UWB base station label testing process

Shenzhen Weineng Information Technology Co., Ltd. (95power), as a professional supplier of UWB base stations, UWB tags, and UWB positioning engine algorithms in China, is extremely strict in the testing of UWB positioning hardware products to ensure the quality of our shipmentsUWB positioningThe consistency between the quality stability and product performance of base stations and tags.

The production testing process for UWB base stations and tags is shown in the following figure:

Step 1: Routine functional testing of UWB base station tags

95power product testing engineers will conduct detailed testing on every function of every UWB base station and tag that leaves the factory.

Step 2: RF performance testing of UWB tags and base stations

The RF performance testing of UWB base station tags is the most complex and critical part of the entire product testing process, including power and frequency calibration, antenna delay calibration, and receiver sensitivity testing.

1. Power and frequency calibration. The power and frequency of UWB base stations must be within the specified range to ensure consistency in product transmission performance.

2. Antenna delay calibration. The unique delay parameter between the antenna of each UWB base station and the product (1ns results in a 30cm error).

3. Sensitivity testing for reception. The receiving sensitivity of each base station tag must be greater than a certain value to ensure the consistency of product receiving performance.

Step 3: Product Aging Stability Test

All 95power UWB base station label products undergo aging testing and high and low temperature sampling before shipment.

Step 4: UWB Base Station Positioning Accuracy Test

95Power engineers will construct a special indoor positioning environment, and each UWB base station will locate the tested UWB tags in the actual indoor positioning system before shipment. Detect the error radius of tag coordinates, and only UWB base stations that are smaller than the standard can pass the test.

Through the strict indoor positioning product testing process mentioned above, we can ensure that the quality of every UWB base station and tag produced and shipped by Shenzhen Micro Energy Information is qualified.
