Read full descriptionHide full description
WalkTest is a brand-new app built from the ground up to test indoor cellular/wifi performance. The simple user interface allows users to record various speed metrics throughout a building and produce detailed reports on the performance of the cellular/wifi network. You can use the data from the WalkTest app to help you understand where you have cellular/wifi issues in your building, provide reports you can share with your provider, and provide the information you need to design a system to improve coverage. - Test Multiple Providers at Once: WalkTest allows you to connect multiple devices to the main device, allowing you to record data from multiple providers while only needing to mark points on one device. - Wide Variety of KPIs: WalkTest allows you to measure and map multiple KPIs including download speed, upload speed and latency. - Simple, Easy-to-Use Collection UI: Once you have uploaded your PDF floorplan on the main device, you can simply mark your location on the plan as you walk around the building. The app will then analyze the route you have taken and intelligently distribute collected data points along the route. You can even pin the floorplan to the correct location in Google Maps, ensuring that all exported data will have the correct latitude and longitude. - Produce Beautiful, Detailed Reports: The report feature allows you to export PDFs of metric averages and coverage maps for all KPIs and all floors. - Custom Thresholds: Exported reports include coverage maps and average metrics across various threshold bands. The settings section of the app allows you to define these bands and have that data reflected in the exported reports. - CSV Export: The CSV export functionality will export geocoded data of all KPIs to use it with external tools. - In-App Support: Should you need any help with the app, please reach out via the Live Chat within the app, or you can drop us an email.
