WiFi6 2T2R Dual Bands Dual Concurrent mPCIe Card IEEE802.11ax / ac / a / b / g / n 2.4G / 5GHz MT7915 AW7915-NPD2 with MMCX antenna connectors

AW7915-NPD is 2 RF outputs for 2.4GHz, the other 2 RF outputs for 5GHz, and we combine 1×2.4GHz and 1x5GHz to be 1 antenna outputs and dual bands. So there are 2 antennas MMCX RF outputs with dual bands. In Linux “ifconfig” command, you can see two radios, ra0 and rai0, means you can have two radios in the meantime and dual bands dual concurrent with HW AP mode that can serve for 100+ concurrent clients connected at same time.

The AW7915-NPD is a Wi-Fi 6 Mini PCIe Module with the MediaTek MT7915 DAN chipset, offering 1800 Mbps PHY rate (573+1201) and PCIe 2.1 support. It complies with IEEE 802.11ax/ac standards, featuring 2T2R with 4 RF outputs (2 each for 2.4GHz and 5GHz), which can be configured into 2 dual-band outputs. In Linux, it shows two radios for dual-band concurrent use. The module has an optimized RF design and baseband algorithms for high performance and low power use. Its MAC design offloads Wi-Fi tasks from the host processor, enhancing efficiency. The MT7915 DAN ensures high data throughput, security, quality of service, and meets international standards. Its integrated PCIe interface ensures stable connectivity with the host platform.

The key features of Wi-Fi CERTIFIED 6 work together to ensure that each device on the network is able to function at an optimum level, including legacy devices.

Key capabilities and benefits

• The operation of Wi-Fi 6E in the 6 GHz spectrum offers extremely wide 160 MHz channels and additional capacity, leading to enhanced network performance.
• Orthogonal frequency division multiple access (OFDMA) more efficiently allocates channels, thereby increasing network efficiency and reducing latency for both uplink and downlink traffic in high-demand environments.
• Multi-user multiple input, multiple output (MU-MIMO) allows more uplink and downlink data to be transferred at once and enables an access point to handle a larger number of concurrent clients
• The ability to utilize a 160 MHz channel increases bandwidth, resulting in enhanced performance with minimal latency.
• 1024 quadrature amplitude modulation mode (1024-QAM) enables throughput increases by encoding more data in the same amount of spectrum.
• Transmit beamforming enhances signal power, leading to significantly higher data rates within a specified range.

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.
