The new low power cellular IoT for NB-IoT networks is launched by Sony.

The Altair ALT1255 new low-power NB2 chipset was launched by Sony Semiconductor Israel (Sony), a leading cellular IoT Chipset provider. The ALT1255 is a 5G-ready, rich application layer, designed with an integrated SIM (iSIM), user MCU, and GSM/GPRS fallback modem.


ALT1255 allows device manufacturers to develop low-power, cost-sensitive, globally interconnected devices for the monitoring, management, and control of critical facilities, medical devices, logistical trackers, and a variety of LPWA applications.

The ALT1255 framework is now open for the company and chosen by the key players of the module.


Sony Semiconductor Israel, which uses LTE-M/NB ALT1250 chipsets, developed the ALT1255 internally and utilizes its fully mature, generally recognized, and worldwide accredited NB/2G technology. The chips are packed with applications, application modems, and networking layers, and APIs to quickly and easily connect with the Altair product family.

"A feature-rich, fully integrated 2G fallback NB-IoT cellular chipset is increasingly needed," said Dima Feldman, Sony Semiconductor Israel VP for Product Management and Marketing. "The modular designs based on the ALT1255 will provide the smart meters, logistics, telematics and city applications with reliable connectivity."

The integrated iSIM ALT1255 removes the cost, size, and power barriers, and adds an additional security layer. The GSM/GPRS modem fills the gaps in LPWA network coverage and enables forward-looking technological deployment in mixed 2G/NB countries. In addition, ALT1255 incorporates a low-power ARM Cortex-M4 MCU, completely isolated from the modem hardware and built to operate a range of IoT and sensing applications, as well as an adaptation layer to interconnect within the current ecosystem.

The solution offers safe cloud access outside of the box through a variety of industry-accepted communication protocols such as COAP and LWM2M.


As part of the Sony Altair Product Family, ALT1255 has gained broad support from carriers, iSIM community partners, and developers who build IoT products. The chipset is certified by the GCF, which enables customers to speed up module and device certification.
