Simulate low network connectivity for Android

This may sound a little crazy, but a microwave oven serves as a microwave shield. Therefore, putting your device inside a microwave oven (DO NOT turn on the microwave oven while your device is inside!) will cause your signal strength to drop significantly. It definitely beats standing inside an elevator...

You can use emulator for this. Take a look at this page: Android Emulator. Pay attention to next two arguments:

1. -netdelay <delay>

   Set network latency emulation to . Default value is none. See the table in Network Delay Emulation for supported values.

2. -netspeed <speed>

   Set network speed emulation to . Default value is full. See the table in Network Speed Emulation for supported values.

   Speeds for reference in increasing kbps:
