A few decades ago there's little doubt that a wireless video projector had never been envisioned. Now that wireless projectors are here, there can be little doubt that this is the standard that all future portable projectors will need to live up to.Wireless projectors work using 802.11 technology. IEEE 802.11 is a set of standards for wireless local area network (WLAN) communication, usually referred to as just 802.11, or perhaps more commonly known as "Wi-Fi". Some other common Wi-Fi enabled devices include PCs, game consoles, cell phones, MP3 players and PDAs.
In the case of wireless projectors however, they are most commonly used in conjunction with a laptop, used to control and send the media the projector is to display. The obvious benefit of this duo is the portability and the ease of setup. The combined weight of a laptop and an Ultraportable Wireless Projector is less than 20 pounds, so it's as easy as carrying them in the door, setting them down, and turning on your laptop to begin with a presentation. The future is here, and it works without wires.
