A projector is one of the most important tools utilized in countless situations every day; like meetings or lectures. There are many different types of projectors weather corded or wireless. We will discuss wireless projectors in order to understand how they work.
All wireless projectors contain a Wi-Fi card or chip that enables them to connect and communicate to either your laptop, tablet or computer.
The projector’s manufacturing company always provides you with a connection utility program or application, which must be set-up and installed before using the projector. Moreover, it handles all the data, whether through compressing, encrypting or finally sending it.
Ad Hoc Connection
This is the safest and fastest method that you can use to connect your wireless projector. This connection is also called a peer-to-peer connection. It creates a direct link between your projector and your other devices. This link, however, is exclusive to these two devices only as no other device can access it. Still, the two devices need to be within 150 feet of each other.
Another method to connect a wireless projector would be to connect it and your laptop or computer to the same Wi-Fi network. This is fairly straightforward to create as all you have to do is to connect your two devices to the same network using a router or a wireless access point. The projector’s utility application will automatically search for any device that it recognizes, select your projector, and the link will be created.
The only difference between the network connection and the ad hoc connections is that in the network, any information you send whether pictures or slides or anything else will travel through the router or wireless access point. This makes the ad hoc a much safer option.
As simple as it gets, most wireless projectors come with a USB port. However, each brand’s own approved USB adaptor will only work with its projector meaning that you have to match the USB adaptor’s brand with the projector’s brand. Also, you will need to download an application to navigate the files within the adaptor.
This is a relatively new type of adaptor that was released very recently. You need to have an MHL compatible projector to use the MHL adaptor. However, if your printer is not MHL compatible, you can plug the adaptor into the HDMI port, but you will require extra power. You can use the MHL adaptor by plugging it into its port without needing any extra power and then proceed to download the adaptor’s application, and you are good to go.
This is amazing for watching videos and movies using your projector. All you have to do is to install the Chromecast into your projector’s HDMI port. Then you have to download the Chromecast application on your smartphone (it supports both Apple and Android). And you will find that a cast button has been added into your apps, for example, Netflix or Youtube.
As simple as clicking a button, your projector will feature projector whatever is on your smartphone. Your smartphone will act as a remote control; you can use it to pause, play and decrease or increase the volume.
Miracast is an application that allows you to mirror the screen of your device to the projector wirelessly. This means that the projector will show whatever appears on your device. However, Miracast supports Android only, as any Apple device is not supported. You can also buy a separate Miracast adaptor to make any projector that has an HDMI port compatible with Miracast.
HDMI Wireless Kit
The HDMI kit consists of two parts: a transmitter and a receiver, you use the kit whenever you do not want to connect a long HDMI wire, and you need the space to move around. The transmitter must be connected to the source, for example, the DVD player or the Blu Ray player, while the receiver must be connected to the projector itself.
An important tip is to always clear the space between the transmitter and the receiver; there shouldn’t be any people or objects blocking the transmission between them. However, some of them can penetrate walls and go in between levels.
Wireless projectors are a significant step-up from wired ones; there are multiple methods of making them work either through USB adaptors, HDMI kits, Miracast, Chromecast or even an Ad Hoc connection. All of these methods are straightforward and require minimal effort and time to perform. Sharing your ideas, presentations, and even your movie library has never been easier.
