WIRELESS-COMMUNICATION SYSTEMS
Nowadays there is a need of a timely and reliable
exchange of important information and contents between people.
You need to speak… to listen at the same time and to
be of course clearly understandable! At this purpose
from long time Wisycom has been elaborating a
high-technology to project its wireless “Full-duplex
intercom” and “In Ear Monitoring & Talk-back” systems.
These systems are able to work with a medium-band
and narrow-band transmitting mode, and they have
been developed for professional applications in the
Broadcast, Theatres and Sound-reinforcements fields.
Wisycom high-technology, thanks to its long-experience,
allows to work without any noise, annoyance or trouble.

EXAMPLES OF BIDIRECTIONAL
BASE UNITS
FULL-DUPLEX BIDIRECTIONAL SYSTEMS
Thanks to its fully modular compositions, you can make up several
Base Units configurations.
As for the Unidirectional Systems, full-duplex systems can be mounted
either in Portable Minirack (with different widths, depending on the
required number of modules) and in standard 19”/1U or 19”/3U rackframes. The Base Unit can be one single-channel or multi-channel type.
The are available two types of Transmitters and Receiver Modules: in
a vertical-shape (3U height) and horizontal-shape (1U height).
Regarding the output power of the Transmitters, we are used to offer
units with an output power that can be factory pre-set in a value
between 10 mW (to comply the ETSI norms related to free-use Base
Units in UHF TV frequency range, is it a more than suitable power to
cover a big TV studio) and 300 mW (that allows a great operating
distance up to more than one mile). 2W Transmitter Module (in a vertical shape) is available for even longer distances.
The working frequencies can be set in two 7 MHz switching-windows
between 400 ÷ 550 MHz, with a minimum distance of about 10 MHz
between them.
The Transmitter and Receiver Modules are endowed with a balanced
and ground-isolated audio line connections. The audio input of the
Transmitter has a very great input-level adjustment capability, to allow
the easiest connection with all type of audio sources. The output level
of the Receiver Module is in the range of “line” value.

wireless-communication systems for the DVB-T scenario
• Both RX and TX links use the
same UHF band (400 ÷ 550
MHz), granting the maximum
frequency’s saving and the best
integration with other wirelesssystems. • All units present 16 RX and/or
16 TX switchable frequencies. • Narrow-band or medium-band
operation assures the maximum
flexibility of use and frequency’s
saving. • Suitable for very complex multichannel systems, thanks to the
extremely high RX intermodulation immunity and RF/IF selectivity and TX-signal clearness. WISYCOM
Here are some main examples:
A) All belt-pack transceivers receive
the same audio-signal from the basestation and transmit, one at the time by
PTT push-button, to the base. While
speaking, the transceiver operates in
full-duplex mode (it listens to and speaks at the same time).
Double-click pushing on on the PTT pushbutton, the transceiver starts to operate
in continuous transmitting (and receiving
at the same time) till the push-button is
pressed again.

• Fully modular architecture allows
the simplest building and even

wireless-inteercom system. • Exceptional sturdiness and absolute reliability. • Very great working-areas can be
easily covered by the connection
of more Base-units together, in
“master/slave”
architecture,
with synchronized frequencies
and diversity reception. systems modular architecture
Wisycom wireless-intercom systems
architecture is fully-modular. It is possible
and simple to build working systems in
different ways, depending on user’s
requirements. The systems can be
“custom” configured according to the
several needs of the operators.

• Superb audio quality and exceptional low-noise operations. • The Base Unit’s transmitter and
receiver modules are endowed
with audio connections lines,
which are balanced and isolated
by transformer. This assures the best and easiest
connection with any kind of
AF-sources, AF-loads and wired
intercom systems. • The automatic limiter on transmitter’s input prevents any
overload. • The working-frequencies can be
easy reprogrammed by PC.
The base-station is composed by the
following RF units:
• transmitters =n. 1
• receivers
=n. 1
Required frequencies (on base-station):
• transmitting =n. 1
• receiving
=n. 1
B)All belt-pack transceivers receive the
same audio-signal from the base-station
and can transmit at the same time (in
full-duplex mode) to the base.
The base-station is composed by the
following RF units:
•transmitters=n. 1
•receivers
=n. 1,
for each belt-pack transceiver used.
Required channels (on base-station):
•transmitting =n. 1
•receiving
=n. 1,
for each belt-pack transceiver used.
C) Each belt-pack transceiver receives a
separate audio-signal from the basestation and can transmit at the same
time to the base.
The base-station is composed by the
following RF units:
•transmitters=n. 1,
for each belt-pack transceiver used
• receivers
=n. 1,
for each belt-pack transceiver used.
Required channels (on base-station):
• transmitting =n. 1,

• receiving

Base-Unit in “master/slave” configuration
In some cases the coverage of the
“standard” base-station is not enough.
Therefore Wisycom has developed,
and tested for a long time, a special
technology to overcome this problem.
Wisycom offers the possibility to connect
together several Base-Units (in “master/
slave” configuration) to increase the
coverage area almost unlimited. In fact
the resulted total coverage area
is the sum of the single area of each
Base-Unit.
In order to grant excellent working
conditions immune from interferences,
Wisycom supplies special add-on boards,
to
upgrade
its
transmitterand receiver-modules to allow the
“master/slave” operations. So all transmitters can work in “iso-frequency”
mode and all receivers work in “remote
diversity” mode.
The “master” and “slave” Base-Units can
be installed far away one from the other
and they need to be connected together
by wire. Wisycom technology allows the
utilisation of simple balanced audio lines
or cheap telephone twisted-pairs (even
pre-existing) instead of expensive
dedicated coax or optical-fibres cables.
Thanks to Wisycom 25 years old experience in the field, the systems are
designed with the aim of granting not
only the actual maximum operating
quality of the products, but also their
maximum durability in time. This result
is reached with carefully sophisticated
technical solutions such as modularity
and the inter-changeability of the
various modules.
The best solution for system-engineers
are easily guaranteed by the combination of flexibility and modularity with
the highest quality standards.
