whether AP specs really impact performance today. This session dives deep into spatial streams, MIMO gain, throughput analysis, retry rates, antenna design, and client behavior trends across the Mist cloud environment. Whether you’re evaluating your next AP deployment or just curious how modern Wi-Fi has evolved, this talk offers data-backed answers and field-proven takeaways. 🎯 Key Takeaways: Why 3x3 is gone and 2x2 vs 4x4 matters more than ever What data rates you can really expect in 2025 from modern clients Real-world Mist cloud data comparing 2x2 vs 4x4 APs in RSSI, throughput & retries How MIMO and antenna design impact performance AP tier differences: radios, memory, Ethernet, directional antennas, and beyond Practical guidance on deploying dual 5 GHz and 6 GHz radios 📑 Presentation page: 👉 https://www.thewlpc.com/presentations... ⏱ Chapters 00:00 – Intro & Revisiting the 2018 Talk 01:20 – What's Changed in Wi-Fi Since 2018 01:58 – The Fall of 3x3 & Rise of 2x2/4x4 03:04 – Client Capabilities in 2025 03:50 – Data Rate Comparison: Then vs Now 05:24 – Modulation & Channel Width Efficiency 06:45 – Real-World Channel Width Usage (Mist Cloud) 08:45 – Intro to 2x2 vs 4x4 AP Architecture 10:14 – MIMO Gain & Transmit Power Calculations 12:00 – Does the Math Match Reality?
