WiFi 6 Mediatek MT7915 2T2R Dual Band Concurrent DBDC miniPCIe module IEEE 802.11ax 2.4G / 5GHz AW7915-NPD 524wifi

WiFi6 2T2R Dual Bands Dual Concurrent mPCIe Card IEEE802.11ax / ac / a / b / g / n 2.4G / 5GHz MT7915 AW7915-NPD

AW7915-NPD is a WiFi6 11ax 2T2R 1800Mbps mini PCIe Module by MT7915DAN

AW7915-NPD is 2 RF outputs for 2.4GHz, the other 2 RF outputs for 5GHz, and we combine 1x2.4GHz and 1x5GHz to be 1 antenna outputs and dual bands. So there are 2 antennas RF outputs with dual bands.

AW7915-NPD is a WiFi6 Mini PCIe Module 2T2R based on Mediatek MT7915DAN which is a WiFi Mini PCIe single chip which supports 1800 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. MT7915DAN 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.

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.
