Wi-Fi 7 is being widely promoted by manufacturers and the industry press – and for good reason. But beyond the headlines, what are the real benefits, and what should organisations be thinking about when it comes to adoption?
At PTS, we explore these questions from the perspectives that matter most: client needs, technical realities, and broader market trends.
What Does Wi-Fi 7 Offer?
From a user and business perspective, Wi-Fi 7 brings meaningful advantages: faster speeds, lower latency, and better support for high-density environments. These improvements could reduce reliance on fixed cabling, enhance mobile working, and future-proof wireless investments.
From a technical standpoint, Wi-Fi 7 (802.11be) builds on Wi-Fi 6E. It leverages the 6GHz spectrum and offers major advances in performance and efficiency.
Industry-wise, we’re seeing renewed investment in enterprise-grade wireless. Manufacturers are sunsetting older product lines and releasing more advanced models, helping organisations benefit from improved competition and performance.
| Feature | Wi-Fi 6E | Wi-Fi 7 |
|---|---|---|
| Standard | IEEE 802.11ax | IEEE 802.11be |
| Spectrum | 2.4 GHz, 5 GHz, 6 GHz | 2.4 GHz, 5 GHz, 6 GHz |
| Max speed | 9.6 Gbps | Up to 46 Gbps |
| Channel width | Up to 160 MHz | Up to 320 MHz |
| Modulation | 1024 QAM | 4096 QAM |
| Latency | Low | Lower |
Is Now the Right Time to Upgrade?
That depends on your specific situation. Here are the main considerations:
Device Compatibility: Wi-Fi 7 is backward compatible, but to realise its benefits, you’ll need both access points and end-user devices that support it. Many flagship laptops and smartphones already do — and broader adoption is coming quickly.
Cost and Infrastructure: Beyond the access points themselves, organisations may need to upgrade switches, cabling, and power supplies. While this comes at a cost, it should be weighed against the performance gains and the potential to reduce cabling.
Network Readiness: Wi-Fi 7’s performance relies on the right supporting infrastructure. That includes Cat 6 or better cabling, sufficient PoE budgets, available switch ports, and adequate cooling and rack space.
Legacy Wi-Fi Planning: Older standards like Wi-Fi 5 are already being phased out by many vendors. Wi-Fi 6 and 6E will be around for a while, but it’s important to plan your roadmap now.
Why Redesign, Not Just Replace?
Wi-Fi 7 operates at higher frequencies, which means shorter signal range. Simply swapping out access points like-for-like won’t deliver the full benefits. More access points will often be required, and careful planning is essential to avoid poor coverage and unnecessary costs.
For example, in a 3,384m² office:
- 2.4GHz: 6 APs
- 5GHz: 16 APs
- 6GHz (Wi-Fi 7): 19 APs
While that may seem like a large increase, the bandwidth improvements are significant. In one test, throughput increased from 180 Mbps on 2.4GHz to over 700 Mbps using Wi-Fi 7.
In Summary
Wi-Fi 7 is set to become the next enterprise standard — but not overnight. For most organisations, adoption will happen gradually over the next three to five years. However, careful planning now will pay dividends later.
If done right, Wi-Fi 7 can support the modern workplace with the speed, stability, and scalability it demands. If done without a plan, it may lead to costly upgrades with underwhelming results.
At PTS, we help organisations make the transition confidently — from early modelling to final deployment.
