Do not use a mesh network. A mesh network is
comprised of multiple nodes that communicate
with each other to provide wireless access to a
single network. These nodes may also be called
points or extenders. You may also think of these
nodes as being wirelessly daisy-chained to one
another. Mesh networks have a high likelihood of
causing excessive latency, dropouts, and
unwanted noise because it extends the pathway
from the user device to the Listen EVERYWHERE
server. Refer to Figure 2 on the right.
•
Use an open network (no encryption). Using
encryption can lower the number of users that
can connect to the WAP and add latency to the
LE system. TKIP encryption should not be used.
•
Enable Quality of Service (QoS) for the LE server
on the network. By default, the LE server uses
the 0xB8 Type of Service/Differentiated Services
(ToS/DS) tag so that audio data can be prioritized over other data traffic on the network.
This priority allows the latency and dropouts to be as low and infrequent as possible
while travelling over the network. The QoS setting may still need to be enabled on the
managed network, especially if there are many other connected devices or there are
existing QoS prioritizations on other connected devices.
•
Ensure that there is adequate Wi-Fi coverage. If latency improves as a user moves
closer to the wireless access point or when there are less users connected to the
network, the venue may need to consider adding additional wireless access points for
adequate coverage and bandwidth allocation. Network speeds can also be tested using
third-party apps. Refer to our
Wireless Access Point Optimization for Listen
•
Consider network frequency. Typically, users will receive better performance on the
5GHz frequency versus a 2.4GHz frequency. The 2.4GHz frequency can usually be
turned off through
your network’s admin interface.
However, 2.4GHz frequencies will
work more efficiently as the user moves further away from the access point. Both may
be considered depending on your wireless access point placement.
•
Check your mobile device. Some third-party, low-cost and/or older mobile devices may
not have high computing power or strong Wi-Fi antennas. Test with multiple mobile
devices to isolate the problem. If the problem exists on one or few devices, it may be
necessary to use an alternate mobile device to stream audio.
