What Wi-Fi 7 brings
Wi-Fi 7 (802.11be) adds wider 320 MHz channels in the 6 GHz band, more efficient modulation and multi-link operation, which lets a device use more than one band at the same time. In practice, the biggest gains come in dense spaces with modern clients and clean 6 GHz spectrum.
The wired side matters more than ever
A faster radio is wasted if the uplink behind it can’t keep up. Check four things before you buy access points:
- Switch ports
- High-end Wi-Fi 6E and Wi-Fi 7 access points can exceed 1 Gbps. Plan for 2.5 or 5 Gbps multi-gig ports at access point locations.
- Power over Ethernet
- Newer access points often need more power than older ones. Confirm per-port PoE class and total switch power budget, including redundancy.
- Cabling
- Cat6A is the safe choice for new runs to access points. Existing Cat6 often supports 2.5 or 5 Gbps over typical distances, but test before you rely on it.
- Uplinks and core
- More capacity at the edge means more traffic aggregating upstream. Review distribution and core uplinks too.
Designing for 6 GHz
6 GHz signals don’t travel as far or penetrate walls as well as 5 GHz. A design that gave good 5 GHz coverage may leave gaps at 6 GHz, so a predictive model built for 6 GHz — and ideally an on-site validation — is essential.
The upside is space: 6 GHz offers many more clean channels, which means less co-channel interference in dense deployments and more room to use wider channels where they help.
Clients decide the outcome
Only devices that support 6 GHz and Wi-Fi 7 features benefit from them. Inventory your laptops, phones and specialist devices; many organizations will run mixed fleets for years. Design SSIDs and security (WPA3 is required in 6 GHz) so older devices keep working while newer ones get the gains.
