How Do Wireless Projectors Work?

Using a wireless projector makes communication between the presenter and the audience a lot better. 

Instead of having a lot of barriers between them, the presenter can walk around the room and have a stronger interaction with the audience. 

If you use a wireless projector, you will still have control over the visual part of the presentation. 

This can also be done through communication with the presentation device through wireless display chips or USB dongles. 

However, these are not true wireless projectors because they connect to a receiver through wired cables.

Basics of Using A Wireless Projector

A Wireless projector connects to computers or laptops through a Wi-Fi card that is built into the device. This card allows the projector to connect to other wireless networks on the device you are using. 

You will need to install a specific application that is provided by the manufacturer of the projector so that you can use this projector. 

This application will allow the projector to receive the data from the computer and will coordinate both encryption and compression of these data. Unlike what’s mentioned above, a wireless projector is not connected to the receiver using any cords.

Wireless Projector Connections

1. Ad Hoc /Peer-to-Peer Connection

One of the most used ways to connect your PC with the projector is using an ad hoc connection. 

Nowadays, it is considered the safest method for connection because there is a direct link between the two devices used that no other network shares. 

However, you can only use this type of connection if the two devices are within 150 feet from each other.

2. Wi-Fi Connection 

It is another method for a wireless connection. What happens is that you connect your projector and your PC to connect to the same Wi-Fi network. 

This can be done through a wireless access point or a router. The utility or application that you use for the connection searches the Wi-Fi network for the devices to recognize it. 

It also allows you to choose the projector you want to use, and you can use it to create a link between your devices.

3. USB Adaptor

The most common way for connecting to a wireless projector is by using a USB adaptor. A lot of projectors have USB ports. Yet, you might need to buy one separately. 

Another thing to keep in mind is that each brand has its own approved USB wireless adaptor. This adaptor is brand-specific and will only work with its own brand projector. 

Also, you must install a specific app to be able to use the USB to navigate the files found within the adapter.

4. HDMI Wireless Kit

It’s a way to connect to the projector in situations in which the projector is away from the device the video you want to present is on. 

It is more convenient to use an HDMI wireless kit than using a very long HDMI cable to a projector that is 30 meters away.

The kit comes in two parts. One part represents a transmitter while the other represents an adaptor. 

The transmitter can be connected to a source like a DVD player, AV receiver video output, or Blu Ray Player. 

On the other hand, the receiver is connected to the projector.

One of the limiting factors when it comes to using an HDMI wireless kit is that it needs a straight line of sight to work without any flows.

5. HDML/MHL Adaptor

This is the newest type of wireless connection. Before getting an MHL adaptor, you need to make sure that your projector is compatible and has an HDMI/MHL port. 

One of the best features of this adaptor is that it can power the projector by itself without the need for any additional power.

However, you will need to download an app for the relevant adaptor to be able to establish a connection. 

You can use the MHL adaptor in a non-MHL port, but in this case, it won’t be able to power the projector since it is plugged to an HDMI port.

6. WIDI Wireless Connection

You can only use WIDI connection with particular laptops that have an Intel processing chip with WIDI built-in. 

It allows you to present different media on your projector, like videos and pictures, as well as documents wirelessly. 

You should check your laptop manual or contact the manufacturer to check if your laptop supports WIDI connections.

7. Chromecast Connection

Google Chromecast is one of the easiest and most reliable ways to watch videos on YouTube and Netflix.

First, you will need to install it in the HDMI port in your projector. Then you should download an app from either Apple or Android Store depending on the device you are using. 

After the setup, you will get a “cast” button on your application that you can use to play your video over the projector. 

Basically, your device will be in control of what’s showing on the projector, and you can select the video you would like to “cast” from your device, and it will be directly shown on your projector. 

The advantage of using Chromecast is that it will download the content you want to display and at the same time.

It frees up the resources found on your handheld device. This allows you to use the handheld device to do something else while the Chromecast is playing.

The only downside is that you won’t be able to display pictures or documents. We recommend you use a USB or HDML/MHL wireless adaptor in such cases.

Conclusion

Wireless projector connections are far more engaging than wired ones. They allow you to communicate more with the audience and provide a better presenting experience. 

There are a lot of ways to get a wireless connection between the device you use and your projector. This device can be a computer, a laptop or even your phone.

However, you will need to check if your projector supports specific ports and that you are capable of using certain methods to establish a wireless connection between your device and projector. 

You also might need to download an app on your device to make such connections.
