Pre-certified M2M Modem Dock for Rapid Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing M2M wireless systems face lengthy and expensive certification processes, requiring third-party testing and semi-permanent modem installation, which complicates repairs and replacements, and incurs significant costs for network operators.
Innovation Solution
A pre-certified M2M modem dock that simplifies the integration with M2M devices, allowing for removable and easily replaceable modems, reducing the need for repeated certification and enabling cost-effective communication solutions by being pre-tested and certified before use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each modem is tested and certified individually to the wireless/cellular network system, then the integration of the modem with the machine is ensured, but the testing procedure becomes lengthy and expensive
Solution Approach 1:
The modem is pre-tested and certified in a controlled environment before being installed in the M2M device. This preliminary certification action eliminates the need for time-consuming on-site testing at the customer location, while still ensuring reliable integration through thorough pre-validation of communication protocols and hardware compatibility.
2Stability of the object's composition
If the wireless modem is soldered onto the circuit board, then the modem becomes semi-permanent to the machine, but repair or replacement becomes involved and complex
Solution Approach 1:
The modem is designed as a separate, removable component that interfaces with the M2M device through standardized connectors rather than being permanently soldered. This segmentation allows the modem to be easily removed and replaced if malfunction occurs, while maintaining stable electrical and mechanical connections through robust connector design. The modem can be swapped as a complete module without affecting other device components.
3Reliability
If the M2M system is recertified after hardware changes or original failure, then the system compliance is maintained, but the certification cost increases significantly
Solution Approach 1:
The modem is certified and compliant with wireless/cellular network requirements before being integrated into the M2M device. This preliminary certification ensures that the device maintains compliance even after hardware changes or replacements, as the certified modem module can be reinstalled without requiring recertification of the entire system. The certification is attached to the modem module itself, not the specific device installation.

AI summary
A wireless network modem dock having a case that houses circuitry and a power connector, a data interface, and a user identification reader all connected to the circuitry. In addition, an antenna connector is attached to the case and connected to the circuitry. The circuitry is capable of sending and receiving M2M data through the antenna connector to a wireless network. Further, the case, the circuit, the power connector, the data interface, the user identification reader, and the antenna connector are certified with the wireless network prior to sending or receiving the M2M data.
