GSM/GPRS/GNSS Module Series MC60 Hardware Design In all-in-one solution, the MC60 works as a whole unit. The GNSS Part can be regarded as a peripheral of the GSM Part. This allows for convenient communication between GSM and GNSS Parts, such as AT command sending for GNSS control, GNSS part firmware upgrading, and EPO data download. In stand-alone solution, GSM and GNSS Parts work independently, and thus have to be controlled separately.

GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.4. Operating Modes 3.4.1. Operating Modes of GSM Part The table below briefly summarizes the various operating modes of GSM part mentioned in the following chapters.
PAGE 36
GSM/GPRS/GNSS Module Series MC60 Hardware Design case is very low. Based on system requirements, there are several actions to drive the GSM part to enter into low current consumption status. For example, AT+CFUN can be used to set the part into minimum functionality mode, and DTR hardware interface signal can be used to lead the system to Sleep Mode. 3.4.1.1. Minimum Functionality Mode Minimum functionality mode reduces the functionality of the GSM part to a minimum level.
PAGE 37
GSM/GPRS/GNSS Module Series MC60 Hardware Design 3.4.1.3. Wake up GSM Part from SLEEP Mode When the GSM part is in the SLEEP mode, it can be woken up through the following methods:    If the DTR Pin is set low, it would wake up the GSM part from the SLEEP mode. The UART port will be active within 20ms after DTR is changed to low level. Receiving a voice or data call from network wakes up the GSM part. Receiving an SMS from network wakes up the GSM part.

Up to 12 multi-tone AIC embedded in the module can provide effective narrow-band interference and jamming elimination. The GNSS signal could be demodulated from the jammed signal, which can ensure better navigation quality. AIC function is enabled by default.

GSM/GPRS/GNSS Module Series MC60 Hardware Design MC60 provides an RF antenna pad for antenna connection. The RF trace in host PCB connected to the module’s RF antenna pad should be coplanar waveguide line or microstrip line, whose characteristic impedance should be close to 50Ω. MC60 comes with grounding pads which are next to the antenna pad in order to give a better grounding. Besides, a π type matching circuit is suggested to be used to adjust the RF performance.
