Test the very latest Bluetooth standards with the CMW test platform from Rohde & Schwarz


The Bluetooth Special Interest Group (SIG) ratified its core specification version 5.1 in late January 2019. In response to this, Rohde & Schwarz has now launched the world’s first test solution for Bluetooth® 5.1 as a software upgrade for the R&S CMW test platform.

This test solution for Bluetooth® 5.1 can be used to verify the performance of location services which have been significantly improved with the new Bluetooth® specification. 

Improved navigation services.

With the new Bluetooth® core specification version 5.1 (BT 5.1), Bluetooth® Low Energy (BLE) devices can optionally offer improved navigation services. Additional functionality for direction finding (angle estimation) using the angle of arrival (AoA) and angle of departure (AoD) methods enables position determination with accuracy down to centimetre level in both the transmit and receive direction. Previous solutions could only provide metre-level accuracy.

Devices with BLE 5.1 functionality are suitable for tasks such as indoor asset tracking and for navigation services at airports. Beacons are already being used to call attention to specific nearby products, sights and attractions in public spaces. BLE 5.1 now makes it possible to guide interested parties precisely to these points of interest. The Bluetooth® SIG expects that by 2022 around 400 million additional devices will use the Bluetooth® 5.1 location services solutions.

Testing products in line with Bluetooth® 5.1

To enable you to test your products in line with Bluetooth® 5.1, Rohde & Schwarz has expanded its BLE test solution to include 23 new test cases in direct test mode (DTM) defined in the new RF-PHY.TS.5.1.0 test specification. With these tests, you can demonstrate that your products are RF interoperable with other devices and that direction finding meets the requirements of the BT 5.1 specification.

Comprehensive Bluetooth® RF tester

The R&S CMW delivers the full range of Bluetooth® RF tests, including Bluetooth® Classic, Bluetooth® LE and Bluetooth® 5.1. In addition to DTM and signaling tests, it supports a wide scope of audio tests on Bluetooth® basic rate/enhanced data rate (BR/EDR) links. The CMW is particularly suitable for tests in the development phase, pre-conformance tests, qualified audio tests, and for use in Bluetooth® OTA test systems.

Bluetooth®, WLAN and Zigbee tests in one box

The CMW uses a parametric test concept that enables you to create application-specific test sequences. The test platform bandwidth has been extended to 160 MHz, allowing WLAN RF signaling tests in line with the IEEE 802.11a/b/g/n/ac standards, including IEEE 802.11ax. RF tests compliant with IEEE 802.15.4 for Zigbee and Thread components are supported as well.

The new Bluetooth® 5.1 software upgrade is now available from MCS Test.
