#WIFI INTERFERENCE TESTING MAC#

The testing standard for Wi-Fi throughput drop rate is listed as below:.

The throughput of the strong RSSI level should be better than that of the weak RSSI level.

The laptopвЂ™s Wi-Fi throughput when plugging a USB device should be better than that throughput when unplugging a USB device.

Test each USB-C ports of the system (laptop).

Once the drop rate meets the testing standard spec, it can ensure that users will enjoy stable wireless performance of a laptop when connecting to a USB dongle.

Confirm the W-Fi throughput drop rate (the throughput difference) falls below the standard range.

Measure Wi-Fi Tx and Rx throughput difference between the laptop with and without a USB 3.1 dongle.

To avoid interferenceВ caused by by other factors, the test bed, the digital attenuator and the AP are placed in the individual shielding room or shielding box. To verify the dense wonвЂ™t downgrade the laptop performance when plugging the USB-C device. Now, we are going to share the test case studies with you. No matter your product is a system, a USB accessory or a BluetoothВ® accessory, our RF Testing lab could help you ensure the quality, and further establish a good reputation in the industry. In order to solve USB 3.1 wireless interference issues, Allion has proposed the Wireless De-sense testing solution. Reference Source: Intel Document: 327216-001 P.9 It eventually turns to poor wireless network quality. The closer the distance is, the more serious the interference is, the higher possibility that the systemвЂ™s wireless receiver sensitivity would be affected.

The distance between Wi-Fi antenna and the signal radiation of USB3.1 will determine how serious interference is. The signal interference of USB3.1 may generate from the connector, the cable or the device itself. Reference Source: Intel Document: 327216-001 P.10 As the below illustration shows, the average noise level (with the condition that a USB3 device is connected) is 20 dBm higher than the level (with the condition that a USB3 device is not connected.) It demonstrates the interference is easily generated between the high-speed transmission interface and Wi-Fi (or BluetoothВ®) 2.4 GHz signal, when connecting USB3 device to the system. LetвЂ™s elaborate more about De-sense issues.

ThatвЂ™s why we hear that a few Mac users complain their Mac systems get weak Wi-Fi signal or disconnecting Wi-Fi when connecting a USB-C Docking. The common Wireless De-sense issue occurs when connecting a USB 3.1 Device (e.g. Since manufacturers make devices lighter and thinner, the radiated interference was easily caused by components will lower signal-to-noise ratio and wireless throughput in a tiny space. One of the common RF interference issues is caused by De-sense, which we want to discuss today. 5G, W-Fi, and BluetoothВ®) makes our lives easier, but also brings various wireless signal interference issues. The rapid growth and the pervasive uses of wireless communication technologies (e.g.
