Is Wi-Fi 7 worth it? Migration tips to avoid costly downtime

Before upgrading to Wi-Fi 7, organizations must ask: is Wi-Fi 7 worth it without upgrading their wired infrastructure first?

Wi-Fi 7 will become the dominant wireless standard in the next few years, with Wi-Fi 7 access point (AP) shipments set to represent one-third of indoor AP revenues in 2025 and 90 percent by 2028.

The reasons for such widespread adoption, by businesses especially, are obvious: Wi-Fi 7 delivers higher speeds – theoretically up to a sizzling 46 Gbps, four times faster than Wi-Fi 6 – lower latency and greater network efficiency than any other standard.

But some projects run into serious issues when upgrading to Wi-Fi 7 because they haven’t considered their wired network requirements in advance – leading to delays, cost overruns and other issues.

Technical issues that can impede an upgrade to Wi-Fi 7

A robust wired infrastructure is crucial for Wi-Fi 7 to function optimally. Technical issues can include:

• Power supply issues: Wi-Fi 7 access points have specific power requirements. Performance issues and outages can result from underestimating those requirements or not using power over Ethernet (PoE).
• Hardware that can’t keep up: Without upgrading your switches and routers, they won’t be able to handle Wi-Fi 7’s increased traffic and speeds.
• Old cabling: Wi-Fi 7 requires Cat 6, Cat 6a or Cat 7 quality cabling to achieve high speeds.
• Not upgrading your network: Your wired network will become a bottleneck without upgrading to multi-gigabit Ethernet ports.

Without upgrading your wired backbone, your business will likely run into serious performance issues or even network outages.

Best practices for a successful upgrade to Wi-Fi 7

Wi-Fi 7 isn’t just about changing APs – it’s about making sure your switch port speed, power supply and other infrastructure elements are adequate so your APs can hit maximum capacity.

Here are two important physical requirements your wired network should meet before upgrading to Wi-Fi 7:

1. Critical: To work at max capacity, Wi-Fi 7 APs require ~41Watts of power. That means you must ensure APs are connected to switches that support IEEE 802.3bt – without that, your APs will work in limited mode, severely reducing their radio capacities in terms of cell size and maximum number of concurrent connections. This requirement is critical, and if not followed could severely impact the end user experience.
2. Highly recommended: While not critical, it is highly recommended to connect a Wi-Fi 7 AP on a 2.5, 5 or 10Gbps Ethernet port. This requirement must be strongly considered in scenarios where concurrent connections per AP are expected to be high.

Without following these best practices and implementing them in advance, organizations risk technical issues, performance slowdowns and even network outages — raising the question: is Wi-Fi 7 worth it?
