Wireless devices are very popular nowadays - you can find that almost everyone is using something without wires in everyday life, from Bluetooth-connected mouse or keyboard for PC or tablet to wireless chargers for smartphones and even TVs connected to Wi-Fi. So it’s no wonder that such a common thing nowadays like projectors are working well without the need for a wired connection. Those devices are very useful almost everywhere, from schools and offices to home cinemas due to the absence of any wires other than the power cable.
If you’re really interested, you can find a lot of useful info about such projectors all over the Internet. For example, you can read an article by Jack Herer which he posted at the site ProjectorExpo. Meanwhile we’ll give you a summary on various wireless projectors, ways of using those devices and, of course, we’ll also throw a short look at the technology itself to give you a basic knowledge about it.
Various ways of using wireless projectors
Video projectors, obviously, are devices which are used to project an image or a video onto a specific large surface, oftenly a screen. Those devices are very useful for organizing home theaters and for presentations in conference rooms. And when wireless projectors using Wi-Fi to provide remote access and remote control over the network were created, such devices fastly became very popular among different people.
Projectors with wireless connection capabilities are used for a wide range of activities and in a vast variety of places. From simple movie watching and viewing office presentations to even gaming. Just the same as wired counterparts though, yet having a major advantage - only one wire for power supply and nothing more. No VGA (D-Sub), SVGA DisplayPort, HDMI or anything else. and you can even translate images and videos from your mobile devices like tablets and smartphones.
How wireless projectors are working?
Wi-Fi connected projectors in general are just the same as their wired counterparts, as it was mentioned before. But those devices have some advantages. Current generation projectors are smaller in terms of size, still providing the same quality. And those devices can be installed and operated on a table, floor, hung from the ceiling and in other places without messing with wires, of course. In addition, built-in proprietary software will allow you to remove any screen distortions, even if it’s installed at an angle to the screen.
So, speaking of the projectors itself, there are not too many variants too. The most popular devices are basic projectors with wireless capabilities or WiFi-enabled projectors. Those models are widely used in business and education, as those are allowing you to connect a computer or mobile devices, working on the same principle as shared network printers. Such projectors are easy to use, yet have some restrictions in terms of connecting devices to them.
Less common models are utilizing various wireless connection standards. Actually, there are two of them - WiDi/Miracast and WirelessHD.
• WiDi (Intel Wireless Display) and Miracast are image processing standards that were designed specifically to duplicate the screen of a laptop or smartphone using a wireless projector. One of its main features is the encoding and image transmission standards support, providing high compatibility between various devices.
• WirelessHD or “Wireless HDMI” is not a technology, actually, because it’s a wireless replacement for the HDMI cable that’s utilizing a pair of wireless transmitters. Those are not too popular and somewhat even outdated due to the growing popularity of other standards.
Of course, nowadays there are also some projectors utilizing a Wi-Fi Direct technology, thus working independent from any other devices. In general, such projectors are self-containing devices by all means, and you’ll need to send a source image or video directly onto it via direct Wi-Fi connection. It’ll allow you to use those devices combined with almost anything that has Wi-Fi Direct support without the need in some specific software. And almost all modern smartphones, tablets and even laptops already have such a function.
