Introduction
Celeno provides high performance Wi-Fi chips and software for HD home networking
applications.
Celeno’s OptimizAir
TM
breakthrough technology enables service providers and consumers
to quickly and simply deploy wireless home networks that can securely deliver multiple
streams of carrier-quality SDTV and HDTV, and any other multimedia content throughout
the home. The Celeno solution is optimized toward uality of Experience ( oE) and
performance consistency in both capacity and coverage.
The Wireless Video Extender (VXT) 1836 solution is a “Celeno-Powered” multi-function
unit – that can be set as an “Access Point” or as a “Station” device. Building a Wireless
Video network requires two or more VXT1836 units communicating with each other -
enabling distribution of high-definition video streams from one central location to a TV set
in the house without replacing existing routers, gateways, set-top boxes or laying out new
cables across the house.
Your Wireless Video Extender unit may be used as a:
• Wireless Video Extender Access Point (AP) ()
i.e. connected to home gateway or cable/DSL modem
• Wireless Video Extender Station (STA) ()
i.e. connected to set-top box or media storage/player
Please Note:
A minimum of two units are required to establish a wireless video extender network
• One unit should be configured as an Access Point
• One or more units configured as Stations can be associated with the wireless video
extender AP
