1.3 System technology
1.3.1 Basic system concept
The system composition of HCS-5300 digital infrared
wireless conference system is shown in figure 1.2. It is
composed of:
Digital infrared wireless conference units for
participators
Digital infrared wireless conference main unit for
system control
Digital infrared transceiver(s) for connection to main
unit
The digital infrared wireless conference main unit
converts audio and/or control signals into carrier
outputs which are transmitted to the digital infrared
transceiver(s). In the digital infrared transceiver(s) the
carriers are converted into modulated infrared light,
sent to all digital infrared wireless conference units.
The digital infrared transceiver(s) also receive infrared
signals from every digital infrared wireless conference
unit and convert the signals into audio or control
signals which are transmitted to the main unit.
Figure 1.2 The basic system concept
1.3.2 IR radiation
Audio and control signals of HCS-5300 are transmitted
as modulated infrared light. Infrared radiation is part of
the electro-magnetic spectrum, which is composed of
visible light, radio waves and other types of radiation.
Its wavelength is longer in comparison with the
wavelength of visible light.
Infrared light cannot pass through opaque walls and
ceilings and guarantees privacy of the meeting by
avoiding of being intercepted or disturbed. In addition,
infrared light has no radio radiation and a license is not
required when operating infrared light systems.
1.3.3 Carriers and channels
TAIDEN HCS-5300 digital infrared wireless conference
system adopts 2-8 MHz wave band (IEC 61603 BAND
IV), shown as figure 1.3. This wave band is suitable for
the transmission of wide band audio and corresponding
signals. HCS-5300 uses 6 frequency points of BAND
IV (please refer to table 1.1.)
Figure 1.3 Standard wave band in HCS-5300 system

To benefit from the advantages of a digital infrared
wireless conference system the signals should be
transmitted undisturbed. This is achieved by using
digital infrared transceivers well positioned and
sufficient in quantity to ensure uniform and adequate
infrared radiation for all conference units.
Just like visible light, infrared radiation is reflected from
hard surfaces and refracted by hyaloid (glassy or
transparent appearance) items. Objects in the
conference venue as well as structure of the walls and
ceilings will influence the distribution of infrared light.
Infrared radiation is reflected from almost all hard
surfaces. Smooth, bright or shiny surfaces reflect well.
Dark or rough surfaces absorb a large part of the
infrared energy. Usually, surfaces opaque to visible
light are also opaque to infrared radiation.
When planning a digital infrared wireless conference
system, several aspects influencing the uniformity and
quality of the infrared signal should be considered.
These are discussed in the next sections.
Shadows from walls and furniture will influence the
transmission of infrared light. This can be solved by
using a sufficient quantity of transceivers. They should
be positioned in a manner to provide an infrared field
strong enough to cover the whole conference area.
1.4.1 Ambient lighting
HCS-5300 system adopts 2-8 MHz wave band, and
has very good anti-interference performance (see
figure 1.4, figure 1.5).
Make sure that each infrared wireless conference unit
can communicate simultaneously with at least two
transceivers to guarantee stable adequate infrared
signal transmission.
Figure 1.4 High frequency lights disturbance from HF
driven light sources (energy-saving lamps)
Figure 1.5 Digital infrared conference system with 2-8
MHz wave band can avoid high frequency lights
disturbance
For meeting rooms with large, unscreened windows,
multi-transceiver operation should be considered. For
outdoor using, a site test will be required to determine
the needed amount of transceivers. With sufficient
transceivers, perfect signal transmission can be fulfilled
even in bright sunlight.

1.4.3 Infrared service area of digital infrared wireless conference unit
Infrared light is directional invisible light. Infrared
wireless conference unit gets best sensitivity when it
directly faces a transceiver. Every HCS-5300 series
digital infrared wireless conference unit is equipped
with infrared glass at its frontage to guarantee
maximum receiving angle.
In the vertical direction, the user can select "Vertical",
"Horizontal" or "V+H" work area according to
transceiver installation location, to ensure the most
effective sending and receiving infrared signals.
Figure 1.6 Coverage area of digital infrared wireless conference unit

1.4.4 Infrared service area of digital infrared
transceiver
The type of the digital infrared transceiver determines
the covering area. More transceivers can enlarge the
covered area.
The coverage area (the red area in figure 1.7) is
determined by the intersection of the infrared working
area of the digital infrared transceiver(s) with the
receiving plane determined by the position of the
infrared wireless conference unit.
If infrared signals between the transceiver(s) and the
conference unit can get directly to each other, their
intensity guarantees normal communication.
As can be seen, the size and the position of the
coverage area are related to the height chosen for
mounting the transceiver.

Figure 1.7 Coverage area of digital infrared transceiver
1.4.5 Overlap and multipath effects
If footprints of two transceivers overlap, its total
coverage area may be larger than the sum of the two
separate footprints. In an area with overlap effect, the
individual radiation signals of two transceivers are
added, resulting in an increase of the radiation intensity,
larger than the required intensity.
Figure 1.8 Increased coverage area caused by added
radiation power
However, due to the differences in the delays of the
signals from two or more transceivers, the signals may
cancel out each other (multipath effect). In a
worst-case situation, loss of reception at some
positions (black spots) may be the consequence.
The distance between the main unit and each
transceiver must be equivalent to avoid multipath
effect.

differences in cable signal delay
