Secure & reliable data transmission

Without functioning connectivity, there is no functioning IoT solution. Secure data transfer is only guaranteed with 100% reliable data transmission: from machines, devices and objects networked via M2M communication via mobile communications technology into the cloud.

We organize all elements within the Wireless Internet of Things: M2M (Machine To Machine) technology, SIM card management, rates, wireless technology (Narrowband NB-IoT, LTE Cat M1, GPRS, GSM, UMTS, LTE, 5G) and data transmission.

Wireless technologies

Security, frequency, speed

The right wireless technology for your IoT project: security, speed and frequency – we master the most important parameters for optimal data transfer.

We use NarrowBand IoT for efficient networking of many end devices: the latest mobile communications technology, based on Low Power Wide Area (LPWA) and highly standardized by 3GPP. NB-IoT transmits at 200kHz and is ideal for smaller data volumes. Advantages: Reception even in shielded areas, deep building penetration, low cost, extremely secure, high energy efficiency, low power consumption, easy installation. If required, we also use the transmission standards: LTE Cat M1, GPRS, GSM, UMTS, LTE, 5G.

SIM card management

Complete service from a single source

Data transmission via mobile communications technology involves many SIM cards in every IoT project. We take over the complete SIM card management including billing.


Our logistics service ranges from storage, quality and quantity control, picking, packaging, delivery and returns processing to reporting. SIM card management processes ensure reliable implementation: Interface analysis, support, ticket systems and continuous optimization of ongoing operations. In addition, there is seamless tracking of all serial numbers, including serial number validation, SIM card activation, and card replacement if required.


The right choice for every project scenario

With our network, we find the perfect rate for your IoT user scenario: We have been working closely with all network operators for decades. And we know exactly which tariff from which provider is best suited and most favorable for which IoT solution.


Our market position allows us to be completely independent of network operators, which means we can offer our customers top conditions. With the introduction of the new 5G generation of mobile communications technology, we are also taking advantage of national roaming: switching between national mobile networks depending on the strength of reception will then enable the best possible network coverage.

Secure data transmission

Safety First for Sensitive Data

Essential for the implementation of your IoT project: globally functioning machine-to-machine (M2M) communication. For reliable transmission of the collected data, we rely on the absolutely secure transmission medium of mobile communications. We establish a connection that cannot be attacked via the established networks.


We use the established transmission standards GSM and UMTS, as well as LTE on request. The transmission of machine and sensor data is encrypted via standardized and proven transmission protocols with a sophisticated security concept – depending on the project via MQTT or AMQP. Secure connection to the IoT cloud or our customers’ servers is also guaranteed.

Sensor Interface

The IoT Gateway System

Especially for IoT applications, we have developed a sensor interface that functions as an IoT gateway system via battery or continuously operated. The communication with the cloud runs via an integrated modem equipped with an M2M SIM card. With its IP65-rated rugged housing, it serves as a gateway for any type of sensors in industrial environments.


Equipped with a wide range of sensors and connections to various bus systems, the interface can send virtually any type of information to the cloud service. Security was particularly important to us here: communication with the cloud is validated via several unique identifiers.
