9.1 Simultaneous Operation of the MCW-D Discussion System and other 2.4 GHz Devices
(e.g. WLAN, Bluetooth)
Due to many physical laws it is not possible to guarantee a simultaneous interference-free operation of different devices using the 2.4 GHz
band. Therefore, we recommend to operate always one application in this frequency range.
In general a simultaneous operation of the MCW-D discussion system and standard applications such as WLAN, Wi-Fi or Bluetooth is possible
due to some technical precautions.
Please observe the follwoing recommendations to avoid interferences.
MCW-D and WLAN or Wi-Fi
• Keep a minimum distance of approx. 5 m between WLAN devices (e.g. Router, Repeater) and the transmitting and receiving antennae of
the MCW-D control unit. The distance between notebooks with activated WLAN interface and microphone unit should not be less than 50 cm.
• We recommend to use different RF channels for WLAN and MCW-D channels. The channels of the MCW-D discussion system can be
easily selected with the supplied MCW-D Editor Software.

Bandwidth 7 MHz / channel
Note:
The bandwidth of the channels overlap and cannot be used simultaneously therefore.
Example:
WLAN operates on channel 11 (= 2462 MHz). As a consequence MCW-D cannot use the whole range from 2449 MHz to 2475 MHz without
any limitations. Therefore, MCW-D should use the (MCW-D) channels 0,2,4,6,8.
MCW-D and Bluetooth
• Bluetooth devices make use of the whole 2.4 GHz range with changing carrier frequencies.
• Mobile phones and laptops with integrated and activated bluetooth interface need a minimum distance of 50 cm to the MCW-D
microphone units.
Solution
• Perform a reset at the multi-
function socket on the rear of the
microphone unit. Please refer also to
chapter 12. Technical Specifications -
Microphone Units.
