Webex Desk Hub is designed to meet the needs of the modern work place. Use the information in this article to get the best possible experience from your device.

Keep these practices in mind as you set up and use your Webex Desk Hub:

  • Webex Desk Hub requires the Webex Desk Camera and a display screen to get the full supported benefits of the device. The Cisco Headset 730 and the headset charging stand are the recommended headset and headset charger for your device.

    Webex Desk Hub doesn't support display screens with a display aspect ratio greater than 16:9.

    The Apple Thunderbolt Display is not supported.

    Don't use a USB hub or similar device to power the Desk Hub or accessories.

  • Webex Desk Hub comes with a USB-C to USB-C cable to connect to your computer, and a USB-C to HDMI cable to connect to an HDMI display screen. Do not replace these cables with third-party substitutes.

    Each USB-C cable has a colored mark on it that indicates it's purpose. Blue is connecting to your laptop. Red is for connecting to an external display screen.

  • Webex Desk Hub has an acoustic horn that enables ultrasound proximity pairing. This feature functions best when it is the only ultrasound pairing device in the room.

    Some laptops have automatic noise canceling turned on by default for the microphone input. This prevents ultrasonic pairing.

  • If your device gets dirty, wipe it with a soft, dry cloth. Don't use any liquids or powders on the device because they can contaminate the components and damage the device.

    Don't expose the Desk Hub to water or liquids as they could damage it. It's water resistant, but it isn't waterproof.

  • Don't let the power adapter hang free because the stress damages the unit.

  • Some Webex Desk Hub features require Consumer Electronics Control (CEC). If you use ans HDMI display, then connect your device to an HDMI-CEC port on the display screen. Refer to the screen documentation for additional information.

  • Your Desk Hub has a wireless charging pad so you can charge your mobile device. Check your manufacturers guidelines about keeping your phone on the charger for extended periods of time.

A stable internet connection is the foundation of great video and voice communication. While a wired connection is the preferred method for a stable connection, Wi-Fi is acceptable when you don't want cables, such as in home offices.


When setting up a Wi-Fi network, confirm that your equipment meets your needs and that it is up to date. Signal congestion, hardware limitations, and outdated firmware affect network performance. In a home environment, consider a powerline Ethernet adapter so you have a dedicated connection.

The two key metrics for a wireless network are as follows:

  • A Packet Loss Rate of 1 percent or less.

  • Interarrival Jitter of 100 milliseconds(ms) or less.

Here are a few more guidelines for stable voice and video over Wi-Fi. Some home office equipment may not support all of these configurations:

  • Prioritize 5-GHz coverage for devices. If 5-GHz and 2.4-GHz share the same network name (SSID), then enable band steering so that 5-GHz is prioritized. Ideally enable the SSID on 5-GHz only.

  • Wireless channel utilization should be under 40 percent.

  • Enable 802.11d to add a country information element to beacons, probe requests, and probe responses.

  • Verify that the device sees an access point at -67 dBm or better. The closer this metric is to zero, then the better your network performance.

  • Verify that the Rx sensitivity level per channel and data rate is reached on the access point.

  • The Signal to Noise ratio should be 25 dB or more.

  • Enable QoS if available.
