Airmedia Network Infrastructure And Security; Airmedia Bandwidth Requirements - Crestron AM-200 Deployment Manual

AirMedia Network Infrastructure and Security

AirMedia leverages existing IT network infrastructure and policies. It contains a single-
wired network interface with no wireless interfaces or bridges in the device. AirMedia
becomes a wireless solution by utilizing the existing wireless network in the deployed
network infrastructure.
NOTE: The DMPS3-4K-250-C, DMPS3-4K-350-C, and CCS-UC-1 have two LAN ports.
The administrator can specify which port is used for AirMedia in the device's AirMedia
configuration screen shown on page 11.
All policies, encryption, and other implemented security measures are applied to
AirMedia as AirMedia data is identical to standard Ethernet traffic. AirMedia traffic on
the corporate network is treated like any other streaming network traffic. All existing
policies that apply to physical network devices (switches, routers, etc.) also apply to
AirMedia. AirMedia is a standard network appliance (like a printer) and is as secure as
the supporting network.
AirMedia employs a proprietary protocol to transport the screen data to the device.
Average bandwidth requirements are typically low (down to 1.4 Mbit/s on AirMedia 2.0
devices such as AM-200, AM-300, DMPS3-4K-250-C, DMPS3-4K-350-C, and CCS-UC-1).
Bandwidth varies depending on content, but will not drop below 0.25 Mbit/s or exceed
8.5 Mbit/s. In Windows only, the quality slider in the setting limits the peak bandwidth
only, not the average or minimum bandwidth, and behaves logarithmically rather than
linearly.
When using native mirroring in macOS and iOS with AM-101 and AirMedia 2.0 devices,
the OS negotiates and controls the bandwidth to the AirMedia device due to the way the
native mirroring protocol is defined. Official numbers are not published for minimum and
maximum required bandwidth, but observed minimum and maximum numbers are
similar to the AirMedia 2.0 proprietary protocol. Typical average bandwidth has been
measured at approximately 5Mbit/s. However, these numbers depend largely on the
type and complexity of content displayed.
It is highly recommended to upgrade all AirMedia devices to the latest firmware to
ensure optimal network performance. AM-100 and AM-101 devices with the latest
firmware have average bandwidth usage of 1.5Mbit/s or greater, while AM-100 devices
with older firmware may have much higher bandwidth requirements on the order of over
32Mbit/s average and 46Mbit/s peak when displaying full-motion video.
The following table summarizes the bandwidth requirements for AirMedia devices.
