Quinta – Trouble Shooting
20
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 simultaneously, 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.
Due to careful frequency planning it is possible to operate one Quinta CU control unit with more than 4,000 microphone units and a maximum
of two WLAN devices nearby simultaneously.
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.
7.1.3 Quinta and Bluetooth
• Bluetooth devices make use of the whole 2.4 GHz range with changing carrier frequencies (frequency hopping).
• Interferences caused by Bluetooth devices (including microwave ovens) in normal operation can be excluded due to different measures
inside the Quinta conference system and an advanced transmission protocol.
• It cannot be excluded, however, that an exisisting Bluetooth data traffic will be intefered by Quinta.
7.1.4 Example for Quinta, Media Control System and WLAN
The 2.4 GHz technology is used for many applications in discussions and meetings. In addition to a wireless discussion system other
functions (light or volume control etc.) are operated via a wireless 2.4 GHz touch screen of a media control system. Furthermore, the
participants of a meeting often have direct internet access via a WLAN access point.
The Quinta conference system and WLAN make use of compatible transmission standards. This should be considered when also using a media
control system with a touch screen. State-of the-art devices correspond to the WLAN standard.
1. Configure the Quinta conference system to the RF channel “Low”. The Quinta system then makes use of the frequency range of 2401 to
2423 MHz. This frequency range must be reserved for Quinta exclusively.
2. Configure the touch screen of the media control system to the frequency range of 2426 to 2448 MHz. This corresponds to the WLAN
channel 6. This frequency range must be reserved for the use of the touch screen exclusively.
3. Configure the WLAN access point to WLAN channel 11 making use of the frequency range 2451 to 2473 MHz. This frequency range must
be reserved for the use by WLAN exclusively.
4. As an alternative you can operate Quinta in the 5.2 or 5.8 GHz band.
