The TeraLink iOS application allows users to link their cellular devices to Teradek Cube 600 series and VidiU Pro units. ShareLink brings professional bonding technology to the Cube 600 series. When enabled, it allows you to combine bandwidth from multiple network interfaces to increase your uplink speed for more reliable and higher quality streaming.
