The ME910C1 is the Category M1/NB1 evolution of the Telit LE910 Series of LTE modules. Specified in the approved Release 13 of the 3GPP standard, Cat M1/NB1 devices are specifically tailored for IoT applications, offering optimized power consumption and enhanced coverage. This model further enriches the widely deployed Telit xE910 family of 28 x 28 mm LGA modules.
The xE910 family is now offering NB1 only but also M1 / NB1 dual mode with 2G fall-back with the comming version ME910C1-E2. It is also possible to have GNSS (GPS / Glonass /Beidou etc..) in the same module. Samples are expected in October 2017 for the first applications and rapid development.
