Bluetooth and WiFi - an undesirable neighborhood

I think that none of you will deny that such friendly technologies such as Bluetooth and WiFi make it much easier (and shorten) our lives, making the interaction between devices at a distance of soft and silky. However, today I discovered a horrible fact - Bluetooth and WiFi dongle is better not to keep the neighboring USB connectors.

My house has a MiFi - Huawei E560. The finest thing in the Internet delivers an old village house, in which there was not and will not be a wired telephone, wired Internet, and anything else wired, except for electricity. Previously, the Internet home of the veteran was provided with the Russian mobile connectedness of the country - USB-Modem Option iCon 225, which is at the dawn of the emergence of mobile Internet was bought for three thousand mad at Beeline and from which even the Beeline now denies saying, they say, was not we have such a modem. It is self-branded modem with nakleechkoy and, kind of like, zalochenny. Now, having tasted all the delights of WiFi-router NetGear JWNR2000v2, which I already have a couple of months working in a city apartment to deliver the Internet to a PC I bought in the village of the same to him and the MiFi WiFi-dongle Trendnet TEW-649UB. Cheap and cheerful.

Dongle lived in a free USB-connector and began his work, from which the last couple of weeks I suffered constant interruptions of communication, strange "heavy" calls in Web-based router, and a slow Internet connection. While this connection to the MiFi from the tablet and smartphone was excellent. But why? Because WiFi-dongle for the PC, I settled in the neighboring Bluetooth-dongle USB-connector.

Wikipedia tells us that "Bluetooth radio is in the ISM-band (English Industry, Science and Medicine), which is used in a variety of home appliances and wireless networks (free of licensing 2,4-2,4835 GHz range)." She also tells us that the WiFi standard b, g and n are also working in the same range of frequencies. What does this mean? CEP will explain all this noise and I have to agree. That they are.

That finding two dongles in close proximity explains that the transmit / receive via WiFi-dongle so tightly worked, giving me all sorts of inconveniences, and file transfer via Bluettoth completely blocked access to the Internet. Now WiFi-dongle is connected via a USB-extension cord and no problems with the quality of the signal does not. Laptops and other small tselnosbornoy technology, these modules, I believe, are shielded from each other, which is reasonable.
