Description

The Oolite V8.2 module use the MT7621A as main chip, MT7975DN and MT7905DAN WiFi 6 WLAN chip Composition of dual frequency WiFi 6 module solution.

The MT7621A integrates a dual-core MIPS1004Kc (880MHz), HNAT/HQoS/ Samba/ VPN accelerators, 5-port GbE switch, RGMII, USB3.0, USB2.0, 3xPCIe, SD-XC. The powerful CPU with rich portfolio is suitable for 802.11ac, LTE
cat4/5, edge, hotspot, VPN, AC (Access Control). It can also connect to touch- panel, ZigBee/Z-Wave for Internet Service Router and Home Security Gateway.

The MT7975DN is an IEEE 802.11ax 2×2 A-band + 2×2 G-band MIMO and Wi-Fi/BT 2-in-1 chip which contains 2.4 GHz WI-Fi transceiver front-ends, 5 GHz Wi-Fi transceiver front-ends, and a Bluetooth transceiver front-end in a DRQFN package. Dedicated Dynamic Frequency Selection (DFS) and Spectrum Monitor (SM) receivers are included to support coexist with 5GHz radar or other 2.4G WIFI systems.

The MT7905DAN is a highly integrated Wi-Fi A/D chip which supports 573+1201 Mbps PHY rate. It fully complies with IEEE 802.11ax and backward compatible with IEEE 802.11 a/b/g/n/ac standards, offering feature-rich wireless
connectivity at high standards, and delivering reliable, cost effective throughput from an extended distance.

For the next generation router, MT7621AT provides several dedicated hardware engines to accelerate the NAT, QoS, Samba and VPN traffic. These accelerators relief the CPU for other upper layer applications.
