2.1. General Description
SC20 is a series of Smart LTE module based on Qualcomm platform and Android operating system, and
provides industrial grade performance. It supports worldwide LTE-FDD, LTE-TDD, DC-HSDPA, HSPA+,
HSDPA, HSUPA, WCDMA, TD-SCDMA, CDMA, EDGE and GPRS coverage, and also supports
short-range wireless communication via Wi-Fi 802.11a/b/g/n and BT4.1 LE. Additionally, SC20 integrates
GPS/GLONASS/BeiDou satellite positioning systems. Due to multiple speech and audio and video
codecs as well as the built-in high performance Adreno
TM
304 graphics processing unit, it enables smooth
play of 720P videos. The module also offers multiple audio and video input/output interfaces as well as
abundant GPIO interfaces.
SC20 module contains five variants: SC20-CE R1.1, SC20-E, SC20-A, SC20-AU and SC20-J. The
following tables show the supported frequency bands and network standards of SC20.
