    Check out this Bluetooth adapter that's being sold on eBay. They say it has a range of 100m (over 300 feet). Can this be right?

    Hey Andrew,

    BT devies typically come in three Classes (I,II,III) with Class I obviously having the largest range and power consumption. Most BT headsets for mobile phones are Class III, and I also believe the 650 only has a Class III BT radio. Thus this would make sense as a Class III BT device, but note that BOTH devices would need to have Class I to get that full range...

    Power Class Maximum Output Power
    1 100 mW (20 dBm)
    2 2.5 mW (4 dBm)
    3 1 mW (0 dBm)

    Class I will work with class III, right?

    Thanks gfunk. Is there a long-range bluetooth adapter that I can buy pre-built? I want to sit in my living room and use by bedroom's bt to log on to the net or hotsync. I know I can solder an antena on to a bt adapter, but nothing good can come from me trying to melt metal.

    Yeah sure, but remember both devices have to be class I to get the full range! Thus the range of the connection is always limited by the weakest radio..

    Sorry, I don't know anything about that! But you might as well try using a Class I. I read people getting pretty good range with their Treos even though it only has a class III bt radio...

    I use the Linksys USBBT100 (class I), and I can connect using bluetooth from anywhere in my house.

    This is a very common misconception

    Range of connection has two major factors

    transmit "strength" of transmitter/antenna system

    receive "sensitivity" of receiver/antenna system

    I can communicate with our "wimpy" treo650 bluetooth radios from many, many miles away by simply building a very sensitive antenna that can hear our weak treo650 signal and also by transmitting a higher power/more efficient RF signal that will get to the treo650.

    The linksys usb-bt100 adapter that everyone is raving about, uses a high power transmitter and a nice adjustable receiver antenna to acheive this.

    AndrewTreo:

    The link you posted looks like a copy of the linksys USBBT100 that everyone likes because of the great range. Purchase a Genuine Linksys one from newegg here:


    link to adapter


    it should definately give you the range you need.
    Mine works like a charm. I can update the firmware on my permanently installed bluetooth handsfree car kit, while it is out in the driveway!

    Good luck

    I got mine from Amazon for $39. It only took me a few minutes to set it up. The wizzard set up is very easy.

    I bought a cheap-o usb adapter for my pc, and I'm not sure the full range, but I am able to use it throughout all 3 stories of our house via PPP and my Treo to connect to the internet.
