The RivieraWaves Wi-Fi IP family is a comprehensive suite of SoC/ASSP-embeddable platforms for Wi-Fi 802.11a/b/g/n/ac. Together with the Bluetooth IP family – both low-energy (BLE) and dual-mode (BTDM) versions ­– the Wi-Fi IP forms part of CEVA’s popular and production-proven RivieraWaves Wireless Connectivity portfolio.

Each RivieraWaves Wi-Fi platform incorporates PHY modem functions and MAC functions, including Lower MAC (LMAC) and Full MAC software stacks that are processor- and operating-system-agnostic to make deployment easier.

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 CatenaSabertek, and others help address deployment on various foundries and processes.

The RivieraWaves Wi-Fi family consists of the following platforms:

RivieraWaves Sense: Targeting IoT applications (including wearables, medical, and wireless audio), the 802.11n Sense platform offers the industry’s smallest footprint and lowest power consumption.

RivieraWaves Surf: The high-bandwidth, low-power 802.11ac (1×1 and 2×2) Surf platform is aimed at a vast array of media-sharing consumer devices, including smartphones, tablets, cameras, and smart-home products.

RivieraWaves Stream: The highest performance 802.11ac (up to 4×4), this platform addresses advanced applications including access points, media gateways, and Wi-Fi offload in small cells. The Stream platform is highly flexible and scalable, and offers LTE/LTE-A compatibility in infrastructure applications.


The RivieraWaves Wi-Fi IP family offers designers a choice of small footprint, ultra-low power consumption, high bandwidth, and high performance. Optimized implementations are available that target a broad range of connected devices, including smartphones, wearables, consumer electronics, smart-home, industrial, and automotive applications.
