InFocus Unveils Wireless Projection Technology

InFocus recently unveiled new technology that aims to sever the cord between computer and projector.

According to information released by the company last week, it's partnered with technology developer Wisair to deliver a solution that couples DisplayLink technology with a wireless USB solution to deliver wireless video.

DisplayLink technology uses a computer's USB port to deliver the video signal to the projector. It's a fairly new technology as far as projectors are concerned, one that made its debut as an embedded technology in a projector just back in June 2008, although it had been in use in other display technologies before then. DisplayLink is cross-platform solution that is designed to eliminate the need for multiple display interfaces, standardizing on USB 2.0, with support for 32-bit graphics at resolutions up to 2,048 x 1,152 using DL2 or DL2+ adaptive compression.

The new solution that InFocus has debuted takes this concept a step further, using USB adapters to send the display signal wirelessly. According to InFocus, the technology supports 99 Mbps data rates using AES-128 encryption and allows users to connect at distances up to 30 feet. The system includes pre-paired adapters (one for the projector and one for the computer), with a preinstalled driver on the PC adapter to speed installation. The solution sets up a pre-configured, self-contained network, preventing the transmitted data from clogging up an organization's main wireless network. The technology also supports the InFocus DisplayLink Manager, which allows users to control the projector remotely. It supports resolutions from SVGA (800 x 600) up to WXGA+ (1,440 x 900).

The technology is not available immediately for all of InFocus' projectors. It currently supports only the InFocus IN1100 and IN3100 series. But the company said support will be expanded in the near future to the IN1500, IN5300 and IN5500 series. Future DisplayLink-based models will also support the technology.

Wireless DisplayLink starts at $159 per unit. At present it is only available for Windows XP SP2 and Windows Vista (32-bit), according to InFocus' support site. Further information can be found here.
