Wireless teknologier erobrer hjemmet

Ifølge analysefirmaet IMS vil den installerede base af trådløse home networks vokse med næsten 300 procent i løbet af de næste fem år (in english).

From under 70 million at the end of 2012, the number of households worldwide deploying no-new-wire technologies will surge to more than 250 million at the end of 2017, led by technologies such as HomePlug and MoCA.
 
No-new-wire technologies use as a communications medium the existing wiring present in consumers’ homes, such as powerlines, coaxial cables and twisted pair cables. Utilizing the existing wired infrastructure significantly reduces cost and simplifies the installation of wired home networks. A variety of no-new-wire technologies exist, with HomePlug focusing on powerline and MoCA on coaxial cables. Another, G.hn, is attempting to unify all three types of wiring.
 
- The uptake of no-new-wire technologies is driven by the need to share an Internet connection with devices that may not include wireless connectivity, the need to extend an existing home network and eliminate areas of poor coverage, as well as the need for increased bandwidth, says Liam Quirke, senior analyst for connectivity at IHS.
- In particular, growth in Internet Protocol and multiroom television services is projected to increase demand for no-new-wire technologies, as these services place a greater strain on network bandwidth.
 
Even so, the increased prevalence of no-new-wire networking technologies is not expected to come at the expense of Wi-Fi.
- Wi-Fi provides the mobility desired by consumers when connecting devices such as laptops, tablets or smartphones to their home network. To this end, Wi-Fi will continue to adequately facilitate the wireless transmission of data between these devices and the home network, adds Quirke.
 
No-new-wire technologies are seen as complementary to the use of Wi-Fi within the home, providing higher-bandwidth networking connectivity to static devices, often used to enable services centered on video streaming.

To-date, HomePlug and MoCA have demonstrated the highest adoption of the different no-new-wire standards, with the former enjoying the most success in Europe and the latter in North America. However, the first G.hn-certified chipset was announced in the fourth quarter of last year, and ZTE of China recently announced it would incorporate the technology in a series of powerline network adapters.
 
Whilst G.hn’s level of success remains uncertain, one thing is certain: the market for no-new-wire networking technologies is poised to continue its evolution.
 
The findings in this release are taken from the IHS study 'Home Networks and Residential Gateways – World – 2013'. The study analyzes the market for home networks by technology, region, country and type, in addition to presenting statistics on variables such as households receiving broadband and digital television services; the shipments of consumer premises equipment (CPE); and market share for CPE suppliers as well as no-new-wire IC suppliers. Covering the period from 2011 to 2017, the report also examines the current state of the market and provides forecasts on how the market is projected to evolve.
