This is a wireless communication module, integrated an M8321 module that released by China Mobile, provided TD-LTE/FDD-LTE/WCDMA/TD- SCDMA/GSM/GPRS/EDGE Frequency Band and LCC+LGA package type. 
It has integrated plentiful Internet protocols, field standard interface, and functions, supported WindowsXP、Windows7 、Windows8、 Windows10、Linux and Android USB driver. 
In the LTE-4G module scheme, we added more hardware resources, 1 reserved speaker solder panel, 3 LEDs, exported USB interface, double antennea allowed. 
M8321 is 4V power input, so in the hardware of LTE-4G module, we added a Bidirectional Voltage-Level Translator (TXS0104E), to switch the power supply to 4V.


In telecommunication, Long-Term Evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements.

ARIB approval ?

This product covers B1/3/8 of FDD-LTE. So, it may work in Japan properly.
Technically, it's no problem. How about the approval of ARIB ?
