u-blox has recently released the RUBY-W2 series (RUBY-W273-05A and RUBY-W295-05A) of automotive Wi-Fi 7 modules designed for advanced infotainment and telematics applications. These modules support tri-band Wi-Fi 7 and dual-mode Bluetooth 5.4, with up to Gbps (PHY) of throughput, supporting simultaneous use cases for in-car hotspots, Apple CarPlay, and multi-client video streaming.
Key features of this module include Multi-Link Operation (MLO) with Dual Band Simultaneous (DBS) and High Band Simultaneous (HBS) modes, 2×2 MU-MIMO, Bluetooth LE Audio, long-range Bluetooth, security with WPA2/3, and secure boot. The modules are based on Qualcomm’s QCA6787AQ or QCA6797AQ automotive chipsets and connect to the host via PCIe for Wi-Fi and UART/PCM for Bluetooth.

In terms of software, the module supports Android and Linux, the driver provided by Qualcomm, but other than that, there is not much information available at the time of writing.
The product summary also mentions evaluation kits (EVK-RUBY-W295-00C and EVK-RUBY-W273-00C) for the RUBY-W2 series automotive Wi-Fi 7 modules but the company has yet to provide any information on those.
Previously we have written about modules like Complex Systems WLTE7002E25 an M.2 Wi-Fi 7 module with Dual-Band Dual-Concurrent Operation, MLO, and Open Source Ath12k Support. We have also written about SoCs like the Qualcomm Wi-Fi 7 Networking Pro Series, but this is the first time we have written about a Wi-Fi 7 module designed for automotive applications.
The company has not provided pricing information about the module, but more information can be found on the product page and the press release.
