Just been looking at cheap bluetooth dongles that transfer data a distance of up to 150m (enclosed) and 350m (open) for 6 each and wondered if these are suitable for popping in my desktops upstairs and downstairs to do quick simple file transfers. The cost seems very good .. didn't put a link to the product as I suspect I am not allowed. Any techy help appreciated. Are there any other obvious uses for them apart from helping me download files from my mobile easily?? Thanks ..

I'm no tech expert, but I should imagine the answer is yes - however it still might not be the best solution for you. Have you considered a router? Mine allows both PC's to connect wirelessly and I've added a network drive to the router directly for easy transfer of files and backup - even when either PC is off. Just a thought.

Also no expert, but bluetooth range is typically just 10 metres. So check your other device to see what its range is because you won't be able to pair devices over 100m unless they both have this range.

Thanks for the replies .. yes both usb bluetooth dongle devices are rated at 150m in encosed areas so accounting for the world not being perfect they should still transmit from upstairs to downstairs ... the good thing is that they are 6 each and so far cheaper than buying a router and adaptor for my old computers and also they create a bluetooth link to the PCs for the family mobiles, which wouldn't be the case with a router. I presume that I would just need one router and one adaptor to create a link between both PCs ... which will be significantly more expensive than two cheap dongles. Any tecchies out there that can give a a definitive answer.

Bluetooth devices come in three classes.
Class 3 radios have a range of up to 1 meter or 3 feet
Class 2 radios most commonly found in mobile devices have a range of 10 meters or 33 feet
Class 1 radios used primarily in industrial use cases have a range of 100 meters or 300 feet

Depending on the version of Bluetooth used the data rate is between 1 and 3 Mbps.

It is possible to set up a network using Bluetooth as described here .

Hope that helps.

Certainly worth having a try with them at the price.
Hope it works for you.

Worth a try .. if it turns out to have the transmission capabilities of two empty tins of baked beans and a piece of string then I will have done 12 and I will let you know ;0)
