Quick Answer
LTE450, NB-IoT and LoRaWAN address different segments of the IoT connectivity landscape. LTE450 is a full-featured private cellular network with guaranteed QoS and high throughput. NB-IoT is a low-power, low-bandwidth cellular IoT technology on public networks. LoRaWAN is an unlicensed sub-GHz IoT protocol with very low power consumption but limited throughput and no guaranteed QoS. For critical utility infrastructure, LTE450 is the appropriate choice; for low-power sensor monitoring, NB-IoT or LoRaWAN may be more cost-effective.
Technology Comparison
| Criteria | LTE450 | NB-IoT | LoRaWAN |
|---|---|---|---|
| Spectrum | Licensed private | Licensed (public MNO) | Unlicensed (ISM) |
| Throughput | 15-30 Mbps/cell | 20-250 kbps/device | 0.3-50 kbps/device |
| Latency | 40-100 ms | 1.6-10 s | 1-5 s (+ duty cycle) |
| Security | 3GPP AKA + SIM | 3GPP AKA + SIM | AES-128 (no MNO cert) |
| QoS guarantee | Yes (private EPC) | No (shared public) | No (best effort) |
| Battery life | Years (LTE-M) | 10+ years | 10+ years |
| Coverage | Dedicated, optimised | Public MNO coverage | Operator/self-deployed |
| Firmware OTA | Yes (full bandwidth) | Yes (slow) | Limited (SF/duty cycle) |
| Cost per device | Medium (module cost) | Low | Low |
When to Use Each Technology
LTE450: Mission-critical communications (SCADA, protection relaying, real-time control), high-throughput requirements (video surveillance, large data files), applications requiring guaranteed QoS, private network with security isolation requirements, or any application where public network availability is insufficient. The natural choice for electricity DSOs, water companies, and gas network operators with substantial infrastructure communication needs.
NB-IoT: Low-power sensors reporting infrequently (temperature, pressure, fill levels), battery-operated devices in public LTE coverage areas, applications tolerating several seconds of latency, and where volume economics make per-device cost minimisation critical. Good for agricultural IoT, parking sensors, waste monitoring, and non-critical environmental monitoring.
LoRaWAN: Ultra-low-power devices in areas without public cellular coverage, very low data rate applications (sub-100 bytes per hour), and applications that can self-deploy a gateway network. Well-suited to agricultural sensor networks, heritage building monitoring, and industrial asset tracking.
Frequently Asked Questions
LTE450 can serve all the IoT applications that LoRaWAN serves, and more, but at higher cost per device and higher power consumption (unless LTE-M power saving modes are used). For applications currently served by LoRaWAN that need improved security, guaranteed QoS, or are migrating to a private cellular network for other reasons, LTE-M on LTE450 is a viable upgrade path. However, if existing LoRaWAN deployments are meeting requirements at lower cost, replacement is not automatically warranted.
5G RedCap (Reduced Capability NR) is an emerging technology designed to address the IoT gap between NB-IoT/LTE-M and full 5G NR. However, in 2025 5G RedCap is in early commercial deployment and chipset/device availability is limited. LTE450 is mature technology with wide chipset support, certified devices, and operational networks. For deployments today, LTE450 is the practical choice. The question of future evolution is covered on the LTE450 vs 5G RedCap page.
