Thalwil, Switzerland – February 24, 2015 – u‑blox, a global leader in wireless and positioning modules and chips, announces full production availability of the 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 14.8 mm x 14.8 mm footprint and 2.5 mm height. ELLA‑W1 modules feature best‑in‑class radio performance, an operating temperature range of -40 °C to +85 °C, automotive qualification to VW 80000/ISO 16750‑4, and European, US, and Canadian certifications.

Engineering samples and development kits are available now.
