Your Questions About Bluetooth Technology

Jenny asks…

what is the difference of an infrared to the bluetooth in cellphones?

how do infrared and bluetooth works in cellphones?

dknol answers:

Infrared (IrDA) is a optical wireless technology, it requires line of sight between two devices. The data transfer rate is limited and only a handful of phones still have IrDA. Bluetooth is radio frequency based wireless technology and does not require line of sight. They can operate in the range of 10-40m depending on the brand. Most of the new cellphones have bluetooth and there plenty of bluetooth based accessories such as bluetooth headset, speakers, mini keyboards etc.

Steven asks…

How do I transfer music to my mobile phone?

At the risk of sounding completely stupid, I have a new mobile phone but I don't know how to transfer music over to it. I'm a middle-aged guy though and a lot of technology has really past me by. I thought it was via USB but I didn't get a cable with the phone, and the ones I do have don't fit.

I'd be grateful if anybody could outline the steps I need to take to do it.

dknol answers:
