What is the name of a bluetooth USB plug in? Or where to find one?

My boyfriend was describing a a USB plug in that has bluetooth. This way he can transfer pictures and music to and from his phone to his computer. I am completely computer or technology illeterate, so i was wondering what this is called and where is a good cheap place to find one (online or in a store)
I hope i am describing this correctly.

dknol answers:

It's called a bluetooth wireless USB adapter, you also need a phone tools program (usually they sell them both together) to make ringtones and other stuff.

How to turn a standard speaker into a wireless speaker?

I have a Behringer B215D Powered Speaker (–BEHB215D) that we use for all of our college parties and just whenever we are wanting to listen to music and hang out. Often we use a laptop or iPhone to play music from it via an an AV – Y Audio cable that at the end of the AV end we have an adapter that plugs straight into the input port of the speaker. Since both the Iphone and my computer is Bluetooth compatible I would like to find a way to play my speaker wirelessly via Bluetooth so I can have my phone or computer in a safe location instead of right next to the speaker when the party is going on. I understand that we may lose a little bit of sound quality jumping to a Bluetooth option but it's better then being out a phone or a computer if stolen. What I am more worried about is sacrificing the sound loudness of the speaker. Ideally I would like to keep the costs low, preferably less then $60 but I can spend upwards to $100 and I would also be willing to use CBI cables with it if that would fit my budget, bring out better sound quality and can be Bluetooth compatible since there is a port for that option as well. I appreciate the help, and if more info is needed I will be more then happy to give it to you.

I personally like the Bluetooth idea due to the high quality signal, lack of interference and respectable range. Here is an example that just might be the ticket…


At this price point it is definitely worth a try, keeping in mind that you will limit the distance when a wall is in the way. Amazon lists several, and of course there are other places to purchase one. Keep in mind that this IS just one – you will need a pair, one for each end of the signal.

Richard asks…

what is technology that makes the same channel reusable by different devices called?

for example we got 6 routers (Wi-Fi hotspots) and 6 PCs

* All 6 PCs are connected to 6 routers (pcA to routerA, pcB to routerB, … pcF to routerF)
* All 6 routers are working in one channel (1st of 13, for example)
* Each router has different SSID (naturally)

The question is – why can we use all of these routers just fine??

They are using the same frequency channel – so naturally I expect these frequencies to interfere one with another!

How many routers are allowed to use one channel and how can I calculate it?

I'm not interested in downsides such as: low signal strength and speed.
I'm interested in technology that makes the same channel reusable by different devices.
we got wi-fi, bluetooth, UMTS or whatever working on the same frequency – HOW do devices know that THIS signal is addressed to them via bluetooth, but not Wi-Fi. To me it looks like there's a bunch of electromagnetic signals flying here-and-there in the air but I don't understand how devices distinguish them so easily. Please explain on Wi-Fi example mentioned in the description ;) thanks

dknol answers:

Time division multiplexing is where the digital users take turns having access to the network. No digital device sends data continuously. It might seem that way in a long download or when streaming, but all data is divided up into packages called “packets”. These packages are sent one at a time. When sharing a network, the net controller decides what packet goes next. Each packet has an address of where it is headed, so receiving devices know if it is for them or not. Sending devices wait for a go-ahead from the net controller before sending out a packet.

Frequency division multiplexing is where bluetooth and WiFi use different frequencies for operation.
