Projectors have made impressive technological advances in recent months. They can now be added to existing networks, they can produce HDTV-quality video, and they are lighter, brighter, and less expensive than the projectors of a year ago. What more could you want? Wireless connectivity, you say? You got it!
Manufacturers like Panasonic, Mitsubishi, Epson, and more have wireless projectors that are available now. Using 802.11b (11 megabits per second) or 802.11g (54 megabits per second) protocol, projectors and computers with compatible wireless cards can communicate without wires.
Wireless full-motion video transmission is currently not possible with wireless projectors because the 802.11b does not provide the bandwidth. However, in the very near future, using the transfer specification 802.11a or 802.11g (54 megabits per second), wireless video may become a reality. This increased level of performance is great news for projector users at home and in the office. At home, new digital cable set-top boxes and gateways, cable modems, satellite receivers, PCs and PDAs are all potential applications for new streaming video technology. HDTV signals can also be supported by the new protocol. In the office, these faster wireless projectors will be able to support multimedia and slide transitions making for more dynamic presentations.
If you are not concerned about projecting wireless video, there are many solutions available today that will fit your wireless needs. InFocus makes their InFocus LiteShow adaptors for a plug-and-play wireless experience that work with many projectors. There are also many projectors that have wireless functionality built-in. Some manufacturers, like Casio, offer a modular solution that will utilize the projectors USB port as both a wireless slot and an option for computerless presenting.
