Read full descriptionHide full description
Nemo Active Testing Application is the Keysight proprietary communications interface and application developed for iOS based smartphones (patent pending). With the Nemo Active Testing Application (NATA) interface iPhones communicate with PC-based applications, such as Nemo Outdoor and Nemo Invex. NATA provides the real QoE measurements as all the data services are running on a smartphone. A PC user controls and runs the services on the phone via an NMR interface. The NATA application on the phone transfers the KPIs related to the data transfer to the PC. NATA is the solution for current and future technologies supporting high data rates. This initial version of NATA for iOS includes support for the following data protocols: FTP, HTTP and Ping testing. NATA also provides GPS positioning for all the measurement results. Key Benefits - Measurement is done from end-user perspective using smartphone’s QoS settings - No issues with PC CPU load lowering data rates. No need to tweak TCP/IP settings on the PC User can select via the Nemo Outdoor device configuration settings the appropriate method for performing data transfers. The NATA application must be installed on a iPhone. If NATA is activated, all supported commands/services are always executed via NATA. Commands/services that are not supported by NATA are automatically executed on the PC. The user interface uses the same manual and scripted commands with NATA as with PC.
