Dense Reader Mode

(abbreviated DRM) is a function for optimizing communication between readers and transponders in an environment in which several readers are used at the same time (high reader density). To prevent mutual interference between the devices, the DRM assigns free transmission channels in a predefined frequency spectrum to each reader. This enables a more efficient use of the bandwidth, an improvement in reading performance and a reduction in potential interference.
