Focusing on in roaming packet loss and network construction separation in the healthcare industry, Huawei innovatively develops an innovative zero-roaming distributed Wi-Fi solution. In this solution, one distributed AP (DAP) connects to eight optical radio units (ORUs) and 64 antenna units (AUs). Working with next-generation hybrid cables, the solution implements 500 m ultra-long-distance deployment and provides Wi-Fi coverage for 64 rooms, building Wi-Fi networks with zero roaming and zero service interruptions. Based on industry trends and user requirements, Huawei's zero-roaming distributed Wi-Fi solution builds a future-oriented next-generation Wi-Fi network for the healthcare industries. This solution helps the industry build an intelligent network featuring zero roaming, wide coverage, and three-network isolation & converged deployment, greatly improving work efficiency in healthcare.
