[0002] Wireless routers have been developed since the 1990s. Whether it is design and development or production and testing, they are all very mature technologies. The overall profit of the industry is becoming increasingly slim. At this stage of the price increase of electronic components, how to improve production efficiency and reduce costs in production and testing is an issue that all manufacturers must consider.

[0003] Traditional wireless router production testing includes two parts: board testing and final testing. The board testing mainly involves performance coupling testing, and performance coupling indicators include receiving sensitivity, transmission power, spectrum, frequency deviation, etc. The terminal testing mainly involves data throughput testing of wireless networks (WiFi, Wireless Fidelity). Traditional board testing requires connecting the wireless router motherboard to external testing instruments through wires to test various indicators before the wireless router is fully assembled, while final testing involves throughput testing after the entire machine is assembled. In actual production, two workstations need to be set up for board testing and final testing, which require two employees to operate. This results in low production efficiency, complex operation, high labor costs, and the inability to guarantee spatial attenuation consistency during batch testing. Utility Model Content
