At Mobile World Congress (Barcelona, Spain, Feb 24 to 27) Rohde & Schwarz and Elektrobit will team up to present what is claimed to be the world’s first live demonstration of high-power user equipment (HPUE) testing.

With the recent firmware release, the R&S CMW500 wideband radio communication tester from Rohde & Schwarz now supports HPUE tests. The Elektrobit HPUE demonstrator is the first device able to transmit at the high output power of +31 dBm as intended for operation in Band 14. In this demonstration the R&S CMW500 emulates an LTE Band 14 network, in which the Elektrobit DUT registers. The R&S CWMrun sequencer software controls the entire setup to run all required transmitter and receiver tests, including the newly added higher output power test cases, to verify user equipment (UE) transmitter performance.

Jani Lyrintzis, Vice President, Business Development and Sales, Elektrobit said, “High-power user equipment capability will be important especially during the early phases of FirstNet network rollouts when coverage is limited. Adding this capability quickly on top of EB’s specialized device platform nicely demonstrates the platform’s modularity and scalability, while increasing its attractiveness and use case and customer potential.”  

With LTE becoming the global wireless communications standard for delivering mobile broadband data and high-definition voice, and soon also offering public safety features, governmental authorities in the United States have decided to adopt the LTE standard for critical communications. There, FirstNet is currently in charge of deploying, maintaining and servicing a dedicated LTE-based network for reliable communications for first and second responders. LTE Band 14 was made available for this undertaking. The public safety network will be based on a 2x10 MHz spectrum allocation.

With their joint demonstration, Rohde & Schwarz and Elektrobit are paving the way to get LTE ready for public safety applications. The test setup at Mobile World Congress is located at the main Rohde & Schwarz booth, Stand C40 in Hall 6.
