MQTT is a "rediscovered" communication/messaging protocol. Although the protocol was developed in its original form back in 1999, it has been experiencing a real boom in recent years, particularly due to current developments in the IoT sector. It enables millions of clients (devices or applications) to communicate with each other efficiently and is designed to work particularly well in environments where a reliable network infrastructure or reliable devices cannot be expected. Billions of messages can be exchanged efficiently via a central element, the so-called broker. The protocol can therefore be described without exaggeration as one of the most important protocols for the IoT, but is not limited to IoT applications. This course covers the protocol itself, its special features and existing products in detail.

Classroom training
- Do you prefer the classic training method? A course in one of our Training Centers, with a competent trainer and the direct exchange between all course participants? Then you should book one of our classroom training dates!
-
Hybrid training
- Hybrid training means that online participants can additionally attend a classroom course. The dynamics of a real seminar are maintained, and the online participants are able to benefit from that. Online participants of a hybrid course use a collaboration platform, such as WebEx Training Center or Saba Meeting. To do this, a PC with browser and Internet access is required, as well as a headset and ideally a Web cam. In the seminar room, we use specially developed and customized audio- and video-technologies. This makes sure that the communication between all persons involved works in a convenient and fault-free way.
-
Online training
- You wish to attend a course in online mode? We offer you online course dates for this course topic. To attend these seminars, you need to have a PC with Internet access (minimum data rate 1Mbps), a headset when working via VoIP and optionally a camera. For further information and technical recommendations, please refer to.
-
Tailor-made courses
-
You need a special course for your team? In addition to our standard offer, we will also support you in creating your customized courses, which precisely meet your individual demands. We will be glad to consult you and create an individual offer for you.
