Wi-Fi and Bluetooth combined in compact host-based automotive module

U-blox has announced full production availability of the new ELLA-W1 series of compact, automotive-grade, multiradio modules. The modules promise predictable, reliable results and easy implementation of in-car wireless connectivity. Applications include hands-free telephony, in-car hotspots, rear view cameras and graphical user interface (GUI) mirroring.

ELLA-W1 is a series of ultra-compact, host-based, short-range transceiver modules offering both simultaneous and independent communications over Wi-Fi 802.11a/b/g/n, Bluetooth V3.0 + HS and Bluetooth V2.1 + EDR. Each module has an integrated MAC, baseband processor and RF front end, and connects to its host via an SDIO 2.0 interface. The dual-band Wi-Fi versions (2.4 GHz and 5 GHz) minimize interference problems from the crowded 2.4 GHz band. The modules operate simultaneously in client (STA) and access point (AP) mode, the latter enabling up to 8 Wi-Fi clients to be connected concurrently.

The ELLA-W1 is a surface-mount module with a 14.8mm x 14.8mm footprint and 2.5mm height. ELLA-W1 modules feature best-in-class radio performance, an operating temperature range of -40C to +85C, automotive qualification to VW 80000/ISO 16750-4, and European, US, and Canadian certifications, says the company.
