CEVA, Inc. unveiled the RivieraWaves Wi-Fi IP platforms addressing the growing need to integrate Wi-Fi 802.11a/b/g/n/ac into a new class of SoCs, targeting smartphones, wearables, consumer electronics, smart home, industrial and automotive applications.
The RivieraWaves Wi-Fi IP platforms support a host of advanced features, including Beam Forming, Multi-User MIMO (Wave 2), Space-Time Block Code (STBC), Low Density Parity Check (LDPC), Dynamic Bandwidth Management, Wi-Fi Direct and WAPI.
The RivieraWaves Wi-Fi platforms incorporate a flexible RF interface to accommodate each customer's selected RF solution. In addition, CEVA has partnered with RF IP providers including, Catena, Maxscend and others to offer low power RF solutions that are fully validated with the Wi-Fi platforms. These RF IPs are available in a number of different foundries and process nodes, offering customers a broad choice of RF options for their specific requirements.
For customers also requiring Bluetooth connectivity, RivieraWaves Bluetooth 4.2 IP can be seamlessly integrated, along with a smart co-existence interface which handles Wi-Fi/Bluetooth traffic arbitration to avoid interference, further simplifying the overall system design.
Each of the RivieraWaves Wi-Fi platforms incorporates the Upper MAC (UMAC), Lower MAC (LMAC) and PHY modem functions. For ease of deployment, the UMAC and LMAC software stacks are processor and operating system agnostic. The modem can be provided either as a hardwired function or as a software defined modem. The hardwired modem is optimized for cost-effective Wi-Fi solution for any connected device, while the software defined modem provides the extra flexibility required in some multi-protocol connected devices.
Each of the RivieraWaves Wi-Fi platforms is specifically tailored to address differing market requirements:
- RivieraWaves Sense- small footprint and low-power 802.11n (802.11ah on the horizon) Wi-Fi IP, has leveraged on RivieraWaves low power design methodology, enabling device operation for years on a single AA battery.
- RivieraWaves Surf- high bandwidth 802.11ac 1×1 and 2×2 Wi-Fi IPs, aims at a vast array of smart consumer devices including smartphones, tablets, the smart home, surveillance cameras and more. Leveraging RivieraWaves Surf, customers can design a complete 802.11ac 1×1 solution that consumes less power than any Wi-Fi 802.11n solution from competition.
- RivieraWaves Stream- high performance 802.11ac up to 4×4, addressing the most advanced use cases including access points, media gateways and Wi-Fi offload in small cells. Enabled by the processing power of the CEVA-XC DSP, RivieraWaves Stream is scalable to address up to several hundreds of users and offers a unified platform for co-existence with LTE/LTE-A cellular networks. RivieraWaves Stream allows customers to design a complete 802.11ac 4×4 solution that consumes less than 3.5W peak including RF and PA.
