T-Mobile has certified U-Blox’s LTE Cat NB1 Sara-N410 module to run on its NB-IoT network, the first NB-IoT network to launch in the USA.
At 16 by 26mm, Sara-N410 supports low power consumption, making it suitable for cost optimised long-term deployments required by many IoT applications. These 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.
Firmware updates can be delivered securely with the Swiss company’s proprietary uFota (firmware over the air) client-server offering that uses LWM2M, a light and compact protocol for IoT applications. This lets users maintain the hardware over the full lifetime of the product for future enhancements to features and functionalities, especially in the case of applications running on devices deployed over long periods of time.
The module also supports non-IP data delivery, a more efficient way of transmitting data for throughput-constrained low power wide area (LPWA) technologies.
The module’s nested design provides 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 and e-DRX extended discontinuous reception, which can extend battery lifetime up to ten years.
The 3GPP coverage enhancement lets the module’s connectivity reach deeper into buildings and even underground when compared with 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 recognised standard with extended coverage and low power consumption,” said Patty Felts, principal product manager at U-Blox.
U-Blox has announced that its Nina-B3 series are qualified for all Bluetooth 5 features including long range. The wireless MCU module brings access to U-Blox’s connectivity software.
