1.1. 

General Features 

The AirPrime AR7594 embedded modules are designed for the automotive industry. They support 
LTE, WCDMA air interface standards and shares hardware and firmware interfaces with the AirPrime 
AR755x and AR758x. They also have Global Navigation Satellite System (GNSS) capabilities 
including GPS and GLONASS.  

The AirPrime AR7594 embedded modules are based on the Qualcomm MDM9640 wireless chipset 
and support the following bands.
