Note

The specifications advertised are the minimum requirements required to run our application. It is always recommended to have performance/storage headroom on your devices to support other essential processes and applications essential to your workflow.

We don’t recommend a specific CPU chip type, but we do recommend buying the latest devices if you’re starting out with your deployments.

The minimum supported chipset will usually be governed by the operating system requirements. However, we will always recommend starting with stronger chipsets for better performance and longevity.

Understanding network specifications

The following table captures the network requirements for our three key endpoints. All bandwidths are denoted in bps (Bits per second. 500k means 500 kbps or 500 kilobits per second. Please not that this is in bits and not bytes).

Video calls

Call type Desktop WebRTC Mobile
  Uplink Downlink Uplink Downlink Uplink Downlink
One-to-one call with content share 500k 500k 500k 500k 500k 500k
4-party call with content share 1M 1M 500k 500k 1M 1M
16 or more participants with content share 2M 2M 1M 1M 1.5M 1.5M

How we evaluate network specifications

  • All test devices had a fresh install of the operating system (factory reset) and had a fresh installation of the relevant application (desktop and mobile).
  • No other audio/video conferencing apps were running on the device when they were benchmarked.
  • The benchmarking tests were performed in a controlled lab environment with bandwidth constraint. Bandwidth constraint was applied using Network Link Conditioner on MAC, iOS and Net Limiter on Windows.

What these specifications mean for you

  • It is important to understand the dynamic nature of network variations, and how they impact your device use and not just the use of audio/video conferencing software.
  • The specifications advertised above will serve as a guide for network capacity management. However, network capacity depends on a multitude of other factors, most of which fall outside of this document and the products it covers.
  • As with all specifications, it is always advisable to design with some headroom. A device may be under other forms of network load such as a software update, app updates, device backups or general background activities.
  • It is also advisable to design with some headroom owing to network fluctuations such as device crowding, network quality deterioration, general radio interference or issues at the ISP level.
