2G cellular module offers an easy upgrade path to LPWA

July 31, 2018 // By Jean-Pierre Joosting
The u‑blox SARA-G450 is a cost-optimized 2G cellular module for machine-to-machine (M2M) applications, such as utility metering and tracking systems.

Provided in the industry-proven SARA form factor, the SARA‑G450 quad-band GSM/GPRS module lets product developers easily migrate their products to 3G, LTE, or LPWA technology to meet a broad range of environmental and technological requirements.

2G cellular technology offers 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 currently 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 ideal for cost and space-sensitive applications in 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 systems for a variety of air interface technologies, including  2G, 3G, LPWA (LTE Cat M1 and NB1), and high speed LTE. This also means that 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.
