Can Mobile DJ interfere with WLAN networks?

Mobile DJ communicates with its USB dongle in a proprietary 2.4 GHz protocol: it uses neither WIFI nor Bluetooth. Mobile DJ proprietary protocol operates at a base frequency of 2.407GHz, and when it detects noise in its frequency, it moves by steps of 250KHz to the next noise free frequency channel.
The dynamic frequency adjustment lets Mobile DJ adjust to 2.4 GHz wireless networks (WIFI, Bluetooth) so that
- Mobile DJ doesn’t interfere with wireless networks,
- and the wireless network doesn’t interfere with Mobile DJ.

You should place Mobile DJ USB dongle at 2 feet or more from any other 2.4 GHz transmitter (WIFI, Bluetooth or audio/video proprietary transmitter) to get a good transmission range, since if they are closer, both systems will continuously jump from 1 frequency to another to avoid each other disturbance, and such continuous channel changes reduce the transmission range.

For the same reason, you should place a WLAN device at least 2 feet away from another 2.4 GHz device (Bluetooth, audio/video transmitter..) to optimize the range of your WLAN network.
