simple Introduction:

25 公里传输的距离要求。 This test is based on customer requirements for a transmission distance of 25 kilometers. 27.4 公里,所以超出了客户的测试要求。 However, the effective actual distance of this test is close to 27.4 kilometers, so it exceeds the customer's test requirements. 20/40Mhz 两种模式的实际带宽,以此达到客户的要求。 In this test, we tested the actual bandwidth of the two modes of 20 / 40Mhz to meet customer requirements.

  Test Overview:

Test equipment model

  PTP5-PN (双极) LA- PTP5-PN (bipolar)

Matching antenna

双极蝶形天线 5.8G 32dbi dipole butterfly antenna

to sum up:

     According to the analysis of the results of this test, the transmission we have built and simulated fully meets the customer's actual transmission needs. A/B 个测试点都位于电磁信号复杂的区域,所以在传输过程中会受到同频或者其他信道的干扰。 In the test, since the A / B test points are located in the complex area of electromagnetic signals, they will be interfered by the same frequency or other channels during the transmission process. Therefore, in the actual installation application, the application uses the device's own spectrum scanning function to select a relatively clean channel to use.
