Text and PDU mode*
Low power consumption: Supports PSM and eDRX modes. In theory, two No. 5 batteries can support 10 years;
High sensitivity: Compared with the existing cellular technology, it has 20dB gain coverage, wide signal coverage and strong penetrating power. The products using this module still have wireless communication capability in indoor or basement locations;
High-density deployment: A targeted design allows a community to maintain up to 50,000 terminals;
Support user independent research and development: consider adding a single-chip microcomputer in the design of the development board for customers to design related functions according to their own needs, and can independently develop various functions;
The compact SMT package meets the tight space requirements of end applications;
LCC package: support mass production, easy to maintain.
