To help ensure a seamless meeting experience, network administrators should follow the best practices in this article, when configuring a WiFi connection.
During calls and meetings on Webex Boards, Desk and Room Series devices, you'll quickly find out that a stable internet connection greatly enhances your video and voice experience.
We recommend that you use a wired network connection when available, for greater stability. In a home environment, consider using a powerline ethernet adapter to establish a dedicated and more reliable connection. However, if a wired connection is not practical, you can use a Wireless connection instead.
Important: when setting up a WiFi network, install wireless equipment - such as access points and routers - that can handle and distribute the load across connected devices. You'll probably connect a lot of devices to a wireless network, and bandwidth is limited.
The best practices in this article aim to improve two key metrics, thus improving the video and voice quality experienced on devices connected to a WiFi network:
-
Packet Loss Rate - the percent of packets that are lost during transmission, and,
-
Interarrival Jitter - the variation in arrival times of packets being received, in milliseconds.
To help ensure a seamless meeting experience, network administrators should follow these best practices when configuring a WiFi connection:
-
Avoid deploying access points from different manufacturers , as this can contribute to congesting the radio-spectrum.
-
Prioritize 5 GHz coverage for devices. If 5 GHz and 2.4 GHz share the same network name (SSID), then enable band steering to ensure that 5 GHz is prioritized.
-
Wireless channel utilization should be under 50%.
-
Enable 802.11d to add a country information element to beacons, probe requests, and probe responses. If your wireless equipment does not support this, then use world safe channels 36, 40, 44, or 48.
-
Verify that the device sees an access point at -60 dBm or better (closer to zero is better).
-
Verify that an access point sees the device at -60 dBm or better (closer to zero is better).
-
The 'Signal to Noise ratio' should always be 25 dB or more.
-
Enable 'Airtime fairness' , to make sure co-existing clients have equal access to airtime.
-
Enable QoS if available . Devices tag AF41 for video and EF for voice.
 | Home office setups using equipment from an Internet Service Provider might not support all the configurations in the list above. |
