(LE Coded1M Field Test) From the data, a truth emerges: The MN54L-C15 Chip Antenna's communication distance increases by 22% when oriented correctly! Arad MN54L (Nordic nRF54L15 module) Transmission Range Takes a Leap Forward
This article shares the results of our open-field communication range test for the MN54L BLE module. The objective was to verify the difference in effective communication distance when the module is rotated by 90 degrees compared to its original orientation. The test compared the transmission performance of different antenna types (Chip and PCB) in various orientations. We used an iPhone 7 as the receiving device and conducted the tests in an open and unobstructed outdoor environment to simulate real-world application scenarios.
A Generational Leap in Low-Power IoT: A Comprehensive Comparison of Nordic's nRF54L and nRF52 Series in Power and Performance
For a long time, Nordic Semiconductor's nRF52 series has been one of the most popular Bluetooth Low Energy (BLE) solutions on the market, known for its excellent balance. However, as application scenarios become increasingly complex, the demand for high performance and ultra-low power has grown. In response, Nordic has introduced the next-generation nRF54L series, heralding a generational leap in technology. This article will delve into a detailed comparison of the nRF54L and nRF52 series, analyzing the revolutionary advancements of the new chip from processing power and energy efficiency to overall design philosophy, and assessing how it is poised to redefine the design standards for future low-power IoT.
