SWAT (Signal Wireless Assessment Tool) is a comprehensive mobile application developed by Xpertnest for Openreach Ltd., designed to assist field engineers in diagnosing and optimizing in-home Wi-Fi performance. Built using native iOS development technologies, the app combines advanced network diagnostics, real-time throughput measurement, and augmented reality to deliver an end-to-end solution for Wi-Fi optimization.

Key functionalities include:

Wi-Fi Signal Mapping: Engineers can measure signal strength in various areas within a property, visualizing signal loss or interference in real time.

Speed Testing Module: Built-in testing tools measure download, upload, and latency metrics for accurate performance diagnostics.

Floor Plan Designer: Users can create custom floor plans for each level of a home using an intuitive drawing tool, enabling precise localization of problem areas.

Multi-Floor and Home Plan Management: Engineers can save and manage multiple floor plans or entire home layouts, enabling consistency across service visits.

One of the app’s most innovative features is its LiDAR-powered floor scanning capability:

Using Apple’s ARKit and LiDAR sensor, engineers can capture exact room geometry in seconds by tapping on walls and swiping for doors and windows.

This creates precise, scalable 2D floor plans with centimeter-level accuracy, drastically reducing manual effort and time.

The app also integrates recommendation algorithms based on Openreach’s internal best practices to suggest optimal router or repeater placements. Engineers receive actionable insights based on measured data and floor geometry.

Additional highlights:

Offline Mode: Allows engineers to use the app in areas without connectivity and sync results later.

Secure Data Storage & Sync: Integration with secure cloud services enables data backup and seamless access across devices.

User Experience (UX): Optimized for field usability with a clean, minimal interface and guided workflows.

SWAT empowers Openreach engineers to deliver a faster, smarter, and more customer-centric Wi-Fi optimization experience — ultimately reducing repeat visits, improving broadband performance, and enhancing customer satisfaction.
