Embeddable IP enables Wi-Fi 7 connectivity

Ceva is bolstering its RivieraWaves portfolio of wireless connectivity IP with Wi-Fi 7 IP for high-end consumer and industrial IoT applications. Incorporating both PHY and MAC functions, the Wi-Fi 7 IP is available now for access points, with an optimized station implementation slated for later this year.

The embeddable IP leverages the key features of the IEEE 802.11be standard, including 4K quadrature amplitude modulation (QAM), multi-link operation (MLO), and multiple resource units (MRUs). 4K QAM provides a substantial increase in throughput compared to the 1K QAM of Wi-Fi 6. MLO introduces dynamic channel aggregation, seamlessly combining heterogeneous channels from the same or different bands to navigate interference and boost throughput. MRU stitches together punctured or disjointed resource units within the same band to increase throughput and reduce latency.

Other features of the RivieraWaves Wi-Fi 7 IP include:

  • 2×2 MU-OFDM(A) transmitter and receiver supporting 802.11be, up to MCS13-2SS
  • 2×2 MU-MIMO for client-dense environments
  • Beamforming to maximize link budget in multi-antenna systems
  • Full MAC software stack, supporting the latest security standards including WPA3 and China’s WAPI
  • Compatible with the EasyMesh standard for interconnectivity between different APs
  • Advanced Packet Traffic Arbiter (PTA) functionality for Wi-Fi & Bluetooth connectivity coexistence

RivieraWaves Wi-Fi 7 IP is backward-compatible with previous Wi-Fi generations. It employs a flexible RF interface that enables integration with radio circuitry from multiple Ceva partners or a licensee’s own radio technology.
