Ceva-Waves 802.11ax (Wi-Fi 6) 1x1 & 2x2 MAC & modem

Overview

The Ceva-Waves Wi-Fi IP family offers a comprehensive suite of IPs and platforms for embedding Wi-Fi connectivity into SoCs/ASSPs addressing a broad range of applications.

The Ceva-Waves Wi-Fi 6 IPs are part of the Ceva-Waves Wi-Fi High Performance category, aimed at the vast array of media-sharing consumer devices including smartphones, tablets, cameras and smart home products. These are the industry’s smallest footprint and lowest power but high performance Wi-Fi IPs compliant with 802.11ax (Wi-Fi 6) 1x1 & 2x2.

The Ceva-Waves Wi-Fi 6 IPs consist of 802.11ax MAC and modem, available in both 1x1 SISO and 2x2 MIMO configurations. They are provided with LMAC+UMAC (aka FullMAC) software protocol stacks. They are provided with an integration-ready processor and operating-system- agnostic platform, simplifying deployment in SoC/ASSP designs. The Wi-Fi software protocol stacks can be executed on any processor such as ARM, ARC, Andes, Cortus, RISC-V and others.

The Ceva-Waves Wi-Fi 6 platforms can be used in a standalone single chip or integrated into a bigger System on Chip (SoC) such as application processor, baseband processor, or multistandard wireless combos.

For more comprehensive solution, the Ceva-Waves Wi-Fi 6 IPs are well complemented with Ceva-DSP such as the Ceva-BX1/2, to execute audio processing or other always on sensor hub.

Silicon independent, the Ceva-Waves Wi-Fi 6 IPs support several radio IPs from various partners such as Sirius Wireless. Other RF can be easily supported on customer demand.

Key Features

802.11ax (Wi-Fi 6) MAC:

The Ceva-Waves Wi-Fi 6 MAC core implements the IEEE 802.11a/b/g/n/ac/ax standard with data rates of up to 600Mbit/s for 1x1, and 1200Mbit/s for MIMO 2x2 with 2 spatial streams. It also supports the 802.11e standard (QoS) and the 802.11i standard (Security) extensions.
Ceva's profound expertise in wireless communications resulted in the highly optimized MAC core with special focus on low memory and MIPS requirements while maintaining a small gate count. The MAC core interfaces to the ARM standard AMBA bus.

802.11ax (Wi-Fi 6) Modem:

The Ceva-Waves Wi-Fi 6 hardwired modem cores, available in both 1x1 SISO and 2x2 MIMO configurations are optimized for use with the Ceva-Waves Wi-Fi 6 MAC IP to form high performance and cost effective 802.11ax (Wi-Fi 6) solutions. The supported features are:

Modulation Coding Schemes (MCS) from 0 to 11
20MHz, 40MHz and 80MHz bandwidths
1x1 (SISO) and 2x2 (MIMO) antenna configurations
2x2 (MIMO) with 1 or 2 spatial streams
