Wireless systems are becoming increasingly
popular for conference centers and seminar
hotels. Unlike open-air events and large-scale
performance facilities, the main focus here is
not on coverage or the optimal utilization of as
many channels as possible, but maximum fle-
xibility.
Several events taking place at the same time,
adaptable sizes of seminar rooms, and a high
level of reliability, combined with maximum
mobility of lecturers – these are the essential
parameters that need to be considered when
planning wireless systems for seminar centers.
The example of a typical seminar hotel can
demonstrate the large variety of options avail-
able to organizers with a well-designed 8-chan-
nel system.
Optimum room coverage via high-performance
antennas and diversity reception for preventing
dead spots are the key prerequisites. Anything
from one to eight channels must be available
for three structurally separated rooms, one of
which can be divided by a variable partition.
Optimum RF coverage of each room is ensured
by one pair of booster antennas per room and
two pairs in the variable room.
This arrangement maintains full diversity func-
tionality even if the room is partitioned. The
various antenna cables from the seminar rooms
are joined together by antenna combiners and
the signals distributed to the receivers via
antenna splitters. Where longer cable runs are
needed, additional antenna boosters are inte-
grated into the line.
To save space, the wireless system can be
mounted in a rack or placed in a separate
equipment room. This unobtrusive installation
will not impair the effect of the interior decora-
tion.

Seminars
At seminars and lectures held in relatively small rooms,
care must be taken to identify possible dead spots that
can occur despite the short distances. Furniture, people,
lots of electronic devices (luminescent tubes!), curtains,
blinds etc. can cause wireless systems to fail even in con-
fined spaces. We recommend using a true diversity system
in conjunction with high-performance antennas.
