LTE module with 2G fallback

21 February 2018 Telecoms, Datacoms, Wireless, IoT

u-blox released SARA R412M, an LTE Cat M1, NB IoT and quad-band 2G (EGPRS) module with worldwide coverage. Measuring just 16 x 26 mm, the module can operate in Cat M1, NB IoT or EGPRS single mode, or as a preferred connection that does not require a module reboot to switch between modes. It allows developers to select their own desired frequencies and operator configurations, and ensures data integrity between applications via secure communication protocols, notably including two-way authentication between client and server, a strategy often utilised with cloud services. Critical firmware updates can be delivered with over-the-air updates that utilise LWM2M, a light and compact protocol that is ideal for IoT applications.
