Installation & Operation
3.1 Notes on installation
Reflections and interferences
The antenna fields are weakened by absorbing materials and reflected by conducting
materials. When electromagnetic fields are reflected or there are other radio sources, this will
result in interferences. These circumstances will result in incorrect measurements; however,
these can be largely detected and corrected with the appropriate software (e.g. SIMATIC RTLS
Locating Manager). We still recommend that you prevent these influences. Especially objects
that cannot be penetrated by radio waves can cause localization errors.
Note
Metal surfaces reflect radio waves more than any other types of surfaces. Water, on the other
hand, attenuates radio waves. You should therefore evaluate your working environment and
integration for these influences.
Coexistence and de-sensing
To prevent interfering with each other, radio applications will use different frequency
bands. Use of these frequency bands is subject to state regulation. Because a frequency range
is considered a finite good, technologies were developed over the years that enable a
coexistence of different radio applications in the same frequency band. These technologies
are also used by SIMATIC RTLS. However, interferences can still be caused by other radio
devices. Arrangements are being made here, too, so that these interferences do not impact
the operation of the RTLS localization system. To keep interferences to a minimum, the RTLS
infrastructure components must not be installed in the close vicinity of other radio
applications. Strong senders in close vicinity can interfere with the reception, even when they
are located in neighboring frequency bands (de-sensing). This is true, for example, for the
2.4 GHz ISM band and PULSE in the UWB channel 5.
Assembling the transponder prior to starting up
Proceed as follows to assemble the transponder prior to starting up:
1. Insert the battery in the battery compartment according to the polarity direction.
2. Close the enclosure by first placing the top part into the bottom enclosure and letting it
engage on the bottom.
Remove the battery before returning the transponder
Remove the battery before returning the transponder. Batteries must not be returned.
