Bluetooth, WiFi for in-car use combined in one module

January 27, 2015 // By Christoph Hammerschmidt
Addressing the rising demand for systems that integrate smartphones into the infotainment system in vehicles, Alps has developed a module that combines Bluetooth and WiFi functionality in one product, the UGZZF series.

Increasing smartphone functionality has given rise to new services making use of cloud-based data, a trend creating spillover effects for the automotive electronics market. Car navigation, display audio and other automotive systems incorporate Bluetooth communication functionality for such features as hands-free calls and music playback using a smartphone or similar device. In recent years, however, wireless LAN is increasingly being added to enable high-speed communication with cloud networks via LTE-capable smartphones.

Additionally, systems which use Bluetooth, as modules that also contain an antenna, must have Bluetooth SIG certification, as well as any certification specified by radio legislation in each country. This necessitates spending an enormous amount of time and effort on examination and testing. Furthermore, many car audio and other automotive systems have CPUs with low processing capability, feeding demand for modules with integrated Bluetooth protocol stack and wireless LAN driver.

The antenna-integrated UGZZF Series Bluetooth/Wireless LAN module is ALPS' answer to this set of needs. By incorporating the Bluetooth protocol stack into the module, ALPS takes responsibility for obtaining for the module both Bluetooth certification and certification required by regional radio legislation. The module is also equipped with a wireless LAN driver, enabling Wi-Fi connections without burdening the host CPU. The module meets the requirements of a wide range of customers and also helps to reduce the antenna and system design and testing, software development and certification workload of equipment manufacturers.
