Qualcomm’s “gigabit Wi-Fi” play for smartphones

Qualcomm confirmed it will introduce so-called gigabit Wi-Fi -- 802.11ac -- by pairing it first with its high-end mobile system-on-chip, the Snapdragon 800, set to appear in premium smartphones starting in the second half of 2013, according to a Qualcomm executive.

The single-stream Atheros WCN3680 is a combination chip that includes 11ac, Bluetooth 4.0 and FM radio. In June, Qualcomm announced its portfolio of planned 11ac products. The single-stream chipset has a data rate of 433Mbps and throughput of about 200Mbps. In January, the chipmaker unveiled the high-end of its newest Snapdragon processors, with the 800 series targeted at top-of-the-line devices. The just-announced 200 and 400 series are aimed at low-to-mid tier devices.
