  The amount of data produced by highly granular silicon tracking detectors in
high energy physics experiments poses a major challenge to readout systems. At
high collision rates, e.g. at LHC experiments, only a small fraction of data
can be read out with currently used technologies. To cope with the requirements
of future or upgraded experiments new data transfer techniques are required
which offer high data rates at low power and low material budget. Wireless
technologies operating in the 60 GHz band or at higher frequencies offer high
data rates and are thus a promising upcoming alternative to conventional data
transmission via electrical cables or optical fibers. Using wireless
technology, the amount of cables and connectors in detectors can be
significantly reduced. Tracking detectors profit most from a reduced material
budget as fewer secondary particle interactions (multiple Coulomb scattering,
energy loss, etc.) improve the tracking performance in general. We present
feasibility studies regarding the integration of the wireless technology at 60
GHz into a silicon tracking detector. Spare silicon strip modules of the ATLAS
experiment are measured to be opaque in the 60 GHz range. The reduction of
cross talk between links is studied. An estimate of the maximum achievable link
density is given. It is shown that wireless links can be placed as close as 2
cm next to each other for a layer distance of 10 cm by exploiting one or
several of the following measures: highly directive antennas, absorbers, linear
polarization and frequency channeling. Combining these measures, a data rate
area density of up to 11 Tb/(s $\cdot$ m$^2$) seems feasible. In addition, two
types of silicon sensors are tested under mm-wave irradiation . No
deterioration of the performance of both prototypes is observed.
