8.1 Simultaneous Operation of the Quinta Conference
System and other 2.4 GHz Devices
(e.g. WLAN, Bluetooth)
8.1.1 Physical Laws
Due to many physical laws it is not possible to guarantee a
simultaneous interference-free operation of different devices using
the same frequency band. Radio devices operating in the same
frequency band will always disturb each other (the function can be
disturbed as well).
For the use of UHF wireless microphones it is known that 2 devices
can never be operated on the same frequency. It is only possible to
operate a certain number of compatible radio devices within a
defined frequency band.
This applies also to the 2.4 GHz-ISM band (2400 MHz - 2484 MHz)
or 5 GHz. Due to digital transmission techniques and various
transmission standards it is possible, but not recommended, to
operate certain devices simultaneously within the same frequency
band.
8.1.2 Quinta and WLAN or WiFi
Like WLAN, the Quinta system uses the same bandwidth of approx.
22 MHz for each RF channel (Low, Mid, High). This results in three
compatible RF channels which are theoretically:
Compatible channel 1: 2400 MHz - 2428 MHz
(theoretical mid frequency 2414 MHz)
Compatible channel 2: 2428 MHz - 2456 MHz
(theoretical mid frequency 2442 MHz)
Compatible channel 3: 2456 MHz - 2484 MHz
(theoretical mid frequency 2470 MHz)
Compatible channel 4: +5.2 GHz - +5.8 GHz
The Quinta system uses RF channels (Low, Mid, High) compatible
to each other. For WLAN the user has to configure compatible RF
channels.
You can easily recognise that the individual WLAN channels overlap
considerably due to their bandwidth. All neighbouring channels
(e.g. channel 1 & 2 or channel 7 & 8) cannot be used simultane-
ously, because they would disturb each other. Furthermore, channel
12 and 13 are not approved for the use in the USA. In general, these
channels are not used either. Within the remaining frequency bands
only the WLAN channels 1, 6 and 11 can be used simultaneously.
For this reason the WLAN channels 1, 6 and 11 were selected for the
RF channels Low, Mid and High used for the Quinta conference
system. Due to this frequency compatibility the Quinta system is
operated WLAN-friendly.
More tips for installation
• Keep a minimum distance of approx. 5 m between WLAN
devices (e.g. Router, Repeater) and the transmitting and
receiving antennae of the Quinta CU control unit.
• The distance between laptops with activated WLAN interface
does not influence the audio transmission of the microphone
units as long as there is no active data traffic.
• We recommend using different RF channels for WLAN or WiFi
and Quinta channels. The distance between the WLAN and
Quinta channels should be as large as possible.
• The channels of the Quinta conference system can be selected
with the supplied Quinta Conference Software.
