1.3.2 Bandwidth Requirements

Mirroring (from Laptop or Phone to Large Display)

Maximum bitrate can be as high as 30Mbps, but average bitrates will be significantly lower. To get a

reliable user experience, it is recommended to connect the large display using Ethernet and the

laptop/phone using 5GHz Wi-Fi band.

TV Mirror and Display Group

The average bitrates of each TV Mirror or Display Group connection are 4 Mbps, the bandwidth should

be reserved accordingly. For example, in case there are 40 Pads or Laptops in the classroom using TV

Mirror, it requires 40 * 4Mbps = 160Mbps local traffic bandwidth.

WebCast

The average bitrates of each WebCast connection are 4~5 Mbps. It’s recommended to reserve a steady

5Mbps bandwidth for each WebCast Mirroring.
