Hello! Both the SIM808 and SIM868 are popular choices for GPS and GSM modules in IoT devices. Here are some key points to consider when choosing between the two:
1. SIM808:
- The SIM808 is a 2G module that supports both GPS and GSM functionalities.
- It operates on the 850/900/1800/1900 MHz bands for GSM/GPRS and features a built-in GPS receiver.
- It is a reliable and cost-effective option for projects that do not require high-speed data transfer.
- However, please note that 2G networks are being phased out in some regions, so it may not be a future-proof choice.
2. SIM868:
- The SIM868 is an upgraded version that supports both 2G and 4G LTE Cat.M1 (eMTC) connectivity, in addition to GPS functionality.
- It operates on a wider range of frequencies, including LTE bands, making it suitable for regions transitioning to 4G networks.
- The SIM868 offers faster data transfer speeds compared to the SIM808, which can be beneficial for IoT applications that require real-time communication or large data transfers.
- However, the SIM868 may be slightly more expensive than the SIM808 due to its advanced features.
In summary, if you are looking for a cost-effective solution and 2G network compatibility is not an issue in your region, the SIM808 could be a suitable choice. On the other hand, if you want a more future-proof option with faster data transfer speeds and LTE support, the SIM868 may be a better fit for your IoT device.
I hope this information helps you make an informed decision for your project. Good luck with your system development, and feel free to ask if you have any more questions!
