RF Field data and playback

Field RF and Data Playback

Companies as Spirent Communications use tools to collect RF data and play it back for testing again. Companies are looking for ways to capture “Drive Test” RF data as RSSI and use fading models to replay certain Physical level conditions that trigger what modulation mode the phone will be used. At the same time, the RF will trigger switching on bandwidth and bit rates, power transmission, and battery usage.

One interesting tools is called Live2Lab, a tool that handles capture of data and playback in the SR5500 Wireless Channel Emulator, and other tools that combined can provide a full test for switched calls, VoLTE calls, applications, and data.

Companies like ROHDE & SCHWARZ, AeroFlex, and others provide similar environments for testing.

In summary, RF data is captured from the field (via “Drive Test Tool”) and then converted or imported to a format that can be played back to the handset or handsets, once the data from 1-10 sectors is known, the base station signaling can be emulated in a form that the handsets perceives the drive test.
