The 802.11ac WiFi standard may sound like an alphabetical step backwards, but for high-bandwidth tasks like 1080p streaming it promises to wipe the face off 802.11n. Qualcomm Atheros wants its share of the billion unit pie and has just launched a series of products to flesh out its 802.11ac ecosystem. Top billing goes to the WCN3680 WiFi/BlueTooth/FM combo module, which plugs into the new Snapdragon S4 (MSM8960) and offers speeds of up to 433Mbps to complement that blistering CPU performance. Since the S4 already includes built-in b/g/n WiFi (not to mention its 3G/4G/LTE baseband), manufacturers who choose to add the 802.11ac component will achieve full WiFi cross-compatibility and make many consumers happy in the process. Meanwhile, you’ll also find similar multilingual abilities in QA’s other 5G WiFi modules for PCs, laptops, routers and enterprise, which are all detailed in the PR after the break. Rest assured that we’ll bring you more hands-on impressions of the latest Snapdragon just as soon as things kick off at MWC — and hopefully in the form of a finished, market-ready tablet or handset.
