Wi-Fi works great in a clean lab. The problem is, no real deployment looks like a clean lab. Real environments have walls, floors, competing access points on adjacent channels, dozens of client devices with different chipsets and driver versions, and interference from Bluetooth, microwaves, and neighbouring networks. A deployment that passes every lab test can fall apart in the field. Slow roaming, throughput drops, clients stuck on the wrong AP, band steering that doesn't steer.
We validate Wi-Fi deployments under realistic RF conditions. Throughput testing across 2.4 GHz and 5 GHz bands. Roaming latency measurements as clients move between access points, covering 802.11r, 802.11k, OKC, and proprietary fast-roaming mechanisms. Interference resilience testing with controlled noise sources. We use a representative mix of client devices, phones, laptops, IoT devices, because testing with a single high-end client doesn't tell you what your actual users will experience.
We also test mesh and controller-based architectures for backhaul performance, AP failover behaviour, and load balancing under high client density. If your customers are going to hit a Wi-Fi problem, we want to find it before deployment. Not after.
