The RivieraWaves Wi-Fi IP family is a comprehensive suite of IPs and platforms for embedding Wi-Fi 802.11a/b/g/n/ac/ax into SoC/ASSP. Together with the Bluetooth IP family – both low energy (BLE) and dual mode (BTDM) versions – the Wi-Fi IP family forms part of CEVA’s popular and production-proven RivieraWaves Wireless Connectivity portfolio.
Each RivieraWaves Wi-Fi solution incorporates PHY modem functions and MAC functions, including Lower MAC (LMAC) and Full MAC software protocol stacks. The IP is provided with an integration-ready processor and operating-system- agnostic platform, simplifying deployment in SoC/ASSP designs. An optimized Wi-Fi & Bluetooth coexistence interface with a Packet Traffic Arbiter is also available for smooth simultaneous operation.
The modem can be either a hardwired function (for minimal die area and extremely low power consumption) or a software-defined modem (SDM) that gives extra flexibility for multi-protocol connected devices. RF partners including Catena, Sabertek, and others help address deployment on various foundries and processes.
The RivieraWaves Wi-Fi IP family addresses a broad range of applications and contains a suite of solutions, each optimized for various target products, with a range of configurations. The Wi-Fi family is organized into 3 categories:
- Wi-Fi Low Power: optimized for small, low cost and low power IoT devices, wearables, medical, low end smartphones and wireless audio, it includes 802.11n 1×1 and 802.11ax 1×1 20MHz configurations.
- Wi-Fi High Performance: addressing a vast array of media-sharing consumer devices, including smartphones, tablets, cameras, and smart-home products, it supports configurations such as 802.11n 2×2, 802.11ac 1×1 & 2×2, 802.11ax 1×1 & 2×2.
- Wi-Fi Multi-Gig: tailored for advanced products dealing with high data traffic including access points, media gateways, and Wi-Fi offload in small cells, it provides 4×4 configurations of 802.11ac and 802.11ax.
The RivieraWaves Wi-Fi IP family offers designers a choice of small footprint, ultra-low power consumption, high bandwidth, and high performance solutions. Optimized implementations are available that target a broad range of connected devices, including smartphones, wearables, smart-home, consumer & industrial IoT, and automotive applications.
- Full support for 802.11a/b/g/n/ac/ax
- Optimized solutions to match target application in terms of power, area, performance and flexibility, spanning 1x1, 2x2, 4x4 configurations
- Supports both 2.4 and 5.0GHz bands
- Bandwidths up to 80MHz
