The modern smartphone you have in your pocket or purse has more power than a 1980’s mainframe computer, and a 4K television has over 8.3 million pixels for you to share your presentations or photos right from that phone. Many of us have more smart devices in our homes than ever before, but we don’t know how to easily share content among them. If you are working from home or have huddle rooms in your facility, you should to take a closer look at how to connect phones wirelessly to your TV quickly and easily.

There are three ways you can wirelessly connect your phone to TV :

The Solution

Using a proprietary network app on your phone

The A proprietary app that runs on your phone to stream content over your wireless network. This was one of the early ways that businesses started using with phones to wirelessly connect to a TV, and the method remains especially popular for interactive displays in classrooms.  For huddle spaces and home offices, this approach has drawbacks. 

First, the receivers use up your network bandwidth to stream video, which can slow speeds down for everyone else. Also, most of these systems have specific network configuration requirements regarding which ports to open or how much bandwidth you have to have, and may require special features such as multicast to be configured. More importantly, if you have a visitor who wants to share content from their device, they will have to download the app and then gain access to your network. This is a security risk IT managers try to avoid, as once a hacker gains access to your network, a lot of damage can be done in a short time. Some of these systems have also shown security flaws that allow hackers to use the receiver to break into your network and potentially shut it down.

Using AirPlay or Miracast to mirror your screen

If you are looking to only do wireless screen mirroring of content occasionally, and have a Google Chromecast or Apple TV setup to stream content, either of these devices can be used to connect to your phone. These systems use either Miracast or AirPlay features that are already on your phone. They are best if you occasionally share photos as compared to PowerPoint or video files, where your audience will be more sensitive to delays and lower quality.
