AT&T has certified what it is claimed to be the world's smallest form factor LTE-M and NB-IoT module for operation on its 4G LTE wireless network. The module was jointly produced by Japan-based Murata Electronics and Sony subsidiary Altair Semiconductor.
The module enables applications such as dual-mode cellular IoT. In addition to its size, low power and cost-efficiency, the type 1SC's level of integration can cut time to market and reduce certification costs.
The module is powered by Altair's ALT1250, a cellular IoT chipset providing what is claimed to be the market's lowest power consumption, enabling the longest battery life for cellular IoT. Commercially available, the chipset has a hardware-based security framework and a set of features including integrated SIM (iUICC), MCU and GNSS, suitable for integration in industrial and consumer IoT applications.
Measuring 11.1 by 11.4 by 1.4mm, the module was developed by Murata and Altair and includes an ALT1250 chipset. It also provides GNSS functionality and is RoHS compliant to address consumer and industrial IoT applications.
"Flexible and optimised solutions are the building blocks for realising IoT on every wireless device," said Mehul Udani, director for Murata in the Americas. “With the AT&T certification, developers can easily tap Murata's RF expertise and access best-in-class solutions. Murata's type 1SC module is a significant asset as demand for more miniaturised, higher functioning solutions continues on its steep rise.”
Murata designs, manufactures and sells ceramic-based passive electronic components, communication modules and power supply modules. The company has employees and manufacturing facilities throughout the world.
"Murata is a world leader in providing innovative building blocks for the internet of things," said Ilan Reingold, vice president at Altair Semiconductor. “Murata's partnership with Altair reaffirms the quality of our products and our performance leadership in cellular IoT. The ALT1250 is shipping in volume, allowing device makers to reimagine what is possible in terms of power consumption, performance and overall quality."
Altair Semiconductor, a Sony Group company, provides cellular IoT chipsets. It partners with global vendors, including Giesecke+Devrient, Here Technologies, Murata, Sierra Wireless and WNC, to provide low-power and cost-efficient modules for industrial and consumer IoT applications such as trackers, smart meters, wearables and vehicle telematics. Altair's chipsets have been commercially deployed on LTE networks, including by AT&T, China Mobile, KDDI, Softbank, Verizon and Vodafone.
