-The SIM7080 series is the LPWA module which supports wireless communication modes of Cat-M/Cat-NB.
7
-
8
-The SIM7080 series adopts LCC and LGA form factor and has a compact size of 17.6mm*15.7mm which makes it ideal for compact products design.
9
-
10
-The SIM7080 series has powerful expansibility with abundant interfaces including UART, GPIO, PCM, SPI, I2C etc.
11
-
12
-The SIM7080 series is designed for applications that need low latency, low throughput data communication in a variety of radio propagation conditions.
13
-
14
-Due to the unique combination of performance, security and flexibility, this module is ideally suited for M2M applications, such as metering, asset tracking, remote monitoring, E-health etc.

+LTE Cat NB1,
31
+
32
+also known as Narrowband IoT (NB-IoT) is a Low Power Wide Area (LPWA) technology that has been developed to enable a wide range of devices to be connected to the internet using existing mobile networks. NB-IoT has been developed to enable the Internet of Things (IoT). It is a low power, narrowband technology that can support small amounts of 2-way data transmission in an efficient, secure, and reliable manner. This standard was created in **3GPP Release 13**.

+LTE Cat NB2
35

36
+is an upgraded version of the LTE Cat NB1 standard (NB-IoT). **In Release 14**, 3GPP introduced an enhanced NB-IoT protocol and a new device category called NB2.
