Replaceable Models and Key Differences
As specified in the document E840-TTL(EC05-xxx) User Manual_v1.2.pdf, the following three models are compatible but require attention to their distinctions:
1. E840-TTL(EC05-DNC)
Version: Domestic (China) version
Supported Frequency Bands:
LTE-TDD: B34/B38/B39/B40/B41; LTE-FDD: B1/B3/B5/B8Positioning Function: Does not support GNSS positioning.
Applicable Region: Primarily for the Chinese market.
2. E840-TTL(EC05-DGC)
Version: Domestic (China) version (with positioning)
Supported Frequency Bands: Same as EC05-DNC.
Positioning Function: Supported. Integrates GPS/BDS/Galileo/GLONASS for combined positioning; location can be queried via AT commands or reported via heartbeat packets.
Applicable Region: Primarily for the Chinese market, specifically scenarios requiring positioning.
3. E840-TL(EC05-DNE)
Version: Europe & Asia version
Supported Frequency Bands: LTE-FDD: B1/B3/B5/B7/B8/B20/B28
Positioning Function: Does not support GNSS positioning.
Applicable Region: Europe, Southeast Asia, and other regions.
Decision Guidelines Based on Scenarios:
For projects in China requiring GPS/BDS positioning: Select E840-TTL(EC05-DGC).
For projects in China without positioning needs: Select E840-TTL(EC05-DNC).
For projects in Europe or Southeast Asia: Select E840-TL(EC05-DNE).
Final Recommendation
Before selecting a replacement model, verify your device’s required carrier frequency bands and functional requirements (e.g., positioning).
Cross-reference the parameters of each model in the document to ensure
network compatibility and functional suitability for your project.
