Wi-Fi 7 brings 320MHz channels, 4K-QAM and multi-link operation. Here's what changes and what doesn't.
· 3 min read
Key takeaways
- Wi-Fi 7 adds multi-link operation for lower latency.
- 320MHz channels need the 6GHz band.
- Most IoT devices will stay on Wi-Fi 4–6 for years.
What's new
Multi-link operation (MLO) lets a device use several bands at once, cutting lag spikes. 4K-QAM packs more data into each signal.
Do you need it now?
Streaming gadgets like a Wi-Fi 6 pocket projector already stream 1080p smoothly. Wi-Fi 7 matters most for crowded homes and heavy downloads.
IoT stays simple
Maker boards favour cheap, low-power Wi-Fi 4 radios; an ESP32-S3 connects fine to a Wi-Fi 7 router in compatibility mode.
