Most repeat truck rolls for cable operators installing Wi-Fi 7 gateways in residential homes aren't caused by network failures; they are caused by issues a proper first-visit workflow could have caught. VeEX’s WX90 gives technicians that workflow in three steps, reducing truck-roll costs and creating new revenue opportunities. By scanning all three bands (2.4/5/6 GHz), the WX90 reveals the full RF environment: every AP in range, signal strength, noise, SNR, co-channel and overlapping channel conditions, and where each access point sits across the frequency span. It also generates a real-time heatmap directly on the device without connecting to the network. A compelling element of the WX90 is that its passive features, including RF scan, heatmap, spectrum analysis, and interference detection, all run without a password, allowing technicians to identify and explain most coverage and interference problems. When a password is available, a connected mode unlocks real speed testing, room-by-room QoE validation, and wired WAN verification.
