As component cost fluctuations and product lifecycle management receive increasing attention, supply continuity, network longevity, and long-term investment considerations have become critical factors for IoT customers when selecting connectivity solutions.
For devices requiring long-term mass production, a proven connectivity solution not only ensures stable supply but also helps reduce repeated investments in hardware redesign, testing, and certification.
Fibocom’s LTE Cat.4 module NL668 has been in mass production since 2018 and has served hundreds of customers worldwide. The module continues to support stable production and reliable delivery, helping global customers deploy new projects while providing a proven option for connectivity solution migration and upgrades.
For communication modules with long production lifecycles, customers care not only about how long a product has been available, but also whether network infrastructure can continue to support deployment requirements and whether connectivity capabilities remain aligned with application needs.
While global mobile network sunset efforts are currently mainly focused on 2G and 3G networks, 4G LTE continues to support a large number of IoT connections and works alongside 5G to address different connectivity requirements.
For low-data-rate and cost-sensitive devices, Cat.1 bis provides an optimized connectivity option. However, for applications requiring higher data throughput, such as multi-channel video and image transmission, industrial routers, large file downloads, and OTA upgrades, Cat.4 remains well suited with its higher uplink and downlink capabilities.
In connected vehicle scenarios involving multiple concurrent services, connectivity stability and long-term supply capability of proven platforms remain key factors in solution selection.
Based on the Snapdragon™ X5 LTE modem (9x07), NL668 supports up to 150Mbps downlink and 50Mbps uplink, providing proven connectivity capabilities for high-data-volume applications and multi-service deployments.
NL668 has served hundreds of customers across industries including smart retail, low-altitude applications, intelligent transportation, industrial IoT, and AI robotics.
In vehicle T-Box applications, NL668 supports vehicle data transmission, remote control, and OTA updates. In AI companion robots, NL668 enables connectivity between devices and cloud-based AI models, supporting status reporting and remote upgrades.
Behind its continued stable shipments is the ongoing validation of NL668’s hardware and software capabilities, network adaptation, and large-scale delivery capabilities across diverse customer projects.
To address different regional requirements in frequency bands, operator networks, and certification standards, NL668 provides regional variants for markets including China, North America, Europe, Australia, and Southeast Asia.
Based on the same proven architecture, customers can efficiently adapt the module to different target markets, reducing repeated development, testing, and certification efforts while lowering the cost of multi-region product deployment.
Liu Sunzhi, General Manager of MTC BU at Fibocom, said:
“Communication modules ultimately serve customers’ long-term business operations. Whether a product can remain relevant throughout market cycles depends not only on technical specifications, but also on its ability to continuously address real-world requirements, protect customers’ existing investments, and support global deployment. The commercial success of NL668 represents not only market validation of a single product, but also reflects Fibocom’s long-term product capabilities, supply chain resilience, and global service capabilities.”
Since entering mass production in 2018, NL668 has demonstrated that long-term product maturity is not about relying on legacy solutions, but about continuing to meet evolving market demands after years of real-world validation.
