Rohde & Schwarz and Signalion score an industry first with full HD video streaming over LTE - including RF tests in the uplink

(PresseBox) (Munich/Dresden, ) At the Mobile World Congress in Barcelona, Rohde & Schwarz and Signalion raised the bar for LTE test and measurement by demonstrating full HD video streaming over LTE. Using the SORBAS test user equipment (UE) and the R&S CMW500 wireless tester, the two T&M specialists achieved an extremely high data rate of 25 Mbit/s.

For the first time, the streaming server of the R&S CMW500 used 64QAM modulation to transmit the data packets to the SORBAS test UE, which sent the received HD video to a PC with a display. In another LTE test innovation, in parallel with downstreaming data, the SORBAS test UE sent data to the R&S CMW500 via an LTE uplink to allow RF measurements.

The R&S CMW500 wideband radio communication tester from Rohde & Schwarz is an all-in-one solution that covers all phases of development and production. Its LTE implementation features layers 1 to 3 in the protocol stack, all of which meet the specifications of 3GPP eUTRAN release 8 up to category 4. In addition, the general-purpose tester offers scalable channel bandwidths from 1.4 MHz to 20 MHz. All 3GPP frequency bands up to 6 GHz are supported.

Signalion's SORBAS LTE test UE is an all-in-one solution for testing the air interface of LTE base stations in all phases of development. It features layers 1 to 3 compliant with 3GPP specifications. In addition, it provides all the important characteristics of an LTE wireless device in combination with wide-ranging test, tracing and logging functions. This makes it a comprehensive solution that fulfills all requirements for function, load and capacity tests on LTE base stations.
