Wireless Audio Module SA326 Communication Range Test

SA326 is a wireless audio module launched by NiceRF and here is a test report about its communication range.

Test tools:

1 pair of wireless audio modules SA326-TX and SA326-RX equipped with row pins;

2 pcs of 3.3V batteries;

2 pcs of rod antennas in 868MHz band;

1 pc of mobile phone, 1 pc of audio cable, 1 pc of headphone cable

（SA326-TX）

（SA326-RX）

Testing weather: sunny 25 ℃

Testing location: Xinghua 1st Road(near NiceRF office building)

Testing distance: 200m

Set wireless audio modules SA326-TX and SA326-RX 200m apart. Open the mobile music software connected to SA326-TX and click play music. Observe whether the connection indicators (red and blue lights in the figure) of SA326-TX and SA326-RX are on, and listen to whether the headset connected to SA326-RX can hear music. (Note: during the test, the two rod antennas shall be vertically upward.)

200m test: communication status of SA326-TX and SA326-RX

It can be seen from the above figure that the connection indicators of the wireless audio modules SA326-TX and SA326-RX are on, indicating that the wireless audio modules SA326-TX and SA326-RX are connected and can receive and transmit audio data.

At last, confirm that music can be heard normally in the headset, indicating that the test on communication distance is successful.

That’s all about the test of Communication Range for wireless audio modules SA326.
