Is there a Bluetooth PCI card that is *just* bluetooth (and not combowifi) ?

    I see that there are some really cheap combo cards that do 802.11 B/G
    (not N) and also do Bluetooth. I've read where those cards are
    CPU-intensive (they have a DSP and make the computer's CPU do all the
    work - ??). They also don't use (or are not compatible with) Microsoft's
    Bluetooth stack (what-ever implications or consequences that has - I
    don't know).

    I was wondering if there was a good (high-performance, long-range)
    bluetooth-only PCI card?

    A card that is compatible with an external, high-gain antenna?

    And if I have to get a combo PCI card just to get bluetooth, is there at
    least a card that will do 802.11 N as well as bluetooth?

    Are we talking about the tcp/ip stack here?

    Or is the bluetooth stack something different than the TCP/IP stack?

    And what, exactly, are the consequences of a PCI bluetooth card that
    can't run using Microsoft's bluetooth stack?
    Yea, I came across that exact item before I posted my original question
    here. I was wondering if there weren't more of those, perhaps with
    availability showing at some US retailers.
    Win-98 would be ideal, but I'd settle for XP.

    Because I want a long-range solution. I mentioned I wanted to use an
    external antenna to maximize the range. Are there any bluetooth usb
    dongles or transceivers that have external antenna jacks?

    I want to see how far I can receive signals from one (or more) very
    small bluetooth-capable GPS loggers.
    Yes, there are (or were) bluetooth drivers for win-98 for the bluetooth
    hardware that came in some laptops in 2004 (and probably for other

    The German-made PCI bluetooth card mention in the previous post has
    win-98 drivers (according to the specs).

    $129 isin't bad
    It's not uncommon for a device to state that it's not compatible with
    win-9x, but burried deep somewhere on it's driver CD will be a win-9x
    directory. But ok, maybe no win-98 driver.
    In this case, because it's larger than the tip of your thumb, and
    because it's designed to act like a long-range base station using a
    large external antenna, the fact that it's usb doesn't matter.

    But answer this. If Bluetooth is designed to *not* have a range
    exceeding 100 meters, then how can the above-mentioned device exist and
    function as advertized - with a range of at least a mile?

    Your understanding is not correct.

    Blue tooth is a digital radio communication protocal. It doesn't matter
    if the electronics that is performing the radio communication is
    embedded in an external box, or on a PCI card, a thumb-sized USB stick,
    a pair of wireless headphones or a cell phone.

    It also doesn't matter how the radio transciever part of the device
    receives data, be it serial port, usb port, or PCI motherboard

    I'm jumping in here but the design for consumer products is Bluetooth
    = short range.

    It seems you want; bluetooth, long range, internal (pci), & cheap. I
    really don't think there is such a ting made.

    If I had two walkie-talkies, and they both had the same small antenna
    and the same low-power transmit circuit, then they'd have a short range.

    But if I took one of them and boosted the transmit power, AND gave it a
    huge antenna, then in theory I'd be able to extend the range even if one
    of them still had it's small antenna and weak transmitter.

    Same applies here to this bluetooth situation. If the PC's bluetooth
    radio had a strong transmit circuit, and if it had a large, high gain
    antenna, then it's transmit range and it's receive sensitivity would
    enable the communication range to be extended to typical, standard
    low-range bluetooth devices.
    I only specified PCI because I didn't believe there was a USB solution
    that had an external antenna capability.

    But clearly since Microsoft's BT stack only supports USB, then that
    creates a preference for a USB solution over PCI from a software POV.
    Given that preference, one result is the high-power, long-range BT
    transceiver mentioned in the previous post

    $129 isin't so expensive if it means extending BT range from an anemic
    few dozen feet to potentially a few thousand feet.

    Tell me who's dreaming:


    AIRcable Host XR™

    The only long-range (10 km-class) Bluetooth® USB "Dongle"

    The AIRcable Host XR, equipped with an extremely-powerful,
    highly-sensitive Bluetooth transmitter, can achieve an unparalleled
    range of up to 30 km! With a 9 dBi omni-directional antenna, the
    extended range is up to 2 km, and with the 18 dBi directional antenna,
    it is up to 10 km.

    Additionally, given its high sensitivity, it can extend the range of
    weaker Bluetooth devices like cell phones and headsets by hundreds of
    meters. With most other devices only capable of obtaining a range of 10
    meters or less, no other Bluetooth device comes even close. Plus, this
    long-range Bluetooth transmitter connects to any computer with a
    Bluetooth connection and can handle virtually any Bluetooth profile

    Uses include standard data, streaming data, headsets communication (like
    Skype calls), and stereo headphone communication, amongst others.

    With the AIRcable Host XR you can extend the range of communication from
    your PC to other Bluetooth devices.

    The AIRcable Host XR's Bluetooth radio receiver is many times more
    sensitive than the average Bluetooth device. You can expect about a 10
    times more range than with other standard Bluetooth dongles.

    OK, I'll look a little more into this to satisfy my own curiosity,
    good luck w/ that.

    You. You aren't going to get two orders of magnitude improvement in signal
    strength [or distance covered] by merely changing your Bluetooth dongle and

    So you are disputing the engineering concept that the size and placement
    of an antenna can affect radiated signal strength, pattern and
    transmission / reception range?

    You are basically saying that the antenna that's built into the small
    USB dongles are just as effective as large, externally-mounted antennas.

    You are also disputing the concept that when given the luxury of more
    PC-board real estate for a device, that you can frequently build a
    device with more features or better performance if you aren't restricted
    by the size of the device envelope.

    It's clear that either you don't understand basic engineering
    principles, or you're also dreaming.

    You seem to be saying that the extended-range bluetooth tranceiver being
    sold AIRcable is a complete fabrication - that it's range specifications
    are completely bogus.

    Perhaps you can tell us what your credentials are, what your argument
    is, that enables you to put forward a convincing argument to support
    your statement above?

    You should probably read more recent posts in a thread before responding
    to an early post. There are PCI bluetooth cards (at least one) as
    mentioned in a later post. See here:

    I am thinking of experimenting with seeing how far I can communcate with
    a small bluetooth-enabled GPS logger (Photomate, model 887). Hence my
    desire for bluetooth hardware with excellent transmit and receive
    capability, the ability to connect an external antenna, etc.

    I thought my only credible option was a PCI card (where size constraints
    would not limit the circuit design of the radio portion) and where an
    external antenna connection is assured.

    An outboard box (not a dongle) connected via USB also fits that

    No. I'm saying you shouldn't expect miracles out of a new dongle + antenna.
    Take my advice it or leave it [I think I can guess which you'll do].

    What the hell bug crawled up your ass and died?

    Why are you getting so bent out of shape at the concept that maybe, just
    maybe, it just might be possible to build a bluetooth transceiver with
    significantly more range than a puney thumb-nail-sized usb stub if
    you're not limited to a device envelope the size of a puney
    thumb-nale-sized usb stub?
