Bluetooth Broadband home connection

You can use it to connect to your ADSL line if you have a BT access point
which is connected to the ADSL line. The question I have is why would you
want to do this? Do you have more than one PC that you want to connect to
the ADSL line? If the answer is yes, do you intend to connect them through
Bluetooth to ADSL? Or are they already hardwired to ADSL perhaps through a
router/hub connection?

If you are going to purchase a Bluetooth access point to connect a single PC
to your ADSL line I would advise getting an inexpensive network card and
connecting directly to the ADSL "modem". It would be far cheaper and
probably better performing in the long run.

So the short answer is yes you can but perhaps if you could share with us
your current configuration and what you really want to do then there might
be an even better alternative.

Thanks for the recommendations.

I am running a single PC which I wish to connect directly to ADSL. I
originally purchased the Bluetooth USB adaptor in order to easily
exchange files between my Ericsson T610 mobile phone and my PC.

My initial idea was to save money on setting up a broadband connection
by using hardware that I already had. The logic being I could somehow
install one inexpensive piece of technology between the USB adaptor
and the telephone, get the ADSL line enabled with the telephone
company then finish it all off with an ADSL subscription with a cheap
broadband ISP.

The other secondary advantage being that I can relocate my PC to
another location in my house away from the telephone socket.

I have assumed that the Bluetooth will provide a similar speed
connection to ADSL to the cable alternative. Is this correct?

Comparing it to signing up with one of the ISPs who will provide a
cable modem, filters etc, tie me down to a 12month contract with an
expensive monthly bill it seems in theory like a good idea. Also the
cable way seems like I am adding unnecessary hardware and ignoring the
existing hardware capabilities of my system.

So...summing up do I need to buy a network card and an ADSL modem to
get this 'wired'?. I was in naivity hoping that the USB adapter would
do all the modem work and all I would need to purchase would be
another similar device that neatly fitted into the phone socket.

Am I right in thinking that the basic configuration you suggest is :
???

[PC] - [network card] - [ADSL modem] - [phone socket]


I had entered into this project thinking that this would be a simple
and logical module in the world of wireless data exchange, and have
unexpectantly ventured into a confusing world of networking and
routing jargon previously unknow to me.

The configuration you show here is correct. And the network card will be
cheaper than a BT Access Point - much cheaper. Of course you have the cable.
But if you're using ADSL, I'd suggest installing wi-fi instead of Bluetooth
for this specific use.

http://www.adslguide.org.uk/ is a good place to go for background reading.

Bluetooth doesn't have all that much bandwidth (figures I have seen so far
give two speeds - about 750kbits/sec and 450kbits/sec).
The lower figure is less than the bandwidth available on ADSL.
Further, although I have not yet seen a discussion on the real bandwidth
available over bluetooth, you may not achieve the theoretical maximum due to
inefficiencies and signal strength/interference.

What do you need?
[in the UK 'uk.telecom.broadband' is a good NG]

(1) You get your phone line ADSL enabled
[If you are in the UK you won't need a 12 month contract and you can have a
'wires only' installation where you supply all the equipment.]

(2) Microfilter(s) to seperate phone and ADSL traffic.
[Get good ones - cheap ones are false economy]

(3) ADSL modem.

With one PC (and a USB modem) this is as far as you need to go - however a
Windows PC is very vulnerable to attack when connected directly to the
Internet so you also need a firewall and some brown trousers.
USB modems can have performance problems also.
Finally you can do better for the same money :-)

So:

(3a) Better to get a modem/router instead of a modem - about the same price
and the router provides a considerable amount of protection just by being
there.

or in your case:

(3b) You can get a modem/router/wireless (WiFi or Bluetooth) access point
for not much more.

See http://www.nemax.co.uk/NETWORKING.html for an example - not recommending
this site, I just Googled my way to it and it seemed to offer a reasonable
comparison.

You can get the Bluetake Bluetooth Access Point for £70.80 + VAT. (note this
is just an access point - you would need a compatible modem/router as well
see (3a)) The extra bits could cost another £50 or so.

You can also get an ETEC wirelss ADSL modem/router (i.e. all you need in one
box) for £74.28 + VAT. If your PC is not wireless enabled then you can get a
USB WiFi 'dongle' for about £20-£25.
This give you 802.11b connectivity with a maximum of 11Mbits/sec bandwidth
and a much greater range than Bluetooth.

NOTE: This is not a recommendation - just using this site and its prices for
illustration!

So in summary it is probably cheaper for you to equip yourself with a
complete 802.11b solution than to add ADSL access to your existing Bluetooth
setup. You will also get more range and performance.

IMHO Bluetooth is currently best used for PAN applications where you are
exchanging low volumes of data between personal devices. Great for linking
up with others in meetings but strictly short range (10 metres ain't that
far).

For LAN connections, especially to the Internet, WiFi is currently a much
better solution.

If you have Bluetooth enabled PCs the LAN profile is an added bonus.

For a real LAN in house (large file exchanges, streaming video, data backups
etc.) wires (100Mbits/sec full duplex) are still the best option.
