DNXA-116 is an 802.11n a/b/g wifi 2x2 in the smallest PCIe half-mini card interface designed to propel the industry forwarding and diverse needs of both consumer and enterprise applications. Atheros’ Signal-Sustain Technology (SST) enhances rate-over-range performance to reach an impressive increase in rate-over-range of ~+100% at short range, ~+50% at mid range and ~+25% at long range.

Despite its mighty performance, DNXA-116 consumes even less power in every operation mode – active TX, active RX, idle associated and sleep than the previous generation solution. It keeps the notebook and other computing platforms running much longer on a single battery-charge, while providing TCP throughput of more than 200 Mbps when used in 2x2 mode. Atheros’ Fast Channel Switch (FCS) reduces the channel switching time between the 2.4 GHz and 5 GHz bands from 10 ms to as little as 1 ms. Setting new standards in throughput, range, reliability, and power consumption, DNXA-116 delivers the ultimate wireless triple play experience for video, voice, and data transmission in the home, for the business, and on the road.

  • The smallest dual-band PCIe interface in 2Tx/2Rx design is ideal for embedding into ultra-compact devices or embed additional mini cards with complimentary technologies.
  • Dual band 802.11 a/b/g/n supports 2Tx/2Rx 2-stream MIMO to enable PHY data rate up to 300Mbps link rate for 40MHz channel, six times the throughput of 802.11a and 802.11g.
  • Atheros’ Fast Channel Switch (FCS) reduces the channel switching time between the 2.4 GHz and 5 GHz bands from 10 ms to as little as 1 ms.
  • Signal-Sustain Technology (SST) increases rate-over-range ~+100% at short range, ~+50% at mid. range, and ~+25% at long range.
  • Dynamic MIMO Power Save supports 1x1 downshift to lower power consumption. 
  • Supports 5/10/20/40MHz channel to maximize bandwidth efficiency.
