u‑blox has launched what it claims the smallest LTE Cat M1/NB1 multimode module with global support for IoT and M2M applications. Measuring just 16 x 26 mm, the SARA‑R410M‑02B offers both LTE Cat M1 and Cat NB1 in a single hardware package, as well as software‑based configurability for all deployed bands.
The SARA‑R4 Series covers applications in many areas, such as gas / water / electricity metering, city street lighting, building automation, HVAC, industrial monitoring and control, telematics, insurance, asset & vehicle tracking, security systems, alarm panels, outpatient monitoring and many consumer wearables.
The benefit of the module is that it allows customers to use a single hardware version globally. This provides enormous efficiencies in logistics and SKU management. Customers can easily respond to changes in business or market conditions, since supported frequencies and operator configuration decisions can now be made at “zero hour” or even later in the field, explained u-blox.
In addition, users can even select modes dynamically between Cat M1and Cat NB1 as either single or preferred connection.
Critical firmware updates can be delivered with u‑blox proprietary uFOTA (firmware over the air) client/server solution that uses LWM2M, a light and compact protocol that is ideal for IoT applications.
This enables customers to continue using the same hardware for future enhancements to features, functionalities or operator certifications, making it well‑suited for crucial applications running on devices that may be deployed in the field over long periods of time.
Another benefit of SARA‑R410M‑02B is the hardware readiness for future support of voice functionality via VoLTE over Cat M1, which can be used for applications requiring a level of human interaction, as is the case for security applications such as alarm panels.
Migration to SARA‑R4 Series from other u‑blox 2G, 3G and 4G modules is made easy by the firm.
The module provides an extended temperature range of -40 to +85°C, and supports Power Save Mode (PSM) and Extended Discontinuous Reception (e‑DRX), which can extend battery lifetime up to 10 years, claims u-blox.
3GPP Coverage Enhancement permits the module’s connectivity to reach deeper into buildings and basements, and even underground when compared to other air interface technologies such as GSM or Cat 1.
