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, CCS-UC-1, AM-3200, AM-3200-WF, and
AM-3200-WF-I have two LAN ports. The administrator can specify which port is used for
AirMedia in the device’s AirMedia configuration screen shown in
All policies, encryption, and other implemented security measures are applied to AirMedia
because 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, such as switches or routers, also apply to AirMedia. AirMedia
is a standard network appliance and is as secure as the supporting network.
AirMedia employs a proprietary protocol to transport the screen data to the device. In Windows,
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 , AirMedia 2.0 devices, and AirMedia
Series 3 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 and AirMedia Series 3 proprietary protocol. These numbers depend largely on
the type and complexity of content displayed.
Crestron recommends upgrading all AirMedia devices to the latest firmware to ensure optimal
network performance.
