Bluetest and Rohde & Schwarz to provide fast and stable LTE CA OTA measurement solution

Göteborg, December 3rd, 2015 – Bluetest and Rohde & Schwarz have expanded their combined Over-the-Air (OTA) test solution to include 4CC downlink measurements. The solution consists of the R&S CMWflexx solution from Rohde & Schwarz in combination with Bluetest’s reverberation chambers RTS65/RTS95 and measurement software Bluetest Flow.

During the last two years the wireless industry has quickly expanded the LTE communication capability with LTE-Advanced by introducing LTE carrier aggregation: 2 downlink CC (component carriers) was introduced in 2013, 3 downlink CC in 2014 and 2 uplink CC this year. Bluetest and Rohde & Schwarz have continuously supported LTE-Advanced with their OTA test solution providing measurement capability matching the needs of the industry.

With Bluetest’s RTS it is quite easy to add carriers to the test set-up. Bluetest RTS is available with up to 8 measurement ports, hence supporting a R&S CMWflexx solution with 4 MIMO enabled carriers without any external combiners.

The R&S CMWflexx has been especially designed for testing LTE-A with a high number of component carriers. It is the latest addition to the R&S CMW500, the universal tester for testing the air interface of wireless devices. The instrument can be used in all phases of product development and production and supports all common cellular and non-cellular wireless technologies. Additional information is available at
