During the recent COVID-19 crisis, many students are now equipped with a Chromebook so they can learn either at school or home. But what are the options for students and teachers who want to share or present from their Chromebooks in a classroom? The latest wireless presentation systems designed for classrooms have four advantages for teachers and students over traditional approaches.
While some classroom devices such as interactive displays have embedded anti-microbial coatings, passing a cable from one person to another creates the risk of spreading disease in a classroom. Each time a cable passes from one person to another – it should be disinfected. In the case of a interactive display there are two cables – a HDMI cable for the video, and a USB cable for the touch function.
The alternative is a classroom based wireless presentation system that connects to any Chromebook, and can transmit up to 40 feet away from the projector or display. Because a wireless presentation system supports multiple buttons, students don’t need to share a cable. They can even present from their phone or tablet using Miracast or Airplay.
With an interactive display, you can control your Chromebook directly from the display and avoid the hassle of using a USB cable. This is helpful as longer USB cables are expensive and hard to find. With a wireless presentation system, the display will synchronize both video – and USB touch data – between the display and the Chromebook. Now if the teacher moves to the back of the room during a lesson, they still have full interactive control.
Classroom wireless presentations systems can enable older projectors and interactive whiteboards to display more than one presenter at the same time. With a press of a button, a teacher can display up to four different sources, whether that be a microscope feed, Raspberry Pi STEM projects, media players, and of course Chromebooks. There is no software involved, and it is as easy as plugging in a button to the device you want to display.
Post COVID-19, the amount of traffic on a school network has grown exponentially. The best classroom wireless presentation systems keep the traffic off the school network using advanced WiFi frequency switching technology that enables the buttons to find open frequency channels to communicate with the display – and avoid burdening the school network. Other wireless systems that use the network can add up to 100 mb/second to your network – potentially slowing it down or reducing the response time.
Not much. The latest classroom wireless presentation system - the BenQ InstaShow WDC20E is priced at a single unit cost of $699, a fraction of what other wireless presentations cost with similar functionality. If you want to try one out in your classroom, apply for BenQ Try and Buy program and get a unit for 30 days to try out – and save $200 if you decide you want to keep it.
