Bluetooth/WLAN automotive networking all in one module, from ALPS

January 27, 2015 // By Graham Prophet
ALPS has developed the “UGZZF Series” Bluetooth/Wireless LAN All In One Module for Automotive Use, for wireless connection between automotive equipment, such as car navigation systems, and mobile devices.

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. Wireless LAN is increasingly being added to enable high-speed communication with cloud networks via LTE-capable smartphones.

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 expending time and effort on examination and testing. 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.

ALPS’ antenna-integrated UGZZF Series is a Bluetooth/Wireless LAN All In One Module for automotive use. 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. Supporting both Bluetooth and wireless LAN communication with a single package, 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. The antenna is integrated into the module.
