IoT Networks for the Internet of Things
M2M One NZ, in partnership with Spark NZ, provides robust IoT network solutions. We ensure your devices stay connected reliably across New Zealand.
The Internet of Things (IoT) is transforming industries by empowering businesses to make data-driven decisions and enabling automation at an unprecedented scale.
Our networks leverage the latest advances in mobile technology. These include 5G, 4G/LTE, Cat-M1, and NB-IoT, providing comprehensive coverage for all types of IoT applications.
Connectivity Options for Every IoT Application
5G IoT Network
Experience Next-Level IoT with Spark’s 5G Network
The Spark 5G network brings a new era of connectivity to New Zealand. It operates primarily on the N78 frequency. The Spark 5G network uses Non-Stand-Alone (NSA) technology. This means devices must connect to 4G LTE before accessing 5G.
- Greater stability and seamless transitions between 4G and 5G.
- IoT devices should support LTE 2100MHz (B1) and 5G (N78).
- Increased speeds, lower latency, and massive IoT deployment support.
5G offers the performance needed for advanced IoT solutions, such as autonomous vehicles, smart cities, and remote health monitoring systems.
4G/LTE Network
Reliable and Widely Available Coverage
Spark’s 4G/LTE network offers nationwide coverage. It supports multiple frequencies, providing flexible options for IoT devices.
- Essential Frequencies: LTE 2100MHz (B1), LTE 700MHz (B28), LTE 1800MHz (B3)
- Enhanced Performance Frequencies: LTE 2300MHz (B40), LTE 2600MHz (B7)
- Reliable Coverage: Maintains connectivity even in remote or challenging environments
The combination of these frequencies means that M2M One NZ can offer reliable connectivity for a diverse range of IoT applications, including asset tracking, environmental monitoring, and smart agriculture.
3G Network
Legacy IoT Devices
Many IoT applications are shifting towards 4G, Cat-M1, and 5G. However, Spark’s 3G network still plays a role in supporting legacy IoT devices. It operates on 3G 850MHz (Band 5) and 3G 2100MHz (Band 1).
- Supports devices that do not yet support newer network technologies.
- Provides ongoing coverage for legacy devices.
- Encourages transition to 4G/LTE or Cat-M1/NB-IoT for better performance.
As the telecom landscape evolves, transitioning from 3G to advanced options helps future-proof IoT solutions and ensures better network longevity.
- The Spark 3G network will be shutting down towards the end of 2025.
- We recommend upgrading devices to ensure continued connectivity.
- Transitioning to 4G, 5G, and Cat-M1/NB-IoT technologies will provide improved performance and longevity.
Cat-M1 (LTE-M) Network
Enhanced Connectivity for IoT Devices
Cat-M1 (LTE-M) is a key technology for IoT devices. It provides a reliable medium for low to moderate data rate applications. Cat-M1 also maintains power efficiency.
- Operates on LTE 700MHz (Band 28) and LTE 1800MHz (Band 3).
- Ideal for asset tracking, smart meters, and healthcare monitoring.
- Ensures consistent and secure IoT deployments across New Zealand using Spark’s extensive 4G infrastructure.
NB-IoT (Narrowband IoT) Network
Designed for Low Data Rate, Low Power Applications
Narrowband IoT (NB-IoT) is another key offering from Spark’s IoT network solutions. It operates on LTE 700MHz (Band 28) and LTE 1800MHz (Band 3). NB-IoT is optimized for ultra-low data rate applications. It is ideal for scenarios where power consumption is critical, such as smart agriculture sensors, environmental monitoring, and smart parking solutions.
- Reliable, energy-efficient connectivity for remote sensors.
- Supports devices staying active for years on a single battery.
- Suitable for large-scale IoT deployments across diverse environments.
2G/GSM Network
Spark does not operate a 2G/GSM network.
Future of IoT Networks in New Zealand
The future of IoT in New Zealand is promising. Ongoing advancements in network infrastructure are enabling greater capabilities for connected devices.
Spark NZ’s investments in expanding 5G coverage and enhancing the capabilities of 4G, Cat-M1, and NB-IoT networks ensure that businesses can confidently build and scale IoT solutions tailored to their needs. As these networks continue to evolve, M2M One NZ is committed to providing customers with the most reliable, future-ready connectivity solutions.
Additionally, the next generation of Satellite IoT and Non-Terrestrial Networks (NTN) is becoming available. These technologies promise even broader coverage, reaching areas previously inaccessible and opening new possibilities for IoT across New Zealand.
