Note
：
SIMCom suggests the LTE auxiliary antenna to be kept on, since there are many high
bands in the designing of TDD-LTE, such as band38, band40 and band41. Because of the high
insert loss of the RF cable and layout lines, the receiver sensitivity of these bands above will have
risk to meet the authentication without the diversity antenna. For more details about auxiliary
antenna design notice, please refer to document [25].
4.3 GNSS
SIM7600SA-H merges GNSS (GPS/GLONASS) satellite and network information to provide a
high-availability solution that offers industry-leading accuracy and performance. This solution
performs well, even in very challenging environmental conditions where conventional GNSS
receivers fail, and provides a platform to enable wireless operators to address both location-based
services and emergency mandates.
4.3.1 GNSS Technical specification
Tracking sensitivity: -159 dBm（GPS）/-158 dBm（GLONASS）
Cold-start sensitivity: -148 dBm
Accuracy (Open Sky): 2.5m (CEP50)
TTFF (Open Sky) : Hot start <1s, Cold start<35s
