awiloc® Testbeds and Open Partner Consortium
© Fraunhofer IIS
awiloc® TestbedsBerlin, Hamburg, Munich, Nuremberg
awilocTM testsbeds push the development of location services in public areas (technology, services, applications)
The testbeds allow to test the operation under real conditions with all related aspects including deployment, accuracy, service concepts and user acceptance.
The testbeds are platforms for real-world applications and are also used for evaluation and enhancement of all related technologies and workflows.
Cooperation with online communities give application partners user feedback.

awiloc® TestbedsCommon Goals
The testbeds offer an operative platform for the positioning in buildings and inner cities. Enhancements to the city-wide locating technology can be realized in a real-world scenario.
Definition and exchange of APIs and data formats between partners speeds up development.
User acceptance and business cases can be evaluated in a real-world scenario.
