Marvell's 802.11ax Concurrent Dual Wi-Fi Targets Next-Generation Connected Cars
June 12, 2018
The 88Q9098 wireless SoC offers 802.11ax two-by-two plus two-by-two concurrent dual Wi-Fi operation.
Marvell recently introduced what it claims is the industry’s first high-efficiency wireless 802.11ax solution with “two-by-two plus two-by-two” concurrent dual Wi-Fi, dual-mode Bluetooth 5/Bluetooth Low Energy, and 802.11p for connected vehicles. The 88Q9098 combo solution enables gigabit-level performance, high reliability, and enhanced security for the car. The innovative concurrent dual Wi-Fi architecture integrates two complete Wi-Fi subsystems into one SoC, and enables two independent two-by-two data streams to run concurrently and at full throughput.
One use case that requires this capability is when one Wi-Fi radio is dedicated to mobile phone projection while the other is streaming video to and from mobile/accessory devices in the car. The 88Q9098 enables reuse of a single solution across infotainment and telematics applications, delivering market-leading multimedia streaming, secure over-the-air updates, vehicle-to-vehicle (V2V) communication and hot-spot functionality.
Purpose-built for the car, this SoC offers customizable firmware so OEMs can enhance and differentiate their solutions. The 88Q9098 also meets the quality, reliability and temperature standards required for automotive AEC-Q100 grade 2 operation from -40°C up to +105°C.
