Wi-Fi 7 is the marketing name for IEEE 802.11be, the latest generation of the Wi-Fi standard. It builds on Wi-Fi 6 with substantially higher peak data rates (up to 46 Gbps in theory, with practical rates in current hardware reaching multi-gigabit speeds), wider channels (up to 320 MHz), higher-order modulation (4096-QAM), and Multi-Link Operation (MLO), which lets a device use multiple bands simultaneously for a single connection.

In short: Wi-Fi 7 operates across 2.4 GHz, 5 GHz, and 6 GHz bands, with the 6 GHz band offering substantial new spectrum (in regions that have allocated it for Wi-Fi use, including the UK). Multi-Link Operation is the headline new feature: a Wi-Fi 7 device can maintain simultaneous connections on multiple bands, aggregating their capacity and providing seamless failover between them. This makes Wi-Fi 7 particularly well-suited to latency-sensitive applications like AR/VR, low-latency industrial control over wireless, and dense environments where any single channel might be congested.

For IoT and industrial deployments, Wi-Fi 7 is most relevant where current Wi-Fi 6 deployments are reaching their capacity ceiling, where new applications demand higher throughput or lower latency than Wi-Fi 6 can provide, or where the deployment is being futureproofed for the device generation that will arrive over its operational lifetime. For most everyday IoT (sensors, cameras, simple control), Wi-Fi 6 remains entirely adequate.

Equipment supporting Wi-Fi 7 is now shipping from major vendors. Adoption in industrial cellular routers is following the consumer and enterprise markets, with some models from Teltonika and others offering Wi-Fi 7 on flagship products. For new builds at sites where high-bandwidth applications are part of the use case (rail, broadcast, logistics, manufacturing with high data volumes), specifying Wi-Fi 7 is increasingly justified.
