# WeldCloud IT requirements

Connectivity to WeldCloud apps is enabled through gateways establishing a secured and encrypted connections to InduSuite platform.
Few requirements should be met in your shopfloor network infrastructure to grant a smooth installation.
Furthermore advanced features may require a Bluetooth connection between gateway and WeldCloud Link app (please refer to this [article](/en/article//) for more details on WeldCloud Link)
