Option 1: Connect the mobile device to the PC for weak network testing
For example, use Fiddler, Charles, NET-Simulator, etc.
(Take Fiddler as an example) The basic idea is to install a network packet capture tool on the PC, then proxy the network of the mobile device to the PC, and simulate a weak network by setting a delay in Fiddler on the PC.
Solution 2: Build weak network WiFi on a dedicated server
Use a mobile device to connect to the WiFi to conduct weak network testing. Relevant technical solutions include Facebook's ATC and Tencent's WeTest-WiFi.
Option 3: Qnet
Tencent's independent APP does not require a PC. To download, you need to enter the official website and contact customer service.
