Abstract

Ruijie commissioned Tolly to evaluate the performance and functionality of Ruijie’s next-generation hospital-wide zero-roaming solution built around the Zero-Roaming AP Divide RG-APD4930. The main focus of the project was to validate signal coverage, roaming continuity, bandwidth performance, network isolation, high-reliability backup, deployment flexibility, and visualized operations and maintenance for hospital wireless environments.  

The report describes the solution as a hospital-oriented architecture designed for mobile ward rounds, electronic medical records, mobile imaging, and other medical applications that require stable connectivity and high reliability. The RG-APD4930 uses in-room antenna deployment through ultra-flexible feeder cables rather than relying on corridor-mounted APs, and one AP divide can connect up to eight aesthetic antennas to extend coverage into patient rooms and adjacent areas. Tolly says this design supports hospital-wide signal reach while also enabling flexible long-distance and cross-floor deployment through hybrid optical-electrical cabling or Ethernet-based methods.  

A key technical theme is the combination of performance and mobility. In a hospital-like test environment with eight antenna locations, Wi-Fi signal strength remained stronger than -65dBm throughout the covered rooms. For mobility validation, two RG-APD4930 units deployed a co-channel Wi-Fi network and a mobile phone roamed between them six times while sending 1,400-byte pings every 0.2 seconds; Tolly reported zero packet loss during the full roaming test. Performance testing of the external-network Wi-Fi 7 AP showed 1.746Gbps single-user TCP downlink throughput on the 5.2GHz radio. In multi-user testing spanning the external 5.2GHz Wi-Fi 7 radio, external 2.4GHz Wi-Fi 7 radio, and internal 5.8GHz Wi-Fi 6 radio, the platform delivered 2.2Gbps aggregate TCP downlink and 2.46Gbps aggregate TCP uplink throughput.  

The report also emphasizes operational and architectural features. The RG-APD4930 uses separate CPUs and RF modules for intranet, internet, and IoT traffic, and Tolly verified that these three networks remained isolated even when endpoints used IP addresses in the same subnet. Ruijie’s controller also supported mutual backup between the internal and external AP functions, allowing one side to temporarily broadcast the other side’s SSID if an AP failed. On the O&M side, administrators could remotely visualize feeder and antenna status, view endpoint roaming paths and statistics, and trigger a buzzer on a specific APD for physical location. The platform also supports shared antennas across 2.4GHz, 5.2GHz, and 5.8GHz, one-second QMA quick-lock feeder connections, and multiple deployment options including PoE+, all-optical hybrid cable, and WDM-based networking. Overall, the report presents Ruijie’s hospital-wide zero-roaming solution as a purpose-built wireless architecture for smart hospitals, combining seamless mobility, strong throughput, traffic isolation, and maintenance-friendly deployment.
