Global Impact

Employment

Keep remote workers productive and employed

Education

Keep students engaged and on-track with their peers

Equity

Reduce educational and employment inequities

Health

Ensure reliable access to tele-medicine

The deployment of LibreQoS helps small and mid-sized ISPs to compete against large incumbents through superior QoE, and ensures that their subscribers enjoy stable, dependable connectivity for work-from-home, remote learning, and tele-medicine. Here are some examples of how LibreQoS can have an impact:

  • A disabled woman using a wheelchair depends on reliable, low-latency connectivity from her ISP to facilitate tele-medicine calls with their healthcare provider. LibreQoS helps keep her connection latency stable – no matter the network load – to ensure her equal access to the medical care she needs.
  • A rancher in a remote village depends on  reliable upload connectivity to monitor his cattle trough webcams. His ISP uses LibreQoS, so even during hours of high congestion – his camera feeds remain crisp and stable, keeping his cattle safe, and protecting his livelihood.
Worldwide adoption of LibreQoS
