Pilot Pioneer NB-IoT Scanner Measurements with R&S TSME

Dingli Corp Ltd cooperates with Rohde & Schwarz (referred as R&S for remaining of this article) to include the support of R&S's TSME scanner functionality as part of Dingli's NB-IoT radio access network test and measurement solution.  

This integration is part of Pilot Pioneer 10.2 offering, which also introduces the support of various NB-IoT sensors or test modules base measurements (apart from multiple commercial test devices), for indoor or outdoor field test. This strengthens DingLi's Pilot Pioneer product positioning with multi-technology radio access network measurement support, powerful and accurate data collection and analysis capability.  

Both NB-loT radio access network and test modules would have its challenges during network tuning and measurements. These can be summarized as:

● NB-IoT radio access network: Overlapping Coverage, Overshooting Coverage, Poor Coverage, Co-channel Interference, IRAT interference, Illegal Signal Interference.

● NB-IoT test modules: Cell reselection is available only during idle mode, which affects the modules' accuracy and continuous coverage measurement capability.

Therefore, Dingli's Pilot Pioneer solution includes not only test modules or sensors measurements, but compliment it withR&S TSME scanner to provide independent RF scan measurement not affected by network or devices limitations. As for thescan test, once connected, Pilot Pioneer shall obtain scanner measurements directlv from the air interface, which avails thesoftware of additional network problem diagnosis capability,. DingLi's Pilot Pioneer NB-loT with R&S TSME scan solutionprovides accurate RF scan measurement for network tuning and coverage verification with the following advantages:

● Scanner performance: High accuracy and high sensitivity, stable performance, high speed scan;  

● Technology: Verified and recognized by China Mobile Research Institute;  

● Statistics function: Powerful statistics function satisfies the drive test technology standards specified by various operators  

● Analysis function: Automatic analysis, one-click smart analysis
