But not all WLAN projectors are the same: there are fundamental differences, ranging from smart all-in-one solutions for home cinema to devices that specialise in fast content mirroring in the office. The following overview explains the different types, how the technology works and what you should look out for when choosing a projector for your personal use.

The classic WLAN dongle:

One common method is to use a WLAN dongle. This is usually connected to the projector via USB and has the task of establishing a purely wireless connection. It is the right solution if you want to use specific functions such as screen mirroring (e.g. via Miracast).

Smart TV / streaming sticks:

In addition to the classic dongle, the use of a Smart TV or streaming stick is another very popular option. A stick such as the Google Chromecast with Google TV or Apple TV is connected via HDMI. This equips the projector with a complete operating system, apps and its own remote control, transforming it into a fully-fledged Smart projector.

Wireless HDMI systems:

For loss-free and low-latency transmission, a wireless HDMI system is the professional choice. It replaces the HDMI cable with a stable, direct wireless connection and is therefore ideal for sophisticated home cinema.
