Mobile Data Memory - MDS U313
A&D SE PS 3, R. Völler
Description
The MDS U313 is a mobile data memory of the MOBY U long-range identification system. With a storage capacity of 2 Kbytes, it is designed for use in transportation and logistics tasks. Very low power consumption ensures a long life of approx. 5 years. The extremely sturdy, interference-proof MDS can be
read and write-accessed at a distance of up to 3 m. The MDS U313 is addressed directly with byte memory accesses. With its transmission frequency in the ISM frequency band at 2.4 GHz, the MDS offers a
very high net data transmission speed of approx. 8 Kbytes per second without multitagging and approx. 4
Kbytes per second even with multitagging and two MDSs.

Safe for pacemakers
1)
The lifespan depends on several factors - the temperature, the time the MDS remains in the antenna
field of the SLG (zones 1 and 2) and the amount of data read/written.
