Bluetooth “Angle of Arrival” was included in the Bluetooth 5.1 Core Specification, which was released in January 2019. As with all Bluetooth updates, there were several changes within the specification, but Angle of Arrival (AoA) was the only one that gained any real attention.
Over the last decade, processors used in embedded systems have become increasingly sophisticated. Not long ago, simple 8 or 16-bit microprocessors were common. Now ARM core 32-bit processors are almost standard.

Es gibt zwei grundsätzliche Herangehensweisen für die Entwicklung eines drahtlosen Systems - das System von Grund auf aufbauen, mit einem HF-Chip, passiven Komponenten, Filtern und dem Anschluss einer Antenne, oder ein drahtloses Modul verwenden, das all diese Elemente in ein komplettes System integriert.
Designers often want to test the performance of RF products such as Bluetooth modules as part of the product selection process. However, they may find the final performance of their products in the field bears little relationship to their lab tests. This article discussing some of the issues around testing RF products and in particular the way the antenna and system interact to make an impact on any measurements.
Nick Wood, VP Sales & Marketing, Insight SiP explains how design engineers can use SIP (System-in-Package) to squeeze ever more RF functionality into ever smaller spaces for high performance IoT wireless communications.

There has been an explosion in the use of Short Range Wireless Solutions in recent years, driven principally by the arrival and development of the Bluetooth Low Energy (BLE) standard. Whilst plenty of short range wireless solutions existed previously, their uptake was limited. This was either because they focussed on narrow niches such as Zigbee or ANT or were ill-suited to battery powered or intermittent use such as Bluetooth “classic”. BLE fulfilled the original general “cable replacement” objectives of the original Bluetooth standard. With BLE quickly becoming natively available on phones, laptops and tablets, there was a ready-made market of devices to connect to.
There are two basic approaches to designing a wireless system – build the system from the ground up, with an RF chip, passives, filters, and connect an antenna, or use a wireless module that integrates all of these elements into a complete system.
