Audio Everywhere

INSTALLATION TIPS

• Mount the system where it can easily be reached to reboot.
• To access advanced features, the system must be connected to a public internet network ensuring wireless phones can see wired local servers.
• Access points need to be 801.11n or better; dual band preferred.
• If you want a static IP address, please request prior to shipment.
• Avoid mesh or multi-hop networks and avoid crowded wi-fi frequencies.
• Perform a site survey and check interference issues before finalizing the installation.
• 2.4 GHz Wi-Fi has only three non-overlapping channels.

I.T. CHECKLIST

• Train venue personnel on how to reset the system
• Train venue personnel on how to reset the router
• Access point (AP) is enterprise grade
• System has good ventilation
• Smart phone can hear audio with Audio Everywhere app
• Smart phone can access internet while app is running in background
• Access point bandwidth is set to 20 MHz on 2.4 GHz, 40 MHz on 5 GHz band
• Router/DHCP server IP address range is at least 200
• IP lease times are less than or equal to 24 hrs (1,440 min or 86,400 seconds)
• Mesh or multi-hop Wi-Fi WLANs are NOT used
• TKIP encryption is NOT used
• Signal-to-noise ratio on the Wi-Fi channel is at least 20 dB
• A dual-band single-radio AP is NOT used
• Check Wi-Fi spectrum with a tool like Android's Wi-Fi Analyzer app to make sure there are no channel conflicts

Recommended

• Access point is dual-band
• Access point is 802.11 ac or better
• Access point uses "airtime fairness" to favor advanced phones
• Access point uses "band-steering" to favor the 5 GHz band
• BSS minrate set to about 12,000
• Router/Switch is 1000 baseT (Gigabit) connected with correctly terminated CAT6
• Untwisted pair Ethernet wires should be no longer than 1 cm
• Wi-Fi encryption is NOT used, the system is OPEN
• After performing a site survey, the AP frequency is set to a fixed value, or mean time between channel hops is no less than 30 min

NETWORK GUIDE

LAN Ports and Services

• Servers expose an HTTP server on port 8000. They both receive and originate requests on this port. Protocol HTTP.
• Servers expose a file server on port 90. Protocol HTTP.
• Servers listen on port 16384.
• Servers use RTP on port 16384.
• Servers use Zeroconf (Bonjour/Avahi). Multicast UDP (also called mDNS), usually on port 5353 (Typical address 224.0.0.251).
• For enterprise mode operation (via IP address or CNAME), mDNS is not needed.
• The servers send RTP packets using UDP to the apps over a range of ports.
• Service IDs are _ExXothermic._tcp and _AsClientExXothermic._tcp.

WAN ports and services

• Our Cloud server is gears.exxothermic.com (IP address: 108.166.110.178, but subject to change) via Cloud port 1025. Protocol HTTP.
• Media files are stored on *.rackcdn.com Protocol HTTP.

How they look if you scan the LAN

• MX2's: ExXtractor v.2 (Shuttle)
• MX3's: Odroid (WIBRAIN)
• MX3 and MX5 after 2.47 shows Venue Server serial number. E.g., AEL4-43HY-...

The network diagram illustrates the system's connectivity. An "AE Server" is shown. It communicates using UDP on port 5353 (Zeroconf/mDNS) with a smartphone running the Audio Everywhere app. It also communicates via HTTP on ports 90 and 8000 for file serving and HTTP requests, respectively. Additionally, it uses RTP/UDP for audio streaming. The server connects to external services: the cloud server gears.exxothermic.com via HTTP on port 1025, and media files are accessed from *.rackcdn.com via HTTP.

Alerts

• For Cisco equipment, see audioeverywhere.com/Cisco.
• For Aruba equipment, see audioeverywhere.com/Aruba.
• When using guest mode, white list the Venue Servers based on the Venue Server MAC address. Guest modes typically have many security features varying based on vendor. See audioeverywhere.com/GuestNet.
• ASUS wireless routers are generally incompatible with the Audio Everywhere system, especially when isolated from the internet.
