These trials reflect u‑blox’s focus to meet pent-up demand for low power wide area (LPWA) connectivity, as delivered by NB1 technology, standardized by 3GPP in June 2016. The benefits of NB1 over other cellular radio technologies include lower device complexity, ultra‑low power operation, and support for more than 50,000 devices per single cellular cell. As it uses a licensed spectrum-based network, it also offers greater security and high robustness from interference. NB1 is therefore ideal for IoT and M2M applications requiring extremely low power consumption and better coverage even in shielded areas.
Keeping 2G network is not efficient use for the increasing number of IoT devices. NB-IoT is the natural evolutionary step for wireless operators, hardware manufacturers, and end customers,” says Ricardo Adulis at SmartCore, the representative of u-blox in Brazil. Embedded in the test device is the u-blox SARA‑N2 NB‑IoT module, the world’s first cellular NB-IoT module compliant to the 3GPP Release 13, Narrowband IoT (LTE Cat NB1) standard. Designed for use in applications such as smart buildings and cities, utilities metering, white goods, asset tracking, and agricultural and environmental monitoring, the module will operate for 10+years from a single‑cell primary battery. Its 16- x 26-mm LGA form factor, using u‑blox nested architecture, facilitates simple upgrades from u‑blox GSM, HSPA or CDMA modules and ensures future‑proof, seamless mechanical scalability across technologies.
“Allowing for easy migration across 2G, 3G and 4G, cellular modules from u‑blox support a comprehensive set of communication protocols with minimal signalling overhead to conserve power,” added Suresh Ram, President u-blox America. “We are working with our partners and customers to introduce products with our modules where longevity of operation and reachability in poor propagation conditions are mission critical.”
