Rohde & Schwarz Will Present Radiocommunications Test Solutions For 5G NR And LTE-A Pro 8CA

At Mobile World Congress 2018, Rohde & Schwarz will showcase its innovative solutions in keeping with its theme "Optimizing the present. Designing the future." For chip manufacturers, the first one-box 5G NR test solutions will be on display. Rohde & Schwarzwill also present the world’s first test solution for a chipset that utilizes enhanced Carrier Aggregation (eCA) for LTE mobile broadband transmissions. The chipset receives and processes eight downlink carrier signals in parallel, allowing transmission rates of up to 2 Gbit/s in current LTE networks.

Fifth generation (5G) mobile communications offers communications solutions for diverse key areas of applications. Data rates of 10 Gbit/s and more are possible with 5G New Radio (NR). These are achieved through higher bandwidths of up to 100 MHz in the traditional mobile radio bands (sub-6 GHz range) and up to 800 MHz in the millimeterwave (mmW) range. Signals in the mmW range experience strong attenuation in the atmosphere. Antenna arrays with narrow pencil beams are used to minimize losses due to attenuation. As a result, conventional conducted tests are increasingly being replaced by over-the-air (OTA) tests.

At MWC 2018, Rohde & Schwarz is already addressing the mobile communications needs of the future by presenting 5G NR sub 6 GHz and 5G NR mmW test solutions. Since many network operators will continue using their LTE networks, Rohde & Schwarz is at the same time driving 4G technology and will exhibit new 4G test solutions. This allows network operators to utilize added value generated from their existing infrastructures for the introduction of 5G.

R&S CMP200 one-box tester and OTA test system for 5G NR mmW range

Rohde & Schwarz will demonstrate its new R&S CMP200 radio communication tester for the 28 GHz and 39 GHz frequency bands. The tester is designed for 5G NR OTA measurements and consists of an IF unit and remote radio heads (RRHs). Users can position the RRHs as close as possible to the OTA antenna test chamber to minimize cable losses during the measurements. Rohde & Schwarz will showcase the R&S CMP200 as a complete OTA test solution together with the R&S ATS1000 antenna test system and accessories such as Vivaldi antennas from Rohde & Schwarz and the R&S NRPM OTA power measurement solution.

R&S CMW100 one-box tester for 5G NR sub 6 GHz range

The latest version of the leading R&S CMW100 production tester supports 5G NR TX and RX measurements. The solution is fully compatible with the 2G, 3G and 4G cellular technologies and with wireless technologies such as WLAN and Bluetooth®. The new 5G test options can be enabled via license keys.

R&S CMWflexx test solution for LTE-A Pro 8CA

Another highlight on display will be a Rohde & Schwarz test solution for verifying chipsets that support the 3GPP Rel. 13 enhanced Carrier Aggregation (eCA) feature. The solution makes it possible to test user equipment that is capable of receiving up to 8 downlink carriers in parallel. It is based on an R&S CMWflexx test set consisting of two R&S CMW500wideband radio communication testers.

At MWC 2018, from February 26 to March 1, 2018, Rohde & Schwarz will showcase these innovative solutions in hall 6, booth 6C40. For more information, visit www.rohde-schwarz.com/mwc.
