Bidding Farewell to the "Metal Shielding Effect": MN54L's Penetration Power Ensures IIoT Device Connection Stability in Containers and Cabinets
By installing the Device Under Test (DUT) inside the furthest end of a large metal shipping container and conducting connection tests within a parallel-container setting, we simulated severe conditions common in Industrial IoT (IIoT) applications where signals must penetrate metal structures, such as equipment cabinets, walls, or buildings.
Next-Generation Wireless Performance: RF Validation and Deep Analysis of Long-Range Bidirectional Bluetooth Communication on the Arad MN54L Module (Powered by Nordic nRF54L IC)
The design goal for this MN54L test is to directly inherit the high-standard validation methodology established by the MN52H testing. This ensures the data accurately reflects the most robust performance achievable by the MN54L module in complex and demanding applications, such as Bluetooth Mesh, Thread, and Matter. For consistency with previous tests, we utilize the MN52H-U40 as the MASTER/CENTRAL device, communicating bidirectionally with various antenna configurations of the MN54L modules. Testing was conducted in an open environment, specifically a beach location, to minimize interference from geographical obstacles and surrounding radio signals, thereby providing the most accurate and valuable reference data on the module’s ultimate wireless transmission performance.
Arad MN52H 250K mold Bluetooth Module Bi-directional Communication (MASTER/CENTRAL TO SLAVE/PERIPHERAL) Transmission Range Test
This report presents the latest findings from the Arad Connectivity MN52H BLE (Bluetooth Low Energy) module's transmission range test series. Following the successful verification of the maximum communication distances for the 125K (Long Range) and 1M modes in previous phases, the current testing focuses specifically on validating the bidirectional transmission performance of the 250K PHY mode in an open-field environment.
