Performing RAN performance testing
The JD780A series provides the optional feature that lets you conduct correlated uplink and downlink
testing with your instrument connected to your mobile device via Bluetooth. The RANAdvisor TrueSite
application installed on your smartphone collects data and transfers uplink data based on your
parameter settings and then your instrument consolidates the data into the measurement results and
displays them as performance indicators. It helps you troubleshoot a problem and identify the cause of
the problem fast.
To perform this testing, you need both of these installed: the license for the option 015 LTE-TDD RAN
Performance Indicator on your instrument and the RANAdvisor TrueSite app with the license on your
smartphone.
Preparing your smartphone for remote control via Bluetooth
To set up a Bluetooth connection and enable data collection with remote control properly, you need to
pair your instrument with your smartphone and set the app's local Bluetooth control option to Slave
once at the beginning.
Procedure

Connect a Bluetooth adapter to the USB Host port and an Omni antenna to the RF In port of your
CellAdvisor instrument.
