Wireless module supports 2 x WiFi and Bluetooth for in-vehicle use

January 31, 2017 // By Christoph Hammerschmidt
In-vehicle WiFi hotspots frequently need to support multiple WiFi connections at the same time. JODY-W1, a new wireless communications module from u-blox, meets this requirement. What’s more, the module also supports dual-mode Bluetooth (Bluetooth/Bluetooth low energy) 4.2.

The module enables real simultaneous dual band (RSDB) operation for faster, concurrent Wi-Fi connectivity on the 2.4 and 5 GHz wireless bands. The concurrent support of Bluetooth makes the device ideal for in-vehicle-infotainment and telematics applications requiring high data rates and multiple concurrent communication processes, such as in-car hotspots, Wi-Fi screens or video streaming across multiple clients.

 

RSDB enables a separation of time-critical services requiring higher data rates from less critical services. In an infotainment application, the Wi-Fi Screen could independently operate on the 5 GHz band, and the Wi-Fi hotspot on the 2.4 GHz band, improving overall robustness and per-band data rates in comparison to chipsets using time-division multiplexing for dual-band support.

The module measures just 19.8 x 13.8 mm, making it one of the smallest modules on the market. It comes optionally with an integrated LTE filter for applications requiring LTE and Wi-Fi antenna co-location. The module complies with the highest automotive quality requirements. It contains an AEC-Q100 compliant chip BCM89359 and it is manufactured according to ISO/TS16949, with automotive service level including PPAP, 8D report and full component traceability among others.

Fully tested engineering samples will be available in Q2 2017.
