MT7915DAN is designed to support high data throughput over WiFi. The host interface PCIe are integrated to provide stable bandwidth between the host platform and MT7915DAN.

Deep sleep mode:

Multiple power domains are implement on chip. In deep sleep mode, the PMU could be configured in a low power state to save the power consumption.

Two CPU systems: There are both 32-bits RISC MCU subsystem. The CPU has its local memory. There are several options of clock frequency to provide the optimal performance with the best power consumption. The 32-bit RISC MCU is used to do clocck control, power management, and host interface configuration. PDMA (packet DMA) engines are integrated to support on-the-fly data buffer management.

MT7915AN had the WiFi MAC and BBP subsystem and use with MT7975DN together, which provide the best-in-class radio and low power performance. And the Wi-Fi MAC and BBP subsystem and use with MT7975DN together, which provide the best-in-class radio and low power performance.

With the advent of 802.11ax/ac, multi-user MIMO (MU-MIMO) is defined. MT7915DAN supports MU-MIMO with different configurations.

  1. 11ax performance test Review by Bruno

    Value

    We have concluded the tests using the ARM based board and were able to get around 800 Mbit/s with an MCS between 10 and 11 (1020.8 to 1134.3 Mbit/s). I think this value is more of what we expected. This board runs Ubuntu 20.04.4 LTS with a compiled kernel.
    Thanks for the support. (Posted on 6/2/2022)
