Why am I seeing dropouts while using Emotiv USB Receiver with the EMOTIV headsets?

This sometimes has dropout problems if the receiver is located close to a WiFi, Bluetooth or other 2.4GHz transmitters – which is often the case in a PC where the antenna is located conveniently next to the USB ports (Mac also has frankly awful electrical isolation so the entire case probably oscillates at 2.4GHz). We always use and strongly recommend using a USB extension lead or powered hub just to get the receiver out of the noisy environment next to the PC. Place it in clear air away from radio sources and in clear line of sight to the headset and your wireless issues may disappear.
