Notes:

1. Y = supported (including LTE and UMTS)

2. 1) B2 band on EC21-AU/EC25-AU module does not support Rx-diversity.

 

The M2M market is developing fast. And those players must face kinds of problems such as technologies improving, customize inquiry, or different standards in different regions of the world. So compatible design is necessary for M2M modules to realize fast time to market and save development costs to lower total product cost.

 

Quectel EC2x series and EG25-G are footprint-compatible with UCxx modules, offering a backward and forward compatibility. Users will benefit from the scalable product design and simplify design reuse.
