Ensigma Wi-Fi Connectivity Family

IEEE 802.11ac Wi-Fi

The Ensigma IEEE 802.11ac Wi-Fi IP is provides a highly flexible, dual-band Wi-Fi solution that is capable of supporting up to IEEE 802.11ac 2×2 MIMO and provides a complete physical and MAC layer. It uses a hardware and software framework which is combined with hardware accelerators and a high-speed flexible DMA fabric to provide a complete and highly optimised, yet flexible IEEE 802.11ac IP solution.
