auXala - Network Requirements
(formerly known as CAST)
auXala supports WiFi and wired networks. To make your network "auXala ready” and provide the best possible experience, please ensure the following:
We recommend to use a separated, dedicated and professional network - it will drastically improve the stability and performance. We can recommend following brands of professional gear: Ruckus, Cisco, Ubiquiti and similar vendors, even though you can run auXala with any network that fulfils the requirements.
Transmitter and receiver must be within the same (virtual) network / IP range and be able to communicate on UDP/IP level. It's essential that the used IP addresses are able to connect to each other.
Unless your WiFi network can be configured in such a way, that devices are ensured to use a single band (2.4GHz or 5GHz) all the time, we recommend to use only 1 frequency band: either 802.11n (2.4GHz) or 802.11ac (5GHz). This is essential, especially if you run both frequency bands using the same SSID and devices start to roam between the two, connection problems and interruptions will occur.
NOTE: some Android devices do not support 802.11ac.
Client Isolation, also often called Access Point Isolation, prevents clients from directly communicating with each other via WiFi.
If the transmitter is connected via Ethernet cable, the Client Isolation setting will become irrelevant and can be either ON or OFF. If the transmitter is connected via WiFi, Client Isolation must be turned OFF.
auXala receivers are using the multicast feature to detect auXala transmitters within the network. We use group 18.104.22.168 on port 5055 to do so. To run auXala successfully, Multicasting must be turned ON and configured correctly. When clients are within different subnets multicast forwarding must be configured on a network level.
We recommend to set the DHCP lease time to as long as possible, at least to the amount of hours auXala will be used. Changing the IP address during the streaming process will result in unexpected behaviour.
We recommend the usage of Quality of Service within the entire network. It should be optimized for VoIP in mind. We recommend DSCP value of EF (46 or 101110 in binary) and CoS value of VO (5). Please refer to this Cisco guides about QoS and VoIP for more information.
Multiple WiFi networks in the same venue and running on the same channel might transmit at the same time and their radio signals will collide and become garbled resulting in data corruption or complete frame loss. If there is an excessive amount of collisions, data would never be transmitted successfully and the wireless network would be unusable.
To prevent such interference, we recommend to choose a channel for your WiFi network that is used by no/as few as possible other networks in range. Please refer to this Cisco Guide about Channel Planning for more information.
