Projectors are often used in glamorous home theatre installations, in pubs and clubs to display the football on and at glitzy launch events to display new products in large scale on the wall. But there's a far more staid side to these workhorse products: more often they're to be found installed in classrooms and boardrooms, carrying out the mundane task of informing and educating. It's a job they're supremely well suited to, allowing the display of huge screens without much bulk, weight or installation effort required.
The problem with installation projectors such as these, especially those in meeting rooms, is that, unless you prepare yourself well in advance, chances are you'll not know where to plug your laptop in or how to set the projector up when you get there. And if you work in a classroom, the input cable might simply be in the wrong place for your needs. That's where wireless projection technologies, and the Infocus LiteShow II comes in. Matched here with the new business-specific IN35W projector, it allows you to forget about the VGA cable and instead project your presentation directly over a Wi-Fi link.
It sounds like a brilliant idea, but the first time I came across wireless projection I was pretty underwhelmed. Infocus' first LiteShow product was 802.11b, wasn't particularly straightforward to set up, and when connected the on-screen response was sluggish and the limited bandwidth cut video playback out of the equation entirely.
More recently, however, things have been looking up for wireless projection. The Taxan KG-PS125X impressed me with its SDIO-card wireless solution, and now it's the turn of Infocus' second LiteShow product. It certainly does a better job than its predecessor. The module itself is more bulky - more like a wireless router than the M1-DA dongle of the previous version - but its 802.11g wireless connectivity means that it's a far more usable product.
