Ceva has launched its latest RivieraWaves hardware and software IP for WiFi 7 in the next generation of Access Points and metaverse XR headsets.

The RivieraWaves WiFi 7 IP is aimed at high-end consumer and industrial IoT applications including gateways, TVs, set-top-boxes, streaming media devices, AR/VR headsets, personal computing and smartphones.

The IP uses the latest advanced features of the IEEE 802.11be standard, set to be officially approved shortly. The approval will mark the launch of a range of chips for WiFi 7 following several generations of development. According to ABI Research, annual Wi-Fi enabled chipset shipments will exceed 5.1 billion by 2028, with more than 1.7 billion of these chipsets supporting WiFi 7.

With IP for WiFi 4, 5 and 6 over the past decade, Ceva has already established a considerable position in Wi-Fi IP licensing, with more than 40 licensees for its RivieraWaves Wi-Fi 6 IP family, serving a wide range of end markets and applications, from end points to access points, across the IoT.

The RivieraWaves Wi-Fi 7 IP provides a comprehensive 802.11be MAC and PHY solution for integration into the next generation of Wi-Fi SoC products, including headsets for the metaverse.

“The relentless expansion of Wi-Fi usage has pushed the Wi-Fi 7 standard to offer enhanced data throughput, improved latency and support more spectrum in the face of mounting network congestion. Achieving this requires highly complex, cutting-edge functionalities like 4K QAM modulation, Multi Link Operation and Multi Resource Unit to optimize link efficiency across the available bands,” said Tal Shalev, Vice President and General Manager of the Wireless IoT BU at Ceva “Our RivieraWaves Wi-Fi 7 IP platform incorporates all the features of this latest-generation, wireless standard, dramatically simplifying development and time-to-market for companies looking to add Wi-Fi 7 connectivity to their products.”

The 4K QAM modulation scheme used in WiFi 7 is a substantial increase on the previous 1K QAM of WiFi 6, while Multi Link Operation (MLO) introduces dynamic channel aggregation, seamlessly combining heterogenous channels from the same or different bands to navigate interference and boost throughput.

Similarly, Multi Resource Units (MRU) enables the creation of larger channel bandwidths by intelligently stitching together punctured or disjointed Resource Units within the same band. The outcome is not only a remarkable up to five times increase in raw speeds but also significantly reduced latency, thanks to diminished contentions and retries.

The IP also supports 2×2 MU-OFDM(A) transmitter and receiver supporting 802.11be, up to MCS13-2SS and 2×2 MU-MIMO (Multi-user, multiple-input, multiple-output technology) for client-dense environments. There is also beamforming to maximize link budget in multi-antenna systems and full MAC software stack, supporting the latest security standards including WPA3 and China’s WAPI security standard

An Advanced Packet Traffic Arbiter (PTA) functionality allows WiFi and Bluetooth coexistence while a flexible RF interface enables integration with radio circuitry from multiple Ceva partners or licensee’s own radio technology.

The RivieraWaves Wi-Fi 7 IP platform is available now for Access Point applications, with an optimized Station implementation arriving later this year.
