LTE Cat 4 Module

LTE Cat 4 Module

SC20 SOM (System on Module) is SANDS new generation of multi-mode Smart LTE Cat 4 module with built-in Android OS.

SC20 SOM delivers maximally 150Mbps downlink and 50Mbps uplink data rates based on LTE network, and additionally supports wireless communication via IEEE 802.11 a/b/g/n (IEEE 802.11 b/g/n for SC20-CE/SC20-W by default) and BT4.1 LE (BT4.2 on Android 7.1 or later versions). It is ideal for both industrial and consumer applications requiring high data rate and high-speed internet access. SC20 SOM is backward-compatible with existing EDGE and GSM/GPRS networks, ensuring that it can be connected even in remote areas devoid of 3G or LTE coverage.

The module combines high-speed wireless connectivity with embedded multi-constellation and high-sensitivity GNSS (GPS, GLONASS and BeiDou) receiver for positioning.

A rich set of interfaces (such as LCM, Camera, Touch Panel, MIC, SPK, UART, USB, I2C) extend the applicability of the SOM to a wide range of M2M applications, such as MID, PND, POS, router, data card, DCU, AMR, in-vehicle solutions, smartphone, digital signage, security and industrial PDA.
