Signalling test solution for Bluetooth LE unveiled at MWC


One of the major transmission technologies for the IoT is Bluetooth Low Energy (LE). Bluetooth LE components are found in a variety of applications in the automotive industry, in sports and healthcare, in consumer electronics and smart homes, and in other areas. Many of these radio sensors are very small and integrated into equipment.

When drafting the Bluetooth LE test specifications in 2010, Bluetooth SIG specified a direct test mode via a control line but did not specify an OTA signalling test mode. Many small Bluetooth LE devices offer no port or interface to connect a control line. Rohde & Schwarz now presents the first solution for Bluetooth LE signalling tests, facilitating device and component tests for manufacturers.

Fast OTA signalling tests for Bluetooth LE
The Rohde & Schwarz signalling test solution uses OTA measurements on an R&S CMW270 wireless connectivity tester to verify the RF properties and performance of Bluetooth LE devices in operating mode. The DUT's signal level, modulation and receiver sensitivity, among other parameters, can be determined in this way.

The Bluetooth LE signalling functionality of the R&S CMW270 provides the basis for the complex measurements and the wide variety of Bluetooth applications that have emerged as a result of the tremendous growth in the IoT sector. That makes the R&S CMW platform a safe investment also for coming generations of Bluetooth specifications.

Comprehensive Bluetooth RF tester
The R&S CMW270 delivers the full range of Bluetooth RF tests, including Bluetooth Classic, Bluetooth LE, and the latest standard, Bluetooth 5. Users can perform signalling tests and tests in direct test mode, as well as numerous audio tests on Bluetooth basic rate/enhanced data rate (BR/EDR) links. The R&S CMW270 is especially suitable for tests during development and for preconformance tests in preparation for Bluetooth SIG qualification.

Complex Bluetooth, WLAN and ZigBee tests in a single box
The R&S CMW270 wireless connectivity tester relies on a parametric test concept that allows the creation of application-specific test sequences. The tester‘s bandwidth has been extended to 160MHz. That also enables WLAN RF tests covering the IEEE 802.11a/b/g/n/ac and 802.11ax standards. RF tests for ZigBee components, which are often used in smart home environments, are also available.

Rohde & Schwarz will showcase the R&S CMW270 with its full range of functions at Mobile World Congress 2018 in hall 6, booth 6C40. The signalling test function for Bluetooth LE will premiere at MWC, and will be available from Rohde & Schwarz in the first half of 2018.
