The testing process for wireless communication equipment typically includes the following steps:
1. Project Application: Submit a test application to the testing agency, specifying the testing requirements and standards.
2. Report Planning:Plan significant test records and materials concurring to the testing necessities, counting gadget manuals, circuit graphs, etc.
3. Gear Calibration:Calibrate the testing gear to guarantee the precision and unwavering quality of the test comes about.
4. Test Environment Setup:Set up the comparing test environment agreeing to the testing necessities, counting obstructions situations, multipath situations, etc.
5. Test Execution:Conduct different execution tests on the remote communication gear concurring to the test arrange and measures, and record the test comes about.
6. Result Examination:Analyze the test comes about to assess the execution and unwavering quality of the gear, and give recommendations for change.
7. Report Composing:Compile the test comes about into a report, assessing the execution and unwavering quality of the hardware.
Common testing methods for wireless communication equipment include:
1. Transmission Power Test: Measure the power of the signal transmitted by the device.
2. Reception Sensitivity Test: Measure the sensitivity of the device to received signals.
3. Interference Resistance Test: Test the communication performance of the device in an interference environment.
4. Bit Error Rate Test: Measure the bit error rate during transmission.
5. Field Strength Test: Measure the field strength of the signal around the device.
Wireless communication testing equipment and testing conditions are crucial for ensuring the performance and reliability of communication devices. Here are some common wireless communication testing equipment and conditions:
1. Flag Generator:Utilized to create test signals to mimic distinctive communication scenarios and obstructions conditions.
2. Range Analyzer:Utilized to degree the range and control of signals to assess the transmission and gathering execution of the gadget.
3. Organize Analyzer:Utilized to test the arrange parameters of the gadget, such as pick up, misfortune, reflection, etc.
4. Radio Communication Analyzer:Coordinating numerous testing capacities and can be utilized to degree different execution markers of the gadget.
Test site introduction:
1. Open Field: Used for radiation testing, suitable for tests at different frequencies. Normal test separations are 3 meters, 5 meters, 10 meters, and 30 meters. The measure of the hardware (barring radio wires) ought to be less than 20% of the test separate. The height of the equipment or substitute antenna should be 1.5 meters, and the height of the test antenna should be between 1 and 4 meters. The total size of the open field should be about 2 to 3 times the test distance.
2. Anechoic Chamber: A shielded room covered with RF-absorbing material that simulates a free-space environment. It can be used as an alternative method for radiation testing. The test antenna, equipment under test, and substitute antenna should be used in the same way as in the open field, but must be at the same height above the ground. The anechoic chamber should meet the requirements for shielding loss and wall return loss.
3. Stripline Setup: RF coupling device that couples an integrated antenna to a 500Ω RF terminal. It can perform radiation testing in a non-open field but has a limited frequency range. Both absolute and relative tests can be performed.
In summary, the testing process for wireless communication equipment needs to be strictly followed according to the testing standards and procedures to ensure the accuracy and reliability of the test results.
