Development Scope
Scope and Basic Check
Determine the existing foundation, technical dependencies and content that needs to be developed based on the original module model and firmware, motherboard schematic diagram, deployment area, operator, data business and procurement constraints.
Implementation and integration
Compare frequency bands, interfaces, levels, startup timings, AT behaviors and network capabilities one by one, establish the range that must be modified and can be reused, and then use the target board to confirm the differences.
Delivery Documentation
Output selection comparison, difference list, migration patches and verification records.
Verification and Constraints
Alternatives are confirmed by regional version and supply conditions, and models in the same series cannot be considered to be functionally identical.
Project implementation process
Verification of data and interfaces → Confirmation of technical solutions and verification use cases → Implementation of integration with the target environment → Regression of abnormal scenarios → Transfer of version data.
Verify the implementation results in the target hardware and software environment, and deliver records of associated interface configurations, version dependencies, and problem handling to facilitate subsequent integration and maintenance by the enterprise R&D team.
Project Inputs
- Original module model and firmware, motherboard schematic diagram, deployment area, operator, data service and procurement constraints.
- Design information, code, interface permissions and target test equipment can be provided.
- Source files, programs or tools expected to be delivered, inter-module integration testing responsibilities and project nodes.
- Acceptance samples, environment, test conditions and passing thresholds.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| achieve results | Output selection comparison, difference list, migration patches and verification records. | Check electrical and interface differences. |
| Integrated data | Versions and dependencies, interface configuration, usage or deployment steps, and integration changes | Verify network registration, business connection and abnormal recovery. |
| Verify records | Test conditions, execution records, problem lists and regression results | Record the functional regression results of the old version and the new version. |
The delivery scope and acceptance criteria are determined based on the target environment. Third-party SDK, licenses, laboratories, cloud resources, equipment materials and on-site support are listed separately; when the existing information is insufficient, follow-up work will be determined through interface verification or key function verification.
Frequently Asked Questions
Does module package compatibility mean direct replacement?+
Package or pin compatibility can only be used as an entry point for evaluation. Power supply, multiplexed pins, firmware commands, drivers and network versions may still be different, and need to be returned according to the target module data and actual business.
4G What information do I need to provide first for module selection and replacement?+
Please give priority to providing the original module model and firmware, motherboard schematic diagram, deployment area, operator, data service and procurement constraints. At the same time, the existing implementation, problems encountered, expected changes, and compatible test conditions are explained to facilitate the determination of implementation scope and reproduction methods.
Can it be implemented on existing products?+
You can first evaluate the scope of existing designs and versions that can be changed, retain the verified parts, and determine the interfaces and dependencies that need to be adjusted. This service requires attention: Alternatives are confirmed by regional version and supply conditions, and models in the same series cannot be considered to have identical functions. Existing and new functions must undergo regression testing within the agreed scope after the changes.
