DNMA-92: 802.11n a/b/g wifi 2x2 mini-PCI module, MB92/AR9220

DNMA-92 is an 802.11n a/b/g wifi 2x2 mini-PCI module designed specifically for directly dual-band (2.4/5GHz) integration on DSL motherboards, easing carrier manufacturer’s design cycles to accelerate time-to-market that demand robust link quality and maximum price/performance ratio. Setting new standards in price/performance ratio, range, reliability, and power consumption, DNMA-92 delivers the ultimate wireless triple play experience for video, voice, and data transmission in the home, for the business, and on the road.  
Atheros AR9220 single-chip and 2 antennas design supports 2 simultaneous traffic MIMO streams using up to 2 integrated Tx and Rx assuring a higher quality experience to enhance user’s satisfaction.

 

 

Key Features
