Projectors with WLAN are becoming more and more popular. This is not least due to the fact that more and more WLAN projectors can connect directly to a smartphone or a tablet. However, Optional WLAN projectors are not the same integrated WLAN projectors. The biggest difference between the two types of WLAN projectors is how the wireless connection is implemented.
The integrated WLAN projector offers a fixed WLAN interface meaning no one can remove the WLAN dongle making the wireless connection unavailable. The second variant of a WLAN projector works with an optional WLAN interface, which is usually available as a USB WLAN dongle. This offers the potential to add WLAN to the projector in the future if required.
A third variant, also a WLAN option, are HDMI-based wireless adaptors. They are connected to the projector via the HDMI port and are powered via USB, or via MHL (Mobile High Definition Link). In addition to a conventional WLAN variant, they often offer additional functions such as Miracast or DLNA.
