SC20 series is Quectel's new generation of multi-mode Smart
LTE Cat.4 modules with built-in Android 5.1 Lollipop OS. It sup-
ports short-range wireless communication via Wi-Fi 802.11b/g/n
and BT4.1 LE, and offers data rate up to 150Mbps. It is ideal for
Quectel Enhanced
both industrial and consumer applications requiring the highest
AT Commands
data-rate and high-speed internet access.
SC20 series comes in five variants: SC20-CE, SC20-E, SC20-A,
SC20-AU and SC20-J. This makes it backward-compatible with
existing EDGE and GSM/GPRS networks, ensuring that it can
be connected even in remote areas devoid of 3G or LTE cover-
age.
SC20 features multiple-input multiple-output (MIMO) technology,
a cutting edge antenna technology capable of transmitting multi-
ple data streams on multiple transmitters to multiple receivers.
The antennas at each end of the communications circuit are
combined to minimize errors and optimize data speed. The
module also combines high-speed wireless connectivity with
embedded
GLONASS+BeiDou receiver for positioning.
A rich set of interfaces (such as LCM, Camera, Touch Panel,
MIC, SPK, UART, USB, I2C) and abundant drivers (USB driv-
ers for Windows XP, Windows Vista, Windows 7, Windows
8/8.1, Linux) extend the applicability of the module to a wide
range of M2M applications, such as CPE, wireless POS, smart
metering, router, data card, automotive, smart phone, digital
signage, alarm panel, security and industry PDA.
