can cellphone interfere with Cyton and dongle? [resolved]
@wjcroft Hi. In a software discussion under the title “large noise pulses on Windows, but NOT on Mac”, you wrote:-
“Noise pulses like shown on the original post can be the result of a noisy Bluetooth radio channel. By reducing distance between the Cyton and dongle, radio signal strength is increased. Extension cable can be one way to increase radio signal to noise ratio. Another way is to reduce interference from other Bluetooth/Wifi devices in the same area.”
Does a person using a cellphone near the dongle and Cyton +Daisy board interfere with the quality of EEG signals being recorded or streamed such that reducing the distance between the Cyton and dongle does nothing to reduce this interference? And, how far away should one use a cellphone in the vicinity of a dongle and Cyton board to eliminate or at least reduce this interference to a minimum?

Hi Scipio,
Generally cell phones are operating in a different RF frequency band than Bluetooth / Wifi. So it is not usually an issue. And even with other Bluetooth / Wifi devices, it is more a matter of the number of those devices and their proximity.
