Research reports released this week are predicting the end of wired Ethernet, and the end of Wi-Fi networking. In the second of a two-part report, The Bunton Group predicts that wired Ethernet services will be replaced by the emerging 802.11n standard, which will make noticeable gains in the wired Ethernet market by 2010. The report counsels networking professionals to begin planning now for the deployment and maintenance of an all-wireless network.

The prediction does not apply to core network infrastructure, such as switches, routers and data center equipment, end users will access network services exclusively via wireless in the future. The report categorized 802.11n as the "preferred and dominant" wireless LAN standard. Citing employee mobility as the primary driver for the trend, the report indicates that 802.11n should receive thorough consideration in circumstances where FE speeds are acceptable, and when a VoIP deployment is underway.

At the same time, a new In-Stat report indicates that growth in the Wi-Fi mesh networking equipment market is slowing. The market, which experienced 100 percent shipment growth in 2006 will register only 90 percent growth in 2007 and will experience sharp declines in growth starting in 2009.

The rate of new deployments of municipal Wi-Fi networks will slow, amid concerns over the business models used to support the network. In most cases, consumer subscription rates will not generate enough revenue to support the network. Additionally, large-scale Wi-Fi will face stiff competition from WiMAX and cellular networks. In the longer term, WiMAX is shaping up to be a better option for broad coverage, and for delivering connectivity into hard-to-serve areas, since it can reach farther without repeater support. Cellular networks are developing innovative services for wireless users, and are now beginning to offer hybrid network connectivity that allows users to switch from Wi-Fi to cellular network support instantaneously.
