Software Configuration
To set up your Raspberry Pi for 4G connectivity, you’ll need to install the necessary drivers and configure the settings. Start by updating your Raspberry Pi’s package list and upgrading any installed packages to their latest versions. Next, install the required USB modeswitch and usb-modeswitch-data packages, which enable the Raspberry Pi to recognize and communicate with the 4G USB modem. Once the packages are installed, plug in your 4G USB modem to the Raspberry Pi. Use the lsusb command to verify that the modem is detected. You may need to configure the modem using usb_modeswitch to switch it from storage mode to modem mode. After the modem is recognized, install the PPP (Point-to-Point Protocol) software, which enables the Raspberry Pi to establish a connection with the 4G network. Edit the PPP configuration files, such as /etc/ppp/peers/provider and /etc/ppp/chatscripts/3gprovider, to specify your mobile network’s APN settings and authentication details. Next, install the wvdial package, which simplifies the process of establishing a PPP connection. Create a configuration file named /etc/wvdial.conf with your modem’s device name, baud rate, APN, and authentication information. Save the file and run wvdial to initiate the 4G connection and provide internet access. Finally, configure your Raspberry Pi to automatically connect to the 4G network on boot by editing the /etc/network/interfaces file. Add the necessary lines to define the PPP interface and specify the wvdial configuration file. With these steps completed, your Raspberry Pi should now be set up to connect to the 4G network automatically whenever it is powered on and the 4G USB modem is plugged in.
5 Innovative Projects Using 4G and Raspberry Pi
Portable 4G Wi-Fi Hotspot
To create a portable 4G Wi-Fi hotspot using a Raspberry Pi, you’ll need a 4G-compatible HAT or USB modem. Once you have the hardware, install the necessary software packages, such as sakis3g or wvdial, to configure the modem. Set up the connection using the appropriate APN settings provided by your mobile network operator. Next, configure your Raspberry Pi to act as a Wi-Fi access point using hostapd and dnsmasq. This will allow other devices to connect to your Pi and access the internet through the 4G connection. You can also set up a basic web interface using a lightweight web server like lighttpd to monitor the connection status and manage connected devices. With your portable 4G Wi-Fi hotspot ready, you can now take your Raspberry Pi on the go and enjoy internet connectivity wherever you have cellular coverage. This setup is particularly useful for remote projects, such as weather stations or wildlife cameras, where a reliable internet connection is required but traditional Wi-Fi networks are unavailable. It’s also a great way to share your 4G connection with multiple devices without the need for additional hardware.
Remote Surveillance Camera
Transform your Raspberry Pi into a versatile security camera with 4G connectivity for remote monitoring. By leveraging the power of 4G, you can deploy your Raspberry Pi camera in locations without Wi-Fi access, making it ideal for outdoor surveillance or monitoring remote properties. To get started, you’ll need a Raspberry Pi board, a compatible camera module, and a 4G HAT or USB modem. Set up the hardware and configure the software to enable 4G connectivity and live streaming capabilities. You can then access the camera feed remotely using a web browser or a dedicated mobile app, allowing you to keep an eye on your property from anywhere with an internet connection. With motion detection and alerts, you’ll be instantly notified of any activity, ensuring your property remains secure. This project showcases the versatility of the Raspberry Pi and how 4G technology can be harnessed to create powerful, remote monitoring solutions.
IoT Weather Station
Building a solar-powered weather station with 4G data transmission using a Raspberry Pi is an exciting project for tech enthusiasts and hobbyists.

Next, set up a 4G HAT or USB modem compatible with your Raspberry Pi to enable cellular connectivity. Configure the device to send the collected weather data to a remote server or cloud platform at predetermined intervals. This allows you to access and analyze the data from anywhere with an internet connection. With proper power management and optimized data transmission, your IoT weather station can operate autonomously for extended periods, providing valuable insights into local weather patterns and conditions.
Vehicle Tracking System
With a 4G Raspberry Pi, you can create a powerful vehicle tracking system that provides real-time location data. By combining a GPS module and a 4G cellular modem, you can transmit location information from the vehicle to a central server or database. Start by connecting the GPS module to the Raspberry Pi’s GPIO pins and configuring it to retrieve latitude and longitude coordinates. Next, set up the 4G modem to establish a connection to the cellular network, enabling data transmission. Write a Python script that reads the GPS data and sends it to a remote server using the 4G connection at regular intervals. On the server side, store the received data in a database and use a web-based interface or mobile app to display the vehicle’s location on a map in real-time. You can enhance the system by adding features like geofencing alerts, speed monitoring, and route tracking. This project showcases the potential of 4G Raspberry Pi in creating IoT solutions for fleet management, logistics, and personal vehicle tracking, offering valuable insights for businesses and individuals alike.
