DR7915

Introduction

DR7915 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.

Application

 

Let's have a look at the screenshots by using Wallys #DR4019 router board plus DR7915 DBDC Wlan module combo.

When the DR7915 is inserted into the DR40X9 board, there are 4 radios that can work at the same time, and it can be used as a soft router

 

As we can see, by using this combo,there will be 4 radios working at the same time,and you can configure each radio into AP or STA mode as you wish.

DR7915 can work on OpenWrt 21.02 version OS directly, no need to install the driver to support this MTK chipset.

We guess it would be a smart option as well to select #DR7915 for applications which require Multi-radios,soft router, Mesh,bonding etc...
