Instant connectivity for your products

How do you connect your product?

WiFi was,
Cellular is.

With our Narrowband+ offering, you can connect your product easier than ever: via cellular. Forget about gateways, complicated setup procedures or complex integrations into your network.

Narrowband+ offers instant connectivity for your products.

Your benefits


Deep Coverage

Up to 20 dB better coverage than with LTE Advanced and can therefore also be used in remote locations, such as basements or underground garages.


Long battery and life (up to ten years!) due to reduced data consumption and more efficient transfer rates.


Reduce expenses and gain efficiency with affordable implementation thanks to low costs per component.



Remote Monitoring

Remote monitoring allows you to understand your products, how they are behaving, how they are being used, and what problems they are experiencing. Devices send telemetry data over Narrowband+, which is then transferred directly into your existing IT solutions for further processing.

Remote Configuration

Save money by flexibly adjusting product parameters and settings remotely without having to send out a technician. Receive all necessary product parameters and options directly in your existing IT solutions.

Over-the-Air Updates

Wirelessly upload functionalities, bug fixes or security updates directly to your products in the application field via the over-the-air technology.


Operated and secured by grandcentrix specialists, Narrowband+ gives you the ability to support millions of devices and scale flexibly. This is made possible, among other things, by operation via Azure and integration into the global Vodafone Connectivity Platform.
