Qualcomm Atheros is a developer of semiconductors for network communications, particularly wireless chipsets. Founded under the name T-Span Systems in 1998 by experts in signal processing and VLSI design from Stanford University, the University of California, Berkeley and private industry. The company was renamed Atheros Communications in 2000 and it completed an initial public offering in February 2004 trading on NASDAQ under the symbol ATHR.

On January 5, 2011, it was announced that Qualcomm had agreed to a takeover of the company for a valuation of US$3.7 billion. When the acquisition was completed on May 24, 2011, Atheros became a subsidiary of Qualcomm operating under the name Qualcomm Atheros.

Qualcomm Atheros chipsets for the IEEE 802.11 standard of wireless networking are used by over 30 different wireless device manufacturers.

In January 2011, Qualcomm agreed to acquire Atheros at $45 per share cash. This agreement was subject to shareholder regulatory approvals. In May 2011, Qualcomm completed its acquisition of Atheros Communications for a total of US$3.7 billion. Atheros became a subsidiary of Qualcomm under the name Qualcomm Atheros.

After the acquisition, the division unveiled the WCN3660 Combo Chip, which integrated dual-band Wi-Fi, Bluetooth, and FM into Qualcomm Snapdragon mobile processors. Qualcomm Atheros launched the Skifta media shifting application for Android and released the first HomePlug Green PHY solution at the end of the year.

In 2012, Qualcomm Atheros announced a Wi-Fi Display product at CES 2012, along with a new chip for HomePlug AV power line networking. At Mobile World Congress 2012, Qualcomm Atheros demonstrated a suite of 802.11ac enabled products. This included the WCN3680, a mobile 802.11ac combo chip targeting smartphones and tablets. In June 2012 at Computex, Qualcomm Atheros added new 802.11ac products.
