Stegos – WLAN

For this reason the WLAN channels 1, 6 and 11 were selected for the RF channels Low, Mid and High

used for the Stegos system. Due to this frequency compatibility the Stegos system is operated WLAN-

friendly.

Due to careful frequency planning it is possible to operate one Stegos receiver and a maximum of two

WLAN devices nearby simultaneously.

More tips for installation

• Keep a minimum distance of approx. 5 m between WLAN or WiFi devices (e.g. Router, Repeater) and

the transmitting and receiving antennae of the Stegos RS receiver.

• If possible, deactivate all WLAN interfaces of laptops using the same frequency range as Stegos.

• The distance between the WLAN or WiFi and Stegos channels should be as large as possible.

• The channels of the Stegos system can be selected with the supplied Stegos software.

8.3 Stegos 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 Stegos system and an advanced transmission protocol.

• It cannot be excluded, however, that an exisisting Bluetooth data traffic will be intefered by Stegos.

8.4 Example for Stegos, media control systems 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 Stegos 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 Stegos system to the RF channel “Low”. The Stegos system then makes use of the

frequency range of 2401 to 2423 MHz. This frequency range must be reserved for the Stegos

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.
