EC2x&EG9x LTE modules Power Management Application Note
■When Quectel LTE modules are embedded into a host system, it will increase the whole power consumption of the system. Therefore,we provide several power management solutions on Quectel LTE modules, thus allowing the host to reduce the overall power consumption through managing the LTE module's power consumption.
■Quectel LTE module power management solutions mainly includethe following aspects:
▲Sleep and wakeup mechanism of the host system (e.g. USB driver suspend and remote wakeup).
▲Physical connection between the module and the host.
▲Sleep and wakeup software mechanism of Quectel LTE modules.
■The following chapters will illustrate Quectel LTE modules' hardware interfaces and URC events relating to sleep and host-wakeup modes, power save solutions for some typical application scenarios, and the modules' sleep and host-wakeup software mechanism.
■This document is applicable to the following Quectel LTE modules:
▲EC2x (EC21, EC25, EC20 R2.0,EC20 R2.1)
▲EG9x (EG91, EG95)
