4. Confidea System
Information
4.1. General
System Architecture
4.1.1. Components
Confidea is a wireless conference system offering
conferencing facilities over a robust wireless link.
Depending on the model, these facilities include
discussion, voting and/or language distribution.
The delegate units are stand-alone, table top units
that wirelessly connect to the Confidea Wireless
Conferencing Access Point (WCAP). This Access Point
has a built-in web server that allows configuring and
monitoring of the system from any PC or laptop with
a network card, using a standard internet browser.
Depending on the application, Confidea can work as
a standalone system, but can also be connected to
an existing Televic TCS2500 or TCS5500 system.
4.1.2. Stand-alone system
A stand-alone Confidea system offers basic
discussion and basic voting or opinion polling
(depending on the model)
In this case there are no connections to other
systems, except for the Confidea WCAP that can
be connected to a LAN network for monitoring
and configuring.
The Confidea access point (WCAP) will in this
set-up act as a mini central unit, offering all
functionality for a basic discussion and/or
opinion polling application.
4.1.3. Connected to Televic wired
conference system
As part of a wired system, the Confidea offers
full functionality such as extended voting
facilities and language distribution. When
connected to a TCS2500 or TCS9000 central
unit, the Confidea set-up becomes an integral
part of the wired system

5.2. Televic Confidea
system
The wireless network of the Televic Confidea system
is based on the 802.11 a/g standards.
Additional protocols have been added on top of the
802.11 a/g standards to provide high robustness
against interference from other wireless devices.
These additional protocols also ensure a guaranteed
quality of service for the audio streams on the
wireless network.
The Confidea system supports the following
frequency bands (refer to Table 5.2):

In the 2.4 GHz ISM (Industrial Scientific Medical)
band, there are 13 overlapping wireless carriers
available. Only 3 non-overlapping carriers are
available.
In the “RLAN low” frequency band, there are 8 non-
overlapping wireless carriers. In Europe all of these
wireless carriers can be used. In the USA and Canada
(FCC regulations) only the 4 lowest wireless carriers
Note:
The 2.4GHz and 5GHz frequency bands
are license free world wide.
However you must be aware of country
specific limitations and follow them.

may be used (5180 MHz – 5200 MHz – 5220MHz –
5240MHz).
In the “RLAN high” frequency band, there are 10
non-overlapping carriers. In Europe all of these
wireless carriers can be used. In the USA and Canada
(FCC regulations) these frequencies cannot be used.
In the 5 GHz ISM frequency band, there are 4 non-
overlapping carriers. All of these carriers can be
used.
5.3. Frequency Planning
5.3.1. Use with WiFi base stations
nearby
When the CONFIDEA system is set to automatically
select the wireless carrier frequency, the COFIDEA
carrier frequency will be dynamically set to another
channel if other existing WiFi wireless devices occupy
the same channel. This dynamic frequency allocation
ensures a high robustness of the system even if the
frequency occupation changes during the meeting.
When the CONFIDEA system is set to manually select
the wireless carrier frequency, then you must make
sure the CONFIDEA wireless carrier does not overlap
the already occupied WiFi wireless carrier channels.
5.3.2. Use of multiple Confidea
systems
When the CONFIDEA system is set to automatically
select the wireless carrier frequency, the COFIDEA
carrier frequency will be dynamically set to another
channel if another CONFIDEA wireless system
occupies the same channel. This dynamic frequency
allocation ensures that each CONFIDEA system will
be set automatically to different frequencies.
When the CONFIDEA system is set to manually select
the wireless carrier frequency, you must make sure
the CONFIDEA wireless carriers of the different
rooms do not overlap each other.
Note:
The user can choose to set the wireless
carriers manually or let the CONFIDEA
system automatically select the best
wireless carrier frequency.

7.1. Introduction
The CONFIDEA-MICL and CONFIDEA-MICS pluggable
microphones are used with the different delegate-
and chairman units. These microphones have a uni-
directional response for optimum performance even
in noisy conditions. Both types have a very low
susceptibility to interference from mobile phones.

The system will decide the appropriate power setting
when the auto setting has been selected
Frequency
The drop down list box allows you to select the
frequency on which the system needs to operate.
Auto
When the ‘Auto’ setting has been selected, the
system will decide automatically on which frequency
to operate, based on its measurements of the
available spectrum. In this way, interference with
equipment that operates nearby is avoided.
Frequencies listed in BLACK color.
When one of the frequencies is selected out of the
list, the system will be forced to work on that
frequency and will not automatically switch to
another channel should interference occur.
Frequencies listed in BLUE color.
Some frequencies require a special procedure before
equipment can occupy the channel. These
frequencies are indicated with a blue color.
Compliancy with the ETSI EN301893 standard
requires a channel availability check on these special
frequencies before one of these frequencies can be
used.
This also implicates that, although an operating
frequency has been manually selected, the system
will still switch to another available channel when a
radar signal or other interfering signal has been
detected on that channel.
Frequencies listed in RED color.
Some frequencies will be marked in red indicating
that an interfering signal was detected on that
channel. The interference severity can be monitored
in the quality pages.

On this webpage the expected quality for each
possible RF channel in the 5 5.8 GHz ISM band can be
monitored.
This visualization of channel availability and quality
helps to select a fixed RF channel in case the system
is set not to work in automatic mode.
Note:
From time to time, the Confidea system
will also measure its own activity in the
channel on which it is currently
operating.
This results in a RED indication on the
corresponding bar graph, but does not
affect the reliable operation of the
system.
Note:
The channel availability is visualized using
colors:
A full GREEN bar indicates the
channel is available 100% of the
time. This channel is thus safe to use.
A full RED bar indicates the channel
is fully occupied by other radio
devices. This channel should not be
used to operate the Confidea system.
The more activity on a channel, the
more the corresponding bar will
color RED, and thus the more likely
interference will occur with other
systems.

12.3.1. General
Conference Configuration
Maximum Number of Active Microphones:
Defines the maximum number of simultaneous
active microphones. The system can handle a
maximum number of 8 active microphones.
Microphone Mode:
Defines the conference mode.
With Request:
Enables the participant to send a request to
speak to the chairman or conference operator
by pressing the microphone button (or to cancel
his request by pressing the microphone button
again). Once the floor is requested, the green
LED above the microphone button will flash. This
means that the conference unit is in request
mode.
The chairman or conference operator grants the
participant the permission to speak by using the
NEXT button or by clicking the green
microphone on the computer screen in case the
Confidea system is connected to a central unit
and PC control software is used.
While the conference unit is in request, the red
signal ring of the microphone will flash.
With Request No Clear:
Enables the participant to send a request to
speak to the conference operator or chairman.
However, he cannot cancel his request. The
chairman or conference operator grants the
participant the right to speak by using the NEXT
button or by clicking the green microphone on
the computer screen in case the Confidea
system is connected to a central unit and PC
control software is used.
While the conference unit is in request, the red
signal ring of the microphone will flash.
Direct Access:
Enables the participant his microphone to turn
on or off at any time. The only limitation here is
the maximum number of microphones which
may be active simultaneously.
FIFO:
In this conference mode, only one microphone
can be active at a time without intervention of
the conference operator. Activation of another
microphone switches of the current active
microphone.
The only exception here is that the microphones
of a delegate and the chairman can be active at
the same time.
Override:
Works like the FIFO mode; however multiple
microphones can be active at the same time. The
number of microphones that can be active
simultaneously is set by "Maximum Number of
active Microphones" setting.
When the maximum allowed number of
microphones are switched on, activation of an
additional microphone will automatically switch
off the microphone that was active for the
longest time. Again, the Chairmen units can
always be activated, regardless of the number of
microphones already switched on.
Note:
Choosing a high number of active
microphones will limit the number of
interpretation channels.

12.5. Encryption
12.5.1. Key Assignment
Introduction
To ensure a highly secured wireless system, the
Confidea system uses an encryption algorithm and
mechanism that is fixed and cannot be changed.
The information that is sent over the radio link is
encrypted with a key to make it inaccessible for 3rd
party equipment. This key is default and identical for
all Televic units.
Security can be increased by adding a custom key,
that is specific to a certain set-up or installation. Only
the units and access point that share the same
encryption key are able to communicate with each
other. In this way, the system has become customer
exclusive and as a result an even higher degree of
security has been reached.
Encryption Key
Default Key:
When selecting this key, information over the
wireless link is encrypted, using the Televic
default key, used by all Televic equipment
Custom Key:
To further increase security, or to limit the
access to the Access Point only to a well
controlled number of delegate units, a custom
key can be generated and send to those units
that are allowed to join. The result of this action
is that only the units that know this key can

Pressing this button will randomly generate a
128 bit key. The key appears in the window and
can still be edited by the user.
‘Upload’ key:
Pressing this button will upload the custom key
to all units, currently logged on to the system.
Units can only obtain the customer specific key
during initialization. As soon as the initialization
has been closed it will not be possible to access
the system with other units.

13. Initialization
13.1. Introduction
The system can be controlled by the WCAP in stand-
alone mode or together with the TCS2500 / TCS5500
Central unit in coupled mode.
In stand-alone mode it is not required to initialize the
units. However, if you want to authorize the wireless
units that will be connected into the system you can
follow the unit initialization procedure.
In coupled mode, the same initialization procedures
have to be followed as defined in the documentation
from the central unit.
To personalize the system and to further extend the
confidentiality of your wireless conference system a
unique encryption key can be defined.
13.2. Stand-alone mode
13.2.1. Access modes
When you use the Confidea system in stand-alone
mode, i.e. with no connection to a TCS2500 or
TCS5500 central unit, the WCAP is responsible for the
unit initialization and access control.
In stand-alone mode, the WCAP supports two kinds
of access: open access and controlled access.
Open access: This is the default mode. Any unit
can connect to the WCAP without authorization
procedure
Controlled access: a unit can only connect after
going through an initialization and authorization
procedure.
13.2.2. Selecting the Access Mode
To select the desired access mode go to the “Init
Units” sub tab in the “Conference Management”
menu from the web server (refer to Figure 13.1)
Figure 13.1: Web server init page selection
The following screen will appear:
Figure 13.2: Unit init page
Confidea Wireless System

To select ‘Open Access’ click the radio button next to
‘Open Access’ on the ‘Init Units’ page (refer to Figure
13.3)
Figure 13.3: Init units page - Open access
Select this mode if the wireless units are not required
to be authorized, before they are allowed to connect
with the WCAP.
This mode is especially useful for a fast setup.
To select ‘Controlled Access’ click the radio button
next to ‘Manual’ on the ‘Init Units’ page (refer to
Figure 13.4)
To control which wireless units connect with the
WCAP a manual initialization of the units is required.
Figure 13.4: Init units page - Manual
13.2.3. Unit initialization in
‘Open Access’ mode
Switch on all wireless units and wait a few seconds
until the units have discovered the WCAP (see
chapter xxx)
All active wireless units will automatically connect
with the WCAP and join the conference.
13.2.4. Unit initialization in
‘Controlled Access’ mode
In this mode, a manual initialization is required.
The manual initialization procedure requires the use
of the 3 buttons on the web server displayed above:
“Start Init”, “Save and Stop Init” and “Clear Init List”.
Take the following steps to initialize all units:
7. Switch on all wireless units and wait a few
seconds until the units have discovered the
WCAP (see chapter xxx)
8. Select the “Clear Init List”, , to
clear any previously created initialization list.
9. Start the new initialization by selecting the “Start
Init”, ,button.
After you started the new initialization, the LED’s
on all wireless units will start to blink.
10. To add a unit to the initialization list, press the
microphone button of the unit to add.
11. The LEDs will go out indicating that the unit has
been added to the list.
12. Repeat step 3 for each unit that needs to be
added.
13. When finished, stop and save the initialization by
pressing the “Save and Stop Init” button,
.
Note:
Avoid using Open Access in areas with
more than one active Confidea system,
as there is no control over which WCAP
the delegate units will connect to.

Only the units that are have been initialized and
listed in the Init List will now be able to join the
conference.
The init list is stored in the WCAP and stays in
memory even after switching the WCAP off.
Next time the WCAP and delegate units are switched
on, only these units that are in the Init List will be
allowed to connect to the WCAP.
13.2.5. Adding a new unit in
‘Open Access’ mode
In ‘Open access’ mode, adding a unit requires simply
to switch the unit on.
It will then automatically connect to the WCAP in
operation.
13.2.6. Adding a new unit in
‘Controlled Access’ mode
In a ‘Controlled Access’ set-up, adding a unit requires
the following steps:
14. Switch on the wireless unit to add and wait a
few seconds until the unit has discovered the
WCAP (see chapter xxx)
15. Open the existing initialization by selecting the
“Start Init”, , button.
16. After you started the new initialization, the LED’s
on the wireless unit(s) will start to blink. The
LED’s on the units that are already known in the
init list will automatically go out.
17. Add the new wireless unit(s) by pressing the
microphone button on the unit(s).
18. Stop and save the initialization by pressing the
“Save and Stop Init” button, .
Note:
When multiple WCAPs with ‘Open
Access’ are in operation in the same
area, there is no control over which
WCAP the new unit will connect to.

13.2.7. Reviewing Init information
At any time it is possible to see how many units are
known by the system, “Units in Init List”, and to see
which units are actually connected with the WCAP,
“Units Initialized”.
This information is visible in the “Unit Monitoring”
and “Init Units” sub tabs in the “Conference
Management” menu (see Figure 13.2)
Figure 13.5 shows the information on the screen
when 1 unit is listed in the Init List but not connected
with the WCAP:

14. Encryption
14.1. Introduction
To secure all communication between the WCAOP
and the wireless delegate units, all information that
is passed over the radio link is encrypted by default,
using a default encryption key. This key is identical
for all Televic equipment.
To this default key, a custom encryption key can be
added. This further enhances the confidentiality, but
can also be used to control access in an environment
where multiple adjacent rooms are using a Confidea
conference system. In this way, access can be
restricted to a single room or a selection of rooms.
The custom key as it were adds a unique relationship
between a wireless unit and a given access point.
14.2. Default encryption
By default the system uses an encryption mechanism
that is known by each unit in the wireless conference
configuration.
By using this setting it is possible to add new units in
the conference configuration or using the delegate
units with other WCAP’s at any time (also see
Initialization)
14.3. Setting the default
encryption
The default encryption mechanism can be set by
following these steps:
19. Select the “Key assignment” sub tab in the
“Encryption” menu from the web server.
Figure 14.1: Web server key assignment page selection
The following screen will appear:
Figure 14.2: Key assignment page
20. Select the “Use default key” option to return to
the default encryption mechanism
Figure 14.3: Default key selection
Note:
The advanced encryption mechanism
used in the Confidea system makes
decryption by third party equipment
practically impossible.

Installation and User Manual
Televic Conference Systems

14.4. Custom encryption
The Confidea wireless conference system can be
personalized by defining and selecting a unique
encryption key.
By using a customized key, only the units that have
this key, i.e. on which the specific key has been
uploaded, can connect with the WCAP. All other
units will be rejected.
It is impossible to receive the transmitted audio
signal with a unit that does not have the customized
key.
Up to 3 (TBD) customized encryption keys can be
defined.
14.5. Setting a customized
encryption
To set up your system with a custom encryption key,
carefully follow these steps:
Step 1 - Check your configuration
Before uploading the custom key check if all units in
your system are switched on and connected to the
WCAP. Verify if the correct number of units is logged-
on by checking the “Units Initialized” number which
can be found under the “Unit monitoring” or “Init
Units” sub tabs in the “Conference management”
menu. Please refer to the initialization chapter (ref.)
for more information.
Step 2 – Go to the Key assignment web page
Select the “Key assignment” sub tab in the
“Encryption” menu from the web server (refer to
Figure 14.1.)
The key assignment page will appear (refer to Figure
14.2)
Step 3 – Enter a new encryption key
In this example we will modify custom key 1.
To manually enter a new custom key, choose a 32-
character long encryption key and manually enter it
in the text box next to the “custom key 1” mark
(refer to Figure 14.4).
Note:
Once uploaded to the delegate units,
custom keys cannot be retrieved from
the system.
Note:
The basis of the encryption mechanism
cannot be altered, so adding a custom
key does not affect the encryption
strength.
Default- and custom encryption yield an
encryption strength that is equally high.

Alternatively, the system can generate a random
128-bit (32 hex characters) encryption key for you.
To do this, click the “Calculate 128-bit full key”
button (refer to Figure 14.4).
Figure 14.4: Custom key entry field
Step 4 – Upload a new encryption key
After a key has been generated it must be uploaded
into the system. Not only the WCAP, but also all
wireless delegate units that need to connect with the
WCAP must know the same key.
Upload the key by clicking the “Upload key” (refer to
Figure 14.4)
Step 5 – Activating the new encryption key
The WCAP will start encrypting the transmitted data
and audio after a custom key has been selected.
Figure 14.5: Custom key selection
If the WCAP needs to use the selected key next time
it powers up, push the button.
Caution:
Wireless units not containing the same
encryption key as selected, because they
were not connected with the WCAP at
the time of upload, can no longer
connect with the same WCAP.
The units will be ignored by the system!
Note:
During the upload, the microphone LEDs
will flash.
Once the upload is successful, the LEDs
go out.
Caution:
Only use hexadecimal characters i.e.
choose 32 characters from the
following list:
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d, e, f.
If a key shorter than 32 characters has
been entered, then the remaining
positions will be filled with zeros.
If a key longer than 32 characters has
been entered, then the key will be
truncated after the first 32 characters.

15. Stand alone system
15.1. Basic discussion
In a basic setup where only discussion is applicable,
the Wireless Conference Access Point WCAP (see link
to chapter WCAP) acts as a central control unit.
This means the system can operate without the need
of an extra central control unit (CE2500 or CPU5500).
Units applicable to this setup are listed below:
Confidea DD
Confidea CD
In a standalone configuration power needs to be
supplied to the WCAP separately. (see chapter WCAP
power supply)
Configuration and monitoring of the system can be
done via the build-in web server, which is accessible
via a standard web browser. (See chapter system
configuration)

16. Connected to
CE2500 or CPU5500
As the Confidea system is an addition to the Televic
product family it is also possible to combine the
Confidea system with the existing TCS2500 and
TCS5500 system (refer to Figure 16.1: Televic Family
concept)
This family approach makes it possible to create a
conference system fitting every customer needs.
In situations where every now and then an extension
of the fixed conference system is required, adding
some wireless units can reduces the setup costs
drastically.
Depending on the demands of a project the central
control equipment of the TCS2500 or TCS5500 does
the job.
The Confidea access point (WCAP) can be directly
connected to one of the digital output busses of the
TCS2500 central control unit. (CE2500/B)
Connecting the Confidea access point to the central
control equipment of the TCS5500 requires an
additional splitter unit (SPL5525).
In the following section three possible applications
are described. This will help to define the correct
system architecture for a given project.

16.1. Discussion
For these applications, delegates of the meeting have
a contribution unit with only a microphone to
participate in an ongoing discussion.
Several criteria can influence the choice of the
Televic central control unit to be used. The criteria
described below should guide you in designing the
best possible system architecture for a given project.
Figure 16.2: Central control equipment selection criteria
Project size
The number of participant units in a meeting will
influence the descision on the system to use.
The TCS2500 central control unit is limited up to 120
active delegate units.
Projects requiring a larger number of participants
should use the TCS5500 central control unit with
expandable system architecture.
Table 16.1 below gives an overview on the system
compatibility.

External Audio Peripherals
PA systems:
Whereas the Confidea units have a build in
loudspeaker, some meeting rooms are equipped
with external PA systems with loudspeakers
installed on walls or in ceilings.
Making use of such a setup, the floor language of
the conference system needs to insert into the PA
system. This requires an analog output, which is
available on the central control equipment of both
TCS2500 and TCS5500.
Recording:
Whenever meetings reports need to be written or
audio of meetings is being published on the web,
recording needs to take place during the meeting.
The recording device (hardware or software
solution) needs to have an analog input signal
provided by the conference system. Both the
Televic TCS2500 and the TCS5500 central control
units have 7 analog outputs available. Additional
outputs can be provided by adding external
TCS5500 output equipment to the TCS5500 system.
Audio reproduction:
Feeding external audio signals (music before
meeting, DVD sound, input external microphone,
telephone line, …) into the conference system
requires analog inputs on the central control unit.
Both the TCS2500 and TCS5500 central control
units have two analog inputs. If this is not
sufficient the TCS5500 system has the capability to
connect additional input equipment.

Connectivity
Operator Control:
Systems requiring a great degree of control can be
equipped with the Televic software suite.
This application makes it possible, depending on
the license, to control the microphones in a
meeting, assign delegate names, control speech
time, display delegate and speech time information
on monitors or projection screens.
It offers easy initialization and configuration
capabilities supporting an easy set-up and break-
down, essential for successive meeting planning
with low delays like convention centers.
Furthermore it visualizes the battery and RF quality
status of all units, giving the operator/technician
the ability to assure no interruptions once the
meeting started.
Camera Control
To enable a camera system to visualize the
currently active Confidea user, a device bus
controller needs to translate the commands
received from the Televic system into preset
positions of the camera control system. Both the
TCS2500 and TCS5500 systems will do the job.
The difference between the TCS2500 and the
TCS5500 system on connectivity level is the way the
communication takes place.
The TCS2500 uses a serial communication protocol,
whereas the TCS5500 system has additional IP
connectivity.

16.3. Interpretation
Systems with simultaneous interpretation as a
requirement always require a central control unit in
combination with the interpreter desks.
Installation
Whereas the TCS2500 interpreter desks are of the
table-top type, the TCS 5500 interpreter equipment
can be semi-flush mounted.
Conformity Standard
The ID5500 interpreter desk is conform to the XXXXX
standard and approved by interpreter organizations
as the European Commission (SCIC), United Nation,
AIIC.
Interpretation capabilities
The Confidea wireless system has the capability to
send up to 12 languages to the contribution units.
Both the TCS2500 and TCS5500 systems are capable
of handling that number of languages.
External Equipment
As already described in External Audio Peripherals
the number of analog outputs required for recording
or needed to connect to an Infra red distribution
system will determine the central equipment to be
used.
