• Capabilities of the radios that the most commonly-used connecting devices will
have, and take advantage of both 2.4 GHz and 5 GHz bands and newer
technologies such as 802.11ac whenever possible. 5 GHz bands have far more
channels and capacity than 2.4 GHz, though not all devices support both bands.
Additionally, 5 GHz devices can have more limited range through walls and
objects than 2.4 GHz devices.
• Minimize the use of unmanaged and unwanted wireless devices via corporate
policies and control of Wi-Fi network device access.
• Conduct a wireless survey with calibrated equipment to understand coverage
overlaps and holes, appropriate access point power levels, and channel
bandwidths.
Most wireless equipment vendors have authorized providers of design and survey
services which should be used whenever possible.
Proper network architecture between the sender and AirMedia device is key. Some
considerations include:
• Minimize the number of network hops from the wireless access point to the
AirMedia device.
• Use high-quality, non-blocking switches and routers with sufficient capability to
move unicast streaming traffic from senders to AirMedia devices.
• Avoid scheduling processor intensive or network-intensive applications in the
background, such as backup and software upgrades, at the same time the
AirMedia sender is active.
Minimizing traffic from non-AirMedia devices can be challenging given end user
expectations on wireless networks. There are several techniques to help ensure AirMedia
traffic is prioritized:
• Keep AirMedia devices and traffic on their own VLANs and subnet, but routable
from outside.
• Use quality-of-service features on switches and routers to prioritize AirMedia
traffic as per the audio/video ports listed elsewhere in this document.
• Conduct network traffic flow analysis to identify network hot spots around the
AirMedia device.
If Bonjour® or multicast DNS services are to be blocked, the blocking needs to occur at
the switch level. If blocking occurs on a macOS or iOS sending device due to
administrative policy regarding firewall settings, the native mirroring connection to
AirMedia presentation gateways will not be possible without the AirMedia app. Some
organizations manage mDNS and Bonjour on their network using specialized
management tools that minimize broadcast chatter while still providing services. These
tools can occasionally interfere with device discovery and should be configured to
prevent such interference.
