Roaming Wars: How Different Devices Roam | Jerry Olla | WLPC Phoenix 2025

Ever wondered how modern Wi-Fi clients behave across different bands in real-world roaming scenarios? In this highly practical and data-driven session, Jerry Olla dives into roaming behavior across a wide range of 6 GHz-capable devices, including Windows laptops, Android phones, iPhones, and Wi-Fi 7 clients. From sticky clients to band preference quirks and the impact of MLO, this session is packed with insights to help you fine-tune your wireless design and client strategy. Jerry explores how client devices choose between 2.4, 5, and 6 GHz, whether wider channels influence roaming decisions, and how technologies like 802.11k and MLO (Multi-Link Operation) affect behavior. Using over 1,000 real-world roaming events and automated testing tools, he presents data-backed conclusions and offers practical design guidance for today's complex roaming environments. Key Takeaways: Real-world roaming behavior across dozens of 6 GHz-capable devices How channel width, PSC vs. non-PSC, and band preference affect client decisions The impact of enabling 802.11k on sticky clients (spoiler: it helps!) How Wi-Fi 7 MLO changes roaming patterns and lowers roam frequency Recommendations for using 2.4 GHz, PSC channels, and mixing channel widths Tools used: N Oversight (iOS/macOS), LS-WiFi (Windows), Android system logs, Nomad + Airtool 2 📍 Presentation page + slides : 👉 https://www.thewlpc.com/presentations... ⏱️ Chapters 00:00 – Intro & Roaming Wars Overview 00:39 – Roaming Behavior: What Inspired This Talk 01:16 – Devices Tested: Laptops, Phones, and Wi-Fi 6E/7 Clients 02:03 – AX210 Challenges: Inconsistent 6 GHz Support 03:00 – Default Configurations: Why They Matter in Roaming Tests 03:50 – Manual vs. Automated Roaming Test Methods 05:06 – Automated Power Cycling for Repeatable Testing 06:02 – Test Setup: Balanced RSSI and 1,000+ Roaming Events Captured 06:48 – Baseline: Do Clients Prefer 6 GHz By Default? 08:45 – Impact of Channel Width: Bumping 6 GHz to 80 MHz 09:58 – 5 GHz at 40 MHz: Influence on iPhone Roaming 11:00 – Dual Band Testing: 2.4 vs 5/6 GHz Preferences 12:27 – PSC vs. Non-PSC Channels: Real-World Roaming Impact 13:21 – Testing 802.11k: Does It Help Clients Roam Better? 15:03 – Side-by-Side Results: 802.11k On vs Off 16:05 – Wi-Fi 7 + MLO: What Happens to Roaming Frequency? 17:30 – How MLO Reduces Panic Roaming in Wi-Fi 7 Clients 19:04 – 6 GHz Only APs + FILS Discovery: What Could Go Wrong? 20:32 – Design Considerations: RSSI, Wider Channels, PSC Use 22:45 – Channel Width Limitations & 40 MHz Gotchas 24:00 – Mixing Channel Widths & Sticky Client Risks 25:00 – Final Roaming Tips: 802.11k, 2.4 GHz, Client-Specific Behavior 26:00 – Tools Used for Roaming Analysis 29:00 – Wrap-Up & GitHub Repo with Full Test Results Keywords & Hashtags: Wi-Fi Roaming | Wi-Fi 6E | Wi-Fi 7 | MLO | 802.11k | 6 GHz | Sticky Clients | Wireless Design | Mobility | WLPC 2025 | Roaming Testing Tools | Airtool 2 | Nomad | LS-WiFi | Network Design | PSC Channels #WLPC #WiFiRoaming #WirelessLAN #WiFi6E #WiFi7 #MLO #StickyClients #80211k #WirelessTesting ⚠️ This video description was generated with the help of AI.
