Frequently asked questions
Should I upgrade my office to WiFi 6 or WiFi 6E?
WiFi 6 (802.11ax) is the recommended baseline for any new enterprise deployment or refresh. It delivers meaningful improvements over WiFi 5 in high-density environments due to OFDMA and improved MU-MIMO, which matter most in meeting rooms and open offices with many concurrent devices. WiFi 6E adds the uncongested 6 GHz band — worthwhile for organizations doing heavy video production, low-latency trading, or deploying many devices in a small space. The main limitation of 6E is that clients must also support 6 GHz, which most devices purchased before 2022 do not.
What is WiFi 7 and when should businesses deploy it?
WiFi 7 (802.11be) was finalized in 2024 and introduces Multi-Link Operation (MLO), 320 MHz channels, and 4096-QAM — delivering theoretical speeds up to 46 Gbps. For most businesses, WiFi 7 infrastructure is appropriate for greenfield buildouts that need to be future-proof for 7–10 years, or for specific high-demand environments like broadcast studios or dense trading floors. As of mid-2025, client device support is growing but not yet ubiquitous. WiFi 6E remains the mature enterprise choice for most deployments.
