WiFi Mini PCIe Module MTK MT7615 4T4R 11ac 1.7Gbps WS3294

WS3294 is a WiFi Mini PCIe Module based on Mediatek MT7615 which is a WiFi Mini PCIe single chip which supports 1733 Mbps PHY rate. It fully complies with IEEE802.11ac and IEEE802.11 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 baseband 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. MT7615 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.

MT7615 supports concurrent dual-band operation at 5GHz and 2.4GHz band (DBDC,Dual-Band-Dual-Concurrent).

With the advent of 802.11ac, multiuser MIMO (MU-MIMO) is defined. MT7615 supports MU-MIMO with different configurations. An AP is able to use its antenna arrays to transmit multiple frames to different clients at the same time and over the same frequency spectrum.
