The industry’s first Wi-Fi 6 solution built for next-generation
connected vehicles

The 88Q9098 Family

The 88Q9098 family of automotive wireless SoCs is the industry’s first Wi-Fi 6 solution, based on the latest IEEE 802.11ax standards, with 2x2 plus 2x2 concurrent dual Wi-Fi, dual-mode Bluetooth 5/BLE and 802.11p for connected vehicles. Delivering reliable and high-performance wireless connectivity is becoming more difficult in the increasingly congested automobile environment. The new 88Q9098 combo solution enables gigabit-level performance, superior reliability, and enhanced security for the car and extends Marvell leadership in providing comprehensive Wi-Fi 6 solutions. Our innovative concurrent dual Wi-Fi architecture sets a new technology precedent, integrating two complete Wi-Fi subsystems into a single SoC, and enabling two independent 2x2 data streams to run concurrently and at full throughput.
