Important Note Re WMM and Audio on some Smart phones
Please Note : Some Android Smartphone’s require WMM (WiFi Multimedia ) to be enabled in the
Wireless AP or Wireless routers for them to provide 2 way Audio back to the eGateway.
WMM maintains the priority of audio, video and voice applications in a Wi-Fi network so that other
applications and traffic are less likely to slow them. In this way, in a phone conversation, you are less
likely to hear delays. Watching video, you are more likely to see smooth action. This delays other
network traffic of a less critical nature — such as downloading large files — where a small delay is
acceptable.
In the Ness Smartbell a typical symptom of when this needs to be enabled is where on an android
phone you can hear the person on your Smartphone; however they cannot hear you when you talk
either at the Outdoor Phone (ODP) or on other Smartphones. If you encounter this then please
enable WMM on your wireless AP or Wireless router the Smartphone is connected to. The location of
this option will vary from wireless router to router; however as a general rule it can be found
somewhere under the QoS (Quality of Service) options and as a general rule is not enabled as
default.
e.g. Cisco Router.
If your router does not support this feature you will need to either replace the router with one that
does, or add a wireless AP onto the LAN that does support this feature and then have the
Smartphone connect to it via Wifi.
