WiFi6 4T4R Dual Bands Selectable mPCIe Card IEEE802.11ax / ac / a / b / g / n 2.4G / 5GHz MT7915 AW7915-NP1

AW7915-NP1 is a WiFi6 11ax 4T4R 2401Mbps mini PCIe Module by MT7915.

FCC ID: TKZAW7915NP1
CE IC certificated

AW7915-NP1 is a WiFi6 Mini PCIe Module 4T4R based on Mediatek MT7915AN which is a WiFi Mini PCIe single chip which supports 2401 Mbps PHY rate with  PCIe2.1. It fully complies with IEEE 802.11ax/ac and IEEE 802.11 ac/a/b/g/n standards, offering feature-rich wireless connectivity at high standards, and delivering reliable, cost-effective throughput from an extended distance.

Optimized RF architecture and base band algorithms provide superb performance and low power consumption. Intelligent MAC design deploys a high efficient offload engine and hardware data processing accelerators which completely offloads Wi-Fi task of the host processor. MT7915AN is designed to support standard based features in the areas of security, quality of service and international regulations, giving end users the greatest performance any time and in any circumstance.

MT7915AN is designed to support high data throughput over WiFi. The host interface PCIe are integrated to provide stable bandwidth between the host platform and MT7915AN.

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 MT7975N together, which provide the best-in-class radio and low power performance. And the Wi-Fi MAC and BBP subsystem and use with MT7975N 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. MT7915AN supports MU-MIMO with different configurations.
