SARA-G3 and SARA-U2 series
GSM/GPRS and GSM/EGPRS/HSPA
Cellular Modules
System Integration Manual
Abstract
This document describes the features and the system integration of
the SARA-G3 series GSM/GPRS cellular modules and the SARA-U2
GSM/EGPRS/HSPA cellular modules.
These modules are complete and cost efficient solutions offering
voice and/or data communication over diverse cellular radio access
technologies in the same compact SARA form factor: the SARA-G3
series support up to four GSM/GPRS bands, while the SARA-U2
series support up to five high-speed HSPA bands and up to four
GSM/EGPRS bands.
