18-meter Channel Sounding test with Nordic nRF54L15 SoC

Share：

[TAIWAN, 21th Jan. 2025]

Arad Connectivity recently completed an 18-meter Channel Sounding test using the two Nordic nRF54L15 evaluation boards. This test demonstrated the exceptional performance of the nRF54L15 SoC and provided valuable data for future wireless communication applications.

Channel Sounding is a technique used to evaluate the characteristics of a wireless channel, providing detailed data on signal transmission quality, interference, and channel response. This information is crucial for optimizing the performance of wireless communication systems. In this test, Arad Connectivity used the nRF54L15 evaluation board to conduct precise Channel Sounding over 18 meters, obtaining high-quality data.

The specific steps involved in this Channel Sounding test are as follows:

Preparation:

Equipment Setup: Ensure all testing equipment, including the Nordic nRF54L15 evaluation board, antennas, power supplies, and testing software, are ready.

- Framework version: NCS V.2.9.0/zephyr/channel sounding
- Initiator: Nordic nRF54L15 evaluation board
- Reflector: Nordic nRF54L15 evaluation board

Environment Setup: Choose a suitable testing environment, ensuring minimal interference sources, and measure the testing distance (18 meters in this case).

Configuration:

Board Configuration: Flashed the SDK NCS V.2.9.0/zephyr with error-free to configure the nRF54L15 evaluation board.

Channel Configuration: Set up the testing channel, ensuring the transmitting and receiving devices operate on the same frequency and channel.

Testing:

Leverages Bluetooth Channel Sounding Phase-based Ranging (PBR) and Round-Trip Time (RTT) to establish communication between the Initiator and the Reflector. The measured distance data is read by the LightBlue application.

Data Analysis:

Data Collection: Import the received signal data into analysis software for initial processing and organization.
