Development of the u-blox SARA-N2, an optimized narrowband (NB) IoT module.

u-blox announced plans to launch the SARA-N2 NB-IoT (Narrowband IoT) module, the world's first wireless communication module compliant with Release 13 and Narrowband IoT (LTE Cat. NB1), the standards set by 3GPP, the global mobile communications standardization technology cooperation organization.

Designed for applications such as smart buildings and smart cities, facility metering, white goods, asset tracking, and agricultural and environmental monitoring, this module is powered by a single-cell battery and can operate for 10 to 20 years.

The module, which features u-blox's cellular nested architecture and comes in a 16 mm x 26 mm LGA form factor, is easily upgraded from u-blox GSM, HSPA or CDMA modules, ensuring seamless mobility across technologies.



The SARA-N2 module provides secure communications with guaranteed service quality in existing bands. It also supports downlink speeds of up to 227 kbps and uplink speeds of up to 21 kbps. Because it supports three RF bands simultaneously, the same module can be used in most areas.

Unlike other wireless communication technologies, NB-IoT has the advantage of less complex devices, ultra-low power operation, and the ability to support up to 150,000 devices per single cellular cell. Above all, this technology improves coverage, providing superior performance even in vulnerable communication conditions such as underground or inside buildings.

Compared to low-power wide area (LPWA) solutions that operate in unlicensed bands, NB-IoT offers superior security and freedom from interference because it uses a licensed spectrum-based network. Other advantages include its point-to-point network architecture, which reduces latency compared to mesh networks; its need for only 200 kHz of bandwidth allows it to operate alongside existing 2G and LTE networks; and its higher transmit power improves reliability and range.

Because it also enables robust two-way communication, features like firmware upgrades can be implemented wirelessly. Furthermore, NB-IoT enables global roaming, which is not possible with unlicensed spectrum-based technologies.

Stefano Moioli, Director Product Management Cellular at u-blox, said: “u-blox is a leader in NB-IoT. We are working closely with companies such as Vodafone, Deutsche Telekom and Huawei to successfully complete the first commercial trials of pre-standard NB-IoT technology in smart metering and parking applications.

These trials have demonstrated that NB-IoT networks operate much more efficiently than GPRS, and these advantages confirm the future potential of this technology. “We are very pleased to be able to announce the world’s first fully 3GPP-compliant module, enabling customers to take full advantage of existing technologies,” he said.

SARA-N2 NB-IoT module samples are expected to be available in Q4/Q4 2016, with mass production planned for early 2017.
