5G NR tester set for Mobile World Congress debut

Most network operators will implement 5G New Radio (NR) as an extension of their existing LTE mobile network (NSA). As a result, mobile devices will have to function in both worlds simultaneously. So Rohde & Schwarz has developed the R&S CMX500, a radio communication tester for 5G NR that can be seamlessly integrated into an existing LTE test environment.

It is also ideal for tests in 5G NR standalone (SA) mode.

Most mobile network operators will initially use fifth generation mobile communications (5G) as an additional channel to further increase transmission rates. To enable developers to test their mobile devices in line with 3GPP specifications in 5G NR non-standalone mode, their test solution must seamlessly integrate into existing LTE test setups.

This will make it possible to comprehensively test the signaling, RF parameters and data throughput rates of simultaneous LTE/5G connections in dual connectivity mode.

Rohde & Schwarz will present the CMX500 radio communication tester for the first time at Mobile World Congress 2019 in Barcelona (February 25-28). The instrument adds 5G NR signalling and RF testing to existing R&S CMW 500-based LTE T&M solutions in labs.

Users who already have an R&S CMW500 or R&S CMWflexx test system for LTE measurements can continue to use them and only need an R&S CMX500 as an extension box to perform tests on 5G NR signals.

This setup allows use cases to be tested in non-standalone (NSA) mode as specified in 5G NR option 3.
