First Look: Big-Screen Wi-Fi

By Eric Griffith

NEC Solutions America, Visual Systems Division, has announced a series of new projectors due in the fall of 2002 that will all incorporate 802.11b networking for easy connections with any wireless PC filled with presentations.

The DLP-based LT220, LT240 and LT260 projectors, part of NECs portable line (each is only 6.5 lbs), as well as the higher-end, LCD-based MT1060 and MT1065, will use ImageXpressT, a technology for continuous communication between the projector and a PC, either via 10BaseT or Wi-Fi. With the wireless, multiple laptops can have presentations ready and there’s one touch switching between computers.

Visually, the new LT series projectors will feature NEC proprietary technology for getting a square picture. The optical unit is sealed, so even using it in a dusty environment like a classroom may mean fewer cleanings. The units differ in the amount of light they project (from 1500 to 2100 ANSI lumens) and resolution (either XGA or SVGA). Pricing has not yet been set on the projectors.

The MT projectors are larger at 12 lbs and have a brightness ratings of 2300 and 3000 ANSI lumens. Both support XGA resolution (1024 x 768).

NEC is not the first to put 802.11b into projectors: networking company Linksys recently announced a Wireless Presentation Gateway (WPG11) to help get PowerPoint users up and running with any networkable projector. .
