Series Overview

Type 1SC-DM is a new, compact, low cost, LTE-M module that supports the cellular LTE-M & NB1 network protocols.
This new stand-alone module measures just 11.1 x 11.4 x 1.5 mm (max), constructed in a silver resin shielded package and comprises an Altair ALT1250 transceiver with a FEM module and external flash memory.
An integrated TCXO that has robust low drift thermal characteristics provides an accurate clock source for the RF transceiver.

What is “LTE-M”?

LTE-M is the abbreviation for LTE Cat-M1 or Long Term Evolution (4G), category M1.
This technology is for Internet of Things devices to connect directly to a 4G network (Mobile Network Operator – MNO such as AT&T or Verizon, etc.) without a gateway and typically on batteries.
LTE-M which includes eMTC (enhanced Machine Type Communication), is a type of low power wide area network (LPWAN) radio technology standard developed by 3GPP to enable a wide range of cellular devices and services (specifically, for machine-to-machine and Internet of Things applications).
In March 2019, the Global Mobile Suppliers Association reported that over 100 operators had deployed/launched either NB-IoT or LTE-M networks.
LTE-M has a higher data rate, supports mobility, and voice over the network, but requires more bandwidth than NB-IoT, and cannot be put into guard band frequency bands like NB-IoT.

Key Features for LTE-M Technology

- Enables GPS-free, low power periodic tracking applications
- Size attractive to wearables that previously had no means of cellular connectivity
- Through PTCRB/GCF certification improved global interoperability with global wireless networks operators for IoT applications
- Protocol designed specifically for low current consumption extending battery lifetime up to 10+ years
- Ubiquitous connectivity for pennies on the dollar
- Supports HTTPS and MQTTS
- Supports smooth operation in cellular networks for cell-edge and handover scenarios

What is “NB-IoT”?

NarrowBand-Internet of Things (NB-IoT) is a standards-based low power wide area (LPWA) technology developed to enable a wide range of new IoT devices and services.
NB-IoT significantly improves the power consumption of user devices, system capacity and spectrum efficiency, especially in deep coverage.
NB-IoT uses a subset of the LTE standard, but limits the bandwidth to a single narrow-band of 200kHz.

Key Features for NB-IoT Technology

- NB-IoT offers lower bandwidth data connections at and even lower cost, where network latency is not critical for an application
- Through PTCRB/GCF certification improved global interoperability with global wireless networks operators for IoT applications
- Where LTE-M coverage may be lacking, NB-IoT can be used and vice versa, unless security and mobility is critical for you application
