U-Blox has introduced a 2G cellular module for M2M applications, such as utility metering and tracking systems.
The Sara-G450 quad-band GSM and GPRS module lets product developers migrate their products to 3G, LTE or LPWA technology to meet a broad range of environmental and technological requirements.
Cellular 2G technology provides reliable performance for mobile applications and broad geographical coverage. Until recently this made it the technology of choice for machine type connectivity such as fleet management, metering and tracking. While some regions are phasing out their 2G network infrastructure, most notably the USA, 2G continues to be a viable and popular option for M2M in regions still lacking NB-IoT and LTE Cat M1 networks or where coverage is spotty. The Sara-G450 is targeted at these markets.
Thanks to its pin-compatibility with the entire U-Blox cellular line-up, product designers can use a single platform and PCB design to enable a variety of air interface technologies, including 2G, 3G, LPWA (LTE Cat M1 and NB1), and high speed LTE. This also means product developers can anticipate future upgrades of their applications to move to LTE Cat M1 and NB1 connectivity as soon as they become available in their target markets.
The module is power-optimised for IoT applications. It has the flexibility to combine with a variety of GNSS or Bluetooth modules that integrate positioning, short range and cellular communication. An embedded internet suite facilitates the development of a wide range of M2M devices.
“2G technology continues to play a vital role in a broad range of geographical and industrial markets and will continue to do so for years to come,” said Rado Sustersic, senior product manager at Swiss firm U-Blox. “With the Sara-G450, we are offering a cost-effective module that addresses the demands of these markets while offering a clear upgrade path to LPWA technologies once they roll out.”
Samples will be available at the end of August with production starting end of September.
