==What are Cellular LTE CatM and NBIoT?==
<br>
[[File: Cellular_logo_nbiot_catm.png |200px|center| Technologies]]<br>

LTE CatM and Narrowband Internet of Things (NBIoT) are low-power wide-area network (LPWAN) radio technology standards developed by 3GPP to enable a wide range of cellular devices and services.
<br>
NBIoT focuses specifically on the indoor coverage, low cost, long battery life, and high connection density.
<br>
The advantage of LTE CatM over NBIoT is its higher data rate, mobility, and voice over the network. However it requires more bandwidth and is more costly.

==Getting started with STM32 and Cellular LTE Cat M and NBIoT==
<br>
''' On hardware point of view''', STMicroelectronics offers various possibilities to setup a STM32 with the Cellular connectivity solution:

<br>


Note that to connect the STMod+ board to the B-L475E-IOT01A IoT Discovery board, an Arduino / STMod+ adapter ('''X-NUCLEO-STMODA1''') is needed.

''' On software side''', the '''X-CUBE-CELLULAR''' (X-CUBE Expansion Package) provides a software solution to allow customers to quickly and easily develop their own Firmware:

* Based on FreeRTOS
* Users can choose whether to use either the IP stack in the modem or in the STM32 (LwIP)
* Menu and command line through Virtual COM UART over USB ST-LINK to configure the cellular connectivity parameters (technology selection, bands, APN, and others), and the connection to the cloud IoT platform (HTTP or MQTT)
* Easy to support a new modem.

Several applications are provided as examples including: PING, ECHO, HTTP, and MQTT.

New hardware setups and new software features in X-CUBE-CELLULAR are to be provided to customers over time.
