Miniature modem provides global LTE-M network coverage
The new Type 1SC cellular network module from Murata provides a ready-made radio system for machine-to-machine connectivity over LTE-M mobile phone networks, and has certificates for operation in most countries worldwide.
The Type 1SC from Murata is a new, compact wireless module which acts as a modem for connectivity with LTE-M cellular networks.
A stand-alone module which operates via an external antenna, the Type 1SC measures just 11.1 mm x 11.4 mm x 1.5 mm. Based on the Altair ALT1250 chipset, the module is supplied in a silver resin shielded package. An integrated precision oscillator with low thermal drift provides an accurate clock source for the RF transceiver.
This Murata modem supports the low and mid bands used in LTE-M networks, and conforms to the specifications of the 3GPP release 17 standard for LTE-M and non-terrestrial networks (NTN). Providing Transmit power of +23 dBm, the modem is optimized for LTE Class 3 applications.
This Murata module is notable for its low sleep mode power consumption. In eDRX mode, average current is 43 µA. In PSM mode, it is 1.4 µA, supporting battery life of more than 10 years.
LTE-M is the abbreviation for the LTE Cat-M1 protocol. This technology enables IoT devices to connect directly to a 4G network without a gateway, and supports operation on battery power.
LTE-M is a type of low-power wide-area network (LPWAN) radio technology which enables a wide range of cellular devices and services, especially for machine-to-machine communication and the IoT. Compared to an NB-IoT network, LTE-M has a higher data rate and supports mobility, but requires more bandwidth, and unlike NB-IoT cannot be put into guard band frequency bands.
The Type 1SC modem can be ordered with LBAD0XX1SC series part numbers. It is supplied in a surface-mount LGA package.
