    • Speed test

      UK users can use the Ofcom checker to Run a speed test and then click 'details' to see estimated upload and download speed.

      If you have an upload speed of ~500 Kbps (0.5 Mbps) or less, you may want to use voice only, especially if joining a group call (that is, turning off your video).

      ADSL

      Standard broadband (ADSL) normally has a maximum upload speed of around 1 Mbps and would be better suited to either one to one video calls, or audio only in a group call.

      Fibre

      Fibre services provide greater bandwidth so can handle more traffic and is better suited to group video calls, upload speed is improved.

  • Computer setup

    • Use a wired connection if possible.

      To free up processor resources for videoconferencing, try to reduce the number of programs and browser tabs you have open.

      Windows Laptop users can boost processor power available, however this could result in increased fan noise which may be picked up by the microphone - [Optimise the power mode]

    • WiFi

      Ask people using the WiFi to avoid any bandwidth intensive services (streaming, online gaming).

      For optimum performance try to have line-of-sight with your router.

      Consider actively switch WiFi off on other devices (even when not is use a router will try to maintain an active connection with multiple devices). If there are fewer to connect to then the router can offer a stronger connection to just yours.

      Avoid using a microwave.

    • Microphone

      Windows

      Start Menu > type 'Sounds' > Click 'Sound Settings' > Under 'Input' you can click 'Device Properties' and adjust microphone volume.

      MacOS

      Select Apple > System Preferences… > Sound > Input, where settings can be adjusted.

    • Browser

      It is preferable if you can install Webex meeting centre or Zoom when prompted.

      If you are unable to install and want to join a meeting via a web browser we would recommend using a Chromium-based browser (Chrome, Edge, Brave).

  • Lighting

    • Try to avoid having a light source / daylit window directly behind you.

      Do however make sure there are some lights on in the room. Webcams often perform poorly in low light.

      Test your setup

      Windows

      Open the Camera ‘app’ (Start Menu > type 'Camera') to get a preview of how everything looks.

      MacOS

      Open an app that can use the camera, such as Photo Booth, FaceTime, or Messages. A green light beside the camera glows to indicate that the camera is on and you can preview how everything looks.
