Cut the Classroom Cord
Schools attempting to wire older classrooms for projectors or large screen monitors over the summer are faced with one big problem: the cables for video and audio never seem to be where they need to be. Rewiring a classroom can easily dwarf the cost of the projector, but Warpia lets you unwire it by connecting any recent PC with a projector or TV with no fuss, muss or wires.
Warpia’s USB PC to TV Audio/Video Display Adapter SWP100a is a little long-winded but can link a PC to a monitor, TV or projector in a classroom wirelessly. Based on the USB Wireless 1.0 standard, Warpia takes advantage of Wisair’s WSR 601 chip to stream high-quality audio and video over thin air.
Warpia comes with a small USB radio that’s the size of a memory key and transmits whatever is on the host PC’s screen. The larger receiver goes near the projector and its radio can be aimed the received vertically or horizontally. There’s also an AC adapter for the receiver and a CD of software.
The system can handle resolutions up to 1,400 by 1,050 in 32-bit color and CD-quality audio. On the downside, At the moment Warpia is for PCs only and will work on neither Macs nor Linux computers. There is beta software for Macs that can be downloaded.
The way it works is that the teacher’s computer uses Warpia to send an audio-video stream over a wireless link in the 3.2- to 4.8GHz range. With 128-bit AES encrypted security, adjacent classrooms won’t interfere with each other. As data moves through the system, a green light blinks on both the sender and receiver.
