Is NB-IoT losing its edge? Why operators are turning to LTE, 5G and satellite for 2025 (Reader Forum) – RCR Wireless News

In the early days, Narrowband IoT (NB-IoT) was touted as the ultimate low-cost, low-power solution that would upend the IoT connectivity market for good. Offering reliable indoor coverage and minimal power consumption, it promised massive-scale deployments across essential products such as smart meters, environmental sensors and asset-tracking devices — critical for a developing technological world. Yet, NB-IoT’s rapid decline in popularity, coupled with the operator pivot toward LTE, 5G and satellite connectivity, has spotlighted significant challenges for Narrowband IoT — an issue that has predominantly overshadowed its once sky-high potential.
In the beginning, NB-IoT had emerged as the ultimate “game-changer” for devices whose prime purpose was in sending small amounts of data. It boasted extended battery life and quick integration into any existing cellular infrastructure. It was hailed as cost-effective with broad coverage and was seen to be ideally suited to the IoT demands of dense urban areas and remote environments.
Yet, while markets like China aggressively and successfully adopted NB-IoT, its uptake globally quickly stagnated. According to Eseye’s 2025 IoT & Telecom Predictions — a global review of IoT trends — it has become clear most Mobile Network Operators (MNOs) are keen to sidestep NB-IoT in favour of more robust solutions for the future.
It would have been a challenge for businesses if they had persevered with the shortcomings of NB-IoT. So, instead of attempting to wrestle with its limitations, operators are now gravitating to LTE, 5G and satellite connectivity, each offering some clear advantages over NB-IoT:
The key takeaway from all the technical innovations in IoT is that economic viability remains the linchpin of success. Many MNOs found NB-IoT’s high overhead and patchy global presence less than convincing. Even the most technically sound protocol needs a completely sustainable, ROI-friendly model—or face a swift exit from widespread adoption.
It is clear we are seeing the connectivity landscape evolving around multi-operator eSIM orchestration and cloud-based SaaS platforms; all capable of coordinating LTE, 5G and satellite links seamlessly. It is an approach that offers MNOs the versatility to meet enterprise customers’ global coverage demands thus solving the traditional in-country roaming woes that have dogged NB-IoT for far too long.
By minimising integration friction and providing near 100% connectivity across more than 800 networks, these next-gen solutions maintain the agility operators need to stay competitive in a market that demands — above all else — robust reliability, meaning consistent and dependable service and cost-effectiveness, meaning the ability to deliver value for money.
NB-IoT’s decline has truly underscored one vital lesson for IoT stakeholders and that is innovation alone isn’t enough. If a technology isn’t able to achieve scalability and profitability, then operators will inevitably turn to more flexible, resilient and future-ready alternatives as we have seen with the shift to LTE, 5G and satellite connectivity for the future.
