Based upon the results of our North American broadband survey, the majority of consumers with a home network that use Wi-Fi are still not very/not at all familiar with the benefits and differences between 802.11g and 802.11n. Although this may limit upgrades in the short term, the older Wi-Fi standards will be discontinued eventually anyway. Other wired technologies that use coax, phone wiring, and powerline are also beginning to make strides with telcos deploying telco TV services.

The number of home LAN physical layer interface shipments will surpass 500 million in 2010, and the installed base of home networks will surpass 300 million in 2011.

Global and regional forecasts are provided for home networks, with North America, Europe, and Asia/Pacific broken down by use of Ethernet, Gigabit Ethernet, 802.11a, 802.11b, 802.11g, 802.11n, and other wired solutions. In addition, global home network interfaces by physical layer are included, since the majority of network-enabled devices have both wired and wireless connectivity options.

より高速な無線規格がホームネットワーキングで名を上げる

アリゾナ州スコッツデール、2009年9月9日
ホームネットワーク利用者は、ギガビットイーサネットや802.11nや、同軸ケーブル、電力線、電話線などの有線技術など、より新しく高速な接続性を追い求めていると米国調査会社インスタット社は報告している。2008年にはまだ、世界のホームネットワークの利用では、10/100のイーサネット技術が主流だった。しかし2009年末には、802.11xネットワークが10/100イーサネットの数を上回るだろうと、米国調査会社インスタット社は報告している。また、多くのWi-Fi利用者が、802.11bからより強固な802.11gに移行し、または移行しつつあり、802.11gからドラフト版の802.11nコンパチブル製品にアップグレードする人も出始めた。

「この他の注目すべき傾向としては、ホームネットワーク利用を単なるインターネット共有だけに利用しているわけではないとする北米ユーザの割合が、2008年の41.8%から2009年には49.7%まで増加したということである。しかし、多くのユーザは、家電をネットワークに接続して、PCと家電製品の世界をつなぐことはしていない」とインスタット社のアナリストJoyce Putscher氏は語る。

インスタット社は、下記についても調査した。

• 世界のホームネットワーク導入数は、2011年に3億を上回るだろう
• Gigabitイーサネットによるホームネットワークは、2013年には世界で約9000万、4倍以上に増加するだろう
• 2012年までのWi-Fiホームネットワーク普及は、アジア太平洋地域がリードするだろう
• 有線技術によるネットワーク接続世帯数においては、現在も予測期間中も欧州が優勢だろう

インスタット社の調査レポート「ホームネットワーク技術と接続サービス利用状況調査:イーサネット、802.11、同軸ケーブル、電力線 - Home Network Technology & Connectivity Use: Ethernet, 802.11, Coax, and Powerline」は、世界のホームネットワーキング市場を調査した。2013年までの技術毎/地域毎のホームネットワーク普及数予測(イーサネット10/100、ギガビットイーサネット、規格毎のWi-Fi、同軸ケーブル、電話線、電力線)、それぞれのホームネットワーキング技術とアプリケーションに関する消費者の認知度と需要、2013年までのLAN物理レイヤーネットワーキングインターフェース出荷数予測、ホームネットワーキング技術と市場の傾向分析を記載している。

Faster Wireless Standard Making Mark in Home Networking

SCOTTSDALE, Ariz., September 9, 2009 - Home network users are continuing to migrate to newer and faster home networking connectivity technologies, including Gigabit Ethernet, 802.11n and alternative wire technologies, such as coax, powerline and phone wiring. In 2008, 10/100 Ethernet was still the leading technology in use with home networks worldwide.  However, 802.11x networks will outnumber 10/100 Ethernet by the end of 2009, reports In-Stat. In addition, many Wi-Fi users have transitioned (or are transitioning) from 802.11b to the more robust 802.11g, and some have begun to upgrade from 802.11g to draft 802.11n-compatible products.

“Another notable trend is that the use of home networks for more than just Internet sharing among North American users increased from 41.8% in 2008 to 49.7% in 2009,” says Joyce Putscher, In-Stat analyst. “But most consumers have not yet bridged the chasm between the PC and consumer electronics (CE) worlds by adding CE devices to their networks.”

Recent research by In-Stat found the following:

• Worldwide installed home networks will surpass 300 million households in 2011.
• Home networks with Gigabit Ethernet will more than quadruple through 2013 to nearly 90 million households worldwide.
• Asia/Pacific will lead in Wi-Fi home network penetration by 2012.
• Europe leads in networked households with alternative wire technologies, both currently and throughout the forecast period.

Recent In-Stat research, Home Network Technology & Connectivity Use: Ethernet, 802.11, Coax, and Powerline (#IN0904631RC), covers the worldwide market for home networking. It includes:

• Forecasts for installed home networks by technology for each region through 2013, including segmentation for Ethernet 10/100, Gigabit Ethernet, Wi-Fi by Standard, Coax or Phone Wiring, and Powerline.
• Consumer awareness and demand of different home networking technologies and applications.
• Forecasts for LAN physical layer networking interface shipments through 2013.
• Analysis of trends in home networking technology and markets.
