In the age of quick resolutions for age-old blues, the idea of taking out messy cables as well as the need for easy setup of presentations from various laptops led to the development of wireless projectors. In June 2001 in INFOCOMM, a US-A/V annual trade show in Las Vegas, a wireless presentation was demonstrated by Texas instruments using a PLUS prototype projector, a notebook computer, and a personal digital assistant (PDA) each equipped with WiFi technology. To everyone’s amazement, the presenters were able to launch a PowerPoint presentation delivered wirelessly from a notebook and then a PDA.

Manufacturers clearly believe wireless has a future in projection. The reason could be that there’s been a flood of wireless local area network (LAN) solutions in the PC industry. Most wireless projectors use the WiFi standard. A wireless card compatible with your PC is required to take advantage of this technology. Due to bandwidth

restrictions, wireless projectors are not yet capable of displaying full motion video without reducing frame rate making it unfit for home entertainment.

The lightweight feature of wireless projectors makes it ideal for presentations that need to be constantly on the move. Among the brands that manufacture lightweight wireless projectors are EPSON with its EMP-745 model that weighs only 1.8kg, Benq’s CP120 model with 1500 lumens for brightness (1.3kg), Hitachi’s CP-X268 model with 2500 lumens (3.0kg), Epson EMP-1715 with a brightness of 2700 lumens but weights only 1.7kg. NEC has two models of wireless projectors namely the LT380 model at 3.5kg with a brightness of 3000 lumens and the WT615 model that weighs 6.4kig. at 3500 lumens. Toshiba’s TDP-TW300 is 5.4 kg. at 3000 lumens.

Aside from this line of wireless projectors, ultra-portable projectors have likewise flooded the market. True to its name, they are
