u‑blox’s ultra-compact NB-IoT module SARA‑N410 is now certified for T‑Mobile’s new NB‑IoT network 

Narrowband IoT (NB-IoT) is a new way of communicating with “things” that require small amounts of data, over long periods, in hard to reach places. u-blox is helping to advance NB-IoT by collaborating with T‑Mobile US, the first operator to roll out a commercial NB‑IoT or LTE Cat NB1 network in the US. The company said that its multi‑mode SARA‑R410M‑02B module is now certified for use on T‑Mobile’s network.

At an ultra-compact 16 x 26 mm, SARA‑N410 supports ultra-low power consumption, which u-blox says, makes it ideal for cost optimized long‑term solutions required by many IoT applications. Those include utilities such as gas, water and electricity metering, smart cities for instance with street lighting, parking sensors and waste management, smart buildings with building automation, HVAC and access control, as well as industrial monitoring and control, the company said.

Critical firmware updates can be delivered securely with u‑blox proprietary uFOTA (firmware over the air) client/server solution that uses LWM2M, a light and compact protocol ideal for IoT applications. This enables customers to maintain the hardware over the full lifetime of the product for future enhancements to features and functionalities, especially in the case of crucial applications running on devices deployed over long periods of time.

Also, SARA‑N410 offers a nested design to provide easy migration between u‑blox 2G, 3G and 4G modules, while enabling future‑proof, seamless mechanical scalability across technologies.

With a temperature range of -40 to +85°C, the module supports Power Save Mode (PSM) and Extended Discontinuous Reception (e‑DRX), which can extend battery lifetime up to 10 years.

Notably, 3GPP Coverage Enhancement permits the module’s connectivity to reach deeper into buildings and even underground when compared to other air interface technologies such as GSM or Cat 1.

“The u‑blox SARA‑N410 is now certified for T‑Mobile’s new NB‑IoT network and thereby enhances u‑blox’s position as a leader in Narrowband IoT, a globally recognized standard with extended coverage and low power consumption,” said Patty Felts, Principal Product Manager, Product Center Cellular at u‑blox.
