Bluetooth® testing

Rohde & Schwarz offers the most comprehensive test solutions for Bluetooth® testing, applicable from design and certification to production

Bluetooth®, initially developed 20 years ago, is a frequency hopping spread spectrum technology that operates in the globally available ISM band at 2.4 GHz. Initial requirements aim at a data connection based on certain protocol stack profiles (such as audio, file exchange or video) of around 700 kbit/s in an ad hoc network configuration. With the Bluetooth® 2.0 specification, an enhanced data rate (EDR) of up to 3 Mbit/s was specified. Following the trend towards lower power consumption, the Bluetooth® SIG started to specify the Bluetooth® low energy (LE) technology, typically used in all kinds of wearables, peripherals or IoT devices requiring ultra-low data communication. With Bluetooth® 5, the Bluetooth® SIG paved the way for the internet of things with features for long-reach, higher data rates, and advanced advertising capabilities. The Bluetooth® specification 5.1 further extended these capabilities in order to enable, for example, precise indoor positioning. Version 5.2 added audio support for Bluetooth® LE and power control mechanism.

Rohde & Schwarz test solutions for Bluetooth®

Test and measurement solutions from Rohde & Schwarz support Bluetooth® basic rate, EDR and LE in line with Bluetooth® core specifications v1.2, 2.0, 2.1, 3.0+HS, 4.0, 4.1, 4.2, 5, 5.1 and 5.2. The Bluetooth® SIG has qualified the R&S®CMW wireless communication tester for RF testing. Supporting Bluetooth®, WLAN and other non-cellular and cellular technologies in the same equipment makes the Rohde & Schwarz solutions ideal for verifying IoT devices. With our unique Bluetooth® test solutions in signaling mode, Rohde & Schwarz stays at the forefront of innovation, allowing easy-to-use testing of Bluetooth® devices over the air.

Bluetooth® test solutions

Bluetooth® Classic for wireless voice and audio

Bluetooth® Classic is primarily used for wireless audio devices, such as headphones or portable speakers. This means that in addition to transmitter and receiver tests, it is also necessary to perform audio quality tests.

Bluetooth® Low Energy (LE) for wearables, peripherals and IoT

Bluetooth® LE is an ultra-low-power version of Bluetooth® meant for low-power devices such as peripherals, wearables or sensors used in a wide range of applications from medical to automotive. It is ideal for applications that do not require continuous connection but depend on long battery life.

On-demand webinar

Everything you need to know about Bluetooth® Low Energy (LE) in 2020

Bluetooth®LE is among the most successful wireless technologies for the internet of things (IoT). Over the last decade, the use cases have evolved from connecting PC peripherals to full communications with wearable devices, and even more. The latest releases (5.0, 5.1, 5.2) of the Bluetooth® specification open the door to even more applications in the IoT area, such as smart homes, smart buildings and indoor location services.

The webinar will introduce the latest features you should know about, such as long range or direction finding, and explain related test challenges and solutions. It will also highlight a novel solution of a radio-controlled test mode, which will redefine the way of testing upcoming Bluetooth® LE devices.
