Description
Overview
WiFi6 802.11ax 2.5 Gbps HaLow Open WRT WiFi USB Module GAOTek is a highly integrated wireless network router system on chip used for high wireless performance, home entertainment, and home automation and so on. MT7981B is fabricated with advanced silicon process and integrates a Dual-core ARM® Cortex-A53. MPCoreTM operating up to 1.3 GHz and more DRAM bandwidth. This SoC also includes a variety of peripherals, including SGMII, and USB 3.0 (Host) ports. To support popular network applications, MT7981A also implements two 2.5Gbps HSGMII Ethernet interface.MT7981B combines with a RF chip, they can provide dual-band concurrent chipset solution for WIFI6E AX3000 wireless router platform. Besides the connectivity features, the hardware-based NAT engine with QoS embedded in MT7981B transporting the audio/video streams in higher priority than other non-timely services also enriches the home entertainment application. The SFQ separating P2P sessions from audio/video ones so that MT7981B guarantees the streaming service. With the advanced technology and abundant features, MT7981B is well positioned to be the core of next generation Smart WiFi AP router, and home gateway systems. MT7976CN is an IEEE WiFi 6 MIMO RF chip which contains 2.4 GHz WI-Fi transceiver front-ends and 5 GHz WiFi transceiver front-ends.
