02-08-2021 | RS Components | Subs & Systems

The Siretta SL500-LTE1 (EU) modem, available now from RS Components, is a low power LTE Cat 1 modem that is employed to create a data connection over the LTE cellular network to link a remote application with a server. It offers an intelligent serial gateway, shifting away from the conventional approach of setup and management using AT commands which need a high skill level to implement correctly.

The modem utilises an embedded STM32F405 ARM Cortex M4 core processor to implement advanced functionality. This runs an application that connects the modem to the SirettaLINK Management Portal utilising an encrypted link, where it downloads the configuration profile for connecting to the customer’s specified resource and posts operational data.

The modem offers six bands: 4G/LTE: B1(2100), B3(1800), B7(2600), B8(900), B20(800), B28A(700) MHz; three bands: 3G/UMTS B1(2100), B3(1800), B8(900) MHz; two bands: 2G/GSM | GPRS: B3(1800), B8(900).
