我很惊讶没人提到这一点。你可以通过蓝牙连接，并将它们分开十多米(或更少的障碍物)。你的信号很差。没有微波炉，没有电梯，不需要软件。

Facebook建立了一个叫做增强交通控制的东西。GitHub页面上的简要总结:

Augmented Traffic Control (ATC) is a tool to simulate network conditions. It allows controlling the connection that a device has to the internet. Developers can use ATC to test their application across varying network conditions, easily emulating high speed, mobile, and even severely impaired networks. Aspects of the connection that can be controlled include: bandwidth latency packet loss corrupted packets packets ordering In order to be able to shape the network traffic, ATC must be running on a device that routes the traffic and sees the real IP address of the device, like your network gateway for instance. This also allows any devices that route through ATC to be able to shape their traffic. Traffic can be shaped/unshaped using a web interface allowing any devices with a web browser to use ATC without the need for a client application.

你可以在GitHub上找到它:https://github.com/facebook/augmented-traffic-control

他们还为此写了一篇博客:https://code.facebook.com/posts/1561127100804165/augmented-traffic-control-a-tool-to-simulate-network-conditions/

运行>运行配置，选择Android应用程序，然后进入目标选项卡。按照图中所示进行更改。

你也可以在真正的android设备上测试慢速互联网连接:

在三星Galaxy S8 + Android 8.0.0上测试

进入设置->连接->移动网络->，在网络模式下，你可以选择只使用2G或3G连接

由于iPhone开发者选项适用于wifi绑定，你可以获得一部iOS 6及以上版本的iPhone(并已被设置为使用xcode开发)，将其设置为模拟所需的网络配置文件，将你的Android设备连接到它的热点
