Wi-Fi IP platforms address connected devices for the IoT
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:
-
RivieraWaves Sense is claimed to be the smallest footprint and lowest power 802.11n (802.11ah on the horizon) Wi-Fi IP targeting wearables, medical, wireless audio and other Internet of Things (IoT) devices. Leveraging on RivieraWaves low-power design methodology, RivieraWaves Sense enabled devices are capable of operating for years on a single AA battery.
-
RivieraWaves Surf comprises high-bandwidth 802.11ac 1×1 and 2×2 Wi-Fi IPs aimed at a vast array of smart consumer devices including smartphones, tablets, the smart home, surveillance cameras and more.
-
RivieraWaves Stream is the highest 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 3.5 W peak including RF and PA.
Aviv Malinovitch, vice president and general manager of CEVA’s Connectivity business unit, stated: "Our RivieraWaves Wi-Fi IPs substantially reduce the entry barrier for customers requiring leading-edge 802.11 connectivity in their SoC designs. We have already signed up customers for all three platforms, taking advantage of our hardware and software integration and system expertize to develop low-power Wi-Fi enabled products, quickly and efficiently."
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 (SDM).
The hardwired modem implementation is fully optimized for minimal die area and extremely low power consumption, resulting in a truly cost-effective Wi-Fi for any connected device. The software defined modem flavor provides the extra flexibility required in some multi-protocol connected devices and leverages the comprehensive portfolio of CEVA DSP cores and software to create an application-specific system matched to the customer’s requirements.
The RivieraWaves Wi-Fi platforms incorporate a flexible RF interface to accommodate each customer’s selected RF. In addition, CEVA has partnered with RF IP providers including, Catena, Maxscend and others to offer low power RF that is 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.
