Bandwidth is the capacity of a network connection to transfer data, typically measured in Mbps (megabits per second). In digital signage, bandwidth determines how fast new content can be distributed to players, how reliably real-time data feeds reach displays, and whether high-resolution video can stream without buffering.

Properly planned bandwidth is essential for stable digital signage operations. Cloud-based platforms like Livesignage optimize bandwidth through intelligent caching: players download content once and play locally, so live network demand is limited to content updates, telemetry and data feeds — not continuous streaming.
