Step 1: Hardware Setup

Setting up the hardware for your GSM/GPRS lab is the first crucial step. Follow these instructions carefully to ensure a proper setup.

1. Assemble the Raspberry Pi 4:
   • Place the Raspberry Pi 4 into its GeekPi case
   • Ensure proper ventilation for the cooling fan
   
2. Connect the NVMe SSD:
   • Attach the NVMe SSD to the Raspberry Pi using the appropriate adapter
   • Ensure a secure connection to avoid data transfer issues
   
3. Set up the LimeSDR:
   • Carefully place the LimeSDR into its protective case
   • Attach the provided antennas to the LimeSDR
   
4. Connect the LimeSDR to the Raspberry Pi:
   • Use the USB Y cable to connect the LimeSDR to the Raspberry Pi
   • The Y cable provides additional power to the LimeSDR
   
5. Ensure proper antenna connections:
   • Verify that the antennas are securely attached to the LimeSDR
   • Position the antennas for optimal GSM frequency reception
6. Set up a Faraday cage (optional but recommended):
   • If available, place your setup inside a Faraday cage
   • This helps isolate your experiments from external signals and prevents unintended interference
