Stegos – Trouble Shooting188. Simultaneous operation of the Stegos system and other 2.4 GHz devices(e.g. WLAN, Bluetooth)8.1 Physical lawsDue to many physical laws it is not possible to guarantee a simultaneous interference-free operation ofdifferent devices using the same frequency band. Radio devices operating in the same frequency bandwill 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 samefrequency. It is only possible to operate a certain number of compatible radio devices within a definedfrequency band.This applies also to the 2.4 GHz-ISM band (2400 MHz - 2484 MHz). Due to digital transmission techniques and various transmission standards it is possible, but not recommended, to operate certaindevices simultaneously within the same frequency band.7. Trouble shootingProblem Possible Cause SolutionThe green operating controlLED ቤ of the boundary microphone will flash.• The rechargeable battery is almost empty.• Recharge the boundary microphone.The boundary microphone goesoff.• The rechargeable battery is empty.• Recharge the boundary microphone.It is not possible to allocate themicrophone.• The microphone is not withinthe range of the receiver.• Interference caused byWLAN• Reduce the distance betweenreceiver and boundary micro-phone.• Select another frequencyband with the push-button ᕤ.The boundary microphone cannot be turned on.• The rechargeable battery is empty.• Recharge the boundary microphone.The boundary microphone can be turned on, but not allocated.• The receiver is not turned on.• The microphone is not withinthe range of the receiver.• The channels in the StegosSoftware are not activated. • The number of the allowedmicrophones is exceeded.• Turn on the receiver.• Reduce the distance betweenreceiver and boundary micro-phone.• Activate the channels in theStegos Software. • Please note that 4 micro-phones can simultaneouslybe operated at maximum.
Stegos – WLAN 192400 MHz Low Mid High 2484 MHzFrequency /MHz8.2 Stegos and WLAN or WiFiLike WLAN, the Stegos system uses the same bandwidth of approx. 22 MHz for each RF channel (Low,Mid, High). This results in three compatible RF channels in the 2.4 GHz-ISM band. These 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)The Stegos system uses RF channels (Low, Mid, High) compatible to each other. For WLAN the user hasto configure compatible RF channels.Frequencies Stegos / WLANStegos WLANChannel Centre frequency Channel . . . . . . . . . . .

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 usein the USA. In general, these channels are not used either. Within the remaining frequency bands onlythe WLAN channels 1, 6 and 11 can be used simultaneously.
Stegos – WLAN20For this reason the WLAN channels 1, 6 and 11 were selected for the RF channels Low, Mid and Highused 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 twoWLAN devices nearby simultaneously.More tips for installation• Keep a minimum distance of approx. 5 m between WLAN or WiFi devices (e.g. Router, Repeater) andthe 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 (frequencyhopping). • 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 WLANThe 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 havedirect internet access via a WLAN access point.The Stegos system and WLAN make use of compatible transmission standards. This should be consideredwhen also using a media control system with a touch screen. State-of the-art devices correspond to theWLAN standard.1. Configure the Stegos system to the RF channel “Low”. The Stegos system then makes use of thefrequency 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 theuse of the touch screen exclusively.3. Configure the WLAN access point to WLAN channel 11 making use of the frequency range 2451 to2473 MHz. This frequency range must be reserved for the use by WLAN exclusively.
