Which is the best wireless HDMI technology for sharing high-resolution K-12 classroom displays - BenQ, Mersive, or Airtame?

Wireless HDMI Screen Mirroring Options for K-12 classrooms - which is the best?

2019/11/13

Which is the best wireless HDMI technology for sharing high-resolution K-12 classroom displays - BenQ, Mersive, or Airtame?

Legacy low-resolution projectors that were connected to a teacher's desk are being replaced by advanced high-resolution interactive projectors and flat panels. Modern flipped classrooms demand the alternative placement of displays; teachers are delivering on their promise of improved student performance, many IT administrators are looking at how they can incorporate wireless HDMI technology to enable students and teachers to mirror their screens in classrooms intuitively.

So what should IT managers look at when evaluating what screen mirroring system is right for their teachers and students?

BenQ InstaShow Wireless Presentation System for K12 Classrooms
Need #1 - Protect your campus network

Many wireless presentation systems rely on the school network to share data from students and teachers to the projector or interactive flat panel. There are two areas that IT managers have to manage – bandwidth and security.

Consider Network Bandwidth Impact

For wireless presentation systems such as Kramer and Airtame that rely on the network, many have specific bandwidth requirements for each presenter that is logged on – as well as the display. For example, the Kramer VIA can require up to 25mps per user when sharing video, and the Airtame2 unit also requires up to 13 Mbps with a one-second lag to display a video after a one-second delay. With dozens of students and teachers using these at the same time - this could overload your network infrastructure.

Solution – look for a wireless presentation system that doesn’t burden the classroom network.

Network Security

Keeping the campus network secure is critical – and wireless presentations that are highly dependent on network access need to be managed and updated to ensure that hackers don’t use the system to access or shut down the network.

Solution – look for a system that minimizes the need to use your campus network – and keeps it safe.

Need #2 - Connect to lots of different BYOD devices in classrooms and STEM labs

Electronic devices fill today's classrooms; even microscopes now have HDMI ports. Look for a wireless presentation system that enables a wide variety of different devices and media players to connect to the projector or flat panel wirelessly. The best wireless presentation systems can connect to Chromebooks, digital microsopes,and inexpensive STEM Beagle Boards.

Solution – look for a system that enables you to connect to any device in your classrooms that can output to an HDMI signal.

Need #3 - Something so simple - anyone can use it without training.

Many teachers need to spend time learning teaching tools that are critical to student success – not thumbing through a 100+ page user guide to figure out how to mirror their screen using a proprietary app. With new wireless collaboration systems such as the BenQ InstaShow, it is as easy as plug in, press the button, and present – enabling teachers and students to present in seconds without any additional training.

Solution – look for a system that enables teachers and students to use it without any dedicated training.

Other considerations

With many classrooms transitioning from traditional projectors to new 4K interactive panels, IT managers may want to look at “touch back” systems that enable teachers to annotate their lessons on the notebook by writing on the interactive flat panel. Some systems enable you to support multiple presenters on the same screen, as well.

What are the most popular systems - and how do they stack up?

According to Futuresource,over 30 companies are offering wireless presentation system today. So which popular systems offer the best solution for K-12 classrooms? Here is a comparison of a few of the popular systems being used today in K-12 classrooms.
