The improved effectiveness of PC-based collaborative activities afforded by wireless projectors in turn improves projector ROI. One advantage of wireless projectors on your network is that they allow multiple PCs to connect to one projector or for one or more PCs to use multiple projectors. So, consider the bandwidth needs of your presentation before cutting the cord to your projector completely.

It remains for the emerging 802.11a, 20-25 MHz, standard to support high-speed animation and limited video, and eventually, 802.11g at 54 MHz, to provide the bandwidth needed for full motion video. Yet the 802.11b version, at 11 MHz, supports at best very limited PowerPoint animations.
Wi-Fi provides better range and bandwidth, up to 150 feet depending on the required bandwidth. Virtually all wireless projectors today use Wi-Fi connectivity, although some Bluetooth models made it to market before Wi-Fi - the IEEE 802.11b WLAN standard - became widespread. However, wireless projectors are not without their limitations. The presenter can actually move anywhere in the room when using a PDA or notebook with built-in wireless capability.

In a typical business meeting the presenter is free to move about and is no longer tethered to the PC or projector. The projector is wirelessly controlled and display data is received wirelessly over the network via any type of PC, from handheld to desktop to remote server. Basically, the projector comes with a built-in wireless LAN or socket for a WLAN card. Since they first appeared on the market in mid-2001, wireless projectors are making regular appearances in new product announcements from manufacturers such as Epson America, InFocus, NEC USA, Matsushita Electronic, Sony Electronics e-solutions and Toshiba.įirst, let's consider how all this works. But there is a new trend in projection systems that will make you sit up and take notice: projectors that connect wirelessly to a PC. While it's the projected video and graphic images that is meant to grab your attention, the projectors themselves usually go unnoticed.
