The SARA-N2 Narrowband IoT (NB-IoT) module is one of the first cellular radio modules 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 between 10 and 20 years from a single-cell primary battery. It measures 16 mm x 26 mm and uses the u-blox nested architecture.
The SARA-N2 module provides secure, private communications over licensed spectrum with guaranteed quality of service. It supports peak downlink rates of up to 227 kbps and uplink rates of up to 21 kbps. Simultaneous support for three RF bands means that the same module may be used in most geographic regions.
The benefits of NB-IoT over other cellular radio technologies include lower device complexity, ultra-low power operation and support for up to 150,000 devices per single cellular cell. Most significantly, the technology offers a 20 dB link budget improvement over GPRS to give excellent performance under poor coverage conditions such as underground or inside buildings.
