Delay Measurements over 5G Networks

5G networks offer high throughput coupled with ultra-low latency. Because so many applications will rely on 5G speeds, it is important to rigorously test these networks for performance. GL's solution can precisely measure One-Way Delay (OWD) and Round-Trip Delay (RTD) with millisecond accuracy. This solution uses the Dual UTA HD and VQuad™ software to control 5G compatible cell phones via Bluetooth® or through an ACC headset cable. Users can set up phone calls through the VQuad™ software either manually or automatically through scripts. One Dual UTA HD can interface with up to two cell phones independently. Alternatively, if the cell phones are in different geographic locations, two Dual UTA HD's can be used: one for each phone. The OWD measurement is performed using GPS receivers (necessary if the phones are geographically separated) or by using the internal clock of the Dual UTA HD (if both phones are connected to the same Dual UTA HD).

The measurements can be saved and sent to an optional central database. Users may view the results using GL's WebViewer™, a web-based dashboard which accesses the central database. Furthermore, the measurements can be viewed as a function of location using Google Maps. This is useful when testing 5G coverage.
