元器件交易网讯 5月7日消息，据外媒报道，调查机构ABI认为，Wi-Fi已经成为互联网接入的主导技术，今年将有超过26亿Wi-Fi芯片组出货。未来五年内Wi-Fi芯片出货量将飙升至180亿。

　　“2019年不同层次的Wi-Fi芯片将呈现出巨大分化，”ABI的研究主管菲利普·索利斯表示，“独立或分立Wi-Fi芯片将越来越多的转向物联网，同时物联网也成为最大的应用领域。”

　　2019年装载有Wi-Fi功能的产品出货量将超过30亿，智能手机占据最大比重。

　　索利斯表示：“802.11ax将进一步最大限度地利用未使用的5GHz频谱，从本质上看802.11ax是802.11ac Wave 2的更好版本，允许更高的数据传输速率。这将为家庭Wi-Fi的增长提供技术支持。”（元器件交易网毛毛  摘译）

　　Wi-Fi chipset shipment heads for an 18billion gain

　　Wi-Fi dominates wireless connectivity asthe most ubiquitous technology for Internet access, with over 2.6 billionchipsets slated to be shipped this year, according to ABI Research. It hasevolved and continuously so, adapting and expanding with new protocols such as802.11ac, 802.11ax, 802.11ad (WiGig), and Wi-Fi Direct. In the next five years,Wi-Fi chipset shipment is thus predicted to soar to 18 billion.

　　"There will be a roughly even split in2019 for Wi-Fi chipsets of different integration levels," said researchdirector Philip Solis of ABI Research. "Standalone, or discrete, Wi-Fichipsets – increasingly targeting the Internet of Things – will be the largestgroup, followed by integrated platforms with Wi-Fi targeting mobile devices,followed by Wi-Fi combo chipsets."

　　Wi-Fi protocols will catch up as well. Bythe end of the forecast period, dual-band 802.11n/802.11ac is expected tocomprise the vast majority of chipsets shipped among all the protocols. Theprotocol had a strong start in 2013 by surpassing 100 million shipments in thesmartphone space alone, accounting for a sizable fraction of the totalshipment. Tri-band 802.11n/802.11ac/802.11ad shipments will also experiencegrowth in the next five years.

　　Meanwhile, Wi-Fi Direct-enabled products willsurpass the three billion shipment ceiling in 2019 with the highest attachrates in ultraportable PCs media tablets, and traditional laptops. However, thelargest category of Wi-Fi Direct-enabled products in terms of units shippedwill be smartphones.

　　"Even as the industry starts to movethis year from 802.11ac Wave 1 to Wave 2 chipsets that can support largerchannels and MU-MIMO, Wi-Fi's evolution will not stop there. Aside from thisshift and pairing Wi-Fi with WiGig (802.11ad), 802.11ax will start replacing802.11ac towards the end of the forecast period," added Solis."802.11ax will further maximise efficient use of 5GHz spectrum byutilising unused chunks of spectrum, even coordinating this with other nearbyaccess points. Essentially, 802.11ax will be a better version of 802.11ac Wave2 that will allow for even greater data rates. The proliferation of Wi-Fi inthe home will be supported by the technology's continued evolution."
