Switches, Access Points And Qos; Network Bandwidth - Sennheiser MobileConnect User Documentation

Switches, Access Points and QoS

1. Use Quality Equipment
We strongly recommend to use enterprise-grade switches and WiFi equip-
ment and keep a close eye on the delivery of our data especially when the
installation needs to support a large amount of simultaneous listeners.
2. "Just like VoIP"
Our audio streaming traffic is similar in structure to VoIP traffic, so lots of
lessons learned there will apply here, too. The main difference is that our
traffic is mostly unidirectional, i.e., there is not much data traffic origina-
ting from the client devices. Keep this in mind when configuring WMM and
QoS settings in your network and WiFi controllers.
3. Requirements for Switches
Any cabled infrastructure should be Gigabit Ethernet or better.
All involved switches should:
• support QoS with strict priorities,
• not queue up any of our traffic (especially the audio payload on ports
32xx) and
• have energy saving functionality disabled.

Network bandwidth

The bandwidth usage is similar as for Voice over IP.
The system creates a bandwidth of 90 - 200 kbit/s per client. Please be
aware that in WiFi, the actual throughput can diverge significantly from the
basic rate.
