Different applications with specific properties require a weighing-up of priorities such as energy consumption versus latency of data transfer or the selection of the frequency band with regard to security, fault and data rate points of view. In the design of a self-organized sensor network the determination of the requirements, which the application imposes, is therefore very important. The engineers at Fraunhofer IIS support you here with their knowledge and experience.

In each new project we run through a requirement and design phase with our customers. In doing so we guarantee you exactly the solution you require.

After setting your priorities, we draft the solution idea with you and work on a solution design:

  • Determination of protocol parameters
  • Analysis of data quantity, data back-up, aggregation / filtering
  • Energy concept / estimates
  • Integration concept
  • Interworking with other radio systems
  • Control concept
  • ID and address concept
  • Software architecture
  • Concepts for update / maintenance / monitoring of the modules in operation
  • Definition of the hardware platforms
  • Interfaces / drivers
  • Radio measurements in the target environment
  • Estimation of the outlay for realization of the project, with time scale
  • Allocation of responsibilities

 

Licensing of the s-net® Protocol Development Kit

In order to do justice to the various applications, the communication software must be able to be adjusted flexibly to meet the various requirements. Our s-net® protocol technology is designed for this thanks to its modular software architecture. Alongside standard solutions, primarily individual customer software packages are compiled.

For an individual protocol compilation and/or expansion, we clarify the exact requirements for the system functionality and create a system concept with our customers. Fraunhofer IIS implements the system functionality and takes care for extensive system tests and the documentation of the methods. Furthermore we offer support for the commissioning, release management, transition workshops and training courses.

 

Licensing of the Hardware Reference Design

All hardware designed by Fraunhofer IIS for wireless sensor networks can be licensed for the customer‘s own product development. The modules can either be produced unchanged, or the design documents can be the starting point for your individual solution.

When licensing a reference design, you will receive as part of your license package:

  • a PDF file of the schematic
  • a bill of materials in XLS format, specifying components and manufacturers
  • a Gerber file of the PCB layout
  • available documentation such as the data sheet, pin configuration and ratings
  • if available: test reports on compliance of the sensor node with the EN 300 220 V2 and EN 301 489 standards

We will be glad to discuss with you the terms of your individual license for using one of our reference designs. For more information send an e-mail.

 

Development

With our s-net® protocol development kit and hardware reference design we provide you with the basis for solutions which can be customized according to your wishes. It forms the foundation for the realization of large-scale and long life wireless sensor networks. As Fraunhofer IIS has finished part-technologies, we can provide you with a quick prototype development.

 

Supplementary Technology Offer

If batteries are not sufficient, or if you would simply prefer not to use these, the extremely energy-saving s-net® technology can also draw the required energy by means of energy harvesting solutions from the environment, e.g. from differences in temperature or vibrations. Fraunhofer IIS supplies individual components for this, such as finished or adjustable comprehensive systems for the system or device integration.

For special fields of application, sensor nodes with our patented wake-up receiver technology are available.
