The MT7601U is a highly integrated Wi-A single chip which supports 150 Mbps
PHY rate It fully complies with IEEE 802.11n and IEEE 802.11 b/g 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 DMA engine and
hardware data processing accelerators which offloads the host processor.
The M17601U 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.
