U-Blox automotive module handles wifi and Bluetooth

U-Blox Jody-W1 automotive-grade module

U-Blox has launched Jody-W1, a host-based automotive-grade module that enables real simultaneous dual band (RSDB) operation for faster, concurrent wifi connectivity on the 2.4 and 5GHz bands. 

As it supports both dual-band wifi with 2x2 mimo 802.11ac and dual-mode Bluetooth (Bluetooth and Bluetooth Low Energy) 4.2, it is suitable for in-vehicle-infotainment and telematics applications requiring high data rates and concurrent connectivity, such as in-car hotspots, wifi screens (Apple CarPlay, for example) 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 wifi screen could independently operate on the 5GHz band and the wifi hotspot on the 2.4GHz band, improving overall robustness and per-band data rates compared with chipsets using time-division multiplexing for dual-band support.

“Thanks to RSDB support, Jody-W1 offers best-in-class performance when operating as an access point, station, or in P2P mode on different bands in parallel,” said Kilian Frank, product strategist at U-Blox. “Combined with excellent Bluetooth and wifi co-existence, it is the ideal choice for applications with concurrent use cases.”

The module measures 19.8 by 13.8mm. It comes optionally with an integrated LTE filter for applications requiring LTE and wifi antenna co-location.

It complies with the automotive quality requirements, contains an AEC-Q100 compliant chip – BCM89359 – and is manufactured to ISO/TS16949, with automotive service level including PPAP, 8D report and full component traceability. 

Tested engineering samples will be available in the second quarter of 2017.
