General Description
2.1 Overview
EG91 mini PCIe is a series of LTE category 1 modules adopting standard PCI
Express Mini Card form factor (Mini PCIe). It is optimized specially for M2M
and IoT applications and delivers 10Mbps downlink and 5Mbps uplink data rates.
EG91 mini PCIe supports Qualcomm® IZat™ location technology Gen8C Lite (GPS,
GLONASS, BeiDou, Galileo, and QZSS). The integrated GNSS greatly simplifies
product design and provides quicker, more accurate, and more dependable
positioning.
A rich set of Internet protocols, industry-standard interfaces, and abundant
functionalities (USB serial drivers for Windows 7/8/8.1/10, Linux, Android)
extend the applicability of the module to a wide range of M2M applications
such as an industrial router, industrial PDA, rugged tablet PC, video
surveillance, and digital signage.

2.13 Operating Models
The following table briefly outlines the operating modes to be mentioned in
the following chapters.
| Mode | Detail |
|---|---|
| Normal Operation | idle |
network, and it is ready to send and receive data
Talk/Data| The network connection is ongoing. In this mode, the power
consumption is decided by network setting and data transfer rate.
Minimum Functionality Mode| AT+CFUN command can set the module to a minimum
functionality mode without removing the power supply. In this case, both the
RF function and (U)SIM card will be invalid.
Airplane Mode| AT+CFUN command or W_DISABLE# pin can set the module to
airplane mode. In this case, the RF function will be Invalid.
Sleep Mode| In this mode, the current consumption of the module will be
reduced to a minimal level. In this mode, the module can still
receive paging message, SMS, voice call, and TCP/UDP data from the network
normally
Power Down Mode| In this mode, the power management unit shuts down the power
supply. The software goes inactive. The serial interface is not accessible.
Operating voltage remains applied
2.14 Power Saving
2.14.1 Sleep Mode
EG91 Mini PCIe can reduce its current consumption to a minimum value in sleep
mode. There are three preconditions that must be met to make the module enter
sleep mode.
- Execute AT+QSCLK=1 to enable sleep mode
- Ensure the DTR is kept at a high level or be kept open
- The host’s USB bus, which is connected with the module’s USB interface, enters suspend state
2.15 Airplane Mode
When the module enters airplane mode, the RF function will be disabled, and
all AT commands related to it will be inaccessible.
